This is a privilege I take advantage of, and every day I plead my case before myself as a judge. When the lamp has been removed from my sight, and my wife, no stranger now to my habit, has fallen silent, I examine the whole of my day and retrace my actions and words; I hide nothing from myself, pass over nothing. For why should I be afraid of any of my mistakes, when I can say: ‘Beware of doing that again, and this time I pardon you. In that discussion you spoke too aggressively: do not, after this, clash with people of no experience; those who have never learned make unwilling pupils. You were more outspoken in criticizing that man than you should have been, and so you offended, rather than improved him: in the future have regard not only for the truth of what you say but for the question whether the man you are addressing can accept the truth: a good man welcomes criticism, but the worse a man is, the fiercer his resentment of the person correcting him’?

Seneca, ‘On Anger’
