The soul of pathos, like that of wit, is brevity. Very few writers are sufficiently aware of this. Humour is cumulative and diffusive, as Shakespeare, Rabelais, and Dickens well knew; but how many a good piece of pathos has been spoiled by the historian of Little Nell by an attempt to make too much of it! A drop of citric acid will give poignancy to a feast; but a draught of it----! Hence it is doubtful whether an English eye ever shed a tear over the _Vita Nuova_, whatever an Italian may have done. Next to the patient endurance of heroism, the bewilderment of weakness is the most fruitful source of pathos. Hence the exquisitely touching points in _A Pair of Blue Eyes_, _Two on a Tower_, _The Trumpet-Major_, and other of Hardy’s novels. Pathos is the luxury of grief, and when it ceases to be other than a keen-edged pleasure it ceases to be pathos. Hence Tennyson’s question in “Love and Duty,” “Shall sharpest pathos blight us?” involves a misunderstanding of the word; although his understanding of the thing is well proved by such lyrics as “Tears, idle tears,” and “O well for the fisherman’s boy.” Pleasure and beauty--which may be said to be pleasure visible--are without their highest perfection if they are without a touch of pathos. This touch, indeed, accrues naturally to profound pleasure and to great beauty by the mere fact of the incongruity of their earthly surroundings and the sense of isolation, peril, and impermanence caused thereby. It is a doctrine of that inexhaustible and (except by Dante) almost unworked mine of poetry, Catholic theology, that the felicity of the angels and glorified saints and of God Himself would not be perfect without the edge of pathos, which it receives from the fall and reconciliation of man. Hence, on Holy Saturday the Church exclaims, “O felix culpa!” and hence “there is more joy in heaven over one sinner that repenteth than over ninety and nine righteous who need no repentance.” Sin, says St. Augustine, is the necessary shadow of heaven; and pardon, says some other, is the highest light of its beatitude.
