Abstract

Descartes rightly attacked the idea of space as extended nothing, but in inferring that space is an extended something, a substance, he overlooked the possibility that it is instead a system of relations. Even if it is a substance, it does not follow – as Descartes implied that it does – that “space” and “matter” are synonymous. It might instead be that space is a substantial container, portions of which can be colocated with bodies or that space is a substantial separator, portions of which flow into all locations where there are no bodies.
