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[1] Whether moral virtue observes the mean?

A[2] Whether the mean of moral virtue is the real mean or the rational mean?

A[3] Whether the intellectual virtues observe the mean?

A[4] Whether the theological virtues do?
