Compared to the notable presence of Catholics in post-war political and cultural life, a great absence is noticeable today. In part, this is due to the advance of secularist currents, which are increasingly aggressive and capable of great media power, but there are also internal causes within Catholicism that explain the deterioration of a presence necessary for a growth in civilisation. A renewal of metaphysics is called for, to discover in being a congenital relationality that opens natural law to the interweaving of meaningful relationships, with a primacy of love over abstract rationality. With a renewed metaphysics, a philosophy of history can be founded, which is entirely necessary to guide political and cultural action. This book aims to briefly indicate the salient points to relaunch a sapiential thought consistent with the Christian faith, as the foundation of a secularism that transfigures the prevailing secularism.
