postulate, must really be performed by the "Ego." This may be seen, e.g., from the following passage. "The Theory of Science, then, arises, as itself a systematic discipline, just as do all possible sciences in so far as they are systematic, through a certain act of freedom, the determinate function of which is, more particularly, to make us conscious of the characteristic activity of intelligence as such. The result of this free act is that the necessary activity of intelligence, which in itself already is form, is further taken up as matter into a fresh form of cognition or consciousness." [50] What does Fichte here mean by the activity of the "intelligence," when we translate what he has obscurely felt into clear concepts? Nothing but the realisation of the idea of knowledge, taking place in consciousness. Had this been perfectly clear to Fichte, he ought to have expressed his view simply by saying, "It is the task of the Theory of Science to bring cognition, in so far as it is still an unreflective activity of the 'Ego,' into reflective consciousness; it has to show that the realisation of the idea of cognition in actual fact is a necessary activity of the 'Ego.'" Fichte tries to determine the activity of the "Ego." He declares "that the being, the essence of which consists solely in this that it posits itself as existing, is the Ego as absolute subject." [51] This positing of the Ego is for Fichte the original, unconditioned act "which lies at the basis of all the rest of consciousness." [52] It follows that the Ego, in Fichte's sense, can likewise begin all its activity only through an absolute fiat of the will. But, it is impossible for Fichte to supply any sort of content for this activity which his "Ego" absolutely posits. For, Fichte can name nothing upon which this activity might direct itself, or by which it might be determined. His Ego is supposed to perform an act. Yes, but what is it to do? Fichte failed to define the concept of cognition which the Ego is to realise, and, in consequence, he struggled in vain to find any way of advancing from his absolute act to the detailed determinations of the Ego. Nay, in the end he declares that the inquiry into the manner of this advance lies outside the scope of his theory. In his deduction of the idea of cognition he starts neither from an absolute act of the Ego, nor from one of the Non-Ego, but from a state of being determined which is, at the same time, an act of determining. His reason for this is that nothing else either is, or can be, immediately contained in consciousness. His theory leaves it wholly vague what determines, in turn, this determination. And it is this vagueness which drives us on beyond Fichte's theory into the practical part of the Wissenschaftslehre. [53] But, by this turn Fichte destroys all knowledge whatsoever. For, the practical activity of the Ego belongs to quite a different sphere. The postulate which we have
