Quote by Whitehead, Alfred North

"The true method of discovery is like the flight of an aeroplane. It starts with the ground of particular observation; it makes a flight in the thin air of imaginative generalization; and it again lands for renewed observation rendered acute by rational analysis."

"Civilization advances by extending the number of important operations which we can perform without thinking about them."

"The paradox is only a conflict between reality and your feeling of what reality ought to be."

"There are no whole truths; all truths are half-truths. It is trying to treat them as whole truths that plays the devil."

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
