We are only falsehood, duplicity, contradiction; we both conceal and disguise ourselves from ourselves.

Man is obviously made for thinking. Therein lies all his dignity and his merit; and his whole duty is to think as he ought.

Man's greatness lies in his power of thought.

All our dignity lies in our thoughts.

Those who do not hate their own selfishness and regard themselves as more important than the rest of the world are blind because the truth lies elsewhere

All err the more dangerously because each follows a truth. Their mistake lies not in following a falsehood but in not following another truth.

There are people who lie simply for the sake of lying.
