This paper is built upon the theoretical framework of the Aristotelian Rhetoric and of the contemporary Deep Rhetoric. In particular, it considers the conceptual duo of logos and polis. The paper describes some epistemological, technical and anthropological features of rhetoric. Furthermore, it explains some critical issues in the contemporary debate, especially those related to the notion of fallacy. The paper specifically refers to the aim and the subject of rhetoric, on the relation between emotions and judgements and on the role of both speaker and audience.
