“Wise men speak only of what they know”
“I have always found that Angels have the vanity to speak of themselves as the only wise.”
“it is not only he who speaks contrary to what he knows who lies, but even more he who speaks contrary to what he does not know”
“A smart man only believes half of what he hears, a wise man knows which half.”
“For to fear death, my friends, is only to think ourselves wise without really being wise, for it is to think that we know what we do not know. For no one knows whether death may not be the greatest good that can happen to man.”
