  Prophecy is another important issue in Ibn Daud’s thought, as it is the prophet who is the link between the heavenly world and man.  He is the person who—thanks to his specific knowledge—must guide man towards intellectual and moral perfection. Ibn Daud’s account of prophecy immediately follows his discussion of the intelligences, since it is the Active Intellect that plays a crucial role in the explanation of prophecy. This account has a twofold aim: firstly, to provide a rational explanation of the phenomenon of prophecy and, secondly, to defend the eternal validity of Mosaic Law against Christian and Muslim claims to the contrary. Ibn Daud is, however, not entirely consistent with regard to the first objective. He begins his exposition by following the Muslim philosophers in arguing that prophecy is a natural process that is related to dreams. Basing himself on his psychology, he explains how in certain circumstances someone can receive the overflow of the Active Intellect on his imaginative faculty and intellect by which he becomes a prophet. This goal can be pursued by people with a pure soul through study and association with good people. It would thus seem that anybody who meets certain requirements will automatically become a prophet. However, in a manner reminiscent of Judah Halevi, Ibn Daud then adds that the occurrence of this phenomenon is bound to certain conditions of place, time and nation. Clearly these stipulations are an attempt to safeguard the special character of biblical prophecy, but at the same time they impinge on the universalistic character of his psychological explanation of prophecy.
