The World, the Flesh and the Devil: An Enquiry Into the Future of the Three Enemies of the Rational Soul by J. D. Bernal

Tough one to rate - an intellectual curiosity from 1929 that basically predates, predicts, and prophesies the tributaries of science and science fiction alike. As interesting for what it's right about as what is wrong.

Some predictions are so far flung they may not even be inaccurate - we just haven't caught up to the future.

-.5 for oddly specific Marxist sentiments at the end

3.5 cool cool cool
