=20.= A similar difficulty confronts us when we ask whether the deity of the Stoics is to be considered as personal. All the terms commonly used in association with a personal deity are adopted by the Stoics: their god is Lord and Father. But then they use with equal freedom terms commonly associated with materialism: for the Supreme Being is to them body or stuff, a primitive fire which converts itself by natural laws into every form of being. For this reason the Stoics are commonly called materialists, and yet the main body of their teaching is contrary to that usually associated with materialism[52]. Further, beside the personal and the material conceptions of the Deity, they adopted and developed a conception which exercised an extraordinary influence over other systems, when they attributed the exercise of all the powers of deity to the divine Word, which from one point of view is the deity himself, and from another is something which emanates from him and is in some way distinct. Thus the term ‘God,’ which to children and child-like religions appears so simple, is in the Stoic system extraordinarily complex; and its full content cannot be grasped without a willingness to revise the meaning of many conceptions which seem firmly established, such as those of personality, material, and quality. If we are to suppose that the Stoic conception of the Word arose ultimately from similar conceptions in Hebraism or Persism, by which the voice of a personal God attained to a quasi-independent personality, we must allow that the Stoics made use of this term with a boldness and consistency which from the time of their appearance brought it into the forefront of religious and metaphysical controversy. Through the Stoics the doctrine of the Word passed into the systems of Judaism and Christianity, to perform in each the like service by reconciling doctrines apparently contradictory. Of all the systems we may perhaps say that Stoicism makes the fewest new assertions or negations, but introduces the most numerous interpretations. [Sidenote: Influence of Stoicism.]
