This text is a preserved fragment of preparatory notes for a home seminar held in November 1980, focusing on philosophy's relationship with religion and the specific concept of "the fourth." The author examines the historical roots of philosophical thought and takes a critical stance toward the early philosophical treatment of myth. He points out that while the first philosophers superficially rejected myth and religion, the element of "the fourth" remained un-denied in their thinking. The text suggests the necessity of a new philosophical orientation toward the religious dimension and identifies fundamental flaws in traditional philosophical solutions to this issue. The mention of Heraclitus, although left unfinished, indicates the author's intent to analyze the ancient roots of the problem within the context of modern philosophical reflection. This fragment serves as a valuable record of intellectual life within the Czechoslovak dissident movement, where home seminars provided a space for independent inquiry into fundamental ontological and theological questions outside official academic structures.
