Atomism had no absolute 'above' and 'below' and no such rulers, so favoured the undersranding of justice as an agreement amongst equals.

Moral claims aren't, as a class, truth-value apt or not.

Epicurus recommends bread and cheese as the staple, and his emphasis is more on avoiding pain than on seeking pleasure, insofar as pleasure-seeking tends to be followed by painful after-effects.

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.

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.

Morality has in the past made progress when we broadened the category of things we weren't permitted to harm (animals, 'infidels'); saw through some delusions and rationalisations about what harms are good for people themselves (prison punishment, hysterectomies for unhappy 1950s wives); and readjusted our for-the-good of others criteria so as to demand only reasonable sacrifices (ceasing to use children as handy chimney sweeps).

For the chemists, who wanted to manufacture new medicines and elixirs and transform base substances into noble ones, the notion that there was no metaphysical barrier to doing so - it was just a matter of getting the particles into new arrangements - was encouraging. That was the Baconian programme.
