Sometimes again we have
recourse to quality, as in the question, “What is
rhetoric? Is it the power to persuade or the science
of speaking well?” This form of question is of
frequent occurrence in the courts. For instance, the
question may arise whether a man caught in a
brothel with another man's wife is an adulterer.
Here there is no doubt about the name; it is the
significance of the act which is in doubt, since the
question is whether he has committed any sin at all.
For if he has sinned, his sin can only be adultery.
