This article is the second of a triad that is the dialogue, specifically the involvement, between the philosophy of Denis Diderot and the skepticism. The first article, entitled "The young Diderot and the skepticism of Thoughts", was published in the journal Dois Pontos, in its edition dedicated to the theme of skepticism (see PIVA, 2007), and limited itself to a detailed analysis of the problem of attitude sceptical on Thoughts on Philosophical, 1746. This article, in turn, examines two key issues, this time on The Tour of Sceptical or The Boulevards, 1747, the latest book in which the skepticism is raised to prominence by the encyclopaedist, two years before he was finally over atheist to materialism atheist: 1) the interpretation that Diderot develops of skepticism and 2) its position ahead of him. The third and final text of the triad review - of course, in a next opportunity - the presence of skepticism in thought by Diderot of maturity, namely the period commencing in 1749, with the drafting of the Letter on the Blind, where the issue of sceptical is certainly going to lose in his works that had relevance to the origin of their thoughts, including changing of registration.
