(Late-breaking epistemic status: I still stand behind the definitional claim in the title, but my attempt to draw connections between the definitional claim and the moral argument were not very coherent. Also, many people reading this clearly think that “population” just means the sum of individuals, so I’ve clearly got more work to do in that area of the argument as well.)
I’ve recently noticed some advocates of human genetic engineering claim that eugenics is actually a good thing. I’m pretty sure the majority of these people are not in favor of of “eugenics” as the term has historically been used, and I think misusing the word in this way has bad consequences. The distinction I’m about to draw is often ignored in public debate, but it is both pragmatic and morally necessary.
