“There are no superstitions but those you invent”
“The need of exercise is a modern superstition, invented by people who ate too much and had nothing to think about. Athletics don’t make anybody long-lived or useful.”
“You may substitute knowledge for superstition without satisfying the needs that drive people into superstition's arms.”
“Men are in fact, quite unable to control their own inventions; they at best develop adaptability to the new conditions those inventions create.”
“If you let the alembic cool, metaphor becomes superstition.”
“Superstitious." What a strange word. If you believed in Christianity or Islam, it was called "faith". But if you believed in astrology or Friday the thirteenth it was superstition! Who had the right to call other people's belief superstition?”
