The admission that Massinger is moral must therefore be qualified by the statement that he is unnatural; or, in other words, that his morality is morbid. The groundwork of all the virtues, we are sometimes told, is strength. A strong nature may be wicked, but a weak one cannot attain any high moral level. The correlative doctrine in literature is, that the foundation of all excellence, artistic or moral, is a vivid perception of realities and a masculine grasp of facts. A man who has that essential quality will not blink the truths which we see illustrated every day around us. He will not represent vice as so ugly that it can have no charms, so foolish that it can never be plausible, or so unlucky that it can never be triumphant. The robust moralist admits that vice is often pleasant, and that wicked men flourish like a green bay-tree. He cannot be over-anxious to preach, for he feels that the intrinsic charm of high qualities can dispense with any artificial attempts to bolster them up by sham rhetoric, or to slur over the hard facts of life. He will describe Iago as impartially as Desdemona, and, having given us the facts, leave us to make what we please of them. It is the mark of a more sickly type of morality, that it must always be distorting the plain truth. It becomes sentimental, because it wishes to believe that what is pleasant must be true. It makes villains condemn themselves, because such a practice would save so much trouble to judges and moralists. Not appreciating the full force of passions, it allows the existence of grotesque and eccentric motives. It fancies that a little rhetoric will change the heart as well as the passing mood, and represents the claims of virtue as perceptible on the most superficial examination. The morality which requires such concessions becomes necessarily effeminate; it is unconsciously giving up its strongest position by implicitly admitting that the world in which virtue is possible is a very different one from our own.
