...it is a mark of prudence never to place our complete trust in those who have deceived us even once.

Men of genius are admired, men of wealth are envied, men of power are feared, but only men of character are trusted.

All men having power ought to be distrusted to a certain degree

It is prudent never to trust those who have deceived us, even if only once.

You should not honor men more than truth.

To believe all men honest would be folly. To believe none so, is something worse.

who can you trust?

It is better to believe in men too rashly, and regret, than believe too meanly. Men could be more than they are, if they would try for it. He has shown them that.

But thus do I counsel you, my friends: distrust all in whom the impulse to punish is powerful!

Let these innocent people be careful not to invest in corporations where those in control are not men of probity, men who respect the laws; above all let them avoid the men who make it their one effort to evade or defy the laws.

never trust a man who won't accept that there is more than one way to spell a word

Paraphrased

It is better to believe in men too rashly, and regret, than believe too meanly. Men could be more than they are, if they would try for it. He has shown them that. How many have tried, because of him? Not only those I have seen; there will be men to come. Those who look in mankind only for their own littleness, and make them believe in that, kill more than he ever will in all his wars.

Never overtly show all men the contempt which they deserve, for one can never know when one may need them.

Trust not your security to one who puts his own interests first.
