 Having established the foundation of his new system, Fichte then turned to the task of constructing upon this foundation a fully-articulated transcendental system, the overall structure of which is most clearly outlined in the concluding section of the transcripts of his lectures on Wissenschaftslehre nova methodo. According to this plan, which has no analog in Fichte’s later writings, the Entire Wissenschaftslehre is to consisting of four, systematically interrelated parts:: (1) first philosophy, which corresponds to the “foundational” portion of the system, as presented in the Foundation of the entire Wissenschaftslehre and revised in the lectures on Wissenschaftslehre nova methodo; (2) “theoretical philosophy” or “philosophy of nature,” (3) “practical philosophy” or ethics (corresponding to the content of the System of Ethics); and (4) “philosophy of the postulates,” which includes the subdisciplines of “natural law” or “theory of right” (as expounded in the Foundation of Natural Right) and philosophy of religion.
