This philosophical study examines the problem of God within the thought of Jean Nabert (1881–1960), a significant yet often overlooked figure in 20th-century French philosophy. The work analyzes Nabert's engagement with themes of consciousness, moral experience, and the divine, situating his ideas within broader currents of existential and post-Kantian thought. Published by Presses Universitaires Blaise Pascal, the book offers a rigorous scholarly treatment of Nabert's contributions to philosophy of religion and his distinctive approach to questions of transcendence, evil, and human aspiration. It serves as both an introduction to Nabert's complex philosophical system and a critical assessment of his relevance to contemporary debates in metaphysics and ethics.
