This was going to be three stars (the third quarter was rather tiresome) but the last chapter and the introduction makes it 4. My heart weeped as Hardy suddenly took a humble turn, questioning whether his life has come to nothing through his pursuit of mathematics. I didn't really get too much insight into mathematics as a whole, and most of the points seemed trivial in places, but perhaps that is just the nature of Philosophy discussion. Hardy mentions that he might've made a decent philosopher, if he didn't pursue mathematics. I disagree, so why is this rated four stars? His candidness is valuable.

(P.S, I thought that his continual referral to relativity as 'useless' amusing! It's hard to remember when this book was written when you have a modern copy in your hands.)
