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.

The mind is never right but when it is at peace within itself.

He is not guilty who is not guilty of his own free will.

Eyes will not see when the heart wishes them to be blind.

Friendship always benefits; love sometimes injures.

We should every night call ourselves to an account: What infirmity have I mastered today? What passions opposed? What temptation resisted? What virtue acquired? Our vices will abate of themselves if they be brought every day to the shrift.
