“One cannot escape dogmas—those who hold most firmly to dogmas today are those whose only dogma is that dogmas should be feared like the plague.”

“In truth, there are only two kinds of people; those who accept dogma and know it, and those who accept dogma and don't know it.”

“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.”

“Dogma in science really is humiliating when it is recognized as dogma.”

“Science has nothing to do with any dogma. Science ceases to exist when there is a dogma.”

“The bible is literature, not dogma.”
