l88 The consequences of the

change of state is effected in matter, it mustbe by an external principle determining it,or by the internal determination of volition:or, that it cannot be without one of these,or some third way. But it is as good as al-ready proved, that matter cannot be enduedwith the power of volition. It was shewnbefore, N° 19. of this, that spontaneous mo-tion is effected byvolition; spontaneous mo-tion is the fame as voluntary motion. NoWnothing needs be more evident than that,since to effect motion is absolutely above thepower of matter, the power that ejf’eSls motionis absolutely above matter. Or take it thus,matter as a solid substance necessarily resistsall change of state; therefore it is incapableof being endued with that power that couldchange its slate : If it were capable of beingendued with this power, we should be ob-liged to deny its resistance; and therefore itsmoment, (N° 2 2. sect. 1.) as also its solid ex-tension (N°26.) In short, it is as incapableof being the subject in which this power andresistance can at once reside, as of being th®subject in which resistance and its contrarycan at once reside. Matter therefore is in-capable of all kind of activity, qr of being
