MULTITUDE, n.
A crowd; the source of political wisdom and virtue. In a republic, the object of the statesman's adoration. "In a multitude of counsellors there is wisdom," saith the proverb. If many men of equal individual wisdom are wiser than any one of them, it must be that they acquire the excess of wisdom by the mere act of getting together. Whence comes it? Obviously from nowhere--as well say that a range of mountains is higher than the single mountains composing it. A multitude is as wise as its wisest member if it obey him; if not, it is no wiser than its most foolish.
--Ambrose Bierce - The Devil's Dictionary
