Of all the animals, man is the only one that lies.

Every lie is a poison; there are no harmless lies. Only the truth is safe. Only the truth gives me consolation - it is the one unbreakable diamond.

To believe in something, and not to live it, is dishonest.

There is poison in the fang of the serpent, in the mouth of the fly and in the sting of a scorpion; but the wicked man is saturated with it.

I do not like an injurious lie, except when it injures somebody else.

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.
