There's an expression in Yiddish, which is "der gelernte naar" - a "learned fool." You can know a great deal, you can have a Ph.D., and you can still be a total idiot.
The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
Knowledge descries; wisdom applies.
The experience of others adds to our knowledge, but not to our wisdom; that is dearer bought.
A man of over thirty might be held to be at the height of his powers, but not necessarily of his wisdom.
Knowledge is flour, but wisdom is bread.
Never confuse acquiring degrees with wisdom.
He who thinks he knows, doesn't know. He who knows that he doesn't know, knows.
In a sense, knowledge shrinks as wisdom grows: for details are swallowed up in principles.
Forasmuch as many people study more to have knowledge than to live well therefore ofttimes they err and bring forth little fruit or none.
Knowledge is one thing. We're awash in knowledge. Wisdom is rare. There's a big difference.
