tually. Nor can anything which is of necessity exist potentially; yet these things are primary; for if these did not exist, nothing would exist. Nor does eternal movement,Rebel Waxed Bunda, if there be such, exist potentially; and, if there is an eternal mobile,Arjen Robben Drakt, it is not in motion in virtue of a potentiality,Duvetica Ženy Ace Quattro, except in respect of ‘whence’ and ‘whither’ (there is nothing to prevent its having matter which makes it capable of movement in various directions). And so the sun and the stars and the whole heaven are ever active,Celtic Drakt, and there is no fear that they may sometime stand still, as the natural philosophers fear they may. Nor do they tire in this activity; for movement is not for them,Moncler Edward, as it is for perishable things,AC Milan Drakt Damer, connected with the potentiality for opposites, so that the continuity of the movement should be laborious; for it is that kind of substance which is matter and potency, not actuality,Męskie Barbour Quilted Kurtka, that causes this.
Imperishable things are imitated by those that are involved in change, e.g. earth and fire. For these also are ever active; for they have their movement of themselves and in themselves. But the other potencies, according to our previous discussion,NBA Drakter, are all potencies for opposites; for that which can move another in this way can also move it not in this way,Mexico Drakt Barn, i.e. if it acts according to a rational formula; and the same non-rational potencies will produce opposite results by their presence or absence.
If, then, there are any entities or substances such as the dialecticians say the Ideas are, there must be something much more scientific than science-itself and something more mobile than movement-itself; for these will be more of the nature of actualities, while science-itself and movement-itself are potencies for these.
Obviously, then, actuality is prior both to potency and to every principle of change.
Book IX Chapter 9
That the actuality is also better and more valuable than the good potency is evident from the following argument. Everything of which we say that it can do something, is alike capable of contraries, e.g. that of which we say that it can be well is the same as that which can be ill,Parajumpers Männer Maine Eco, and has both potencies at once; for the same potency is a potency of health and illness, of rest and motion, of building and throwing down, of being built and being thrown down. The capacity for contraries, then, is present at the same time; but contraries cannot be present at the same time, and the actualities also cannot be present at the same time, e.g. health and illness. Therefore, while the good must be one of them, the capacity is both alike,Mexico Drakt, or neither; the actuality, then, is better. Also in the case of bad things the end or actuality must be worse than the potency; for that which ‘can’ is both contraries alike. Clearly,Muži Barbour Waxed Bunda, then, the bad does not exist apart from bad things; for the bad is in its nature posterior to the potency. And therefore we may also say that in the things which are from the beginning, i.e. in eternal things, there is nothing bad, nothing defective, nothing perverted (for perversion
