I can't remember if it was via reading Douglas Hofstadter, Daniel Dennett, William Poundstone (or someone writing in a similar vein) that I came across Smullyan but his name cropped up in many things that have captivated me over the years. This dialogue is absolutely marvellous: http://www.mit.edu/people/dpolicar/writing/prose/text/godTao...
Re: Raymond Smullyan has died
#61It might have been Hofstadter and Dennett's "The Mind's I" which includes both "Is God a Taoist?" and "An Unfortunate Dualist"
