Quote by Gu Dingfang

“Great minds that are healthy are never considered geniuses, while this sublime qualification is lavished on brains that are often inferior but are slightly touched by madness.”

“The man who never alters his opinion is like standing water, and breeds reptiles of the mind.”

“What reasons have you to envy anything?”

“The former was superstition; the latter is undisguised egoism.”
