Abstract
The aim of this paper is to show the main thesis concerning the theory of cognition of the eminent neo-Kantian Heinrich Rickert, as presented in his work “Der Gegenstand der Erkenntnis”. On the one hand, Rickert finds out that thinking is fated to “clash with nothingness”, thus creating a temptation to reject all rigours and to yield to complete discretion. On the other hand, he attributes axiological status to nothingness which subjects thinking to a particular kind of “ought”. In his view, the cognizing subject is faced with an axiological choice: either discretion or truth and argues that it is worth opting for truth. His argumentation could be an interesting point of reference for contemporary culture gradually moving away from the type of thinking rooted in objectively existing principles.
