Nothing can now be believed which is seen in the newspaper. Truth itself becomes suspicious by being put into that polluted vehicle.

The quick pain of truth can pass away, but the slow eating agony of a lie is never lost.

No man, for any considerable period, can wear one face to himself, and another to the multitude, without finally getting bewildered as to which may be true.

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

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 like a lion; you don’t have to defend it. Let it loose; it will defend itself.

When whole races and peoples conspire to propagate gigantic mute lies in the interest of tyrannies and shams, why should we care anything about the trifling lies told by individuals?

We hang the petty thieves and appoint the great ones to public office.

It wasn't until late in life that I discovered how easy it is to say "I don't know."

If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.

Knowledge rests not upon truth alone, but upon error also.

It's the truth I'm after, and the truth never harmed anyone. What harms us is to persist in self-deceit and ignorance.

The greatest kindness one can render to any man is leading him to truth.
