On the nature of thinking without representation

This article focuses on Deleuze’s attempt to describe so-called thinking of differences, which severs any connection with the premises of natural pre-philosophical thinking and good will tending towards good and truth. The author believes that Deleuze’s thinking of differences does have a rather evident premise. For Deleuze, thinking is an energy flow or sensual “vitality”.Another approach to analysing the fundamentals of thinking can be found in Kant’s article “What Does It Mean to Orient Oneself in Thinking?” where he speaks of the “need of reason”. Since the “need of reason” is necessary for the practical interest of reason itself, it directs, according to Kant, not only practical reason, but also general systematic and critical thinking. It is “common sense”, as the location of this “need of reason”, that can and must be accepted as a valid and ra-tional premise for thinking.As a follower of the tradition of Kant’s transcendental philosophy, the founder of Marburg School of Neo-Kantianism, develops and deepens insight into the issue in question thus obtaining original and interesting results
