For there be two necessities: the one simple, as that it is necessary for all men to be mortal; the other conditional, as if thou knowest that any man walketh, he must needs walk. For what a man knoweth cannot be otherwise than it is known. But this conditional draweth not with it that simple or absolute necessity. For this is not caused by the nature of the thing, but by the adding a condition. For no necessity maketh him to go that goeth of his own accord, although it be necessary that he goeth while he goeth. In like manner, if providence seeth anything present, that must needs be, although it hath no necessity of nature. But God beholdeth those future things, which proceed from free-will, present. These things, therefore, being referred to the divine sight are necessary by the condition of the divine knowledge, and, considered by themselves, they lose not absolute freedom of their own nature. Wherefore doubtless all those things come to pass which God foreknoweth shall come, but some of them proceed from free-will, which though they come to pass, yet do not, by coining into being, lose, since before they came to pass, they might also not have happened. But what importeth it that they are not necessary, since that by reason of the condition of the divine knowledge they come to pass in all respects as if they were necessary? It hath the same import as those things which I proposed a little before--the sun rising and the man going. While they are in doing, they cannot choose but be in doing; yet one of them was necessarily to be before it was, and the other not. Likewise those things which God hath present, will have doubtless a being, but some of them proceed from the necessity of things, other from the power of the doers. And therefore we said not without cause that these, if they be referred to God's knowledge, are necessary; and if they be considered by themselves, they are free from the bonds of necessity. As whatsoever is manifest to senses, if thou referrest it to reason, is universal; if thou considerest the things themselves, it is singular or particular. But thou wilt say, 'If it is in my power to change my purpose, shall I frustrate providence if I chance to alter those things which she foreknoweth?' I answer that thou mayest indeed change thy purpose, but because the truth of providence, being present, seeth that thou canst do so, and whether thou wilt do so or no, and what thou purposest anew, thou canst not avoid the divine foreknowledge, even as thou canst not avoid the sight of an eye which is present, although thou turnest thyself to divers actions by thy free-will.
