 It should be noted that More’s Spirit of Nature must be extended in space, if it can be said to emanate spherically. This marks More’s notion of spirit out from Descartes’s res cogitans. For Descartes, matter is extended and souls are not; strictly speaking (although there was some room for manoeuvre, Reid 2008), souls are non-spatial entities and do not exist in space. For More, this is an idea of existence which makes no sense. For something to exist, it must exist somewhere; it must occupy space. The same is true of God, no less than the Spirit of Nature, and individual souls (Reid 2003, Leech 2013).
