schematisms

Updated: May 21, 2025

'Cohesions, said Chrysippus, 'are nothing else than airs, for it is by these that bodies are held together, and of the individual qualities of things which are held together by cohesion, it is the air which is the compressing cause which in iron is called "hardness", in stone "thickness" and in solver "whiteness". Not only solidarity then, but also colours, which Zeno called 'the first schematisms' of matter were regarded as due to the mysterious agency of air.
