“Inevitably even the most original new ideas will eventually harden into dogma or stop working for everybody.”

“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible.”

“The problem starts at the secondary level, not with the originator or developer of the idea but with the people who are attracted to it, who adopt it, who cling to it until their last nail breaks, and who invariably lack the overview, flexibility, imagination, and, most importantly, sense of humor, to maintain it in the spirit in which it was hatched. Ideas are made by masters, dogma by disciples, and the Buddha is always killed on the road.”

“It would in retrospect appear to be a stop on a narrative path that was inevitable, but this is only because most events, most paths, feel inevitable in retrospect.”

“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.”

“The mind, once stretched by a new idea, never returns to its original dimensions.”
