“Would you kill babies if it was inherently the right thing to do? Yes  No ”
“Imagine that you wake up one morning and your left arm has been replaced by a blue tentacle. The blue tentacle obeys your motor commands—you can use it to pick up glasses, drive a car, etc.
How would I explain the event of my left arm being replaced by a blue tentacle? The answer is that I wouldn’t. It isn’t going to happen. ”
If morality was objective and it said we should kill babies, we’d have, and likely want to do it. Appears it isn’t objective, though, and that we just don’t feel that way. Another question ?
