MOVING TO FRONT FROM YESTERDAY–I'LL LET THIS RUN ABOUT ANOTHER DAY OR SO, AND POST RESULTS BY FRIDAY

We haven't had a poll in awhile, so here's a new one.  74 choices (you don't have to rank them all!), across all fields.  Only those philosophers over 70 in 2017 or no longer living are included.   I'll post the top 10 (maybe the top 20), I hope I've got all viable candidates for the top 10 or 20 among the choices.  Have fun!

UPDATE:  Some errors of omission called to my attention:  Philip Kitcher, Ruth Millikan, Richard Rorty, Peter van Inwagen.  I doubt, though, any of these eminent philosophers would have made the top ten or twenty, but I'm sorry to have left them off.

ANOTHER:  As several readers pointed out the last half-century would be 1967, not 1957, as marked in the poll.  Since 1957 was the benchmark, I've changed the title of the poll!
