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.

He who uses trickery should at least make use of his judgment to learn that he can scarcely hide treacherous conduct for very long among clever men who are determined to find him out, although they may pretend to be deceived in order to disguise their knowledge of his deceitfulness.

We nearly always make ourselves masters of those whom we know well, because he who is thoroughly understood is in some sense subject to those who understand him.

It is sometimes useful to pretend we are deceived, because when we show a deceiving man that we see through his artifices, we only encourage him to increase his deceptions.

There is no more reason to accuse ourselves excessively of our failings than to excuse them overmuch. He who goes overboard in self-criticism often does so in order not to suffer others' criticisms, or else does so out of a kind of vanity that wishes to make others believe that he knows how to confess his faults.

It is better that great peoples should seek out glory, or even vanity, in their deeds, than that they should remain indifferent . For even if they are not incited to act upon virtuous principles, at least there is the saving grace that they will do things they might not have done had not vanity prompted their actions.

Just as there is no action weaker or more unreasonable than to submit one's judgment to another's, where there is no advantage to oneself, so also there is nothing greater or wiser than to place oneself unquestioningly under God's judgment by believing in every word He speaks.
