Yeah, but you keep adding these becauses and kicking it down a level. What do you just see? That it's good for survival and happiness (which refers back again to survival)?
Survival is a pretty low moral value, perhaps the lowest, even lower than "feels good."
Isn't there something more to the golden rule's value?
Really? The want to live, and let live, is a low moral value?
What can be more valuable than to be critical in sustaining life?
