 The final portion of the Jena system is devoted to “the philosophy of the postulates,” a discipline that Fichte conceived of as occupying the middle ground between purely theoretical and purely practical philosophy. In this portion of the system the world is considered neither as it simply is nor as it simply ought to be; instead, either the practical realm of freedom is viewed from the theoretical perspective of the natural world (in which case one considers the postulates that theoretical reason addresses to practical reason) or else, alternatively, the natural world is viewed from the perspective of practical reason or the moral law (in which case one considers the postulates that practical reason addresses to theoretical reason). The first of these perspectives is that of juridical philosophy or philosophy of law, or what Fichte calls the “doctrine of right” (Rechtslehre); the latter is that of the philosophy of religion.
