Abstract: The subject of this research is important rhetorical features of the extract from Fedor Dostoevsky's 'The Borthers Karamazov'. This extract is known as the 'rebellion' of Ivan Karamazov and represents one the novel's central monologues in the form of argumentation. Tkachenko successively analyzes the structure of thesis, specifics of argumentation and purpose of the character's speech. The results of the analysis demonstrate the mechanisms of influence on other characters and the readers of the novel. Analysis of components of argumentation also shows that Ivan's speech has a rhetorical power and the speech itself is of manipulation nature: the hero uses numerous tricks that ensure credibility of his ideas while argumentation lacks a logical structure. In his research Tkachenko uses methods of rhetoric poetics that imply analysis of a literary text as the text that has an influence on the reader as well as study of artistic potential of traditional rhetoric forms found in the text. The scientific novelty of the research is caused by the fact that Ivan's speech is important for studies of a polyphonic novel and analysis of the phenomenon of independency of voices and ideas created by Fedor Dostoevsky.
