Neo-Kantianism is traditionally seen as a philosophy that was formed to develop and actualise Kant’s philosophy and Kantian transcendental methodology. However, Kant was the determining, but by no means the only, influence on the emergence of the neo-Kantian tradition. Neo-Kantianism was strongly influenced by the entire German post-Kantian philosophy, especially by Fichte and Hegel, although neo-Kantians have repeatedly tried to dissociate themselves from the great idealists. In many ways neo-Kantianism was cultivated by the Fichtean reading of Kant, which enabled succeeding (...) philosophers, notably H.-G. Gadamer, to consider neo-Kantianism to be “hidden neo-Fichteanism”. The main goal of this study is a historical-philosophical reconstruction of the image of Fichtean philosophy formed within German neo-Kantianism. To achieve this aim I have analysed the key projects of the German neo-Kantians in which the influence of Fichte’s philosophy, in particular his interpretation of the Kantian doctrine of the primacy of practical reason, is most clearly manifested. I show that the theory of values of the Southwest neo-Kantians and the ethics of pure will of the Marburg neo-Kantians are associated with the Fichtean revision of Kant’s doctrine of the primacy of practical reason. The following, in my opinion, are the main features of the image of Fichte’s philosophy: it is close to neo-Kantians precisely because it strives to combine theoretical and practical reason; it is in ethics that Fiche’s ideas are most manifest in neo-Kantianism; neo-Kantian original theories contain the ideas of self-consciousness “in the spirit” of Fichte. The conclusion is drawn that the growth of the metaphysical component in neo-Kantian doctrines may be connected with the influence of Fichte’s philosophy. (shrink)
