In a famous speech in the 1990s, Charlie Munger summed up this approach to practical wisdom: โWell, the first rule is that you canโt really know anything if you just remember isolated facts and try and bang โem back. If the facts donโt hang together on a latticework of theory, you donโt have them in a usable form. You’ve got to have models in your head. And you’ve got to array your experience both vicarious and direct on this latticework of models. You may have noticed students who just try to remember and pound back what is remembered. Well, they fail in school and in life. You’ve got to hang experience on a latticework of models in your head.โ
