The less talent they have, the more pride, vanity and arrogance they have. All these fools, however, find other fools who applaud them.Desiderius Erasmus
I'm all in favor of keeping dangerous weapons out of the hands of fools. Let's start with typewriters.Frank Lloyd Wright
Because people have no thoughts to deal in, they deal cards, and try and win one another's money. Idiots!Arthur Schopenhauer
Experience - the wisdom that enables us to recognise in an undesirable old acquaintance the folly that we have already embraced.Ambrose Bierce
We shall not grow wiser before we learn that much that we have done was very foolish.Friedrich August von Hayek
Superstition is to religion what astrology is to astronomy the mad daughter of a wise mother. These daughters have too long dominated the earth.Voltaire
The folly of mistaking a paradox for a discovery, a metaphor for a proof, a torrent of verbiage for a spring of capital truths, and oneself for an oracle, is inborn in us.Paul Valery
Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.Charles Spurgeon
