Force Field, Space, Contour

A Force Field is constituted by an interplay of Repulsion and Attraction--the former opens it up, while the latter delimits the opening.  That interplay thus defines, a posteriori, the 'space' of a Force Field, independently of any a priori division of 'Space', qua form of outer appearances, as Kant's theory has it.  That independence is clear from his own example of a 'body' as a space-filling force, for, plainly a body 'fills a space' only by virtue of being a Force Field the contour of which is a product of its internal interplay of Repulsion and Attraction.
