This record represents a continuation of a discussion on ethical issues, specifically focusing on the moral aspect of knowledge, encompassing the relationship between truth and freedom, following points 15-19 of the previous material. It then transitions to a new topic: the origin and nature of evil. The record references earlier discussions from the late 1950s concerning this subject, including articles by Jan Dus, J. S. Trojan, Petr Pokorný, and a reaction to Hejdánek in Křesťanská revue. It specifically delves into whether evil stems from ill will or has deeper roots, and also touches upon a debate on vegetarianism. It is discussed that philosophy cannot be based on feelings and moods, and considerations of decision-making motivations and determinism are explored. The record is divided into two cassettes and includes both exposition and discussion.
