Confucius said, “By nature, men are nearly alike; by practice (habit), they get to be wide apart.” 「性相近也,習相遠也。」The English is Legge’s translation. I’m told that a more literal translation reads: “By nature men are close to each other, by practice(habit) they are far from each other” (Book XVII of The Analects).
