"Fables should be taught as fables, myths as myths, and miracles as poetic fancies. To teach superstitions as truths is a most terrible thing."

"Truth does not change because it is, or is not, believed by a majority of the people."

"He who influences the thought of his times influences all the times that follow."

"The only way to make sense out of change is to plunge into it, move with it, and join the dance."

"Superstition is cowardice in the face of the Divine."
