Abstract:
The article focuses on understanding some of the self-evident premises of the philosophy of the 17th–19th centuries that make up the horizon of the Enlightenment. One of these premises is Immanuel Kant’s idea of independent thinking. Based on the analy-sis of the polemics of Kant and Friedrich Heinrich Jacobi about the “extrasensible abili-ties” of the reason, the question is raised about the possibility of understanding someone else’s concept based on other existential preferences. Answering this question, we dis-tinguish between the concept of the Enlightenment and the practical principle of the Enlightenment and show that the supporter of the ideology of the Enlightenment (Kant) and his critic (Jacobi) appear in the light of the principle of independent thinking as the spokesmen of the spirit, not the letter of the Enlightenment. A condition for understanding someone else’s concept is a productive misunderstanding, which is one of the as-pects of the principle of independent thinking: the acceptance of the self-evident as incomprehensible, the shift of one’s attention to one’s own how-being and the percep-tion of thought as a gift.
