These principles remain confined, therefore, within the same natural form of finitude; but although they do not wish to transcend the finite and, as regards appearances, lead only to finite causes that themselves demand further causes, they nonetheless equally expand themselves, partly into a formal totality in the concept of force, cause, or of such determinations of reflection that are supposed to signify originariness, and partly, through the medium of abstract universality, also into a sum total of forces, a whole of reciprocal causes.
