“Morality is not really the doctrine of how to make ourselves happy but of how we are to be worthy of happiness”
Immanuel Kant
“When the doctrine of allegiance to party can utterly up-end a man's moral constitution and make a temporary fool of him besides, what excuse are you going to offer for preaching it, teaching it, extending it, perpetuating it? Shall you say, the best good of the country demands allegiance to party? Shall you also say it demands that a man kick his truth and his conscience into the gutter, and become a mouthing lunatic, besides?”
Mark Twain
“I am an Epicurean. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greek and Roman leave to us.”
Thomas Jefferson
“I reject any religious doctrine that does not appeal to reason and is in conflict with morality.”
Mohandas Gandhi
“Morality is not the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.”
Imannuel Kant
“My doctrine is not a doctrine but just a vision. I have not given you any set rules, I have not given you a system.”
Buddha
“Nearly all the philosophical and mathematical doctrines attributed to Pythagoras are derived from India”
Ludwig von Schroder
