Fourthly. A thing is described by its relation to another thing, e.g., to time, to space, or to a different individual; thus we say, Zaid, the father of A, or the partner of B, or who dwells at a certain place, or who lived at a stated time. This kind of attribute does not necessarily imply plurality or change in the essence of the object described; for the same Zaid, to whom reference is made, is the partner of Amru, the father of Becr, the master of Khalid, the friend of Zaid, dwells in a certain house, and was born in a certain year. Such relations are not the essence of a thing, nor are they so intimately connected with it as qualities. At first thought, it would seem that they may be employed in reference to God, but after careful and thorough consideration we are convinced of their inadmissibility. It is quite clear that there is no relation between God and time or space. For time is an accident connected with motion, in so far as the latter includes the relation of anteriority and posteriority, and is expressed by number, as is explained in books devoted to this subject; and since motion is one of the conditions to which only material bodies are subject, and God is immaterial, there can be no relation between Him and time. Similarly there is no relation between Him and space. But what we have to investigate and to examine is this: whether some real relation exists between God and any of the substances created by Him, by which He could be described? That there is no correlation between Him and any of His creatures can easily be seen; for the characteristic of two objects correlative to each other is the equality of their reciprocal relation. Now, as God has absolute existence, while all other beings have only possible existence, as we shall show, there consequently cannot be any correlation [between God and His creatures]. That a certain kind of relation does exist between them is by some considered possible, but wrongly. It is impossible to imagine a relation between intellect and sight, although, as we believe, the same kind of existence is common to both; how, then, could a relation be imagined between any creature and God, who has nothing in common with any other being; for even the term existence is applied to Him and other things, according to our opinion, only by way of pure homonymity. Consequently there is no relation whatever between Him and any other being. For whenever we speak of a relation between two things, these belong to the same kind; but when two things belong to different kinds though of the same class, there is no relation between them. We therefore do not say, this red compared with that green, is more, or less, or equally intense, although both belong to the same class—colour; when they belong to two different classes, there does not appear to exist any relation between them, not even to a man of ordinary intellect, although the two things belong to the same category; e.g., between a hundred cubits and the heat of
