Heinlein And Marx

"Remember Karl Marx and note how close that unscientific piece of nonsense called Das Kapital has come to smothering out all freedom of thought on half a planet..."
-Robert Heinlein, Concerning Stories Never Written: Postscript (This was printed in an edition of Heinlein's Revolt In 2100. I quote from a photocopy posted to me by Sean M. Brooks.)

Heinlein's Future History, including this explanatory postscript to Volume III, is a masterpiece. I must say that before going on to remark that Heinlein wrote a great deal of "nonsense" later!

I quote Heinlein in the light of the previous post. We can read political theories for understanding or future histories for pleasure but, in either case, we engage in a single debate about the nature of mankind and our place in the universe.
