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.
To see a man fearless in dangers, untainted with lusts, happy in adversity, composed in a tumult, and laughing at all those things which are generally either coveted or feared, all men must acknowledge that this can be from nothing else but a beam of divinity that influences a mortal body.
