The subject of the study is, in general - the Aristotle's judicial rhetoric and in detail - 'logos' of this rhetoric (the methodology of judicial persuasion). The Aristotle's works are sources: 'The Art of Rhetoric', 'The Rhetoric to Alexander', 'Topics', 'Prior Analytics', 'Posterior Analytics' as well as thesis 'On Sophistical Refutations'. The preliminary remarks include the Aristotle's opinions of reasons, motives, guilt and qualifications of crimes. The 'logos' is presented with explanations of syllogism (demonstrative, dialectical, rhetorical, eristic) and induction (dialectical, rhetorical) as well as Aristotle's exposition of the theories of 'enthymemes' and 'topoi' in the judicial rhetoric. The discussion of unrhetorical means of judicial persuasion was added as a supplement. Two aims were realized in the work: a synthetic formulation of the Aristotle's conception of 'logos' in the judicial rhetoric and the logical interpretation of the most important method of rhetoric - the means of 'topos'.
