has therefore very justly exposed a Precept delivered by some Ancient Writers, That a Man should live with his Enemy in such a manner, as might leave him room to become his Friend; and with his Friend in such a manner, that if he became his Enemy, it should not be in his Power to hurt him. The first Part of this Rule, which regards our Behaviour towards an Enemy, is indeed very reasonable, as well as very prudential; but the latter Part of it which regards our Behaviour towards a Friend, savours more of Cunning than of Discretion, and would cut a Man off from the greatest Pleasures of Life, which are the Freedoms of Conversation with a Bosom Friend. Besides, that when a Friend is turned into an Enemy, and (as the Son of
Sirach
calls him) a Bewrayer of Secrets, the World is just enough to accuse the Perfidiousness of the Friend, rather than the Indiscretion of the Person who confided in him.
Discretion does not only shew it self in Words, but in all the Circumstances of Action; and is like an Under-Agent of Providence, to guide and direct us in the ordinary Concerns of Life.
There are many more shining Qualities in the Mind of Man, but there is none so useful as Discretion; it is this indeed which gives a Value to all the rest, which sets them at work in their proper Times and Places, and turns them to the Advantage of the Person who is possessed of them. Without it Learning is Pedantry, and Wit Impertinence; Virtue itself looks like Weakness; the best Parts only qualify a Man to be more sprightly in Errors, and active to his own Prejudice.
Nor does Discretion only make a Man the Master of his own Parts, but of other Mens. The discreet Man finds out the Talents of those he Converses with, and knows how to apply them to proper Uses. Accordingly if we look into particular Communities and Divisions of Men, we may observe that it is the discreet Man, not the Witty, nor the Learned, nor the Brave, who guides the Conversation, and gives Measures to the Society. A Man with great Talents, but void of Discretion, is like
Polyphemus
in the Fable, Strong and Blind, endued with an irresistible Force, which for want of Sight is of no Use to him.
