In general, Kantian philosophy is seen as an abstract theory that has almost no direct relation to everyday life and deals mainly with speculative problems. Unlike the prejudice that it would be difficult to find any advice on a series of difficult conflict situations in life, his philosophy contains concrete clues and arguments from which a philosophical counselor can get nourishment. Moreover, parallel to his academic research and teaching, Kant has, as it were, led the life of a philosophical practitioner. This study analyzes Kant’s writings, from which his doing philosophy (Philosophieren) can be re-organized. It also seeks to identify the resources that not only illuminate the identity problem of philosophical practice, but can also be applied to philosophical counseling. After clarifying the philosophy-practical goal of “philosophy according to the concept of the world”(II), it is understood how Kant dealt with the problem of so-called mental weaknesses or illnesses in his writings and lectures. Particular attention is paid to Kant s views on hypochondria(III). The final part of the thesis interprets the philosophical significance of the twin-track strategy of his philosophical activity―as an academic teacher and at the same time as a philosophical practitioner.
