The life-world of human and animal experience, with colours, tastes, solid objects, is a perceptual effect of massed atoms.

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.

Claims like 'Slavery is wrong' are not fully common-sensical, so they must be at least partly theoretical.

The Epicureans denied that the gods had created the world and also denied that they played any role in it.

Epicurus was not at all interested in what we would call the problems of mass society, and he thought civic politics was just trouble and to be avoided by the wise.

It used to be that nobody would really argue with a woman, because what she thought (unless it was by way of providing helpful comments about one's own work) just didn't matter.

Epicurus thought of justice as an agreement to prevent people harming and being harmed.
