This book, assuming as truthful the rather common assessment in the work criticizing democracy of the need for optimization thereof, does not intend to enter the realms of discussion of the advantages that verify that. Nor does it intend to discuss the advantages of this form of exercise of power over other regimes which might be a prerogative of Political Science. The existence of democracy and its glorification as a postulate are sometimes seen as an obvious phenomena. However if democracy is a natural system that is expected to be found in the political environment, why then this “strange” sensation when, for example, we find ourselves face to face with Lincoln’s historical phrase that concisely defined it as “a government of the people, by the people, for the people”? The considerations on each of the assurances contained therein certainly give rise to a great deal of questioning, if not contradictions in our cores. It is exactly at this point that a series of authors, producing a great deal of work along the past few years, supports the adoption of the so-called “deliberative democracy”.
