- The aim of this essay is to examine the theory of secularisation process developed by Charles Taylor in his work, "A Secular Age". With this work an ambitious project is pursued: to offer a new point of view by which to construct a different image of secularisation. Taylor wants to understand the new socio-cultural conditions in which the moral and spiritual search of believers and non-believers develops. The process of modernisation of Western societies, in fact, has not only produced conceptions that are hostile to religion (jacobinism, marxism, anarchism) and conditions which have often made many of the old religious practices impossible, but have also led to creative adaptations of religious experience to the changed sociological conditions. The history of secularisation therefore demonstrates the "improbability" that autonomous religious aspiration has disappeared. Even in the framework of a secular society, religion represents an "anthropological universal". Taylor's theory of secularisation presents a notable affinity with all those theories which refute any form of sociological or biological reductionism, assuming the original nature of the religious phenomenon.Keywords: exclusive humanism, secularization, neutralization, religion, modernity
