I Ought Never To Act Except In

Riches Ennoble A Man's Circumstances, But Not Himself.

Two Things Awe Me Most, The Starry Sky Above Me And The Moral Law Within Me.

Enlightenment Is Man's Emergence From His Self-imposed Nonage. Nonage Is The Inability To Use One's Own Understanding Without Another's Guidance. This Nonage Is Self-imposed If Its Cause Lies Not In Lack Of Understanding But In Indecision And Lack Of Courage To Use One's Own Mind Without Another's Guidance. Dare To Know!

In Man (as The Only Rational Creature On Earth) Those Natural Capacities Which Are Directed To The Use Of His Reason Are To Be Fully Developed Only In The Race, Not In The Individual.

If We Knew That God Exists, Such Knowledge Would Make Morality Impossible. For, If We Acted Morally From Fear Or Fright, Or Confident Of A Reward, Then This Would Not Be Moral. It Would Be Enlightened Selfishness.
