The only part I don't quite get is here. To me, Polixenes is proposing quite directly that it will work, not that it does currently. So nature manages some kind of synthesis, through its processes, and perhaps we eventually say, yes, I recognize the beauty in this. Or we simply forget and see the new production as "natural" once again. But at first there's a hybrid, to which nature adapts... That makes sense to me, anyway, as I have a hard time thinking of nature as static.
