The author aims to sketch out a biographical and philosophical profile of Alberto Caracciolo (1918-1990), Italian philosopher in the second half of the twentieth century. In order to reach a better understanding of the philosopher’s religious point of view, he believes it is necessary to emphasize both Caracciolo’s juvenile friendship with Teresio Olivelli (1916-1945) - martyr of the resistance against Nazism - and his critical engagement with the thought of great philosophers such as Croce, Leopardi, Kant, Troeltsch, Jaspers and Heidegger. The author intends also to analyze how Caracciolo’s renewal of religious tradition, reconsidered through the concept of Liberalität, connected with his restless and anxious way of considering the malum mundi, led towards an original interpretation of European nihilism. This involves an idea of philosophy, linked to an inexhaustible question and to an ethical and religious view of human life, grounded in a paradoxical way on the imperative of eternity.
