Of course, I very much enjoyed his chapter on self-referential problems with the constitution, because I thought it was funny and interesting. However, the interesting part was not the application of mathematics in politics but the discussion of odd situations that can arise in politics. (He correctly argues that Godel's result yields no substantial conclusions for politics. Then why talk about it in a book on politics? Its only value is as a metaphor, and a weak one at that.)
On a side note, I know this isn't a forum, but the pedant in me must correct the previous reviewer. If we define a function, f(x)=(x^2-1)/(x-1), then f(x) is defined only when x is not equal to 1. In that case f(1) is undefined (because f(1)=0/0), and it makes no sense to cancel the common factors (x-1). Or to put it another way, this cancellation is only valid when x is not equal to 1. Otherwise, we would be cancelling a factor zero from the numerator and denominator (and no number except 0 has 0 as a factor). To put it yet another way, suppose we want to say that f(x) is equivalent to (x+1), as the previous reviewer does. If we do this, we must remember that we reached this result only by assuming we could cancel (x-1) from the numerator and denominator. Again this cancellation is only valid when x is not 1. Therefore, f(x)=(x+1) only when x is not equal to 1. Sorry, but I couldn't stand the thought of someone out there being misled on this point.
