In the movie Back to the Future II, Doc Brown and Marty McFly travel 30 years into the future, to today, October 21st, 2015. The movie was ahead of its time, at least when it came to marketing, apparently.
The movie also raised an important question which, alas, is still with us today, namely:
Suppose you could go back in time to hand a relatively recent work in philosophy to a pre-20th Century philosopher. Who would you visit, and what philosophical work would you deliver?
To put some parameters on the question:
Which philosophical work published after 1950 do you wish would have been read by which philosopher who died in 1900 or earlier?
