But what they are ignorant of the facts of states-of-affairs that are going on inside their own brain and the brains of the 7+ billion of humans at present.
Morality is not about looking for facts outside one brain.
Morality and Ethics is about doing good which is avoiding what is evil [moral nor religious sense]
Morality and moral facts are confined to the mental states of the individuals, thus;
- P1 All mental states are facts
P2 All moral states are mental states
C1 All moral states are facts, i.e. moral facts.
Thus the moral fact 'all humans ought-not to kill another' is a mental state within each human being.
DNA/RNA wise all humans are "programmed" with the mental states of the potential to kill so as to enable them to kill animals for food and in self-defense. But such a potential is double-edged as it could possibly facilitate the killing of all humans.
As such all humans are also "programmed" with an inherent inhibitory mental states of ought-not to kill [unless necessary] within a moral faculty, framework and system.
All moral facts are reducible to non-moral properties. All moral facts are reducible and represented by various neural algorithms within the brain of all humans as evident in the brains of the 7+ billion of humans in the present and of those in the past.
Therefore moral facts exist.
This is indisputable.
