The first loss a man suffers who does not study and investigate is that he does not understand the real existence of God, and imagines he is worshipping a body. Some think God is light. But this is as bad as to regard him body. For light is an accident in a shining body, as is proved by the fact that the air receives the light of the sun, and later it receives the shadow and becomes dark. And yet these people are not the worst by any means, for there are others who do not trouble to concentrate their minds on God, and occupy their thoughts solely with the business and the pleasures of this world. These people we do not discuss at all. We are arguing against those who imagine they are wise men and students of the Kalam. In fact they are ignorant persons, and do not know what logic is and how it is to be used. Before giving our own views of the nature and existence of God, we must refute the objectionable doctrines of these people. Joseph al-Basir in a work of his called "Mansuri" casts it up to the Rabbanites that in believing that God descends and ascends they are not true worshippers of God. But he forgets that his own doctrines are no better. Anyone who believes that God created with a newly created will and rejects by means of a newly created rejection has never truly served God or known him. Just as objectionable is their view that God is living but not with life residing in a subject, powerful but not with power, and so on. We shall take up each of these in turn. The Mutakallimun refuse to believe that God's will is eternal, for fear of having a second eternal beside God. And so they say that whenever God wills, he creates a will for the purpose, and whenever he rejects anything he creates a "rejection" with which the objectionable thing is rejected. But this leads them to a worse predicament than the one from which they wish to escape, as we shall see. If God cannot create anything without having a will as the instrument in creating, and for this reason must first create a will for the purpose--how did he create this will? He must have had another will to create this will, and a third will to create the second, and so on _ad infinitum_, which is absurd. If he created the first will without the help of another will, why not create the things he wanted outright without any will? Besides, in making God will at a given time after a state of not willing, they introduce change in God.
