God is the One. He gives forms to all things, and is himself all things. God alone is the real existent, all else is an existent by virtue of him. Unity is the symbol of God because in number also the unit is the foundation of all number, and yet is not itself number. It exists by virtue of itself and needs not the numbers that come after. At the same time the unit is also all number, because all number is made up of the unit. God alone is one, because he alone is not composed of matter and form, as everything else is. God has neither likeness nor form, for he is the creator of all things, _i. e._, of all likeness and form. He is therefore incorporeal. In God the subject knowing and the object of his knowledge are one and the same thing. Else he would not be one. In knowing himself, therefore, he knows the universe. God as the cause and creator of all things must know all things, the universal as well as the particular, the world soul as well as the various species, and even every single creature, but he knows the particular in a general way. For God knows only what is permanent, whereas the particular is constantly changing, hence he does not know the particular as such, but only as involved in the general and permanent. As God is incorporeal he is not subject to corporeal accidents or human feelings. Hence the many expressions in the Bible which ascribe such accidents and feelings to God must be understood as metaphors. It is a psychological necessity for man wishing to communicate his ideas to other men to speak in human terms, whether he speak of beings and things inferior or superior to him. The result is that the metaphor he finds it necessary to employ either raises or lowers the object to which it refers. It elevates the sub-human and lowers the superhuman to the human. This is the explanation of such phrases as "the mouth of the earth" the "hand of the Jordan," the "head of the dust of the world," and so on, in which the figure is that of personification. And the fundamental explanation is the same in such phrases as "The Lord repented," "The Lord rested," "The Lord remembered," "He that dwelleth in heaven laughs," and so on, where the process is the reverse of personification. The motive common to both is to convey some idea to the reader.
