t produces movement through infinite time,Belstaff Muži Bunda, but nothing finite has infinite power; and, while every magnitude is either infinite or finite,White Caps FC Drakt, it cannot,Parajumpers Damen Juliet Jacken Schweiz, for the above reason,Muži Barbour Cranwell Bunda, have finite magnitude, and it cannot have infinite magnitude because there is no infinite magnitude at all). But it has also been shown that it is impassive and unalterable; for all the other changes are posterior to change of place.
Book XII Chapter 8
It is clear, then,Moncler Aliso, why these things are as they are. But we must not ignore the question whether we have to suppose one such substance or more than one, and if the latter,Parajumpers Muži UGO, how many; we must also mention, regarding the opinions expressed by others, that they have said nothing about the number of the substances that can even be clearly stated. For the theory of Ideas has no special discussion of the subject; for those who speak of Ideas say the Ideas are numbers,Moncler Gene, and they speak of numbers now as unlimited, now as limited by the number 10; but as for the reason why there should be just so many numbers, nothing is said with any demonstrative exactness. We however must discuss the subject, starting from the presuppositions and distinctions we have mentioned. The first principle or primary being is not movable either in itself or accidentally, but produces the primary eternal and single movement. But since that which is moved must be moved by something, and the first mover must be in itself unmovable, and eternal movement must be produced by something eternal and a single movement by a single thing, and since we see that besides the simple spatial movement of the universe, which we say the first and unmovable substance produces,Parajumpers Muži Squirrel, there are other spatial movements-those of the planets-which are eternal (for a body which moves in a circle is eternal and unresting; we have proved these points in the physical treatises), each of these movements also must be caused by a substance both unmovable in itself and eternal. For the nature of the stars is eternal just because it is a certain kind of substance, and the mover is eternal and prior to the moved, and that which is prior to a substance must be a substance. Evidently, then,Canada Goose Heli, there must be substances which are of the same number as the movements of the stars,UGG Ansley Czyścibut 5775, and in their nature eternal, and in themselves unmovable,Parajumpers Muži Kodiak, and without magnitude, for the reason before mentioned. That the movers are substances, then, and that one of these is first and another second according to the same order as the movements of the stars, is evident. But in the number of the movements we reach a problem which must be treated from the standpoint of that one of the mathematical sciences which is most akin to philosophy-viz. of astronomy; for this science speculates about substance which is perceptible but eternal,Děti Moncler Vesta, but the other mathematical sciences, i.e. arithmetic and geometry, treat of no substance. That the movements are more numerous than the bodies that are moved is evident to those who have given even moderate attention to the matter; for each of the planets has more than one mo
