This memoir documents the author's transition from mathematics to philosophy and their subsequent engagement with Rádl's concept of truth amidst the rising tide of Marxism. The narrative centers on a paper presented by the author in Professor Rieger’s seminar, which examined Masaryk’s concept of truth and its influence on the work of Kozák, Hromádka, and Rádl. The text vividly depicts the volatile academic environment of the time, where traditional philosophical inquiries met aggressive criticism from "new Marxist" students. Due to ideological opposition, the seminar presentation was halted before reaching its climax, leaving the final section on Rádl unwritten despite the author having gathered sufficient materials. Beyond the academic context, the text reflects on the author's strategic approach to early seminar participation as a means to navigate escalating requirements and political pressure. This account provides an insightful look into the intellectual struggles and ideological constraints of the Czechoslovak philosophical scene in the late 1940s, highlighting the profound impact of Rádl's thought on the author’s own philosophical development.
