This book makes a great companion to Scott's Seeing Like a State, and the review connects some of the ideas and runs with it. The reviewer also does a great job of bringing Polyani's ideas (the book was written in 1944) to the present to see how they do. I'm going to read this two or three times, I think, and still be stewing over what it all has to say. It's not that it's especially dense, but that there's just a lot of really interesting ideas here.
