Why did I love this book?
No author has had a greater impact on my thinking about entrepreneurship than Frank Knight.
He explained that entrepreneurs do not maximize anything, since the future is uncertain in a non-probabilistic sense. Instead they exercise judgment while facing an unknown future.
This book is divided into three parts. The first two parts read like a conventional economics textbook, but the third part is phenomenal. He explains why risk and uncertainty are different, which is a lesson that many economists and other social scientists still disregard.
