Whether evil is in good as in its subject?

❌ Objection 1 : It would seem that evil is not in good as its subject. For good is something that exists. But Dionysius says (Div. Nom. iv, 4) that "evil does not exist, nor is it in that which exists." Therefore, evil is not in good as its subject.

❌ Objection 2 : Further, evil is not a being; whereas good is a being. But "non-being" does not require being as its subject. Therefore, neither does evil require good as its subject.

❌ Objection 3 : Further, one contrary is not the subject of another. But good and evil are contraries. Therefore, evil is not in good as in its subject.

❌ Objection 4 : Further, the subject of whiteness is called white. Therefore also the subject of evil is evil. If, therefore, evil is in good as in its subject, it follows that good is evil, against what is said (Is. 5:20): "Woe to you who call evil good, and good evil!"
