Religion Without God, first published in 1928, is a continuation of Sheen’s God and Intelligence in Modern Philosophy (1925). Taken together, the two are a complete philosophy of religion. The modern mind remains greatly concerned with religion, and yet its concern is coldly theoretical, admitting of no practical sensibility of the relationship between God and man. The result is an emptying of all theological content from religion, reducing it to mere humanism. As a corrective, Sheen first offers a threefold analysis of the ideas behind modern religion: expository, historical, and critical; second, he presents the constructive, intelligible, and natural foundation for religion. From the pen of a peerless apologist, Religion Without God is a calm, measured study of the assumptions and arguments of nineteenth- and twentieth-century religious thought—concepts and claims still active in the twenty-first century’s project of secularization.
