Abstract
As a continuation of our studies regarding the use of rhetoric in the thought of Thomas Hobbes, the present study deals with the relation between eloquence, passions and rebellion in The Elements of Law, Natural and Politic. Thus, it is explained how the leaders of sedition and rebellion are necessarily, according to Hobbes, “eloquent men”. The aim is not only to separate the rhetorical tradition from the foundation of political sciences, but also to point out the supposed damages caused by orators in civil life. Therefore, the conflicting and often contradictory relation between demonstration and persuasion in the politics of the 17th century is questioned, as well as the binding and constitutive role of passions.
