Knowledge Comes From Experience and Trial and Error
I have shown in Antifragile that most things that we believe were “invented” by universities were actually discovered by tinkering and later legitimized by some type of formalization. The knowledge we get by tinkering, via trial and error, experience, and the workings of time, in other words, contact with the earth, is vastly superior to that obtained through reasoning, something self-serving institutions have been very busy hiding from us.
Experience and doing first; explanation and theory after.
