At the same time that I think discretion the most useful talent a man can be master of, I look upon cunning to be the accomplishment of little, mean, ungenerous minds.Discretion has large and extended views, and, like a well-formed eye, commands a whole horizon: cunning is a kind of short-sightedness, that discovers the minutest objects which are near at hand, but is not able to discern things at a distance. Discretion the more it is discovered, gives a greater authority to the person who possesses it: cunning, when it is once detected, loses its force, and makes a man incapable of bringing about even those events which he might have done had he passed only for a plain man.
Joseph Addison
