Highly unequal societies are morally defective because they get to be that way through the exploitation by the clever and well-positioned ones of the vulnerabilities and weaknesses of others. The well-off then use their acquired political power to refuse to make sacrifices for others. This system brings us a wonderful range of products and experiences for consumers at the top of the privilege scale, but it also degrades and benumbs the workers at the lower end, as Adam Smith and Marx both said.

The moves to contractualism and utilitarianism required some extra ingredients besides mortalism, the denial that God is in charge of the world, and the doctrine that physical and psychological pain are the greatest evils.

In the old systems, hierarchies emanate power from above to below through forms of line management and are ideologically supported by cosmologies and theologies featuring celestial rulers and their deputies - the 'rule of the best.'

Moral theory develops from the divine command theory of medieval Christian philosophy, mixed up with a bit of ancient pagan virtue theory, to the purely secular moral sentiment and interpersonal reaction theories of Smith and Hume, to Kant's attempt to restore command theory but with something supersensible in the individual rather than God as the source of authority.

Aristotle saw nature as intelligent and purposive, whereas for the Epicureans, and the 17th century 'mechanical' philosophers, there is no intentionality in nature except where there are animal minds and bodies.

Human courtship has some wild extremes. At one end of the spectrum, there is harassment, pestering, blackmail, and an abuse of institutional power, which its targets rightly fear and loathe. At the other end is love, which as Nietzsche said, is beyond good and evil and always deserves our respect and compassion even when it is doomed or destructive. In the wide middle of the spectrum are all the ambiguous and tragi-comic goings-on of our species.

People's wants are not fixed; they generally want what others in their chosen comparison class appear to be enjoying and what advertising presents to them as attainable for them and as bringing happiness.
