To Your Scattered Bodies Go by Philip José Farmer

This one wasn't a Joint Winner, but did win the Hugo in 1972. The title is amazing. And the book is extremely Fun and Short.

Page One: Sir Richard Francis Burton is dying in his wife's arms in the city of Trieste of the Austro-Hungarian empire of 1890. He wakes up. He's floating in a limitless space, filled with other naked, hairless, sleeping bodies. He makes a fuss and is put back to sleep by some aliens in a floating canoe. He wakes up again, next to a river, with a bucket on his wrist, and with thousands of other naked hairless humans, also with buckets attached to their wrists, waking up around him. These other humans died at various points in Earth's history--from prehistoric times to the 21st century, but they are all waking up at the same moment. Some of them think this is Heaven. Most don't. The story goes on from there, quickly.

My 19th Century history knowledge is poor unless it has to do with the US Old West. So if nothing else, this book made me look up a bit about Sir Richard Francis Burton and his (extensive) doings.

Philosophy? Maybe not so much here. But a fun story, full of fun hypotheticals.
