his grandson, and his great-grandson, that is, the fourth generation. By the mention of this attribute we are, as it were, told that His commandments, undoubtedly in harmony with His acts, include the death even of the little children of idolaters because of the sin of their fathers and grandfathers. This principle we find frequently applied in the Law, as, e.g., we read concerning the city that has been led astray to idolatry, “destroy it utterly, and all that is therein” (Deut. xiii. 15). All this has been ordained in order that every vestige of that which would lead to great injury should be blotted out, as we have explained. We have gone too far away from the subject of this chapter, but we have shown why it has been considered sufficient to mention only these (thirteen) out of all His acts; namely, because they are required for the good government of a country; for the chief aim of man should be to make himself, as far as possible, similar to God: that is to say, to make his acts similar to the acts of God, or as our Sages expressed it in explaining the verse, “Ye shall be holy” (Lev. xxi. 2): “He is gracious, so be you also gracious; He is merciful, so be you also merciful.” The principal object of this chapter was to show that all attributes ascribed to God are attributes of His acts, and do not imply that God has any qualities. CHAPTER LV We have already, on several occasions, shown in this treatise that everything that implies corporeality or passiveness, is to be negatived in reference to God, for all passiveness implies change; and the agent producing that state is undoubtedly different from the object affected by it; and if God could be affected in any way whatever, another being beside Him would act on Him and cause change in Him. All kinds of non-existence must likewise be negatived in reference to Him; no perfection whatever can therefore be imagined to be at one time absent from Him, and at another present in Him: for if this were the case, He would [at a certain time] only be potentially perfect. Potentiality always implies non-existence, and when anything has to pass from potentiality into reality, another thing that exists in reality is required to effect that transition. Hence it follows that all perfections must really exist in God, and none of them must in any way be a mere potentiality. Another thing likewise to be denied in reference to God, is similarity to any existing being. This has been generally accepted, and is also mentioned in the books of the Prophets; e.g., “To whom, then, will you liken me?” (Isa. xl. 25); “To whom, then, will you liken God?” (ib. 18); “There is none like unto Thee” (Jer. x. 6). Instances of this kind are frequent. In short, it is necessary to demonstrate by proof that nothing can be predicated of God that implies any of the following four things: corporeality, emotion or change, non-existence,—e.g., that something would be potential at one
