VI. Epistemology Free of Assumptions and Fichte’s Principles of Science

Building on Kant's synthesis of “transcendental apperception”, Fichte found that all activity of the ego consisted in the assembly of the material of experience according to the forms of judgment. Judging consists in linking the predicate with the subject, which is expressed in a purely formal way by the sentence “a” = “a”. This proposition would be impossible if the unknown factor “x” that connects the first and second “a” were not based on an absolute ability to posit. Because the sentence does not mean: “a” is, but rather: if “a” is, then “a” is. There can be no question of postulating “a” absolutely. There is nothing left to arrive at something totally valid, other than to declare the positing itself to be absolute. While the “a” is conditional, the positing of the “a” is unconditional. But this setting is an act of the ego. The ego therefore can posit absolutely and unconditionally. In the sentence “a” = “a”, one “a” is only posited by presupposing the other; namely it is set by the ego. Fichte states, “If ‘a’ is posited in the ego, then it is posited.”[^8] This connection is only possible under the condition that there is something in the ego that is always the same, something that moves from one “a” to the other. And the “x” mentioned above is based on this constant. The ego that posits one “a” is the same as that which posits the other. And that means “I” “I” This sentence expressed in the form of the proposition: “If I am, then so it is”, but this proposition has no meaning. The ego is not placed under the presupposition of another, but rather it presupposes itself. But that means it is absolute and unconditional.
