Argument: I ask whether a holy thing and holiness, or a good thing and goodness, are the same?
Response: There is a great difference between concrete terms and abstract ones, as between a white thing and whiteness, between substance and accident. These are not synonyms, for a accident can either be present or absent.
On the contrary: Both a good thing and goodness are accidents, as are a man and humanity.
Response: As far as accidents are concerned, they are not synonomous.
