Distrust.

To safeguard man from wrongs, there nothing must
Be truer to him than a wise distrust.
And to thyself be best this sentence known:
Hear all men speak, but credit few or none.

He that will live of all cares dispossess'd,
Must shun the bad, aye, and suspect the best.

Trust me, ladies, I will do
Nothing to distemper you;
If I any fret or vex,
Men they shall be, not your sex.

We trust not to the multitude in war,
But to the stout, and those that skilful are.

No wrath of men, or rage of seas,
Can shake a just man's purposes;
No threats of tyrants, or the grim
Visage of them can alter him;
But what he doth at first intend,
That he holds firmly to the end.

Words beget anger; anger brings forth blows;
Blows make of dearest friends immortal foes.
For which prevention, sociate, let there be
Betwixt us two no more logomachy.
Far better 'twere for either to be mute,
Than for to murder friendship by dispute.
