Lie not, neither to thyself, nor man, nor God. It is for cowards to lie.

When you want to help people, you tell them the truth. When you want to help yourself, you tell them what they want to hear.

If you want to be successful, you must respect one rule: never lie to yourself.

Confidence…thrives on honesty, on honor, on the sacredness of obligations, on faithful protection and on unselfish performance. Without them it cannot live.

The liar is no better than the thief, and if his mendacity takes the form of slander he may be worse than most thieves. It puts a premium upon knavery untruthfully to attack an honest man, or even with hysterical exaggeration to assail a bad man with untruth.

The truth is not wonderful enough to suit the newspapers; so they enlarge upon it and invent ridiculous embellishments.

A man may imagine things that are false, but he can only understand things that are true.

If you compromise your own conscience, you will weaken your conscience. Soon your conscience will fail to guide you and you never will have real wealth based on peace of mind.

Everything you said should be true but not everything true should be said.

A thief is a man in need. A liar is a man in fear.

For truth is precious and divine—too rich a perl for carnal swine.

You assist an evil system most effectively by obeying its orders and decrees. An evil system never deserves such allegiance. Allegiance to it means partaking of the evil. A good person will resist an evil system with his or her whole soul.

Without courage, we cannot practice any other virtue with consistency. We can't be kind, true, merciful, generous, or honest.
