Actually, this is common in MANY early cultures, and still persists in many indigenous cultures. And for most of them, it wasn't just one they couldn't care for, it was one that was "defective" in any way: missing or misshapen limbs, ambiguous genitalia, down syndrome, etc.Whistler wrote:oh, weird. Hysteric pregnancy is really weird too. Speaking of infanticide, sometimes Inuit women would leave a baby they couldn't care for to die. It kind of makes sense but it's also brutal and sad.
The one that comes to mind most easily right now is the ancient Greeks (and it wasn't just Sparta.) Mostly because recently while talking about theater, my professor said something along the lines of "yeah, they gave us theater and democracy but also infanticide, so I guess you take the good with the bad."
