One may sometimes tell a lie, but the grimace that accompanies it tells the truth.

All truth is simple... is that not doubly a lie?

He who does not need to lie is proud of not being a liar.

The most fatal seductive lie that has yet existed.

The great lie about immortality destroys every kind of reason, every kind of naturalness in the instincts.

The love of truth has its reward in heaven and even on earth.
