The Master s Dissertation The democratic phenomenon in the dimension of opinion and its disfiguration analyzes the democratic phenomenon taking as a principle its representative character and giving special focus to its disfiguration processes, starting from the premise that democracy contains, in itself, the elements capable of figuring it and also of disfiguring it. This analysis was based on the theories on the researched subject, starting with the perspective of Joseph Schumpeter, whose theory has been hegemonic in political science for decades, passing through the criticisms made to the referred theory by Peter Bachrach and diving deeper into the thesis of Nadia Urbinati, which is considered to be an alternative and more accurate perspective to face the ongoing processes of democratic disfiguration in several countries. With Urbinati, the protagonist of the present dissertation, the dimensions of the sphere of opinion and will in the structuring of the democratic way of life are stressed, showing at what level and in what way certain deformities, that can arise during the metabolic flow of democratic life, are capable of disfiguring it.
