The subject matter of the article is the concept of “the real use of reason” alluded to by Kant in Critique of Pure Reason A299/b355 and in A305/b362. After comparing it with the “real use of understanding” examined in De mundi sensibilis and in the Critique of Pure Reason, the real use of reason is presented as a legitimate and useful performance that should be distinguished from the deceiving illusion induced by an appearance generated by reason itself. The real use (...) of reason proves itself as an unavoidable condition for the regulative use of ideas as well as a condition for the production of a critical metaphysics. (shrink)

Most scholars dealing with neo-Kantianism emphasize the existence of an explicit origin that characterizes neo-Kantianism as a clearly defined ‘movement’ with certain objects. In spite of the fact that differences between various neo-Kantian authors are mentioned in the current discourse (e. g. ‘Südwestdeutsche’ and ‘Marburger Schule’) scholars claim a singular unity of all neo-Kantian debates represented in the problem of ‘Geltung’. This is used to construct a certain relevance of neo-Kantianism in today’s philosophy. My contribution will pursue a historical approach (...) following Klaus Christian Köhnke’s and Ulrich Sieg’s demands. Instead of sketching systematic topics I pay further attention to the context in which an essence of neo-Kantianism was claimed or rejected. In doing so I will examine the discussions on the doctrine of postulates in Kant’s philosophy mainly led by Hans Vaihinger’s ‘Philosophy of As If’ and the impact of Eduard von Hartmann on the genesis of neo-Kantianism. I conclude that the definition of a consistent neo-Kantian ‘movement’ was an effect of rejecting spiritualist interpretations of the doctrine of postulates and in the following a rejection of the whole doctrine as ‘mysticism’ in canonical Kant interpretations.

Russian occupation of Königsberg during the Seven Years’ War had a great impact on the residents of East Prussia capital. That time significantly changed the cultural city life, i.e. there was a release from narrow-mindedness and prejudices of the Protestant city that was influenced by Pietism; social mores were liberalized; in comparison with pre-war time the university started playing a more significant part, and the status of university professors rose. All these changes positively affected Kant’s life and his philosophical formation. (...) Because of the occupation Kant remained in contact with Prussian, Austrian, and Russian officers for many years, and made friends with a number of merchants. This influenced his position regarding the war, history understanding, and his assessment of Frederick the Great’s role and significance. (shrink)
