About David Hume

1711 – 1776

Scottish philosopher and historian.

“Nothing is more dangerous to reason than the flights of the imagination.”

“Morals excite passions, and produce or prevent actions. Reason of itself is utterly impotent in this particular.”

“Reason is wholly inactive, and can never be the source of so active a principle as conscience, or a sense of morals.”

“He is a wise man who does not grieve for the things which he has not, but rejoices for those which he has.”

“The man who asks a question is a fool for a minute, the man who does not ask is a fool for life.”
