A tip of the hat to Mark Crosby for turning me on to Robert Rosen. He’s not another one of these new age cranks, is he? I notice the Wiki link talks about teleology, which evokes a knee-jerk reaction in me whenever I encounter it. I don’t see why we can’t banish teleological descriptions from biology, describing biological processes as essentially chemical processes. “Chemical A is released, triggering chemical B, etc.” Isn’t this essentially the way Deleuze describes the unfolding of an egg? I must be missing something. Whatever the case me be, it’s nice to know that my intuitions about category theory are shared by others. Is there anything you haven’t read Mark?
