The present paper focuses on the development of Czech philosophical thought during the period of the First Republic. It is a time of remarkable diversity in this important part of spiritual culture. Many modern philosophical trends also developed during this time. Here we also encounter a change in the institutional security of theoretical and educational work (the creation of new universities, the publication of journals and monographs, and the organization of a world philosophical congress). This development had a discursive character. (...) The question of the social involvement of philosophy in new political conditions was raised. This concerns one aspect of the discourse on the role of theoretical thought (philosophy, ethics, science) in the development of a program of real humanity within the framework of a democratic society. The so-called “struggle for the freedom of Czech philosophy” represented an intergenerational conflict, reflecting the broader issue of interpreting Czech history and its meaning. This article thus attempts to provide a brief perspective on intellectual diversity as the outcome of this discourse. It illustrates, through a specific historical period, the view that, in Czech philosophy and ethics, many thinkers and ideas can be found which are so original that they may serve as a remarkable source of inspiration even for the present day.
