2. And now let us say something regarding those who maintain the existence of a diversity of spiritual natures, that we may avoid falling into the silly and impious fables of such as pretend that there is a diversity of spiritual natures both among heavenly existences and human souls, and for that reason allege that they were called into being by different creators; for while it seems, and is really, absurd that to one and the same creator should be ascribed the creation of different natures of rational beings, they are nevertheless ignorant of the cause of that diversity. For they say that it seems inconsistent for one and the same creator, without any existing ground of merit, to confer upon some beings the power of dominion, and to subject others again to authority; to bestow a principality upon some, and to render others subordinate to rulers. Which opinions indeed, in my judgment, are completely rejected by following out the reasoning explained above, and by which it was shown that the cause of the diversity and variety among these beings is due to their conduct, which has been marked either with greater earnestness or indifference, according to the goodness or badness of their nature, and not to any partiality on the part of the Disposer. But that this may more easily be shown to be the case with heavenly beings, let us borrow an illustration from what either has been done or is done among men, in order that from visible things we may, by way of consequence, behold also things invisible.
