Abstract
Fichte was at the height of his philosophical activity and influence during the last decade of the eighteenth century in Jena. It was during this period that he developed his idea of a Wissenschaftslehre or a “science of knowledge.” A Wissenschaftslehre is an ongoing investigation by subjects of their subjectivity which may be captured only imperfectly in medias res in the form of a written document, but which is crucially not identical with any written philosophical text. So Fichte distinguishes between Wissenschaftslehre and its presentations. In the Jena period Fichte completed two such presentations. The first, the Grundlage der gesammten Wis-senschaftslehre [WL], contains the famous analysis of the preconditions for consciousness in terms of the posits of I and not-I and their reciprocal limitation. Fichte became dissatisfied with his treatment of the central problems in the 1794 version and began working on a second version in 1796. Only two introductions and the first chapter of this new presentation appeared in print. Due to his dawning belief that philosophy was appropriately done solely in oral or dialogic form and the psychic toll of the “atheism controversy” that led to his dismissal from Jena in 1799, by the early 1800's Fichte abandoned plans to publish the entire second presentation. Lectures on the entire second presentation given in 1796-9, the Wissenschaftslehre nova methodo [WLnm], are preserved, however, in two sets of student notes. The importance of the discovery of these notes is difficult to overestimate. WLnm develops new and more convincing positions on such fundamental issues as the nature of subjectivity, the unity of reason, and the relation between self-consciousness and intersubjectivity that greatly enhance Fichte's historical status and his relevance to contemporary debates on a variety of philosophical concerns.
