is totally unable to comprehend works like Fichte's "Science of Knowledge," the "Metaphysics" of Aristotle, or Hegel's "Phenomenology." No science suffers so much as Philosophy from this false popular opinion, which understands neither itself nor its authority. The youth must _learn how to learn to understand_, and, in order to do this, he must know that one cannot immediately understand everything in its finest subdivisions, and that on this account he must have patience, and must resolve to read over and over again, and to think over what he has read.—— § 98. (3) Imagination returns again within itself to perception in that it replaces, for conceptions, perceptions themselves, which are to remind it of the previous conception. These perceptions may resemble in some way the perception which lies at the basis of the conception, and be thus more or less symbolical; or they may be merely arbitrary creations of the creative imagination, and are in this case pure signs. In common speech and writing, we call the free retaining of these perceptions created by imagination, and the recalling of the conceptions denoted by them, _Memory_. It is by no means a particular faculty of the mind, which is again subdivided into memory of persons, names, numbers, &c. As to its form, memory is the stage of the dissolution of conception; but as to its content, it arises from the interest which we take in a subject-matter. From this interest results, moreover, careful attention, and from this latter, facility in the reproductive imagination. If these acts have preceded, the fixing of a name, or of a number, in which the content interesting us is as it were summed up, is not difficult. When interest and attention animate us, it seems as if we did not need to be at all troubled about remembering anything. All the so-called mnemonic helps only serve to make more difficult the act of memory. This act is in itself a double function, consisting of, first, the fixing of the sign, and second, the fixing of the conception subsumed under it. Since the mnemonic technique adds to these one more conception, through whose means the things with which we have to deal are to be fixed in order to be able freely to express them in us, it trebles the functions of remembering, and forgets that the mediation of these and their relation——wholly arbitrary and highly artificial——must also be remembered. The true help of memory consists in not helping it at all, but in simply taking up the object into the ideal regions of the mind by the force of the infinite self-determination which mind possesses.
