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.

When High and Mighty people want to make us believe that they possess some good quality which they in fact do not have, it is dangerous to show that you doubt them; because, by removing their hope of deceiving the world, you also remove their desire to perform the good acts that might have arisen from their very pretensions.

We would often rather seem dutiful to others than to succeed in our duties; and often we would rather tell our friends that we have done them good than to do good in actuality.

Although we should not love our friends for the good that they do us, it is a sign that they do not love us much if they do not do us good when they have the power to do so.

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.

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.

There is always enough self-love hidden beneath the greatest devoutness to set limits on charity.
