Melbourne Philosopher asks: "who are your all time, desert-island, top 5 philosophers?" I haven't read very widely yet, so my selection pool is rather limited, but here goes...
1. J. S. Mill
5. Douglas Adams [hey, if MP could choose Heinlein... ;)]
To develop the meme, I'll add my top 5 philosophers I feel guilty about not having read:
4. David Lewis
What do your lists look like?
