The attempts to reconstruct religious creeds are beset by the modern man’s inability to convince himself that the constitution of the universe includes facts which in our skeptical jargon we call supernatural. Yet as William James once said, “religion, in her fullest exercise of function, is not a mere illumination of facts already elsewhere given, not a mere passion, like love, which views things in a rosier light.... It is something more, namely, a postulator of new _facts_ as well.” James himself was strongly disposed toward what he so candidly described as “overbeliefs”; he had sympathy with the beliefs of others which was as large and charitable as any man’s can be. There was no trace of the intellectual snob in William James; he was in the other camp from those thin argumentative rationalists who find so much satisfaction [p025] in disproving what other men hold sacred. James loved cranks and naifs and sought them out for the wisdom they might have. But withal he was a modern man who lived toward the climax of the revolutionary period. He had the Will to Believe, he argued eloquently for the Right to Believe. But he did not wholly believe. The utmost that he could honestly believe was something which he confessed would “appear a sorry underbelief” to some of his readers. “Who knows,” he said, “whether the faithfulness of individuals here below to their own poor overbeliefs may not actually help God in turn to be more effectively faithful to his own greater tasks?” Who knows? And on that question mark he paused and could say no more. 3. _God in More Senses Than One_ But even if there was some uncertainty as to the existence of the God whom William James described, he was at least the kind of God with whom human beings could commune. If they could jump the initial doubt they found themselves in an exciting world where they might live for a God who, like themselves, had work to do. James wrote the passage I have quoted in 1902. A quarter of a century later Alfred North Whitehead came to Harvard to deliver the Lowell Lectures. He undertook to define God for modern men.
