All things are cause for either laughter or weeping.

There are no greater wretches in the world than many of those whom people in general take to be happy.

We pardon familiar vices.

The rust of the mind is the destruction of genius.

No one can be happy who has been thrust outside the pale of truth. And there are two ways that one can be removed from this realm: by lying, or by being lied to.

Why does no one confess his sins? Because he is yet in them. It is for a man who has awoke from sleep to tell his dreams.

A good conscience fears no witness, but a guilty conscience is solicitous even in solitude. If we do nothing but what is honest, let all the world know it. But if otherwise, what does it signify to have nobody else know it, so long as I know it myself? Miserable is he who slights that witness.
