I don't see how being a faster runner, or a better mathematician makes you 'deserve' access to a better life, or more influence on policy, in the absence of a social decision to play that game in the way it's proposed to be organised for some set of benefits.

We call 'Slavery is wrong' a moral truth because there is a specific history of theoretical investigation of a particular kind of slavery. We discussed it for centuries in metaphysical, economic, biological, and philosophical terms; we listened to all the arguments pro and con, we read all the testimonies of slaves and witnesses, and we decided. Though this 'we" is not everybody on earth, or even most people, who've never thought about slavery much.

Epicurus was in favour of friendly sex but not of grand passions or marriage and children, viewing them as sources of trouble and vexation.

We are now returning to the 18th century empirical approach with the new interest in the evolutionary basis of ethics, with 'experimental' moral philosophy and moral psychology. As a result, we understand better why moral formulas are experienced as ineluctable commands, even if there is no commander and even if the notion of an inescapable obligation is just superstition. So moral philosophy has made huge progress.

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.

Some critics thought the ontology and theory of qualities absurd. No one had ever seen these little atoms, and furthermore, how could their mere arrangement produce a noisy, colourful, world in which day followed night and animals generated their own kind? Instead of a world created, cared, for and supervised by supernatural persons, the Epicureans appeared to the theologians to be assigning everything to chance. The latter were appalled by Lucretius's view of religion as cruel and oppressive and by the Epicurean insistence that death is the end of all experience.

People should be able to develop their abilities and interests and have access to such goods as friendship, artistry, and nature and a political voice. It's possible to be poor and yet have all this, but in a polarized society, and one where culture and adventure have been thoroughly monetised, it is a lot more difficult.
