“Strong minds discuss ideas, average minds discuss events, weak minds discuss people.”

“Great minds discuss ideas. Average minds discuss events. Small minds discuss other people. Life's too short to worry about what other people do or don't do. Tend your own backyard, not theirs, because yours is the one you have to live in.”

“Intelligent people discuss ideas. Fools discuss how people should behave.”

“Hence the sterile, uninspiring futility of a great many theoretical discussions of ethics, and the resentment which many people feel towards such discussions: moral principles remain in their minds as floating abstractions, offering them a goal they cannot grasp and demanding that they reshape their souls in its image, thus leaving them with a burden of undefinable moral guilt.”

“I was of course discussing the book of Leviticus. I don't know why your mind is so filthy these days, Bingley.”
