Virtue is a habit of the mind, consistent with nature and moderation and reason.

In the conduct of almost every affair slowness and procrastination are hateful

That man is guilty of impertinence who considers not the circumstances of time, or engrosses the conversation, or makes himself the subject of his discourse, or pays no regard to the company he is in.

A bureaucrat is the most despicable of men, though he is needed as vultures are needed, but one hardly admires vultures whom bureaucrats so strangely resemble. I have yet to meet a bureaucrat who was not petty, dull, almost witless, crafty or stupid, an oppressor or a thief, a holder of little authority in which he delights, as a boy delights in possessing a vicious dog. Who can trust such creatures?

For he, indeed, who looks into the face of a friend beholds, as it were, a copy of himself.

It is not only arrogant, but it is profligate, for a man to disregard the world's opinion of himself.

No wise man has called a change of opinion in constancy.
