That’s the problem Freddy because objective morality was the whole point. let’s go back to the beginning.
If there is no God then… if atheism is true there is no ultimate standard so there can be no moral obligations or duties. In an atheistic worldview who or what lays such duties upon us? No one… Remember, for the atheist humans are just accidents of nature. Highly evolved animals but animals have **no moral obligations to one another.
** When a cat kills a mouse it hasn’t done anything morally wrong the cat is just being a cat. If an otter or a duck rapes and kills a female and has sex with its corpse. Has it done anything morally wrong? No, the duck and the otter are just being ducks and otters. If God doesn’t exist, we should view human behavior in the same way. No action should be considered morally right or wrong.
So, can evolution explain morality? That is what you are really suggesting. First of all Moral laws are not chemical or biological; they are immaterial and come from personal agents. If there is no God there is no such thing as a “law”. Secondly Chemistry and biology are descriptive not prescriptive; evolution describes what does survive. Not what ought to survive. Survival of the fittest?
That’s exactly what Hitler believed in That’s why he was trying to get rid of the unfit because the unfit were taking resources away from the fit
If survival is all that matters… Should we rape to survive? If survival is our goal then maybe we ought to rape. We could propagate our DNA by raping right? Many species in the animal kingdom do propagate via rape. Why not us? You can rape and survive that way. You don’t need consent if there is no objective morality. Also, should we murder the weak to survive? That’s Hitler’s point.
Consistency demands then that you would say that homosexuality is immoral. After all it doesn’t do anything to help us survive. If all people adopted it… It would be the end of humanity’s survival within 100 years. So… therefore it’s immoral? I’m sure you have heard of Theists referring to the “Natural Law”. Glad to see you and I agree on one thing.
