PRIMARY AND SECONDARY EVIL FOR THE SOUL.
5. Since the lack of good is the cause that the soul looks at darkness, and mingles therewith, the lack of good and darkness is primary Evil for the soul. The secondary evil will be the darkness, and the nature of evil, considered not in matter, but before matter. Evil consists not in the lack of any particular thing, but of everything in general. Nothing is evil merely because it lacks a little of being good; its nature might still be perfect. But what, like matter, lacks good entirely, is essentially evil, and possesses nothing good? Nature, indeed, does not possess essence, or it would participate in the good; only by verbal similarity can we say that matter "is," while we can truly say that matter "is" absolute "nonentity." A mere lack (of good) therefore, may be characterized as not being good; but complete lack is evil; while a lack of medium intensity consists in the possibility of falling into evil, and is already an evil. Evil, therefore, is not any particular evil, as injustice, or any special vice; evil is that which is not yet anything of that, being nothing definite. Injustice and the other vices must be considered as kinds of evil, distinguished from each other by mere accidents; as for instance, what occurs by malice. Besides, the different kinds of evil differ among each other either by the matter in which evil resides, or by the parts of the soul to which it refers, as sight, desire, and passion.
