Just before leaving for Europe in 1928, Tate described himself to John Gould Fletcher as "an enforced atheist". He later told Fletcher, "I am an atheist, but a religious one — which means that there is no organization for my religion." He regarded secular attempts to develop a system of thought for the modern world as misguided. "Only God," he insisted, "can give the affair a genuine purpose." In his essay "The Fallacy of Humanism" (1929), he criticized the humanists of his time for creating a value system without investing it with any identifiable source of authority. "Religion is the only technique for the validation of values," he wrote. Although he was attracted to Roman Catholicism, he deferred converting. Louis D. Rubin, Jr. observes that Tate may have waited "because he realized that for him at this time it would be "only" a strategy, an intellectual act".
