Context

“The notion of Virtue cannot be considered vague or unsettled, because a man may find it difficult to explain the notion fully to himself, or to expound it to others in such a way as to prevent cavilling. Virtue is a whole, and no more consists of parts than man's intelligence does; and yet we speak of various intellectual faculties as a convenient way of expressing the various powers which man's intellect shows by his works. In the same way we may speak of various virtues or parts of virtue, in a practical sense, for the purpose of showing what particular virtues we ought to practice in order to the exercise of the whole of virtue, that is, as man's nature is capable of.” source
