George Bernard Shaw Wisdom and knowledge decrease in inverse proportion to age. William J. Lynott Wisdom is considered a sign of weakness by the powerful because a wise man can lead without power but only a powerful man can lead without wisdom. An expert is one who knows more and more about less and less. Nicholas Murray Butler Real knowledge is to know the extent of one's ignorance. Pope Julius III He who knows only his own side of the case knows little of that.
Wise men write many books, in words too hard to understand.
But this, the purpose of our lives, the end of all our struggle, is beyond all human wisdom. Alan Paton People who know little are usually great talkers, while men who know much say little. It is better, of course, to know useless things than to know nothing. Seneca It is better to know some of the questions than all of the answers. The only things one can admire at length are those one admires without knowing why.
