Anything more than the truth would have seemed too weak.

Everything can be sacrificed for truth, but truth cannot be sacrificed for anything.

Never tell the truth to people who are not worthy of it.

Homely truth is unpalatable.

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

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.
