ABSTRACT: The concept of secularism can be understood in a political perspective or in a legal one. However, secularism is frequently identified with the concept of neutrality, so committing an epistemological error. In this essay, I try to demonstrate that the religious logos is indistinguishable from secular reason, and they both have the same dignity in the public debate. Finally, the article seeks to demonstrate that secularism in pluralistic societies, requires the cooperative research of the values inherent in social practices, in a perspective that is neither relativistic nor ideological.
