"Speak not in high commendation of any man to his face, nor censure any man behind his back; but if thou knowest anything good of him, tell it unto others; if anything ill, tell it privately and prudently to himself."

Self-love makes us deceive ourselves in almost all matters, to censure others, and to blame them for the same faults that we do not correct in ourselves; we do this either because we are unaware of the evil that exists within us, or because we always see our own evil disguised as a good.
