read this book and spin your brain
on 19 January 2014
I wish i could live in the same world as Raymond Smullyan! How does he get the time to think up these conundrums? Well, mostly it is his day job, and he gets paid to chat about these things to other academics. But what conversations! How i would love to be there. All of these problems are about language and how we use it, especially the words "true" and "false" and "lie", and about how complicated things can get if you think about those words hard enough -- while being far from dryasdust. you are drawn into a world where you have to think of a way of checking that your travelling companion is not a vampire, where you have a logical proof that Santa Claus exists, and Inspector Craig of Scotland Yard shows you how to analyse the meagre facts you have on suspects. My advice is buy this book, and lend it to nobody.
