the aspect of evil. Wherefore, since envy is sorrow for our neighbor's good, it follows that our neighbor's good becomes hateful to us, so that "out of envy cometh hatred."
Reply Obj. 1: Since the appetitive power, like the apprehensive power, reflects on its own acts, it follows that there is a kind of circular movement in the actions of the appetitive power. And so according to the first forward course of the appetitive movement, love gives rise to desire, whence follows pleasure when one has obtained what one desired. And since the very fact of taking pleasure in the good one loves is a kind of good, it follows that pleasure causes love. And in the same way sorrow causes hatred.
Reply Obj. 2: Love and hatred are essentially different, for the object of love is good, which flows from God to creatures, wherefore love is due to God in the first place, and to our neighbor afterwards. On the other hand, hatred is of evil, which has no place in God Himself, but only in His effects, for which reason it has been stated above (A. 1), that God is not an object of hatred, except in so far as He is considered in relation to His effects, and consequently hatred is directed to our neighbor before being directed to God. Therefore, since envy of our neighbor is the mother of hatred of our neighbor, it becomes, in consequence, the cause of hatred towards God.
Reply Obj. 3: Nothing prevents a thing arising from various causes in various respects, and accordingly hatred may arise both from anger and from envy. However it arises more directly from envy, which looks upon the very good of our neighbor as displeasing and therefore hateful, whereas hatred arises from anger by way of increase. For at first, through anger, we desire our neighbor's evil according to a certain measure, that is in so far as that evil has the aspect of vengeance: but afterwards, through the continuance of anger, man goes so far as absolutely to desire his neighbor's evil, which desire is part of hatred. Wherefore it is evident that hatred is caused by envy formally as regards the aspect of the object, but dispositively by anger.
QUESTION 35
OF SLOTH (In Four Articles)
We must now consider the vices opposed to the joy of charity. This joy is either about the Divine good, and then its contrary is sloth, or about our neighbor's good, and then its contrary is envy. Wherefore we must consider (1) Sloth and (2) Envy.
Under the first head there are four points of inquiry:
(1) Whether sloth is a sin?
(2) Whether it is a special vice?
(3) Whether it is a mortal sin?
(4) Whether it is a capital sin?
FIRST ARTICLE [II-II, Q. 35, Art. 1]
Whether Sloth Is a Sin?
Objection 1: It would seem that sloth is not a sin. For we are neither praised nor blamed for our passions, according to the Philosopher (Ethic. ii, 5). Now sloth is a passion, since it is a kind of sorrow, according to Damascene (De Fide Orth. ii, 14), and as we stated above (I-II, Q. 35, A. 8). Therefore sloth is not a sin.
Obj. 2: Further, no bodily failing that occurs at fixed times is a sin. But sloth is like this, for Cassian says (De Instit. Monast. x, [*De Institutione Caenobiorum]): "The monk is troubled with sloth chiefly about the sixth hour: it is like an intermittent fever, and inflicts the soul of the one it lays low with burning fires at regular and fixed intervals." Therefore sloth is not a sin.
