In this article, I will focus on two lines of discussion: the first is the rise of post-secularist discourses and theories; the second is the frequent (and recent) attenuation of John Dewey's naturalism. If it is important for me to note the curious weakening of his naturalism among many contemporary pragmatists, it is in order to better respond to the theories of the "post-secular society". By returning to many of Dewey's texts, too often omitted from the discussion for the sole (...) benefit of A Common Faith, I will show that they provide a powerful antidote to contemporary post-secularism, by not ceding on the affirmation of a strong anti-surnaturalism, a guarantee of the realization of the democratic ideal and of the "scientific attitude" promoted by Dewey.
