Notably, humanity does not deem sex slavery, pedophilia, the gunning down of helpless little children, brutality, democide, gang rape, racism or even serial homicide as merely socially improper conduct, like, say, picking your nostrils at the dinner table. Much rather, these jolt, outrage as well as horrify. They’re confronted as morally abominable facts -as undeniable acts of evil. (This is why, since time immemorial, even the most primitive cultures, regardless of their spiritual values, enforced laws and regulations against homicide and various other acts of evil.)
On the flip side, love, equality or self-sacrifice are more than just socially useful acts, like, say, bringing a lady roses on a first date. Rather, these are regarded as good moral facts; conduct which is actually good.
That said, irrational beasts don't possess such **objective** morals. Just about everything they do is the denouement of behavioral instinct not shared knowledge handed down from one era to the next, their woefully limited cognition notwithstanding. So whenever a lion savagely kills some other, it doesn't believe it's committing homicide. Any time a peregrine falcon or a bald eagle snatches prey away from another, it doesn't think it's stealing. Each time primates violently force themselves onto females as well as their little ones they’re not tried and convicted of rape or pedophilia. Needless to say, we undoubtedly didn't “inherit” our **objective** moral sense from these.
**Objective** morals are never derived from scientific research because science, by its very nature, is morally nihilistic. From where, then perhaps, did we obtain our **universal objective morals**?
Consider the following:
(1) If God does not exist, objective moral values and duties don't exist.
(2) If evil exists, objective moral values and duties exist.
(3) Evil exists.
(4) Therefore, objective moral values and duties do exist.
(5) Therefore, God exists.
(6) Therefore, God is the locus of all objective moral values and duties.
That's to say, as Dostoevsky once mused, "If there is no God, everything is permitted."
