An important ethical problem which Judah Halevi discusses more thoroughly than any of his predecessors is that of free will, which he defends against fatalistic determinism, and endeavors to reconcile with divine causality and foreknowledge. We have already seen (p. xxi) that this was one of the important theses of the Mu'tazilite Kalam. And there is no doubt that fatalism is opposed to Judaism. A fatalistic determinist denies the category of the contingent or possible. He says not merely that an event is determined by its proximate cause, he goes further and maintains that it is determined long in advance of any of its secondary causes by the will of God. It would follow then that there is no way of preventing an event thus predetermined. If we take pains to avoid a misfortune fated to come upon us, our very efforts may carry us toward it and land us in its clutches. Literature is full of stories illustrating this belief, as for example the story of Œdipus. Against this form of belief Judah Halevi vindicates the reality of the contingent or possible as opposed to the necessary. No one except the obstinate and perverse denies the possible or contingent. His preparations to meet and avoid that which he hopes and fears prove that he believes the thing amenable to pains and precautions. If he had not this belief, he would fold his hands in resignation, never taking the trouble to supply himself with arms to meet his enemy, or with water to quench his thirst. To be sure, we may argue that whether one prepare himself or omit to do so, the preparation or neglect is itself determined. But this is no longer the same position as that maintained at the outset. For we now admit that secondary causes do play a part in determining the result, whereas we denied it at first. The will is one of these secondary causes. Accordingly Judah Halevi divides all acts or events into four classes, divine, natural, accidental and voluntary. Strictly divine events are the direct results of the divine will without any intermediate cause. There is no way of preparing for or avoiding these; not, that is, physically; but it is possible to prepare oneself mentally and morally, namely, through the secrets of the Torah to him who knows them.
Natural events are produced by secondary causes, which bring the objects of nature to their perfection. These produce their effects regularly and uniformly, provided there is no hindrance on the part
