The discussion of human nature in the 5th and 4th centuries BCE in the so-called sophistic movement

The paper discusses the debate on the human nature in the sophistic thought. Focusing on the "nature-culture" controversy it presents the evolution of the views of the sophists: from Protagoras' optimistic contention of the progress of mankind and his appraisal of culture to its criticism and the radical turn to nature in Antiphon, Hippias, Trasymachos, and Callicles. The paper aims at presenting the analysis of the ongoing discussion, with the stress laid on reconstruction of the arguments and concepts as well as the attitudes that are associated with various positions of this debate.
