Chimpanzees do not murder members of their own group.
The dominant male steps in and stops all conflicts before they become serious. He enforces peace.
This is not a human invention.
There is a natural rule, developing in all social species where violence and murder within the group is prohibited, unless there are other overruling circumstances.
Why?
Because in-group murder decreases the survival probability of the entire group.
So murder is not immoral in nature - life needs to kill to survive, source of man’s first guilt when he develops self-consciousness - it becomes self-destrtuve for social species and for species that have adopted a cooperative survival and reproductive strategy. Pagans developed rituals around killing one’s enemies or even prey. They thanked it for tis sacrifice - does it sound familiar, imbecile? They honoured their enemies.
If one kills a potential mate before or after mating, this will not pass on his or her genes.
Yet, some species, like praying mantis the female consumes the male after mating. That’s an exception, only possible for the female.
Morality is that. A innate rule forcing self-control - overriding already evolved impulses. It is mind imposing control over the body.
Rules that increase cooperative effectiveness.
They require no god, no universal doctrine. But only to make them more threatening.
Another example…incest.
It is immoral not because of some divine rule but because it increases the possibility of unfit mutations to be passed on, and it develops unfit combinations of genes.
Why is paedophilia immoral?
Because it destroys what has yet to develop the natural means to make copulation tolerable, because copulation is an interventional act…it is aggressive and certain psychologies have to mature to make it tolerable, and because it takes advantage of what has no ability to choose…rationally; hasn’t fully developed his/her free-wil, his/her ability to judge and to choose from his/her options.
Most moral rules are based on natural consequences.
Ethics develop much later as addendums to facilitate the development of stable complex systems where individuals do not know each other, are of different families and then different tribes; exceeding the number of relationships a human mind can maintain.
To integrate males and females that would be excluded from the gene-pool and so invest them in the welfare of the group. individuals that would remain un-invested in the welfare of the collective…disinterested and even disruptive.
To prevent thievery and appropriating another’s property to allow complex economics to develop.
No God giving Moses his commandments. That’s theater.
Do you understand?
No god required, other than to make the simple and those with no self-cotnrol to develop control - become civilized, i.e., cultivated.
Moral behaviour = genetic…innate to social species and those using heterosexual reproduction to pass on their genes, to overcome mortality.
Ethics = memetic…socioeconomic rules, accentuated by reward, fear enforced by a divine authority - fear of god - to force the average moron to abide by group norms, and group objectives, ideals.
