But there is more still present here than just this appearance, namely: (a) the cause acts upon the passive substance, alters its determination; but this determination is its positedness, for otherwise there is nothing else to alter; the other determination which it obtains is however that of causality; the passive substance thus comes to be cause, power, and activity; (b) the effect is posited in it by the cause; but that which is posited by the cause is the cause itself which, in acting, is identical with itself; it is this cause that posits itself in the place of the passive substance.
