Such a thing is envy, than which no worse evil can exist. For the adulterer indeed enjoys some pleasure, such as it is, and in a short time accomplishes his proper sin; but the envious man punishes himself, and takes vengeance upon himself more than on the person whom he envies, and never ceases from his sin, but is continually engaged in the commission thereof. For as a sow in mire, and evil spirits in our hurt, so also doth he delight in his neighbor’s ills; and if anything painful take place, then is he refreshed, and takes breath; accounting the calamities of others his own joys, and the blessings of others his own ills; and he considers not what pleasure may accrue to himself, but what pain to his neighbor. These men therefore were it not meet to stone and beat to death, like mad dogs, like destroying demons, like the very furies?
