“The modern world is filled with men who hold dogmas so strongly that they do not even know that they are dogmas. It may be said even that the modern world, as a corporate body, holds certain dogmas so strongly that it does not know that they are dogmas. It may be thought 'dogmatic,' for instance, in some circles accounted progressive, to assume the perfection or improvement of man in another world. But it is not thought "dogmatic" to assume the perfection or improvement of man in this world; though that idea of progress is quite as unproved as the idea of immortality, and from a rationalistic point of view quite as improbable. Progress happens to be one of our dogmas, and a dogma means a thing which is not thought dogmatic.”
