What is needed is a fellow-feeling between the different types of religion, seeing that they all stand or fall together, a fellow-feeling which springs from mutual esteem and mutual respect, and not the condescending, patronising, niggardly expression of goodwill, unfortunately in vogue at the present time with many. And above all, this is needed between types of religious expression coming from the study of mental phenomena — unfortunately, even now laying exclusive claim to the name of religion — and those expressions of religion whose heads, as it were, are penetrating more into the secrets of heaven though their feet are clinging to earth, I mean the so-called materialistic sciences.
