Epistemology Quotes

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_. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 124-128

Immanuel Kant

It is true, no doubt, that this principle of the necessary unity of apperception is itself an identical and therefore an analytic proposition; but it shows, nevertheless, the necessity of a synthesis of the manifold given in an intuition, a synthesis without which it would be impossible to think the thoroughgoing identity of self-consciousness. For through the *I*, as a simple representation, nothing manifold is given; only in intuition, which is distinct from this representation, can a manifold be given, and then, through *combination*, be thought in one consciousness. An understanding in which through self-consciousness all the manifold would be given at the same time would be one that *intuits*; our understanding can do nothing but *think*, and must seek intuition in the senses. I am conscious, therefore, of the identical self with respect to the manifold of the representations that are given to me in an intuition, because I call them one and all *my* representations, as constituting *one* intuition. This means that I am conscious *a priori* of a necessary synthesis of them, which is called the original synthetic unity of apperception, and under which all representations given to me must stand, but under which they must also be brought by means of a synthesis.”—from_Critique of Pure Reason_. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 128-129

Immanuel Kant

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

Arthur Schopenhauer

Philosophy is about everything when I say everything I mean both something and nothing. Something is what we can perceive and nothing is beyond our senses.

Mark D. Ekperi

He was pinched perspinngly in the epistemological dilemma of the skeptic, unable to accept solutions to problems he was unwilling to dismiss as unsolvable. He was never without misery, and never without hope.

Joseph Heller

Although some of her passages seek to persuade the reader of the meaninglessness and marginalization of the mathematics, Hayles is content to use mathematics as a means for understanding Borges, perhaps in the same way a sponge riddled with holes is useful in sopping up fluid reality.

Bloch William Goldbloom

Is numerical equality (forced by the use of specific physical units) the same as conceptual equality? Of course NOT!

Felix Alba-Juez

If proof were the standard of truth, fallacies would constitute the ultimate reality.

Raheel Farooq

Show me slowly what I onlyknow the limits ofDance me to the end of love

Leonard Cohen

On the other hand, when we disown our beliefs, we lose touch with ourselves. We no longer know who we are or what we believe and neither does anyone else.

Patty Houser

Nothing is as powerful as one's beliefs.

Patty Houser

Every novel says to the reader: “Things are not as simple as you think.” That is the novel’s eternal truth, but it grows steadily harder to hear amid the din of easy, quick answers that come faster than the question and block it off. In the spirit of our time, it’s either Anna or Karenin who is right, and the ancient wisdom of Cervantes, telling us about the difficulty of knowing and the elusiveness of truth, seems cumbersome and useless.

Milan Kundera

A great truth wants to be criticized not idolized

Friedrich Nietzsche

Irony is about contradictions that do not resolve into larger wholes, even dialectically, about the tension of holding incompatible things together because both or all are necessary and true. Irony is about humour and serious play. It is also a rhetorical strategy and a political method, one I would like to see more honoured within socialist-feminism.

Donna J. Haraway

We look not at the things which are what you would call seen, but at the things which are not seen. For the things which are seen are temporal. But the things that are not seen are eternal.

Madeleine L'Engle

Knowledge is not discovery, but recognition.

Raheel Farooq

Logic is the science not of external forms of thought, but of the laws of development "of all material, natural and spiritual things", i.e., of the development of the entire concrete content of the world and of its cognition, i.e., the sum-total, the conclusion of the History of knowledge of the world.

Vladimir Lenin

Metagapism is the belief that love is the ultimate reality, literally god and the one shared soul, and the source, nature and destiny of all.

John K. Brown

A prepared mind is always made up; it knows what it thinks and why it thinks that. When it's time to change, it just makes itself up a different way. A really made-up mind--made up properly, knowing what it knows and on what basis it knows it--is open. People close an undecided mind because they're trying to protect those sore uncertainties from getting bumped and scraped.

John Barnese

Pure analysis puts at our disposal a multitude of procedures whose infallibility it guarantees; it opens to us a thousand different ways on which we can embark in all confidence; we are assured of meeting there no obstacles; but of all these ways, which will lead us most promptly to our goal? Who shall tell us which to choose? We need a faculty which makes us see the end from afar, and intuition is this faculty. It is necessary to the explorer for choosing his route; it is not less so to the one following his trail who wants to know why he chose it.

Henri Poincaré

…every feeling is the perception of a truth...

Gottfried Wilhelm Leibniz

The mind leans on [innate] principles every moment, but it does not come so easily to distinguish them and to represent them distinctly and separately, because that demands great attention to its acts, and the majority of people, little accustomed to think, has little of it.

Gottfried Wilhelm Leibniz

The mind is not only capable of knowing [innate ideas], but further of finding them in itself; and if it had only the simple capacity to receive knowledge…it would not be the source of necessary truths…

Gottfried Wilhelm Leibniz

For the [innate] general principles enter into our thoughts, of which they form the soul and the connection. They are as necessary thereto as the muscles and sinews are for walking, although we do not at all think of them.

Gottfried Wilhelm Leibniz

Truth is, something exists, and everything exists for a reason. Regardless if the reason is known or unknown, knowable or unknowable, reason exists and can be named.

John K. Brown

The principle chore of brains is to get the body parts where they should be in order that the organism may survive. Improvements in sensorimotor control confer an evolutionary advantage: a fancier style of representing [the world] is advantageous so long as it... enhances an organism's chances for survival. Truth, whatever that is, takes the hindmost.

Patricia Churchland

But then with me the horrid doubt always arises whether the convictions of man's mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy.

Charles Darwin

The Bible is clear: Truth exists. It can be known. And when we ground our beliefs in it, we are rational.

Patty Houser

I should go so far as to say that embedded in the surrealistic frame of a television news show is a theory of anticommunication, featuring a type of discourse that abandons logic, reason, sequence and rules of contradiction. In aesthetics, I believe the name given to this theory is Dadaism; in philosophy, nihilism; in psychiatry, schizophrenia. In the parlance of the theater, it is known as vaudeville.

Neil Postman

ideas generate action when they are believed regardless of whether they are true or not in our opinion

Patricia Crone

But, though all our knowledge begins with experience, it by no means follows that all arises out of experience.

Immanuel Kant

Why should things be easy to understand?

Thomas Pynchon

True, the initial ideas are in general those of an individual, but the establishment of the reality and truth is in general the work of more than one person.

Willard F. Libby

Time is different for a tree than for a man. Sun and soil and water, these are the things a weirwood understands, not days and years and centuries. For men, time is a river. We are trapped in its flow, hurtling from past to present, always in the same direction. The lives of trees are different. They root and grow and die in one place, and that river does not move them. The oak is the acorn, the acorn is the oak.

George R.R. Martin

That is what we are, what we do: nose a net, push push, a net that never exists. The knots in the mesh as strong as our own believing. Our own fears.

Peter Heller

As an empiricist I continue to think of the conceptual scheme of science as a tool, ultimately, for predicting future experience in the light of past experience. Physical objects are conceptually imported into the situation as convenient intermediaries-not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer. For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing the physical objects and the gods differ only in degree and not in kind. Both sorts of entities enter our conception only as cultural posits. The myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience.

Willard Van Orman Quine

The desire to understand is almost synonymous with the desire to simplify, and it is closely bound up with the desire for certainty - for assurance. But, when we find we have over-simplified, this does not necessarily imply that our conclusions are wrong. It implies merely that they are less right than we thought, or that we have exaggerated their comprehensiveness.

Rupert Crawshay-Williams

It must be recognized that in any culture the source of law is the god of that society.

Rousas John Rushdoony

difference, distance, absence and seperation lie 'at the heart' of meaning, being and reality

Maggie MacLure

Ye cannot know eternal reality by a definition.

C.S. Lewis

People who have cut their teeth on philosophical problems of rationality, knowledge, perception, free will and other minds are well placed to think better about problems of evidence, decision making, responsibility and ethics that life throws up.

Simon Blackburn

Plato said that we are trapped inside a cave and know the world only through the shadows it casts on the wall. The skull is our cave, and mental representations are the shadows.

Steven Pinker

Explanation is where the mind rests.

David Hume

He who has a true idea simultaneously knows that he has a true idea, and cannot doubt of the truth of the thing perceived.

Baruch Spinoza

The order and connection of ideas in the same as the order and connection of things

Baruch Spinoza

How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there no more valuable work in his specialty? I hear many of my colleagues saying, and I sense it from many more, that they feel this way. I cannot share this sentiment. When I think about the ablest students whom I have encountered in my teaching, that is, those who distinguish themselves by their independence of judgment and not merely their quick-wittedness, I can affirm that they had a vigorous interest in epistemology. They happily began discussions about the goals and methods of science, and they showed unequivocally, through their tenacity in defending their views, that the subject seemed important to them. Indeed, one should not be surprised at this.

Albert Einstein

Sadly, because of our tribal brains, science carries a hefty cost. Treasured ideas that are loved by the community may be left behind, unable to compete with conflicting observations. Admired heroes may be found to have been mistaken. Years of hard work can amount to nothing thanks to a single observation, making a lifetime of effort seem like a waste of time. For our tribal brain, the philosopher’s toolbox is full of double-edged knives, capable of cutting away our hopes with the myths.

Mike McRae

The idea of a method that contains firm, unchanging, and absolutely binding principles for conducting the business of science meets considerable difficulty when confronted with the results of historical research. We find, then, that there is not a single rule, however plausible, and however firmly grounded in epistemology, that is not violated at some time or other. It becomes evident that such violations are not accidental events, they are not results of insufficient knowledge or of inattention which might have been avoided. On the contrary, we see that they are necessary for progress. Indeed, one of the most striking features of recent discussions in the history and philosophy of science is the realization that events and developments, such as the invention of atomism in antiquity, the Copernican Revolution, the rise of modern atomism (kinetic theory; dispersion theory; stereochemistry; quantum theory), the gradual emergence of the wave theory of light, occurred only because some thinkers either decided not to be bound be certain 'obvious' methodological rules, or because they unwittingly broke them.

Paul Karl Feyerabend

In the first case it emerges that the evidence that might refute a theory can often be unearthed only with the help of an incompatible alternative: the advice (which goes back to Newton and which is still popular today) to use alternatives only when refutations have already discredited the orthodox theory puts the cart before the horse. Also, some of the most important formal properties of a theory are found by contrast, and not by analysis. A scientist who wishes to maximize the empirical content of the views he holds and who wants to understand them as clearly as he possibly can must therefore introduce other views; that is, he must adopt a pluralistic methodology. He must compare ideas with other ideas rather than with 'experience' and he must try to improve rather than discard the views that have failed in the competition. Proceeding in this way he will retain the theories of man and cosmos that are found in Genesis, or in the Pimander, he will elaborate them and use them to measure the success of evolution and other 'modern' views. He may then discover that the theory of evolution is not as good as is generally assumed and that it must be supplemented, or entirely replaced, by an improved version of Genesis. Knowledge so conceived is not a series of self-consistent theories that converges towards an ideal view; it is not a gradual approach to truth. It is rather an ever increasing ocean of mutually incompatible alternatives, each single theory, each fairy-tale, each myth that is part of the collection forcing the others in greater articulation and all of them contributing, via this process of competition, to the development of our consciousness. Nothing is ever settled, no view can ever be omitted from a comprehensive account. Plutarch or Diogenes Laertius, and not Dirac or von Neumann, are the models for presenting a knowledge of this kind in which the history of a science becomes an inseparable part of the science itself - it is essential for its further development as well as for giving content to the theories it contains at any particular moment. Experts and laymen, professionals and dilettani, truth-freaks and liars - they all are invited to participate in the contest and to make their contribution to the enrichment of our culture. The task of the scientist, however, is no longer 'to search for the truth', or 'to praise god', or 'to synthesize observations', or 'to improve predictions'. These are but side effects of an activity to which his attention is now mainly directed and which is 'to make the weaker case the stronger' as the sophists said, and thereby to sustain the motion of the whole.

Paul Karl Feyerabend

The objection that science is self-correcting and thus needs no outside interference overlooks, first, that every enterprise is self-correcting (look at what happened to the Catholic Church after Vatican II) and, secondly, that in a democracy the self-correction of the whole which tries to achieve more humane ways of living overrules the self-correction of the parts which has a more narrow aim -- unless the parts are given temporary independence. Hence in a democracy local populations not only will, but also should, use the sciences in ways most suitable to them. The objection that citizens do not have the expertise to judge scientific matters overlooks that important problems often lie across the boundaries of various sciences so that scientists within these sciences don't have the needed expertise either. Moreover, doubtful cases always produce experts for the one side, experts for the other side, and experts in between. But the competence of the general public could be vastly improved by an education that exposes expert fallibility instead of acting as if it did not exist. (Chapter 19)

Paul Karl Feyerabend

Thought and science are therefore raising problems which their terms of study can never answer, many of which are doubtless problems only for thought. The trisection of an angle is similarly an insoluble problem only for compass and straight-edge construction, and Achilles cannot overtake the tortoise so long as their progress is considered piecemeal, endlessly having the distance between them. However, as it is not Achilles but the method of measurement which fails to catch up with the tortoise, so it is not man but his method of thought which fails to find fulfillment in experience.

Alan W. Watts

Scientists study only those aspects of the universe that it is within their gift to study: what is observable; what is measurable and amenable to statistical analysis; and, indeed, what they can afford to study within the means and time available. Science thus emerges as a giant tautology, a "closed system". It can present us with robust answers only because its practitioners take very great care to tailor the questions.

Colin Tudge

One of the advantages of science is that one's work, ultimately, is either replicated or it is not.
