Xavier Tilliette, a French Jesuit, recognized for his expertise in the history of German idealism – Schelling in particular – taught in both Paris and Rome. He is also known for his studies in philosophical Christology. These two dimensions of his thought, both philosophical and theological, are united in a spiritual attitude that existentialist concern brought to philosophy. Schelling’s texts on evil offer him arguments to develop his thinking. This is born in the mentality of French reflexive analysis (Lequier). It is developed in France when Schelling’s studies multiplied there (Bruaire). It energizes his philosophical friendships with Italian philosophers such as Luigi Pareyson.
