I'm sorry, but I really do fail to see the need for a transcendent source.
It logical stands that if there are objective morals then there needs to be a transcendent source. This is simply because morality can only happen between humans yet humans are infallible as to being perfectly good and rational about what is best to do morally. So the source has to be humanlike yet beyond humans, be perfectly good, rational and necessary. That logically leads to a transcendent being. Theres a good arguement for this here
The moral argument
Premise 1: Morality is a rational enterprise
Premise 2: Moral realism is true, meaning moral facts and duties exist
Premise 3: The moral problems and disagreements among humans are too much for us to assume moral facts and duties are grounded in a human source of rationality.
Premise 4: Moral facts and duties are grounded in a necessary, rational source (from 1, 2, and 3)
Premise 5: this source is what we call God or a god or transcendent being.

PS remember we are assuming objective morals exist to argue the necessity of a transcendent source. If you want an arguemnet for objective morality (moral realism) there that can be found here

To me morality is simply our deep-seated predisposition toward socially beneficial behavior. Many social animals exhibit the exact same tendencies, but it's only us humans who possess both the desire and the capacity to try to explain them.
I think what your talking about is social behaviour which are different to morality. Social behaviour may involve things like etiquette or protocols
. A society may think chewing gum at the dinner table is inappropriate but that’s not morally wrong. Morality is different. It involves moral obligations, behaviour we should not do.
And historically, whatever we can't explain via natural means, we try to explain via supernatural ones. But in the case of morality no such supernatural explanation is required.
So luckily we have a rational and logiocal arguement to explain morality.
Morals exist simply because they make human societies possible. There are still gaps in our knowledge for a transcendent source to fill, but explaining the existence of morality isn't one of them.
As per the above logic arguement above a transcendent being as the basis for moral law is a logically argued conclusion. As I have saiid a few times now which you seem to ignore (you made a point of ignoring things) "Using survival, functioning, stability, making human societies possible are not objective foundations for morality.
These reasons are also determined subjectively by humans who are fallible when it comes to morality. Evolution is not a basis for morality either as what matters for survival is also subjectively determined by humans. Evolution itslef cannot explain why something is morlaly wrong. So all of these reasons are logical fallacies.
Remember, I'm an epistemological solipsist, so I can appreciate skepticism. But there's a point where skepticism turns into denial.
I think I can appreciate this view, a bit like the devil’s advocate as well.
For example, even if I question the nature of reality, I don't question the existence of reality.
This is an important point for moral realism. I agree we don’t question if our reality (physical world) is real. We just experience it, see it and sense it and process all that experience and determine we are justified to believe that what we see is real and not some computer simulation.
It is the same for morals. We experience moral situations, we test and process that moral experience and we intuitive know if somethings not right. So we are just as justified to believe what we see morally is also real. Just as justified about our intuition we experience of the physical world.
Neither do I question things such as the principle of sufficient reason, for if I question reason itself then what hope do I have of understanding anything? But reason tells me that if the world around me evolved, then morality probably evolved too.
I think the first conclusion
“if I question reason itself then what hope do I have of understanding anything?” makes logical sense. It’s sort of self-evident like the moral fact of the "Truth". You can’t find the truth if you question the truths worth.
But the second conclusion your reasonoing is faulty and I think it is a logical fallacy. Just because you reason the world evolved doesnt meran morals also evolved. Thats an unfounded assumption. In fact if there are objective morals then reasoning should logically lead you to a rational and necessary source of morality that is outside anything humans think including evolution.
As did the human need to invoke God. But I see no sense in invoking the supernatural where simply the natural will do.
Once again you using faulty reasoniong and assumptions that evolution explains morality. It may explain how we know morality but it doesnt explain why something is morally wrong.
I think I have also pointed this out several times but you seem to not be acknowledging this. I realize you tried to explain it but as above this was also insufficient support. You are creating an "ëither and or fallacy" as well. If we canniot explain morality then people must use God. But we have another option, logic and reason and that points to morality being based outside humans, and evolution.
As a solipsist I can appreciate the sentiment, but it's wrong to simply assume what the material world is and isn't capable of.
Actually I think it has been verified that abstract ideas like truth, justice etc. are non-physical and real human concepts. They can provoke a physical reaction but they are not a material thing, they are a thought, idea, abstract. But they have no physical form, like colour or Math.
What we refer to as "morality" may be nothing more than a fortuitous genetic adaptation, and our moral predispositions may have a purely physical cause.
Do you realise the implications of this. It would mean people could claim no responsibility for their behaviour as it was inherited genetically like diabeties.
But once again some people feel the need to invoke the supernatural to explain what they think the natural can't.
Like I said I agree that just invoking the supernatural is not enough to explain morality. Thats why there is a logical arguement that logically leads to there needing to be some source for morality beyond humans and evolution (natural processes). Ie morals are between people not natural processes, the basis for how we determine moral right and wrong has to be beyond any chance, arbitrary or random process like humans or evolution.
It absolutely does explain "Why" something is wrong, it's wrong because it leads to a dysfunctional society, and dysfunctional societies don't survive.
But this doesn't explain why something is morally right or wrong. It only explains how we know its wrong. Someone could then say "So why is a functional society or human survival a morally good thing. There is no basis for this either as its all subjective.
So evolution has instilled us with an intuitive sense of right and wrong. Then left it up to us to explain why we feel that way.
Because evolution and humans have no objective basis for accounting for why something is right or wrong it cannot matter or account for morality intuitively. Thats because what we would experience morally would be subjective and too inconsistent/contradictory to be a solid basis for intuition. To be a justified belief about something our intuitive experience needs to have an objective basis and evolution/humans are fallible and irrational.
For argument sake let’s say that morality is merely the product of evolution. The question still remains why we ought to behave in a way that will benefit the survival of our species. Whence does our moral obligation to do what is good for humans come?
Our nature can serve as a proximate foundation for such obligation. Since by nature we are ordered to do good and our nature determined that good for us. But without God as an ultimate source for that nature the dictates of our evolved nature ultimately wouldn’t express the intelligence or will of any rational being superior to humans. If that’s the case, we would have to say that which morally binds us is the by-product of random and chaotic non-rational process.
As Thomas Aquinas explains in his Summa Theologiae
Law is in ordinance of reason for the common good made by him who has care of the community and is imposed on others by way of a rule and measure. But this necessarily presupposes a being of intelligence and volition that can know the rule and impose it. Therefore, if the evolved order of human nature that determines what’s good for us is to be a law that morally binds us there must exist a being superior to humans who has intellect and will and ultimately has care over the human community. So unless someone is willing to say moral obligation doesn’t exist one should reject the idea that evolution is sufficient to explain morality.
Both math and morality are sets of descriptive laws. One set describes the rules by which reality functions, the other set describes the rules by which society functions, and evolution underpins both of them.
How can you say morality is a descriptive law. The fact there are moral duties involved with morality makes it proscriptive. Humans owe a moral duty to another human. Thats an obvious given if you understand ethics and morality.
Actually Math also proscribes a formula for somethung to work. So its also more than descriptive.
