Now, against the sacrilegious and impious darings of reason, we assert both that God knows all things before they come to pass, and that we do by our free will whatsoever we know and feel to be done by us only because we will it. But that all things come to pass by fate, we do not say; nay we affirm that nothing comes to pass by fate; for we demonstrate that the name of fate, as it is wont to be used by those who speak of fate, meaning thereby the position of the stars at the time of each one's conception or birth, is an unmeaning word, for astrology itself is a delusion. But an order of causes in which the highest efficiency is attributed to the will of God, we neither deny nor do we designate it by the name of fate, unless, perhaps, we may understand fate to mean that which is spoken, deriving it from _fari_, to speak; for we cannot deny that it is written in the sacred Scriptures, "God hath spoken once; these two things have I heard, that power belongeth unto God. Also unto Thee, O God, belongeth mercy: for Thou wilt render unto every man according to his works."[192] Now the expression, "Once hath He spoken," is to be understood as meaning "_immovably_," that is, unchangeably hath He spoken, inasmuch as He knows unchangeably all things which shall be, and all things which He will do. We might, then, use the word fate in the sense it bears when derived from _fari_, to speak, had it not already come to be understood in another sense, into which I am unwilling that the hearts of men should unconsciously slide. But it does not follow that, though there is for God a certain order of all causes, there must therefore be nothing depending on the free exercise of our own wills, for our wills themselves are included in that order of causes which is certain to God, and is embraced by His foreknowledge, for human wills are also causes of human actions; and He who foreknew all the causes of things would certainly among those causes not have been ignorant of our wills. For even that very concession which Cicero himself makes is enough to refute him in this argument. For what does it help him to say that nothing takes place without a cause, but that every cause is not fatal, there being a fortuitous cause, a natural cause, and a voluntary cause? It is sufficient that he confesses that whatever happens must be preceded by a cause. For we say that those causes which are called fortuitous are not a mere name for the absence of causes, but are only latent, and we attribute them either to the will of the true God, or to that of spirits of some kind or other. And as to natural causes, we by no means separate them from the will of Him who is the author and framer of all nature. But now as to voluntary causes. They are referable either to God, or to angels, or to men, or to animals of whatever description, if indeed those instinctive movements of animals devoid of reason, by which, in accordance with their own nature, they seek
