 Contrast this view of space with those of Descartes and of Newton. Both Descartes and Newton claim that space is a real, mind-independent entity; for Descartes it is matter, and for Newton a ‘pseudo-substance’, distinct from matter. And of course for both, these views are intimately tied up with their accounts of motion. Leibniz simply denies the mind-independent reality of space, and this too is bound up with his views concerning  motion.[10]
