The I posits this situation for itself. To posit does not mean to 'create' the objects of consciousness. The principle in question simply states that the essence of an I lies in the assertion of self-identity, i.e., that consciousness presupposes self-consciousness. Such immediate self-identity cannot be understood as a psychological fact, or an act or accident of some previously existing substance or being. It is an action of the I, but one that is identical with the very existence of this same I. In Fichte's technical terminology, the original unity of self-consciousness is an action and the product of the same I, as a "fact and/or act" ("Thathandlung"; Modern German: "Tathandlung"), a unity that is presupposed by and contained within every fact and every act of empirical consciousness, although it never appears as such.
