David Hume
“The rules of morality are not the conclusions of our reason.”
“The life of man is of no greater importance to the universe than that of an oyster.”
“Generally speaking, the errors in religion are dangerous; those in philosophy only ridiculous.”
“Be a philosopher; but, amidst all your philosophy, be still a man.”
“Custom is the great guide of human life.”
“Beauty in things exists in the mind which contemplates them.”
“A wise man proportions his belief to the evidence.”
“Reason is, and ought only to be the slave of the passions.”
