But since those rational natures, which we have said above were made in the beginning, were created when they did not previously exist, in consequence of this very fact of their nonexistence and commencement of being, are they necessarily changeable and mutable; since whatever power was in their substance was not in it by nature, but was the result of the goodness of their Maker. What they are, therefore, is neither their own nor endures for ever, but is bestowed by God. For it did not always exist; and everything which is a gift may also be taken away, and disappear. And a reason for removal will consist in the movements of souls not being conducted according to right and propriety. For the Creator gave, as an indulgence to the understandings created by Him, the power of free and voluntary action, by which the good that was in them might become their own, being preserved by the exertion of their own will; but slothfulness, and a dislike of labour in preserving what is good, and an aversion to and a neglect of better things, furnished the beginning of a departure from goodness. But to depart from good is nothing else than to be made bad. For it is certain that to want goodness is to be wicked. Whence it happens that, in proportion as one falls away from goodness, in the same proportion does he become involved in wickedness. In which condition, according to its actions, each understanding, neglecting goodness either to a greater or more limited extent, was dragged into the opposite of good, which undoubtedly is evil. From which it appears that the Creator of all things admitted certain seeds and causes of variety and diversity, that He might create variety and diversity in proportion to the diversity of understandings, i.e., of rational creatures, which diversity they must be supposed to have conceived from that cause which we have mentioned above. And what we mean by variety and diversity is what we now wish to explain.
