If I could forget you! Is my love then a work of memory? Even if time expunged everything from its tablets, expunged even memory itself, my relation to you would stay just as alive, you would still not be forgotten. If I could forget you! What then should I remember? For after all, I have forgotten myself in order to remember you: so if I forgot you I would come to remember myself; but the moment I remembered myself I would have to remember you again. If I could forget you! What would happen then? There is a picture from antiquity. It depicts Ariadne. She is leaping up from her couch and gazing anxiously after a ship that is hurrying away under full sail. By her side stands Cupid with unstrung bow and drying his eyes. Behind her stands a winged female figure in a helmet. It is usually assumed this is Nemesis. Imagine this picture, imagine it changed a little. Cupid is not weeping and his bow is not unstrung; or would you have become less beautiful, less victorious, if I had become mad? Cupid smiles and bends his bow. Nemesis does not stand inactive by your side; she too draws her bow. In that other picture we see a male figure on the ship, busily occupied. It is assumed it is Theseus. Not so in my picture. He stands on the stern, he looks back longingly, spreads his arms. He has repented, or rather, his madness has left him, but the ship carries him away. Cupid and Nemesis both aim at him, an arrow flies from each bow; their aim is true; one sees that, one understands, they have both hit the same place in his heart, a sign that his love was the Nemesis that wrought vengeance." ―Johannes de Silentio, from_Either/Or: A Fragment of Life_
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.
