We must now consider the properties of virtues: and (1) the mean of virtue, (2) the connection between virtues, (3) equality of virtues, (4) the duration of virtues.
Under the first head there are four points of inquiry:
A Whether moral virtue observes the mean?
A Whether the mean of moral virtue is the real mean or the rational mean?
A Whether the intellectual virtues observe the mean?
A Whether the theological virtues do?
