For a newborn babe changes from its place to another place, for both of them belong to it; and though it comes from its own to its own [P. 42, l. 9.] it verily weeps when it goes forth,—how much more is an Entity [troubled] if a man roots it up from its place (and takes it) to another place which does not belong to it! For just as in its own Domain it is at peace, so in a Domain which is not its own it suffers calamity. Moreover, physicians say that everything which does not keep its nature ruins its natural generation, though they are speaking of custom and not of nature. For if a man goes to accustom himself to something to which he is not accustomed, if he does not wisely acquire the custom by stealth, little by little, he is injured by it. But if a thing to which a man is unaccustomed disables a man if he comes to it suddenly when it is natural even if it is not customary, how did the Darkness come upon the Light, its Opposite, suddenly [and enjoy it] ? And instead of what would have been right, (namely), that [P. 43.] it (i.e., the Darkness) should be positively injured as Nature indicates, it actually made an Assault upon it (i.e., the Light), as the Falsehood says, which against the Light. . . .
