Everyone is so caught up in his own passions and interests that he always wants to talk about them without getting involved in the passions and interests of those to whom he speaks, although his listeners have the same need for others to listen to and help them.
There is a certain manner of self-absorption in speaking that always renders the speaker disagreeable. For it is as great a folly to listen only to ourselves while we are carrying on a conversation with others as it is to talk to ourselves while we are alone.
Criticism should awaken our attention, not inflame our anger. We should listen to, and not flee from, those who contradict us. Truth should be our cause, no matter in what manner it comes to us.
