Abstract
The paper is concerned with the role of the logos in the sophistic thought. The author argues that the importance of logos is a result of the conviction that according to the Sophists human reality is somehow „created” through words in the process of constant communication and interpretation. This idea inspires the Sophists to research on the particular conditions of the process of persuasion and to analyze the factors which determine the persuasive power of speech. This interest in the power of "logos" leads the Sophists such as Protagoras, Gorgias, Antiphon to develop the techniques which aim at increasing the persuasive power of speech by addressing both rational and emotional part of the soul.
