Kant had brought into use the term Deduction, and Fichte follows him. The term leads to some confusion: for in English, by its modern antithesis to induction, it suggests _a priori_ methods in all their iniquity. It means a kind of jugglery which brings an endless series out of one small term. Kant has explained that he uses it in the lawyer’s sense in which a claim is justified by being traced step by step back to some acknowledged and accepted right(50). It is a regressive method which shows us that if the original datum is to be accepted it carries along with it the legitimation of the consequence. This method Fichte applies to psychology. Begin, he says like Condillac, with the barest nucleus of soul-life; the mere sentiency, or feeling: the contact, as it were, with being, at a single point. But such a mere point is unthinkable. You find, as Mr. Spencer says, that “Thought” (or Consciousness) “cannot be framed out of one term only.” “Every sensation to be known as one must be perceived.” Such is the nature of the Ego—a subject which insists on each part being qualified by the whole and so transformed. As Mr. Spencer, again, puts it, the mind not merely tends to revive, to associate, to assimilate, to represent its own presentations, but it carries on this process infinitely and in ever higher multiples. Ideas as it were are growing in complexity by re-presenting: i.e. by embracing and enveloping elements which cannot be found existing in separation. In the mind there is no mere presentation, no bare sensation. Such a unit is a fiction or hypothesis we employ, like the atom, for purposes of explanation. The pure sensation therefore—which you admit because you must have something to begin with, not a mere nothing, but something so simple that it seems to stand out clear and indisputable—this pure sensation, when you think of it, forces you to go a good deal further. Even to be itself, it must be more than itself. It is like the pure or mere being of the logicians. Admit the simple sensation—and you have admitted everything which is required to make sensation a possible reality. But you do not—in the sense of vulgar logic—deduce what follows out of the beginning. From that, taken by itself, you will get only itself: mere being will give you only nothing, to the end of the chapter. But, as the phrase is, sensation is an element in a consciousness: it is, when you think of it, always more than you called it: there is a curious “continuity” about the phenomena, which makes real isolation impossible.
