Quotes from the same author
Never trust a journalist unless she's your mother.
Nassim Nicholas Taleb
I have respect for mother nature's methods of robustness (billions of years allow most of what is fragile to break); classical thought is more robust (in its respect for the unknown, the epistemic humility) than the modern post-Enlightenment naïve pseudoscientific autism. Thus my classical values make me advocate the triplet of erudition, elegance, and courage; against modernity's phoniness, nerdiness and philistinism
Nassim Nicholas Taleb
If there is something in nature you don't understand, odds are it makes sense in a deeper way that is beyond your understanding. So there is a logic to natural things that is much superior to our own. Just as there is a dichotomy in law: 'innocent until proven guilty' as opposed to 'guilty until proven innocent', let me express my rule as follows: what Mother Nature does is rigorous until proven otherwise; what humans and science do is flawed until proven otherwise.
Nassim Nicholas Taleb
The number of managers with great track records in a given market depends far more on the number of people who started in the investment business (in place of going to dental school), rather than on their ability to produce profits.
Nassim Nicholas Taleb
There is a certain category of fool-the overeducated, the academic, the journalist, the newspaper reader, the mechanistic scientist, the pseudo-empiricist, those endowed with what I call epistemic arrogance, this wonderful ability to discount what they did not see, the unobserved.
