I had a similar experience with Descent of Man Revisited (see previous post): I sent the OWS over ten copies plus of the book, and these soon materialized at Amazon’s second hand market. Fine: but the failure to take a leftist movement into the postdarwinian zone is a mistake. It doesn’t seem like a mistake: it seems like the only course for groupies of the New Atheist, half-assed leftist/marxist crowd. But I think times are changing and there will be no left of the future based on the kind of sterile darwinism that began with the 2nd Internationale.
Last and First Men, I can see, will be immediately set aside by such as the OWS in favor of something that conforms to the reigning ideology. Your loss.
