Humor is the good natured side of a truth.

The false can never grow into truth by growing in power.

The truth hurts, but silence kills.

Among other common lies, we have the silent lie - the deception which one conveys by simply keeping still and concealing the truth. Many obstinate truth-mongers indulge in this dissipation, imagining that if they speak no lie, they lie not at all.

If you tell the truth, you don't have to remember anything.

When in doubt tell the truth. It will confound your enemies and astound your friends.
