showed he meant by it something which is never derived from the senses, but which far transcends even the conceptions of the understanding, (with which Aristotle occupied himself,) inasmuch as in experience nothing perfectly corresponding to them could be found. Ideas are, according to him, archetypes of things themselves, and not merely keys to possible experiences; like the categories. In his view they flow from the highest reason, by which they have been imparted to human reason, which, however, exists no longer in its original state, but is obliged with great labour to recal by reminiscence—which is called philosophy—the old but now sadly obscured ideas. I will not here enter upon any literary investigation of the sense which this sublime philosopher attached to this expression. I shall content myself with remarking that it is nothing unusual, in common conversation as well as in written works, by comparing the thoughts which an author has delivered upon a subject, to understand him better than he understood himself,—inasmuch as he may not have sufficiently determined his conception, and thus have sometimes spoken, nay even thought, in opposition to his own opinions.
Plato perceived very clearly that our faculty of cognition has the feeling of a much higher vocation than that of merely spelling out phænomena according to synthetical unity, for the purpose of being able to read them as experience, and that our reason naturally raises itself to cognitions far too elevated to admit of the possibility of an object given by experience corresponding to them—cognitions which are nevertheless real, and are not mere phantoms of the brain.
This philosopher found his ideas especially in all that is practical,[1] that is, which rests upon freedom, which in its turn ranks under cognitions that are the peculiar product of reason. He who would derive from experience the con-
- ↑ He certainly extended the application of his conception to speculative cognitions also, provided they were given pure and completely à priori, nay, even to mathematics, although this science cannot possess an object otherwhere than in possible experience. I cannot follow him in this, and as little can I follow him in his mystical deduction of these ideas, or in his hypostatization of them: although, in truth, the elevated and exaggerated language which he employed in describing them is quite capablé of an interpretation more subdued and more in accordance with fact and the nature of things.
