The aim of this article is (a) an Introduction to F. de Monbron’s, Le Cosmopolite in order to present a different way of understanding Cosmopolitism in XVIIIth. (b) Such way doesn't think that humankind has the same background and identical rights, rather humanity is something you get travelling, looking at the different and realizing you are a tiny, insignificant thing. (c) So little thing that you have not a firm identity. With this idea I think we can separate cosmopolitism from globalization and become a “citizen of the world” because we have curiosity to know the multiform and varied world we live in.
