Separately, is it still pain if you’re not conscious of it?
Doctors used to assert that babies didn’t feel pain, because 1) they couldn’t tell us about it, and 2) they didn’t remember it later. They would just not anesthetize babies. Of course, that endpoint of this line of reasoning is horrifying, but it’s still a fair question. When we say “pain” do we mean the firing of the nerves, or do we mean awareness of it?
