which is an excellent tour through the many schools and theories that have emerged in economics over the last few centuries. It is a well balanced book including left and right, pro- and anti-capitalist perspectives. One gets a sense of the complexity of the subject without being put off. Rather it is like a series of puzzles, each theory trying to work out why the previous one, that seemed so plausible at the time, did not quite work out as expected. This, of course, often comes down to the fact that while humans do act rationally in some respects, they are also tricky customers who always try to double guess the system, whatever the system happens to be at the time. I enjoyed it a lot and recommend it to anybody who want to try to understand what is going on in the material world, but also as an interesting way of looking at human motives, aspirations and foibles.
