It is not persuasion, it is just the need for a decent company. If you want to have a decent wife for your strong son, then you will need a strong neighbor. Simple as that, and you will need some words to describe his strength, and that description is already virtue(s). And so you begin with it.
One needs to differ between voluntary morals (customs) and imposed (by religion).
Refusing to eat feces is a self-imposed law. Refusing to jump from heights is a self-imposed law. Refusing to stand, walk, dress and talk in a manner which is aesthetically unpleasant is a self-imposed law. Etc.
Your earlier statement can be changed to: “There is nothing voluntary about involuntary morality.”
You reserve the word morality for those moralities that are involuntary, whereas everything else, everything voluntary, is just a common sense or preferences.
My point is, social behavior and rules that define it are voluntary. In some people, of course. In others, in those who are afraid of being enslaved by it, this desire is denied, and so it appears to be something undesirable.
Haha, and how is it in a kingdom where the king says “I am the state”?
Why don’t you differ literate from illiterate people and confess that it is impossible to impose morality upon illiterate people who actually only have a periodical need to form a state for self-defense.
You see, people have lived for thousands of years voluntarily in illiterate communities and therefore we know nothing about their past, but we certainly know they had some morals. This morals are unconscious and voluntary.
You see, dueling was a custom in the wild west, and yet it was also a custom that everybody defends himself alone, so, the sheriff was the most immoral person and nobody wanted to be a sheriff. Learn your own history.
