 Following the completion of these projects, Fichte devoted his time in Zurich to rethinking and revising his own philosophical position. While maintaining his allegiance to the new Critical or Kantian philosophy, Fichte was powerfully impressed by the efforts of K. L. Reinhold to provide the Critical philosophy with a new, more secure “foundation” and to base the entire system upon a single “first principle.” At the same time, he became acquainted with the works of two authors who were engaged in skeptical attacks upon the philosophies of both Kant and Reinhold: Solomon Maimon and G. E. Schulze (“Aenesidemus”). It was the need to respond to the sharp criticisms of these authors that eventually led Fichte to construct his own, unique version of transcendental idealism, for which, in the spring of 1794, he eventually coined the name Wissenschaftslehre (“Doctrine of Science” or “Theory of Scientific Knowledge”). During the winter of 1793/94 he composed a long manuscript, “Private Mediations on Elementary Philosophy/Pracical Philosophy,” in which worked out some of the fundamental features of his new system. In Feburary and March of 1794 he gave a series of private lectures on his conception of philosophy before a small circle of influential clerics and intellectuals in Zurich.
