Following his appointment to a professorship in philosophy at the University of Erlangen, Fichte had to prepare lectures for the summer semester of 1805, including the Institutiones omnis philosophiae, which, like the Jena lectures on Logic and Metaphysic, were conceived as an introduction to the Wissenschaftslehre. Particularly interesting is the portion of this text devoted to elaborations of formal and higher (methodological) logic. For more advanced students, Fichte lectured on the Wissenschaftslehre. He wished this version to be understood as the fourth successive version of the Wissenschaftslehre, counting from the winter of 1804. In this Wissenschaftslehre Fichte presented his transcendental theory step by step, in a ongoing dialog with Schelling's Philosophie und Religion (1804), as the overcoming of speculative metaphysics.
