Of course, it also fits in perfectly well with a non-religious worldview.
Not really. The non religious worldview is that morality is subjective and relative to culture. But being born with morals is not subjective or relative to culture. It implies that there are certain core morals that we can hold all people to regardless of subjective opinions or relative culture.
It fixes moral laws as objectives that stand regardless. But how can we say that morals are like a law, a physical law ehen they are not physical themselves. Thus if there are some non physical laws like morality then there must be some source for this. They don't come out of thin air. This at least points to some higher power that causes these laws to exist.
If anything morality is best understood by religion ratrher than some worldview that cannot explain this.
Behaviour is something that can be selected for by evolution - just look at beavers and their instinctive need to build dams, even when there are no suitable damn building materials. The behaviour is just as much a part of them as their fur thickness, or any other physical trait.
Yes but the behaviour to build dams was first non genetic. It was something creatures worked out. It can change generation to generation. It just so happens that the beavers behaviour happened to provide a benefit some the entire ecosystem is passed on and not the genetics for it. It becomes instinctual later after generations have adopted these behaviours.
Its the same for humans. If we are in cold climates we can adapt and that social behaviour is passed on. But if for some reason things suddenly changed then humans can create a completely different environment and adapt again. Showing that the behaviour is not genetic but something beyond. Such as a rational mind or innate knowledge of nature. Which is of 'Mind' and not a material process like genes and mutations.
This relates to the 'Hard Problem of Consciousness'.
And so Humans, as a species that tends to live in large and complex social groups, would also find that behavioural characteristics are selected for by evolution. Those behaviours that are beneficial are selected for, and those that are harmful are selected against.
I disagree. Evidence shows its not selected by evolution (as if evolution can select). But rather its selected by humans, by the creature itself based on their ability to work this out and an innate knowledge of nature. It is the human who chose to build enviornments that were more conducive for survival.
It was humans who chose or rather dicovered certain moral truth were more conducive for a better life. They could chose otherwise which they have and opposed these moral truths. But nevertheless they chose them and they can change if they choose to change them. Which shows that morals are not a physical process that gets fixed by genetics.
So behaviours that are harmful, such as violence, murder, aggression, etc tend to be selected against. The behaviours that are beneficial, such as helping others who are in pain, etc, are selected for.
But they are not selected against by genes and mutations. They are consciously selected. They can change from generation to generation. We have just seen a change from Christain morals to secular Woke ideology in a generation.
Isn't it plausible that these common behaviours are the basis for our naturalistic morality?
The thing is though we are born with an innate sense of morality culture can and does orientate this sense towards different ideas and beliefs about what this moral sense is and how it should be applied.
So we could end up with what some cultures believe is immoral all being cultivated at the same time and yet all claiming to be based on our innate sense of morality. We are back to subjective and relative morality.
We believe that it is morally right to help others because this kind of behaviour is one that, due to its benefit to the social groups Humans live in, is one that has been repeatedly selected for by evolution, and is now genetically encoded in us in just the same way that our eye colour or hair colour is?
The Vikings raped and pillaged and this was very successful for them for a long time. They became powerful. Under this logic of evolution whatever behaviour is of benefit for the group is moral. The conquering vikings who bring back hoards for the group and benefiting the group.
In fact, I would argue that this is a BETTER explanation than your "God gave us morality" worldview.
As morality is not something that can be explained by material processes it points to an immaterial source. It makes sense that some moral lawgiver be it God or gods or some spirital force made these moral laws as they are about moral behaviour and not something inanimate.
Pinning morals on some physical process of beneficial behaviour could mean anything. Whatever behaviour people feel is good under the circumstances. Thats not a good basis for morality.
I think morality needs a transcedent moral lawgiver who is above fallible humans and who is perfectly good and justified to be the creator and judge of moral behaviour. Otherwise its just a matter of opinion.
After all, if your argument is correct, we should all have the SAME view on morality. And yet this is not the case. Sure, it is generally the same in the broad strokes - don't kill, don't steal -
That is basically all the law. Morality is primarily about how we treat others. What else is there that doesn't stem from not killing or stealing. Not killing also implies all the harms done up to killing. Not stealing can cover a braod range from stealing someone time by not doing what your paid for. To stealing posessions or someones wife.
It is these core morals researchers have found are the same for all cultures. They mention courage. So the opposite of killing someone is saving someones life. That is the moral value of courage.
but what about other cases? Is it morally acceptable to smack a child? Is the death penalty morally acceptable? There is a lot of disagreement about these ideas, and that simply would not be the case if there was a single objectively correct morality.
These are the factual aspects that may different for the same moral truth. The moral related to smacking children is "don't abuse children'. Everyone agrees on that. Its just that the facts may vary ie some cite evidence smacking is ok and others that its not.
There will always be a truth to be found. But sometimes that truth is not yet found but most of the time its denied. So just because there is disagreement doesn't mean there is a moral truth to be found. The very natuire of morality demands a truth as its about a right way and a wrong way to behave. There is no middle ground.
There is, after all, no disagreement about other things where there is a single objectively correct point of view, such as the Pythagorean theorem.
Well actually there is. Take the 'Flat Earthers' for example. What about biologocal sex. These are denied as objective facts.
This broad similarity but variations on a small scale fits perfectly with what we would expect from something that was a result of evolution, in just the same way that my hair is blonde and my husband's hair is black, but all human hair is somewhere on the brown side of things. We don't see people with naturally green hair, after all. It's always some shade of a brownish colour, whether it be light like mine, or dark like my husband's.
Yes but morality is a different kind of phenomena to the physical aspects of humans like genetic hair color. Its overlayed on this with a belief system whicch cannot be reduced to physical aspects. So humans can color their hair green and this becomes their reality, the reality for the group. They can believe a man can become a women and that trumps biological reality because their belief trumps physical reality.
If God is the God of morality and the physical world then moral truths should be in alignment with all aspects of reality. So just as God said He made man and women in His image this aligns with biological reality. Even though the moral law is not in itself a physical law.
