“Once experience is admitted within the theological edifice, the latter begins to crumble – such portion of it, of course, as stands within the experimental domain, for the other wings are safe from any attack by experience. So years, centuries, go by; peoples, governments, manners and systems of living, pass away; and all along new theologies, new systems of metaphysics, keep replacing the old, and each new one is reputed more “true” or much “better” that its predecessors. And in certain cases they may really be better, if by “better” we means more helpful to society; but more “true”, no, if by the term we mean accord with experimental reality. One faith cannot be more scientific than another, and experimental reality is equally overreached by polytheism, Islamism, and Christianity (whether Catholic, Protestant, Liberal, Modernist, or of any other variety); by the innumerable metaphysical sects, including the Kantian, the Hegelian, the Bergsonian, and not excluding the positivistic sects of Comte, Spencer, and other eminent writers too numerous to mention; by the faiths of solidaristes, humanitarians, anti-clericals, and worshippers of Progress; and by as many other faiths as have existed, exist, or can be imagined.”
