A Man Does Not Sin By Commission

Always Follow These Two Rules: First, Act Only On What Your Reasoning Mind Proposes For The Good Of Humanity, And Second, Change Your Opinion If Someone Shows You It's Wrong. This Change Of Mind Must Proceed Only From The Conviction That It's Both Correct And For The Common Good, But Not Because It Will Give You Pleasure And Make You Popular.

Is Any Man Afraid Of Change? Why What Can Take Place Without Change? What Then Is More Pleasing Or More Suitable To The Universal Nature?

It Never Ceases To Amaze Me: We All Love Ourselves More Than Other People, But Care More About Their Opinions Than Our Own.

No Man Is Happy Who Does Not Think Himself So.

He That Lives Alone Lives In Danger; Society Avoids Many Dangers.
