considered in its own nature it seems absolutely free and unfettered. So, then, there are two necessities--one simple, as that men are necessarily mortal; the other conditioned, as that, if you know that someone is walking, he must necessarily be walking. For that which is known cannot indeed be otherwise than as it is known to be, and yet this fact by no means carries with it that other simple necessity. For the former necessity is not imposed by the thing's own proper nature, but by the addition of a condition. No necessity compels one who is voluntarily walking to go forward, although it is necessary for him to go forward at the moment of walking. In the same way, then, if Providence sees anything as present, that must necessarily be, though it is bound by no necessity of nature. Now, God views as present those coming events which happen of free will. These, accordingly, from the standpoint of the Divine vision are made necessary conditionally on the Divine cognizance; viewed, however, in themselves, they desist not from the absolute freedom naturally theirs. Accordingly, without doubt, all things will come to pass which God foreknows as about to happen, but of these certain proceed of free will; and though these happen, yet by the fact of their existence they do not lose their proper nature, in virtue of which before they happened it was really possible that they might not have come to pass. 'What difference, then, does the denial of necessity make, since, through their being conditioned by Divine knowledge, they come to pass as if they were in all respects under the compulsion of necessity? This difference, surely, which we saw in the case of the instances I formerly took, the sun's rising and the man's walking; which at the moment of their occurrence could not but be taking place, and yet one of them before it took place was necessarily obliged to be, while the other was not so at all. So likewise the things which to God are present without doubt exist, but some of them come from the necessity of things, others from the power of the agent. Quite rightly, then, have we said that these things are necessary if viewed from the standpoint of the Divine knowledge; but if they are considered in themselves, they are free from the bonds of necessity, even as everything which is accessible to sense, regarded from the standpoint of Thought, is universal, but viewed in its own nature particular. "But," thou wilt say, "if it is in my power to change my purpose, I shall make void providence, since I shall perchance change something which comes within its foreknowledge." My answer is: Thou canst indeed turn aside thy purpose; but since the truth of providence is ever at hand to see that thou canst, and whether thou dost, and whither thou turnest thyself, thou canst not avoid the Divine foreknowledge, even as thou canst not escape the sight of a present spectator, although of thy free will thou turn thyself to various actions.
