Quote by Whitehead, Alfred North
"Your enjoyment of the world is never complete unless you have left it better than you found it."
More from 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."
