It must be *possible* for the *I think* to accompany all my representations: for otherwise something would be represented within me that could not be thought at all, in other words, the representation would either be impossible, or at least would be nothing to me. That representation which can be given prior to all thought is called *intuition*, and all the manifold of intuition has, therefore, a necessary relation to the *I think* in the same subject in which this manifold of intuition is found. This representation (the *I think*), however, is an act of *spontaneity*, that is, it cannot be considered as belonging to sensibility. I call it *pure apperception*, in order to distinguish it from empirical apperception, as also from original apperception, because it is that self-consciousness which, by producing the representations, *I think* (which must be capable of accompanying all other representations, and which is one and the same in all consciousness), cannot itself be accompanied by any further representations. I also call the unity of apperception the *transcendental* unity of self-consciousness, in order to indicate that *a priori* knowledge can be obtained from it. For the manifold representations given in an intuition would not one and all be *my* representations, if they did not all belong to one self-consciousness. What I mean is that, as my representations (even though I am not conscious of them as that), they must conform to the condition under which alone they *can* stand together in one universal self-consciousness, because otherwise they would not one and all belong to me. From this original combination much can be inferred.The thoroughgoing identity of the apperception of a manifold that is given in intuition contains a synthesis of representations, and is possible only through the consciousness of this synthesis. For the empirical consciousness which accompanies different representations is itself dispersed and without reference to the identity of the subject. Such a reference comes about, not simply through my accompanying every representation with consciousness, but through my *adding* one representation to another and being conscious of the synthesis of them. Only because I am able to combine a manifold of given representations *in one consciousness* is it possible for me to represent to myself the *identity of the consciousness in these representations*, that is, only under the presupposition of some *synthetic* unity of apperception is the *analytic* unity of apperception possible. The thought that the representations given in intuition belong one and all *to me*, is therefore the same as the thought that I unite them in one self-consciousness, or can at least do so; and although that thought itself is not yet the consciousness of the synthesis of representations, it nevertheless presupposes the possibility of this synthesis. In other words, it is only because I am able to comprehend the manifold of representations in one consciousness that I call them one and all *my* representations. For otherwise I should have as many-coloured and varied a self as I have representations of which I am conscious. Synthetic unity of the manifold of intuitions, as given *a priori*, is thus the ground of the identity of apperception itself, which precedes *a priori* all *my* determinate thought. Combination, however, does not lie in the objects, and cannot be borrowed from them by perception and thus first be taken into the understanding. It is, rather, solely an act of the understanding, which itself is nothing but the faculty of combining *a priori* and of bringing the manifold of given representations under the unity of apperception; and the principle of this unity is, in fact, the supreme principle of all human knowledge."—from_Critique of Pure Reason_.

In consequence of the inevitably scattered and fragmentary nature of our thinking, which has been mentioned, and of the mixing together of the most heterogeneous representations thus brought about and inherent even in the noblest human mind, we really possess only *half a consciousness*. With this we grope about in the labyrinth of our life and in the obscurity of our investigations; bright moments illuminate our path like flashes of lighting. But what is to be expected generally from heads of which even the wisest is every night the playground of the strangest and most senseless dreams, and has to take up its meditations again on emerging from these dreams? Obviously a consciousness subject to such great limitations is little fitted to explore and fathom the riddle of the world; and to beings of a higher order, whose intellect did not have time as its form, and whose thinking therefore had true completeness and unity, such an endeavor would necessarily appear strange and pitiable. In fact, it is a wonder that we are not completely confused by the extremely heterogeneous mixture of fragments of representations and of ideas of every kind which are constantly crossing one another in our heads, but that we are always able to find our way again, and to adapt and adjust everything. Obviously there must exist a simple thread on which everything is arranged side by side: but what is this? Memory alone is not enough, since it has essential limitations of which I shall shortly speak; moreover, it is extremely imperfect and treacherous. The *logical ego*, or even the *transcendental synthetic unity of apperception*, are expressions and explanations that will not readily serve to make the matter comprehensible; on the contrary, it will occur to many that“Your wards are deftly wrought, but drive no bolts asunder.”Kant’s proposition: “The *I think* must accompany all our representations ,” is insufficient; for the “I” is an unknown quantity, in other words, it is itself a mystery and a secret. What gives unity and sequence to consciousness, since by pervading all the representations of consciousness, it is its substratum, its permanent supporter, cannot itself be conditioned by consciousness, and therefore cannot be a representation. On the contrary, it must be the *prius* of consciousness, and the root of the tree of which consciousness is the fruit. This, I say, is the *will*; it alone is unalterable and absolutely identical, and has brought forth consciousness for its own ends. It is therefore the will that gives unity and holds all its representations and ideas together, accompanying them, as it were, like a continuous ground-bass. Without it the intellect would have no more unity of consciousness than has a mirror, in which now one thing now another presents itself in succession, or at most only as much as a convex mirror has, whose rays converge at an imaginary point behind its surface. But it is *the will* alone that is permanent and unchangeable in consciousness. It is the will that holds all ideas and representations together as means to its ends, tinges them with the colour of its character, its mood, and its interest, commands the attention, and holds the thread of motives in its hand. The influence of these motives ultimately puts into action memory and the association of ideas. Fundamentally it is the will that is spoken of whenever “I” occurs in a judgement. Therefore, the will is the true and ultimate point of unity of consciousness, and the bond of all its functions and acts. It does not, however, itself belong to the intellect, but is only its root, origin, and controller."—from_The World as Will and Representation_. Translated from the German by E. F. J. Payne in two volumes: volume II, pp. 139-140
Ontically, of course, Dasein is not only close to us―even that which is closest: we *are* it, each of us, we ourselves. In spite of this, or rather for just this reason, it is ontologically that which is farthest. To be sure, its ownmost Being is such that it has an understanding of that Being, and already maintains itself in each case as if its Being has been interpreted in some manner. But we are certainly not saying that when Dasein's own Being is thus interpreted pre-ontologically in the way which lies closest, this interpretation can be taken over as an appropriate clue, as if this way of understanding Being is what must emerge when one's ownmost state of Being is considered as an ontological theme. The kind of Being which belongs to Dasein is rather such that, in understanding its own Being, it has a tendency to do so in terms of that entity towards which it comports itself proximally and in a way which is essentially constant―in terms of the 'world'. In Dasein itself, and therefore in its own understanding of Being, the way the world is understood is, as we shall show, reflected back ontologically upon the way in which Dasein itself gets interpreted.Thus because Dasein is ontico-ontologically prior, its own specific state of Being (if we understand this in the sense of Dasein's 'categorial structure') remains concealed from it. Dasein is ontically 'closest' to itself and ontologically farthest; but pre-ontologically it is surely not a stranger."―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, pp. 36-37
The *second task* consists in distinguishing the mode of knowing operative in ontology as science of Being, and this requires us to *work out the methodological structure of ontological-transcendental differentiation*. In early antiquity it was already seen that Being and its attributes in a certain way underlie beings and precede them and so are *a proteron*, an earlier. The term denoting this character by which Being precedes beings is the expression *a priori*, *apriority*, being earlier or prior. As *a priori*, Being is earlier than beings. The meaning of this *a priori*, the sense of the earlier and its possibility, has never been cleared up. The question has not even once been raised as to why the determinations of Being and Being itself must have this character of priority and how such priority is possible. To be earlier is a determination of time, but it does not pertain to the temporal order of the time that we measure by the clock; rather, it is an earlier that belongs to the "inverted world." Therefore, this earlier which characterises Being is taken by the popular understanding to be the later. Only the interpretation of Being by way of temporality can make clear why and how this feature of being earlier, apriority, goes together with Being. The *a priori* character of Being and of all the structures of Being accordingly calls for a specific kind of approach and way of apprehending Being―*a priori cognition*.The basic components of *a priori* cognition constitute what we call *phenomenology*. Phenomenology is the name for the method of ontology, that is, of scientific philosophy. Rightly conceived, phenomenology is the concept of a method. It is therefore precluded from the start that phenomenology should pronounce any theses about Being which have specific content, thus adopting a so-called standpoint." ―Martin Heidegger, from_The Basic Problems of Phenomenology_
Because they are assertions about Being in the light of time properly understood, all ontological propositions are Temporal propositions. It is only because ontological propositions are Temporal propositions that they can and must be *a priori propositions*. It is only because ontology is a Temporal science that something like the *a priori* appears in it. *A priori* means "from the earlier" or "the earlier." "*Earlier*" is patently a *time-determination*. If we have been observant, it must have occurred to us that in our explications we employed no word more frequently than the expression "already." It "already antecedently" lies at the ground: "it must always already be understood beforehand": where beings are encountered, Being has "already beforehand" been projected. In using all of these temporal, really Temporal, terms we have in mind something that the tradition since Plato calls the *a priori*, even if it may not use the very term itself. In the preface to his *Metaphysische Anfangsgründe der Naturwissenschaft [Metaphysical principles of natural science], Kant says: "Now to cognize something *a priori* means to cognize it from its mere possibility." Consequently, *a priori* means that which makes beings as beings possible in *what* and *how* they are. But why is this possibility labeled by the term "earlier"? Obviously not because we recognize it earlier than beings. For what we experience first and foremost is beings, that which is; we recognize Being only later or maybe even not at all. This time-determination "earlier" cannot refer to the temporal order given by the common concept of time in the sense of intratemporality. On the other hand, it cannot be denied that a time determination is present in the concept of the *a priori*, the earlier. But, because it is not seen how the interpretation of Being necessarily occurs in the horizon of time, the effort has to be made to explain away the time determination by means of the *a priori*. Some go so far as to say that the *a priori*―the essentialities, the determination of beings in their Being―is extratemporal, supratemporal, timeless. That which does the enabling, the possibilities are characterized by a time-determination, the earlier, because in this *a priori* nothing of time is supposed to be present, hence *locus a non lucendo*? Believe it if you wish."―from_The Basic Problems of Phenomenology_
On the other hand, it is also characteristic of the state of philosophical inquiry today and has been for a long time that, while there has been extensive controversy about whether or not the *a priori* can be known, it has never occurred to the protagonists to ask first what could really have been meant by the fact that a time-determination turns up here and why it must turn up at all. To be sure, as long as we orient ourselves toward the common concept of time we are at an impasse, and negatively it is no less than consistent to deny dogmatically that the *a priori* has anything to do with time. However, time in the sense commonly understood, which is our topic here, is indeed only one derivative, even if legitimate, of the original time, on which the Dasein's ontological constitution is based. *It is only by means of the Temporality of the understanding of Being that it can be explained why the ontological determinations of Being have the character of apriority*. We shall attempt to sketch this briefly, as far as it permits of being done along general lines.We have just seen that all comportment toward beings already understands Being, and not just incidentally: Being must necessarily be understood precursorily (pre-cecently). The possibility of comportment toward beings demands a precursory understanding of Being, and the possibility of the understanding of Being demands in its turn a precursory projection upon time. But where is the final stage of this demand for ever further precursory conditions? It is temporality itself as the basic constitution of the Dasein. Temporality, due to its horizonal-ecstatic nature, makes possible *at once* the understanding of Being and comportment toward beings; therefore, that which does the enabling as well as the enablings themselves, that is, the possibilities in the Kantian sense, are "temporal," that is to say, Temporal, in their specific interconnection. Because the original determinant of possibility, the origin of possibility itself, is time, time temporalizes itself as the absolutely earliest. *Time is earlier than any possible earlier* of whatever sort, because it is the basic condition for an earlier as such. And because time as the source of all enablings (possibilities) is the earliest, all possibilities as such in their possibility-making function have the character of the earlier. That is to say, they are *a priori*. But, from the fact that time is the earliest in the sense of being the possibility of every earlier and of every *a priori* foundational ordering, it does not follow that time is ontically the first being; nor does it follow that time is forever and eternal, quite apart from the impropriety of calling time a being at all.” ―from_The Basic Problems of Phenomenology_
As a method however, the *method of ontology* is nothing but the sequence of the steps involved in the approach to Being as such and the elaboration of its structures. We call this method of ontology *phenomenology*. In more precise language, phenomenological investigation is explicit effort applied to the method of ontology. However, such endeavors, their success or failure, depend primarily, in accordance with our discussion, on how far phenomenology has assured for itself the object of philosophy―how far, in accordance with its own principle, it is unbiased enough in the face of what the things themselves demand. We cannot now enter any further into the essential and fundamental constituent parts of this method. In fact, we have applied it constantly. What we would have to do would be merely to go over the course already pursued, but now with explicit reflection on it. But what is most essential is first of all to have traversed the whole path once, so as, for one thing, to learn to wonder scientifically about the mystery of things and, for another, to banish all illusions, which settle down and nest with particular stubbornness precisely in philosophy.There is no such thing as *the one* phenomenology, and if there could be such a thing it would never become anything like a philosophical technique. For implicit in the essential nature of all genuine method as a path toward the disclosure of objects is the tendency to order itself always toward that which it itself discloses. When a method is genuine and provides access to the objects, it is precisely then that the progress made by following it and the growing originality of the disclosure will cause the very method that was used to become necessarily obsolete. The only thing that is truly new in science and in philosophy is the genuine questioning and struggle with things which is at the service of this questioning." ―from_The Basic Problems of Phenomenology_
Our knowledge springs from two fundamental sources of our mind; the first is to receive representations (receptivity of impressions), the second is the faculty of knowing an object through these representations (spontaneity of concepts). Through the first an object is *given* to us, through the second the object is *thought* in relation to that representation (which is a mere determination of the mind). Intuition and concepts constitute, therefore, the elements of all our knowledge, so that neither concepts without an intuition in some way corresponding to them, nor intuition without concepts can yield knowledge. Both are either pure or empirical. They are empirical when they contain sensation (sensation presupposes the actual presence of the object). They are *pure* when no sensation is mixed in with the representation. Sensation may be called the matter of sensible knowledge. Pure intuition, therefore, contains only the form under which something is intuited, and the pure concepts contains only the form of thinking an object in general. Pure intuitions and pure concepts alone are possible *a priori*, empirical intuitions and empirical concepts only *a posteriori*. We call *sensibility* the *receptivity* of our mind to receive representations insofar as it is in some wise affected, while the *understanding*, on the other hand, is our faculty of producing representations by ourselves, or the *spontaneity* of knowledge. We are so constituted that our intuition can never be other than *sensible*; that is, it contains only the mode in which we are affected by objects. The faculty, on the contrary, which enables us to *think* the object of sensible intuition is the *understanding*. Neither of these properties is to be preferred to the other. Without sensibility no object would be given to us, without understanding no object would be thought. Thoughts without content are empty, intuitions without concepts are blind. It is, therefore, just as necessary to make our concepts sensible (i.e., to add the object to them in intuition) as to make our intuitions understandable (i.e., to bring them under concepts). These two faculties or capacities cannot exchange their functions. The understanding cannot intuit anything, the senses cannot think anything. Only from their union can knowledge arise. But this is no reason for confounding their respective contributions; rather, it gives us a strong reason for carefully separating and distinguishing the one from the other. We therefore distinguish the science of the rules of sensibility in general, i.e., aesthetic, from the science of the rules of the understanding in general, i.e., logic."―Transcendental Doctrine of Elements. Transcendental Logic: The Idea of a Transcendental Logic
In Leibniz we can already find the striking observation that *cogitatur ergo est* is no less evident than *cogito ergo sum*. Naturally, *est* here does not mean existence or reality but being of whatever kind and form, including even ideal being, fictive being, conscious-being [*Bewusst-Sein*], etc. However, we must go even beyond this thesis of Leibniz. The correlate of the act of *cogitatio* is not, as Leibniz said, being simply, but only that type of being we call "objectifiable being." Objectifiable being must be sharply distinguished from the non-objectifiable being of an act, that is, from a kind of entity which possesses its mode of being only in performance [*Vollzug*], namely, in the performance of the act. "Being," in the widest sense of the word, belongs indeed to the being-of-an-act [*Akt-Sein*], to *cogitare*, which does not in turn require another *cogitare*. Similarly, we are only vaguely "aware" of our drives [*Triebleben*] without having them as objects as we do those elements of consciousness which lend themselves to imagery. For this reason the first order of evidence is expressed in the principle, "There is something," or, better, "There is not nothing." Here we understand by the word "nothing" the negative state of affairs of not-being in general rather than "not being something" or "not being actual." A second principle of evidence is that everything which "is" in any sense of the possible kinds of being can be analyzed in terms of its character or essence (not yet separating its contingent characteristics from its genuine essence) and its existence in some mode. With these two principles we are in a position to define precisely the concept of knowledge, a concept which is prior even to that of consciousness. Knowledge is an ultimate, unique, and underivable ontological relationship between two beings. I mean by this that any being A "knows" any being B whenever A participates in the essence or nature of B, without B's suffering any alteration in its nature or essence because of A's participation in it. Such participation is possible both in the case of objectifiable being and in that of active [*akthaften*] being, for instance, when we repeat the performance of the act; or in feelings, when we relive the feelings, etc. The concept of participation is, therefore, wider than that of objective knowledge, that is, knowledge of objectifiable being. The participation which is in question here can never be dissolved into a causal relation, or one of sameness and similarity, or one of sign and signification; it is an ultimate and essential relation of a peculiar type. We say further of B that, when A participates in B and B belongs to the order of objectifiable being, B becomes an "objective being" ["*Gegenstand"-sein*]. Confusing the being of an object [*Sein des Gegenstandes*] with the fact that an entity is an object [*Gegenstandssein eines Seienden*] is one of the fundamental errors of idealism. On the contrary, the being of B, in the sense of a mode of reality, never enters into the knowledge-relation. The being of B can never stand to the real bearer of knowledge in any but a causal relation. The *ens reale* remains, therefore, outside of every possible knowledge-relation, not only the human but also the divine, if such exists. Both the concept of the "intentional act" and that of the "subject" of this act, an "I" which performs acts, are logically posterior. The intentional act is to be defined as the process of becoming [*Werdesein*] in A through which A participates in the nature or essence of B, or that through which this participation is produced. To this extent the Scholastics were right to begin with the distinction between an *ens intentionale* and an *ens reale*, and then, on the basis of this distinction, to distinguish between an intentional act and a real relation between the knower and the being of the thing known." ―from_Idealism and Realism_
One of my principal theses is that in every case the nature of a being (contingent as well as essential nature) can, in principle, be immanent to and truly inherent in knowledge and reflexive consciousness as it is outside of consciousness, and therefore not only as it is represented by some image, perception, idea [*Vorstellung*], or thought. This immanence of the nature of a being to consciousness occurs, of course, with totally different degrees of adequation and on completely different levels of the relativity of its existence to the existence and constitution [*Organisation*] of the "knowing" subject. Existence, however, can never be immanent to consciousness. Rather, existence necessarily transcends knowledge and consciousness and is alien to them. Existence is essentially transcendent and remains independent of them, even in the limiting case of a "divine," omniscient Mind." In other words, the nature and the existence of any possible object are separable with respect to the possibility of their being *in mente* [in the mind]. The nature of a being can be *in mente* and actually is so in any evidential cognition of what a thing is, which excludes cases of illusion and error. Existence can never be *in mente*. I shall speak later of how existence can be "given" despite this. Existence transcends thought, intuition, and perception, as well as any cooperation of thought and intuition in that higher form of knowledge we call cognition. Cognition is the "knowledge of something as something," the coincidence [*Deckung*] of intuition and thought." from_Idealism and Realism_
Only after the concept of knowledge has been based on an ontological relation [*Seinsverhältnis*] can we work out the particular kind of being from which the principle of immanence-to-consciousness (the starting point of Idealism and Critical Realism) mistakenly proceeds as though from a primary insight. This is the being of "being-conscious" [*Bewusst-Seins*]. All being-conscious must first of all be brought under the higher concept of ideal being, or, at all events, that of irreal being. The mental item which presents itself in the experiences of consciousness may be real; being-conscious itself never is. However, the concept of consciousness is derivative in not only this sense. Consciousness also presupposes the concept of knowledge. Nothing is more misleading than to proceed in the opposite direction and define knowledge itself as simply a particular "content of consciousness," as we see if we oppose, to the particular kind of knowing and having-known which we call consciousness, another kind of knowledge which precedes it and includes no form of being-conscious. We will call this knowledge *ecstatic* [*ekstatische*] knowledge. It is found quite clearly in animals, primitive people, children, and, further, in certain pathological and other abnormal and supra-normal states (e.g., in recovering from the effects of a drug). I have said elsewhere that the animal never relates to its environment as to an object but only *lives in it* [*es lebe nur "in sie hinein*"]. Its conduct with respect to the external world depends upon whether the latter satisfies its instinctive drives or denies them satisfaction. The animal experiences the surrounding world as resistances of various types. Hence, it is absolutely necessary to contest the principle (in Descartes, Franz Brentano, *et al*.) that every mental function and act is accompanied by an immediate knowledge of it. An even more highly contestable principle is that a relation to the self is an essential condition of all processes of knowledge. It is difficult to reproduce purely ecstatic knowledge in mature, civilized men, whether in memory, reverie, perception, thought, or empathetic identification with things, animals, or men; nonetheless, there is no doubt that in every perception and presentation of things and events we think that we grasp *the things-themselves*, not mere "images" of them or representatives of some sort.Knowledge first becomes conscious knowledge [*Bewusst-sein*], that is, comes out of its original ecstatic form of simply "having" things, in which there is no knowledge of the having or of that through which and in which it is had, when the act of being thrown back on the self (probably only possible for men) comes into play. This act grows out of conspicuous resistances, clashes, and oppositions―in sum, out of pronounced suffering. It is the *actus re-flexivus* in which knowledge of the knowledge of things is added to the knowledge of things. Furthermore, in this act we come to know the kind of knowledge we have, for example, memory, ideation, and perception, and finally, beyond even these, we come to have a knowledge of the relation of the act performed to the self, to the knower. With respect to any specific relation to the self, this last knowledge, so-called conscious self-knowledge, comes only after knowledge about the act. Kant's principle that an "I think" must be *able* to accompany all a man's thoughts may be correct. That it in fact always accompanies them is nevertheless undoubtedly false. However, the kind of being (indeed, of ideal being) which contents possess when they are reflexively *had* in their givenness in conscious acts―when, therefore, they become reflexive―is the being of being-consciously-known."from_Idealism and Realism_
There appears to be a fifth way, that of eminence. According to this I argue that it is incompatible with the idea of a most perfect being that anything should excel it in perfection (from the corollary to the fourth conclusion of the third chapter) . Now there is nothing incompatible about a finite thing being excelled in perfection; therefore, etc. The minor is proved from this, that to be infinite is not incompatible with being; but the infinite is greater than any finite being. Another formulation of the same is this. That to which intensive infinity is not repugnant is not all perfect unless it be infinite, for if it is finite, it can be surpassed, since infinity is not repugnant to it. But infinity is not repugnant to being, therefore the most perfect being is infinite.The minor of this proof, which was used in the previous argument, [1] cannot, it seems, be proven *a priori*. For, just as contradictories by their very nature contradict each other and their opposition cannot be made manifest by anything more evident, so also these terms [viz. "being" and "infinite"] by their very nature are not repugnant to each other. Neither does there seem to be any way of proving this except by explaining the meaning of the notions themselves. "Being" cannot be explained by anything better known than itself. "Infinite" we understand by means of finite. I explain "infinite" in a popular definition as follows: The infinite is that which exceeds the finite, not exactly by reason of any finite measure, but in excess of any measure that could be assigned.—[2] The following persuasive argument can be given for what we intend to prove. Just as everything is assumed to be possible if its impossibility is not apparent, so also all things are assumed to be compatible if their incompatibility is not manifest. Now there is no incompatibility apparent here, for it is not of the nature of being to be finite; nor does finite appear to be an attribute coextensive with being. But if they were mutually repugnant, it would be for one or the other of these reasons. The coextensive attributes which being possesses seem to be sufficiently evident.—[3] A third persuasive argument is this. Infinite in its own way is not opposed to quantity (that is, where parts are taken successively); therefore, neither is infinity, in its own way, opposed to entity (that is, where perfection exists simultaneously) .—[4] If the quantity characteristic of power is simply more perfect than that characteristic of mass, why is it possible to have an infinity [of parts] in mass and not an infinite power? And if an infinite power is possible, then it actually exists (from the fourth conclusion of the third chapter).—[5] The intellect, whose object is being, finds nothing repugnant about the notion of something infinite. Indeed, the infinite seems to be the most perfect thing we can know. Now if tonal discord so easily displeases the ear, it would be strange if some intellect did not clearly perceive the contradiction between infinite and its first object [viz. being] if such existed. For if the disagreeable becomes offensive as soon as it is perceived, why is it that no intellect naturally shrinks from infinite being as it would from something out of harmony with, and even destructive of, its first object?"—from_A Treatise on God as First Principle_, 4.63-4.64
It will be seen how there can be the idea of a special science, the *critique of pure reason* as it may be called. For reason is the faculty which supplies the *principles* of *a priori* knowledge. Pure reason therefore is that which contains the principles of knowing something entirely *a priori*. An *organon* of pure reason would be the sum total of the principles by which all pure *a priori* knowledge can be acquired and actually established. Exhaustive application of such an organon would give us a system of pure reason. But as this would be a difficult task, and as at present it is still doubtful whether indeed an expansion of our knowledge is possible here at all, we may regard a science that merely judges pure reason, its sources and limits, as the *propaedeutic* to the system of pure reason. In general, it would have to be called only a *critique*, not a *doctrine* of pure reason. Its utility, in regard to speculation, would only be negative, for it would serve only to purge rather than to expand our reason, and, which after all is a considerable gain, would guard reason against errors. I call all knowledge *transcendental* which deals not so much with objects as with our manner of knowing objects insofar as this manner is to be possible *a priori*. A system of such concepts would be called *transcendental philosophy*. But this is still, as a beginning, too great an undertaking. For since such a science must contain completely both analytic and synthetic *a priori* knowledge, it is, as far as our present purpose is concerned, much too comprehensive. We will be satisfied to carry the analysis only so far as is indispensably necessary in order to understand in their whole range the principles of *a priori* synthesis, with which alone we are concerned. This investigation, which properly speaking should be called only a transcendental critique but not a doctrine, is all we are dealing with at present. It is not meant to expand our knowledge but only to correct it, and to become the touchstone of the value, or lack of value, of all *a priori* knowledge. Such a critique is therefore the preparation, as far as possible, for a new organon, or, if this should turn out not to be possible, for a canon at least, according to which, thereafter, the complete system of a philosophy of pure reason, whether it serve as an expansion or merely as a limitation of its knowledge, may be carried out both analytically and synthetically. That such a system is possible, indeed that it need not be so comprehensive as to cut us off from the hope of completing it, may already be gathered from the fact that it would have to deal not with the nature of things, which is inexhaustible, but with the understanding which makes judgments about the nature of things, and with this understanding again only as far as its *a priori* knowledge is concerned. The supply of this *a priori* knowledge cannot be hidden from us, as we need not look for it outside the understanding, and we may suppose this supply to prove sufficiently small for us to record completely, judge as to its value or lack of value and appraise correctly. Still less ought we to expect here a critique of books and systems of pure reason, but only the critique of the faculty of pure reason itself. Only once we are in possession of this critique do we have a reliable touchstone for estimating the philosophical value of old and new works on this subject. Otherwise, an unqualified historian and judge does nothing but pass judgments upon the groundless assertions of others by means of his own, which are equally groundless.
It is very important to note that the transcendence of the object is by no means a primitive component necessarily ingredient in all knowledge. It is missing in all ecstatic knowledge. In ecstatic knowledge the known world is still not objectively given. Only when the (logically and genetically simultaneous) act furnishing ecstatic knowledge and the subject which performs this act become themselves the content of knowledge in the act of reflection does the character originally given in ecstatic knowledge become a mere reference pointing to the “object.” It is only here that the object or that which turns into an object remains from now on “transcendent” to consciousness. Therefore, whenever there is consciousness, objects transcendent to consciousness must also be given to consciousness. Their structural relationship is indissoluble. Whenever self-consciousness and consciousness of an object arise, they do so simultaneously and through the same process. The categorical form of an object is not first impressed in a judgment upon a nonobjective given, not even in a one-term, simple judgment, as some people have thought (e.g., Heinrich Maier in his book *Wahrheit und Wirklichkeit*). This is a pure construction. Consciousness of an object precedes all judgment and is not originally constituted by judgment. The same holds true of consciousness of states of affairs. The consciousness of an object and the intentional object are not the result of an active [tätige] “forming” or “imprinting” which we perform on the given through judgments or any other operations of thought. On the contrary, they are the result of a pulling back, the result, that is, of the re-flexive act, in which an originally ecstatic [*ekstatisch gebender*] act turns back knowingly onto itself and comes upon a central self as its starting point. This central self can be given at every level and degree of “concentration” and “collectedness” in “self-consciousness.” What we had hold of [*das Gehabte*] remains “as” object, while the act of reflection turns the knowing back into the knower, as the result of a turning away [*Abwendung*] and a pulling back, and not of an active turning to [*Zuwendung*].From what has been said, one may very well imagine that the real world could be abolished without consciousness and the self being altered or abolished thereby. But this could in no way be the case with the world of objects that transcend consciousness. Descartes as well as Lotze misunderstood this. Where a *cogito* exists, there must also be a *cogitatur* in which a transcendent object is thought. Only a being capable of reflection (*reflexio*) and self-consciousness *can* have objects. Charlotte Bühler has recently made it seem probable that the infant does not yet possess objective consciousness. In waking from the effects of a drug we can follow the process by which the givenness of the surrounding world becomes objective again. There is one last point of contact between the problem of reality and the consciousness of transcendence. The consciousness of transcendence, as already indicated, shows how the mere ecstatic possession of reality on the level of the immediately experienced resistance of an X to the central drives of life passes over into a reflexive and thus objective possession of reality. And we find similar transitions between ecstatic remembering which is merged in the being of what is past and reflexive remembering, between ecstatic drive activities and recurrent deliberation [*Besinnung*], between ecstatic surrender to a value and objectification of a value, between identifying with an alter ego and “understanding” [*Verstehen*] another, however slightly.” ―from_Idealism and Realism_
The third preliminary problem for every theory of reality is that of the experience of transcendence. We saw in the case of Berkeley that his erroneous principle *percipi est esse*, and his assertion that any being which we think, just for the reason that it is thought, cannot at the same time be regarded as subsisting independently of thinking, incorporate a failure to recognize the consciousness of transcendence peculiar to all intentional acts. This is an instance of the failure to recognize that not only all thinking in the narrower sense, in the sense of grasping an object on the basis of “meanings” and grasping a state of affairs through judgments, but *every* intention in general, whether perception, representation, remembering, the feeling of value, or the posing of ends and goals, points beyond the act and the contents of the act and intends something other than the act [*ein Aktfremdes*], even when what is thought is in turn itself a thought. Indeed, *intentio* signifies a goal-directed movement toward something which one does not have oneself or has only partially and incompletely. Berkeley (following Locke, who was the first to make the basic philosophical error which introduced “psychologism” into epistemology) arrived at the principle *esse est percipi* by making the idea [*Vorstellung*] (and even the sensation) into a thing, an immaterial substance, and by failing to distinguish between the act, the content of an act, and the object. Furthermore, Berkeley confused the being of objects with the fact of being-an-object, even though the latter has only a loose and variable connection with the former. On the other hand, the transcendence of the intentional object with respect to both the *intentio* and its present content is common to every instance of being-an-object. It is, for instance, proper to objects of pure mathematics which are certainly not real but ideal (for example, the number 3). These are produced from the *a priori* material of intuition in accordance with an operational law governing the steps of our thought or intuition. Transcendence is further proper to all fictitious objects and even to contradictory objects, for instance, a square circle. All these sorts of objects, e.g., the golden mountain or Little Red Riding Hood, satisfy the basic principle of the transcendence of objects over and above that aspect of them which is, at any moment, given in consciousness, just as much as do real objects existing independently of all consciousness and knowledge."―from_Idealism and Realism_
It is precisely because the principle of the transcendence of the object is completely independent of the existential status of the objects themselves and, thus, independent of the question whether they are produced by us or subsist on their own―whether they are fictions or real beings―that the fact of the consciousness of transcendence is not even remotely qualified to solve the problem of reality. This has been misunderstood equally by W. Freytag, Edith Landmann, P. Linke, and even by Husserl himself. Indeed, people have wanted to speak of an intentional realism (E. Landmann) in contrast to Critical Realism and to all other forms of realism. N. Hartmann was quite correct in emphasizing, in opposition to this, that the projection [*Hinausragen*] of the intentional object beyond the content of consciousness and its act cannot make the least contribution to solving the problem of realism. If something is an intentional object, we cannot recognize from this fact alone, whether it is real or not. If the perceived cherry, the conceived triangle, a friend’s visit anticipated in a dream, Little Red Riding Hood, a freely planned project, or a felt value, have entirely different characteristics and predicates than do the mental processes and the actual contents in which these objects appear, then the distinction between intentional and mental holds equally of both the real and the irreal. *Thus, the problem of what is real is not touched by the fact of the transcendence of the object*, and *percipi est esse*, in Berkeley’s psychologistic sense, is laid to rest. This also frustrates attempts, such as Hume’s in his *Treatise*, to derive being-an-object in general―an object as distinguished from an idea―from a psychogenetic process in which the very ideas through which this psychogenetic process is supposed to be accomplished are themselves reified [*verdinglicht*]."―from_Idealism and Realism_
Science and philosophy have for centuries been sustained by unquestioning faith in perception. Perception opens a window on to things. This means that it is directed, quasi-teleologically, towards a *truth in itself* in which the reason underlying all appearances is to be found. The tacit thesis of perception is that at every instant experience can be co-ordinated with that of the previous instant and that of the following, and my perspective with that of other consciousnesses—that all contradictions can be removed, that monadic and intersubjective experience is one unbroken text—that what is now indeterminate for me could become determinate for a more complete knowledge, which is as it were realized in advance in the thing, or rather which is the thing itself. Science has first been merely the sequel or amplification of the process which constitutes perceived things. Just as the thing is the invariant of all sensory fields and of all individual perceptual fields, so the scientific concept is the means of fixing and objectifying phenomena. Science defined a theoretical state of bodies not subject to the action of any force, and *ipso facto* defined force, reconstituting with the aid of these ideal components the processes actually observed. It established statistically the chemical properties of pure bodies, deducing from these those of empirical bodies, and seeming thus to hold the plan of creation or in any case to have found a reason immanent in the world. The notion of geometrical space, indifferent to its contents, that of pure movement which does not by itself affect the properties of the object, provided phenomena with a setting of inert existence in which each event could be related to physical conditions responsible for the changes occurring, and therefore contributed to this freezing of being which appeared to be the task of physics. In thus developing the concept of the thing, scientific knowledge was not aware that it was working on a presupposition. Precisely because perception, in its vital implications and prior to any theoretical thought, is presented as perception of a being, it was not considered necessary for reflection to undertake a genealogy of being, and it was therefore confined to seeking the conditions which make being possible. Even if one took account of the transformations of determinant consciousness, even if it were conceded that the constitution of the object is never completed, there was nothing to add to what science said of it; the natural object remained an ideal unity for us and, in the famous words of Lachelier, a network of general properties. It was no use denying any ontological value to the principles of science and leaving them with only a methodical value, for this reservation made no essential change as far as philosophy was concerned, since the sole conceivable being remained defined by scientific method. The living body, under these circumstances, could not escape the determinations which alone made the object into an object and without which it would have had no place in the system of experience. The value predicates which the reflecting judgment confers upon it had to be sustained, in being, by a foundation of physico-chemical properties. In ordinary experience we find a fittingness and a meaningful relationship between the gesture, the smile and the tone of a speaker. But this reciprocal relationship of expression which presents the human body as the outward manifestation of a certain manner of being-in-the-world, had, for mechanistic physiology, to be resolved into a series of causal relations.”—from_Phenomenology of Perception_. Translated by Colin Smith, pp. 62-64—Artwork by Cristian Boian
We also find *physics*, in the widest sense of the word, concerned with the explanation of phenomena in the world; but it lies already in the nature of the explanations themselves that they cannot be sufficient. *Physics* is unable to stand on its own feet, but needs a *metaphysics* on which to support itself, whatever fine airs it may assume towards the latter. For it explains phenomena by something still more unknown than are they, namely by laws of nature resting on forces of nature, one of which is also the vital force. Certainly the whole present condition of all things in the world or in nature must necessarily be capable of explanation from purely physical causes. But such an explanation―supposing one actually succeeded so far as to be able to give it―must always just as necessarily be burdened with two essential imperfections (as it were with two sore points, or like Achilles with the vulnerable heel, or the devil with the cloven foot). On account of these imperfections, everything so explained would still really remain unexplained. The first imperfection is that the *beginning* of the chain of causes and effects that explains everything, in other words, of the connected and continuous changes, can positively *never* be reached, but, just like the limits of the world in space and time, recedes incessantly and *in infinitum*. The second imperfection is that all the efficient causes from which everything is explained always rest on something wholly inexplicable, that is, on the original *qualities* of things and the *natural forces* that make their appearance in them. By virtue of such forces they produce a definite effect, e.g., weight, hardness, impact, elasticity, heat, electricity, chemical forces, and so on, and such forces remain in every given explanation like an unknown quantity, not to be eliminated at all, in an otherwise perfectly solved algebraical equation. Accordingly there is not a fragment of clay, however little its value, that is not entirely composed of inexplicable qualities. Therefore these two inevitable defects in every purely physical, i.e., causal, explanation indicate that such an explanation can be only *relatively* true, and that its whole method and nature cannot be the only, the ultimate and hence sufficient one, in other words, cannot be the method that will ever be able to lead to the satisfactory solution of the difficult riddles of things, and to the true understanding of the world and of existence; but that the *physical* explanation, in general and as such, still requires one that is *metaphysical*, which would furnish the key to all its assumptions, but for that very reason would have to follow quite a different path. The first step to this is that we should bring to distinct consciousness and firmly retain the distinction between the two, that is, the difference between *physics* and *metaphysics*. In general this difference rests on the Kantian distinction between *phenomenon* and *thing-in-itself*. Just because Kant declared the thing-in-itself to be absolutely unknowable, there was, according to him, no *metaphysics* at all, but merely immanent knowledge, in other words mere *physics*, which can always speak only of phenomena, and together with this a critique of reason which aspires to metaphysics."―from_The World as Will and Representation_. Translated from the German by E. F. J. Payne. In Two Volumes, Volume II, pp. 172-173
Metaphysics, a completely isolated and speculative branch of rational knowledge which is raised above all teachings of experience and rests on concepts only (not, like mathematics, on their application to intuition), in which reason therefore is meant to be its own pupil, has hitherto not had the good fortune to enter upon the secure path of a science, although it is older than all other sciences, and would survive even if all the rest were swallowed up in the abyss of an all-destroying barbarism. Reason in metaphysics, even if it tries, as it professes, only to gain *a priori* insight into those laws which are confirmed by our most common experience, is constantly being brought to a standstill, and we are obliged again and again to retrace our steps, as they do not lead us where we want to go. As to unanimity among its participants, there is so little of it in metaphysics that it has rather become an arena that would seem especially suited for those who wish to exercise themselves in mock fights, where no combatant has as yet succeeded in gaining even an inch of ground that he could call his permanent possession. There cannot be any doubt, therefore, that the method of metaphysics has hitherto consisted in a mere random groping, and, what is worst of all, in groping among mere concepts.What, then, is the reason that this secure scientific course has not yet been found? Is this, perhaps, impossible? Why, in that case, should nature have afflicted our reason with the restless aspiration to look for it, and have made it one of its most important concerns? What is more, how little should we be justified in trusting our reason, with regard to one of the most important objects of which we desire knowledge, it not only abandons us, but lures us on by delusions, and in the end betrays us! Or, if hitherto we have only failed to meet with the right path, what indications are there to make us hope that, should we renew our search, we shall be more successful than others before us?"―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, p. 17
A similar experiment may be tried in metaphysics as regards the *intuition* of objects. If the intuition had to conform to the constitution of objects, I would not understand how we could know anything of them *a priori*; but if the object (as object of the senses) conformed to the constitution of our faculty of intuition, I could very well conceive such a possibility. As, however, I cannot rest in these intuitions if they are to become knowledge, but have to refer them as representations, to something as their object, and must determine this object through them, I can assume either that the *concepts* through which I arrive at this determination also conform to the object, and I would again be as perplexed about how I can know anything about it *a priori*; or else that the objects, or what is the same thing, the *experience* in which alone they are known (as objects that are given to us), conform to those concepts. In the latter case, I recognize an easier solution because experience itself is a kind of knowledge that requires understanding; and this understanding has its rules which I must presuppose as existing within me even before objects are given to me, and hence *a priori*. These rules are expressed in *a priori* concepts to which all objects of experience must necessarily conform, and with which they must agree. With regard to objects, insofar as they are thought merely through reason and thought indeed as necessary, and which can never, at least not in the way in which reason thinks them, be given in experience, the attempts at thinking them (for they must admit of being thought) will subsequently furnish an excellent touchstone of what we are adopting as our new method of thought, namely, that we know of things *a priori* only that which we ourselves put into them."―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 18-19
This experiment succeeds as hoped and promises to metaphysics, in its first part, which deals with those *a priori* concepts to which the corresponding objects may be given in experience, the secure course of a science. For by thus changing our point of view, the possibility of *a priori* knowledge can well be explained, and, what is still more, the laws which *a priori* lie at the foundation of nature, as the sum total of the objects of experience, may be supplied with satisfactory proofs, neither of which was possible within the procedure hitherto adopted. But there arises from this deduction of our faculty of knowing *a priori*, as given in the first part of metaphysics, a somewhat startling result, apparently most detrimental to that purpose of metaphysics which has to be treated in its second part, namely the impossibly of using this faculty to transcend the limits of possible experience, which is precisely the most essential concern of the science of metaphysics. But here we have exactly the experiment which, by disproving the opposite, establishes the truth of the first estimate of our *a priori* rational knowledge, namely, that it is directed only at appearances and must leave the thing in itself as real for itself but unknown to us. For that which necessarily impels us to to go beyond the limits of experience and of all appearances is the *unconditioned*, which reason rightfully and necessarily demands, aside from everything conditioned, in all things in themselves, so that the series of conditions be completed. If, then, we find that, under the supposition that our empirical knowledge conforms to objects as things in themselves, the unconditioned *cannot be thought without contradiction*, while under the supposition that our representation of things as they are given to us does not conform to them as things in themselves, but, on the contrary, that these objects as appearance conform to our mode of representation, then *the contradiction vanishes*; and if we find, therefore, that the unconditioned cannot be encountered in things insofar as we are acquainted with them (insofar as they are given to us), but only in things insofar as we are not acquainted with them, that is, insofar as they are things in themselves; then it becomes apparent that what we at first assumed only for the sake of experiment is well founded. However, with speculative reason unable to make progress in the field of the supersensible, it is still open to us to investigate whether in reason's practical knowledge data may not be found which would enable us to determine that transcendent rational concept of the unconditioned, so as to allow us, in accordance with the wish of metaphysics, to get beyond the limits of all possible experience with our *a priori* knowledge, which is possible in practical matters only. Within such a procedure, speculative reason has always at least created a space for such an expansion, even if it has to leave it empty; none the less we are at liberty, indeed we are summoned, to fill it, if we are able to do so, with practical *data* of reason."―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 19-21
The purpose of this critique of pure speculative reason consists in the attempt to change the old procedure of metaphysics, and to bring about a complete revolution after the example set by geometers and investigators of nature. This critique is a treatise on the method, not a system of the science itself; but nevertheless it marks out the whole plan of this science, both with regard to its limits and with regard to its inner organization. For it is peculiar to pure speculative reason that it is able, indeed bound, to measure its own powers according to the different ways in which it chooses its objects for thought, and to enumerate exhaustively the different ways of choosing its problems, thus tracing a complete outline of a system of metaphysics. This is due to the fact that, with regard to the first point, nothing can be attributed to objects in *a priori* knowledge, except what the thinking subject takes from within itself; while, with regard to the second point, pure reason, as far as its principles of knowledge are concerned, forms a separate and independent unity, in which, as in an organized body, every member exists for the sake of all the others, and all the others exist for the sake of the one, so that no principle can be safely applied in *one* relation unless it has been carefully examined in *all* its relations to the whole use of pure reason. Hence, too, metaphysics has this singular advantage, an advantage which cannot be shared by any other rational science which has to deal with objects (for *logic* deals only with the form of thought in general), that if by means of this critique it has been set upon the secure course of a science, it can exhaustively grasp the entire field of knowledge pertaining to it, and can thus finish its work and leave it to posterity as a capital that can never be added to, because it has to deal only with principles and with the limitations of their use, as determined by these principles themselves. And this completeness becomes indeed an obligation if metaphysics is to be a fundamental science, of which we must be able to say, *nil actum reputants, si quid superesset agendum* [to think that nothing was done for as long as something remained to be done]." ―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 21-22
What is gained by the transcendence of the object is the identifiability of the object in a plurality of acts and the identifiability of what is thought by several individuals. This identifiability is not restricted to ideal objects, which are generated according to a definite operational law and are therefore producible by everyone out of the same material of intuition which is given prior to any particular sense-experience. The identifiability obtains in precisely the same way for objects of myth and folklore, of belief and artistic fantasy. Goethe’s Faust, Apollo, and Little Red Riding Hood can be identified by several individuals and are the objects of common, universally valid statements. Indeed, exact identity of the nature of the object in question and evidential knowledge of this identity can occur *only* in the case of ideal objects. Our certainty that we all think the same number 3 in the strictest identity of its nature is much more evident than that we all think the same real object, a tree, for instance. In the case of real objects we can actually prove that it is impossible for the momentary content in which the object is represented and thought to be exactly the same in a plurality of acts and for many individuals. The only other contribution made by the fact of the consciousness of transcendence, so long overlooked in recent philosophy, to the problem of reality is this: the acts in which this consciousness is present can bring the givenness of reality, of which we shall speak later, into “objective” form, and can therefore elevate that which is given in this way as real to the status of a real “object.” But with this, the contribution of the consciousness of transcendence to the problem of reality is at an end. Although N. Hartmann made the same point with respect to Paul Linke’s otherwise shrewd and pertinent comments on his doctrine of reality, still we should emphasize that the transcendence of the object does not *exclude* the reality of the object, not even of the *same* object in the strict sense of “same.” ―from_Idealism and Realism_
In provisionally characterizing the object which serves as the theme of our investigation (the Being of entities, or the meaning of Being in general), it seems that we have also delineated the method to be employed. The task of ontology is to explain Being itself and to make the Being of entities stand out in full relief. And the method of ontology remains questionable in the highest degree as long as we merely consult those ontologies which have come down to us historically, or other essays of that character. Since the term "ontology" is used in this investigation in a sense which is formally broad, any attempt to clarify the method of ontology by tracing its history is automatically ruled out. When, moreover, we use the term "ontology," we are not talking about some definite philosophical discipline standing in interconnection with the others. Here one does not have to measure up to the tasks of some discipline that has been presented beforehand; on the contrary, only in terms of the objective necessities of definite questions and the kind of treatment which the 'things themselves' require, can one develop such a discipline. With the question of the meaning of Being, our investigation comes up against the fundamental question of philosophy. This is one that must be treated *phenomenologically*. Thus our treatise does not subscribe to a 'standpoint' or represent any special 'direction'; for phenomenology is nothing of either sort, nor can it become so as long as it understands itself. The expression 'phenomenology' signifies primarily a *methodological conception*. This expression does not characterize the what of the objects of philosophical research as subject-matter, but rather the *how* of that research. The more genuinely a methodological concept is worked out and the more comprehensively it determines the principles on which a science is to be conducted, all the more primordially is it rooted in the way we come to terms with the things themselves, and the farther is it removed from what we call "technical devices," though there are many such devices even in the theoretical disciplines. Thus the term 'phenomenology' expresses a maxim which can be formulated as 'To the things themselves!' It is opposed to all free-floating constructions and accidental findings; it is opposed to taking over any conceptions which only seem to have been demonstrated; it is opposed to those pseudo-questions which parade themselves as 'problems', often for generations at a time. Yet this maxim, one may rejoin, is abundantly self-evident, and it expresses, moreover, the underlying principle of any scientific knowledge whatsoever. Why should anything so self-evident be taken up explicitly in giving a title to a branch of research? In point of fact, the issue here is a kind of 'self-evidence' which we should like to bring closer to us, so far as it is important to do so in casting light upon the procedure of our treatise. We shall expound only the preliminary conception [Vorbegriff] of phenomenology. This expression has two components: "phenomenon" and "logos." Both of these go back to terms from the Greek: φαινόμενον and λόγος. Taken superficially, the term "phenomenology" is formed like "theology," "biology," "sociology"―names which may be translated as "science of God," "science of life," "science of society." This would make phenomenology the *science of phenomena*. We shall set forth the preliminary conception of phenomenology by characterizing what one has in mind in the term's two components, 'phenomenon' and 'logos', and by establishing the meaning of the name in which these are *put together*. The history of the word itself, which presumably arose in the Wolffian school, is here of no significance."―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, pp. 49-51
Human existence can relate to beings only if it holds itself out into the nothing. Going beyond beings occurs in the essence of Dasein. But this going beyond is metaphysics itself. This implies that metaphysics belongs to the "nature of man." It is neither a division of academic philosophy nor a field of arbitrary notions. Metaphysics is the basic occurrence of Dasein. It is Dasein itself. Because the truth of metaphysics dwells in this groundless ground it stands in closest proximity to the constantly lurking possibility of deepest error. For this reason no amount of scientific rigor attains to the seriousness of metaphysics. Philosophy can never be measured by the standard of the idea of science.If the question of the nothing unfolded here has actually questioned us, then we have not simply brought metaphysics before us in an extrinsic manner. Nor have we merely been "transposed" to it. We cannot be transposed there at all, because insofar as we exist we are always there already. "For by nature, my friend, man's mind dwells in philosophy" (Plato, Phaedrus, 279a). So long as man exists, philosophizing of some sort occurs. Philosophy―what we call philosophy―is metaphysics getting under way, in which philosophy comes to itself and to its explicit tasks. Philosophy gets under way only by a peculiar insertion of our own existence into the fundamental possibilities of Dasein as a whole. For this insertion it is of decisive importance, first, that we allow space for beings as a whole; second, that we release ourselves into the nothing, which is to say, that we liberate ourselves from those idols everyone has and to which he is wont to go cringing; and finally, that we let the sweep of our suspense take its full course, so that it swings back into the basic question of metaphysics which the nothing itself compels: 'Why are there beings at all, and why not rather nothing?"―from_What is Metaphysics?_
Metaphysics thinks about beings as beings. Wherever the question is asked what beings are, beings as such are in sight. Metaphysical representation owes this sight to the light of Being. The light itself, i.e., that which such thinking experiences as light, does not come within the range of metaphysical thinking; for metaphysics always represents beings only as beings. Within this perspective, metaphysical thinking does, of course, inquire into the being which is the source and originator of this light. But the light itself is considered sufficiently illuminated as soon as we recognize that we look through it whenever we look at beings.In whatever manner beings are interpreted―whether as spirit, after the fashion of spiritualism; or as becoming and life, or idea, will, substance, subject, or *energeia*; or as the eternal recurrence of the same events―every time, beings as beings appear in the light of Being. Wherever metaphysics represents beings, Being has entered into the light. Being has arrived in a state of unconcealedness (aletheia). But whether and how Being itself involves such unconcealedness, whether and how it manifests itself in, and as, metaphysics, remains obscure. Being in its revelatory essence, i.e., in its truth, is not recalled. Nevertheless, when metaphysics gives answers to its question concerning beings as such, metaphysics speaks out of the unnoticed revealedness of Being. The truth of Being may thus be called the ground in which metaphysics, as the root of the tree of philosophy, is kept and from which it is nourished.Because metaphysics inquires about beings as beings, it remains concerned with beings and does not devote itself to Being as Being. As the root of the tree, it sends all nourishment and all strength into the trunk and its branches. The root branches out in the soil to enable the tree to grow out of the ground and thus to leave it. The tree of philosophy grows out of the soil in which metaphysics is rooted. The ground is the element in which the root of the tree lives, but the growth of the tree is never able to absorb this soil in such a way that it disappears in the tree as part of the tree. Instead, the roots, down to the subtlest tendrils, lose themselves in the soil. The ground is ground for the roots, and in the ground the roots forget themselves for the sake of the tree...Metaphysics, insofar as it always represents only beings as beings, does not recall Being itself. Philosophy does not concentrate on its ground. It always leaves its ground―leaves it by means of metaphysics. And yet, it never escapes its ground...Insofar as a thinker sets out to experience the ground of metaphysics, insofar as the attempts to recall the truth of Being itself instead of merely representing beings as beings, his thinking has in a sense left metaphysics. From the point of view of metaphysics, such thinking goes back into the ground of metaphysics."―from_The Way Back to the Ground of Metaphysics_
Our conduct of the ontological investigation in the first and second parts opens up for us at the same time a view of the way in which these phenomenological investigations proceed. This raises the question of the character of method in ontology. Thus we come to the third part of the course: the scientific method of ontology and the idea of phenomenology. The method of ontology, that is, of philosophy in general, is distinguished by the fact that ontology has nothing in common with any method of any of the other sciences, all of which as positive sciences deal with beings. On the other hand, it is precisely the analysis of the truth-character of Being which shows that Being also is, as it were, based in a being, namely, in the Dasein. Being is given only if the understanding of Being, hence the Dasein, exists. This being accordingly lays claim to a distinctive priority in ontological inquiry. It makes itself manifest in all discussions of the basic problems of ontology and above all in the fundamental question of the meaning of Being in general. The elaboration of this question and its answer requires a general analytic of the Dasein. Ontology has for its fundamental discipline the analytic of the Dasein. This implies at the same time that ontology cannot be established in a purely ontological manner. Its possibility is referred back to a being, that is, to something ontical―the Dasein. Ontology has an ontical foundation, a fact which is manifest over and over again in the history of philosophy down to the present. For example, it is expressed as early as Aristotle's dictum that the first science, the science of Being, is theology. As the work of the freedom of the human Dasein, the possibilities and destinies of philosophy are bound up with man's existence, and thus with temporality and with historicality, and indeed in a more original sense than is any other science. Consequently, in clarifying the scientific character of ontology, *the first task is the demonstration of its ontical foundation* and the characterisation of this foundation itself."―from_The Basic Problems of Phenomenology_
Thus with the question of the Being of truth and the necessity of presupposing it, just as with the question of the essence of knowledge, an 'ideal subject' has generally been posited. The motive for this, whether explicit or tacit, lies in the requirement that philosophy should have the '*a priori*' as its theme, rather than 'empirical facts' as such. There is some justification for this requirement, though it still needs to be grounded ontologically. Yet is this requirement satisfied by positing an 'ideal subject'? Is not such a subject *a fanciful idealization*? With such a conception have we not missed precisely the *a priori* character of that merely 'factual' subject, Dasein? Is it not an attribute of the *a priori* character of the factical subject (that is, an attribute of Dasein's facticity) that it is in the truth and in untruth equiprimordially?The ideas of a 'pure "I"' and of a 'consciousness in general' are so far from including the *a priori* character of 'actual' subjectivity that the ontological characters of Dasein's facticity and its state of being are either passed over or not seen at all. Rejection of a 'consciousness in general' does not signify that the *a priori* is negated, any more than the positing of an idealized subject guarantees that Dasein has an *a priori* character grounded upon fact.Both the contention that there are 'eternal truths' and the jumbling together of Dasein's phenomenally grounded 'ideality' with an idealized absolute subject, belong to those residues of Christian theology within philosophical problematics which have not as yet been radically extruded.The Being of truth is connected primordially with Dasein. And only because Dasein is as constituted by disclosedness (that is, by understanding), can anything like Being be understood; only so is it possible to understand Being."―from_Being and Time_.

Certainly, what Kant calls the transcendental reference, experience and object of experience are in a sense present in both opposed views of the nature of the subjective *a-priori*. In both cases the object must 'order itself' according to the rules of the knowing mind or its functions, irrespective of whether the specific function of cognition is based on a systematic construction, synthetization, formation of the object from 'given' sensational material or on a methodical selection-process (suppression, abstraction, disregard) imposed on a self-constituting object. For if the order of selection in which the fulness of the world, as it is in ipseity, reaches man (or a particular kind of man, e.g., a type of racial or cultural unity) is so governed that an object of essence *B* is only given when an object of essence *A* has already been given (if, that is to say, *A* has datum-priority over *B* in order of time―not necessarily in direct succession), then if an object *X* is simultaneously of essence *A* and *B*, everything which is true of *A* must necessarily be true of *X*―not vice versa. For example, if spatiality and extensity have strict perceptual priority over all essential properties of matter and corporeality, geometry must be strictly valid for all possible bodies. But the same principle, the applicability of geometry to all bodies without exception, would still hold good if Kant's doctrine were true―though it denies the very reality of extension and space, and explains the spatial form as merely a subjective aspect of the datum. Thus in both cases the transcendental validity of the so-called *a-priori*, even for the objects of experience, would persist, so that in itself it offers us *no* criterion of choice between one or other *hypothesis*―that which supposes a synthetic addition of the form on the part of the spontaneous mind, or the other, which postulates an ordered selection in conformity with foreknown essences." ―from_On the Eternal in Man_.
