Very good text that I recommend reading from cover to cover. Polanyi is also an excellent introduction to non-Marxist, yet socialist theory. I also recommend reading a bit about Karl Polanyi's brother, Michael Polanyi – a polymath and philosopher of science, known for inventing the concept of 'tacit knowledge' and for his anti-positivist views. The ideologies of the Polanyi brothers couldn't be more different. Interesting case.
