The selfish smiling fool, and the sullen frowning fool, shall be both thought wise, that they may be a rod.

A fool sees not the same tree that a wise man sees.

If the fool would persist in his folly he would become wise.

This fellow is wise enough to play the fool;
And to do that well craves a kind of wit:
He must observe their mood on whom he jests,
The quality of persons, and the time,
And, like the haggard, check at every feather
That comes before his eye. This is a practise
As full of labour as a wise man's art
For folly that he wisely shows is fit;
But wise men, folly-fall'n, quite taint their wit.

A fool thinks himself to be wise, but a wise man knows himself to be a fool.

Great Men & Fools do often me InspireBut the Greater Fool the Greater Liar.
