This essay approaches the period prior to the works considered as the different versions of the Doctrine of Science, by J. G. Fichte, and aims not only at discerning the origin of the need for a principle of identity, but also at retracing the first steps of the whole problem of the possibility of an absolute principle of all philosophy. The focus shall be the «Aenesidemus-Rezension», where Fichte joins his voice to the heated argument previously struck by K. L. Reinhold and G. E. Schulze, and, urged to rethink Reinhold's principle of consciousness and the criticism raised by Schulze, is brought to believe the necessity for a new absolute principle; but where, and this is the fundamental idea of this essay, Fichte realizes the philosophical insufficiency of Reinhold's system as a language-related insufficiency, and therefore the whole problem as one intimately dependent on a linguistic apodicticity, and moves on to propose a new national terminology, a systematically certain and unequivocal philosophical language, which might meet the demands of a philosophical system ruled by an absolute principle – a problem which would soon be in the agenda of a whole generation of young idealists around the Professor of Jena.
