Krytyka konwencjonalizmu w myśli Leszka Kołakowskiego w pierwszej połowie lat pięćdziesiątych

This article aims to emphasize epistemological aspects of Leszek Kołakowski’s critique of the radical conventionalism of Kazimierz Ajdukiewicz, as well as his critique of the French representatives of the so-called new critique of sciences. These aspects presuppose or imply, implicitly or explicitly, a stance close to radical empiricism and oppose the views of Marx and Engels, although they harmonize with Lenin’s theory of reflection. Scholars rarely appreciate these aspects of Kołakowski’s early thought. They do so despite their potential role in the analysis of the evolution of his views towards a so-called revisionist stance. Kołakowski’s attitude to different variants of conventionalism and positivistic thought in general should be explored further, since he never abandoned his critique of these doctrines.
