Of course, even if nurture is "winning the debate" (though it is hardly the only factor), Marx couldn't know about it. He didn't understand anything about genetics; he had no access to controlled statistical studies on human behavior.
I find it very silly when someone say: "see this ancient Greek philosopher was right all along! quantum physics says X, just like he did! He knew it!".
No he didn't.
Likewise, Marx couldn't possibly have anything useful to say about the "nature x nurture" debate, unless you credit him with prophetic powers. If he was right it is pure luck. He didn't conduct any scientific experiments to test his hypothesis. He didn't read anything about scientific experiments testing those hypothesis. In short, he didn't know. And if anyone wants to learn anything useful about that debate, Marx is not an useful source.
Yeah, and you don't understand the latest thinking in philosophy either, evidently.
As ReindeerThistle has said, it's really outmoded to suggest that something couldn't possibly be true if it was not yet known. And knowledge and scientific certainty are not the same. It's absurd to claim (with something akin to scientific certainty) that Marx couldn't have known anything useful about the nature vs nurture debate. While his knowledge was without a doubt imperfect (as is ours), he could certainly have known something about it, perhaps enough to point us in the right direction. We are, after all, talking about a human matter, and we can reasonably expect that Marx, being a human being and a member of a human society, could know something useful about the matter, no matter how unclearly defined this useful knowledge is.
