He is the freeman whom the truth makes free, And all are slaves besides. Who would have thought that we could glide so easily into so solemn a topic from looking at the quaint freaks of morning shadows? But the charm of the 'Task' is its sincerity; and in Cowper's mind the most trivial objects really are connected by subtle threads of association with the most solemn thoughts. He begins with mock heroics on the sofa, and ends with a glowing vision of the millennium. No dream of human perfectibility, but the expected advent of the true Ruler of the earth, is the relief to the palpable darkness of the existing world. The 'Winter Walk' traces the circle of thought through which his mind invariably revolves. It would be a waste of labour to draw out in definite formula the systems adopted, from emotional sympathy, rather than from any logical speculation, by Cowper and Rousseau. Each in some degree owed his power--though Rousseau in a far higher degree than Cowper--to his profound sensitiveness to the heavy burden of the time. Each of them felt like a personal grief, and exaggerated in a distempered imagination, the weariness and the forebodings more dimly present to contemporaries. In an age when old forms of government had grown rigid and obsolete, when the stiffened crust of society was beginning to heave with new throes, when ancient faiths had left mere husks of dead formulæ to cramp the minds of men, when even superficial observers were startled by vague omens of a coming crash, or expected some melodramatic regeneration of the world, it was perhaps not strange that two men, tottering on the verge of madness, should be amongst the most impressive prophets. The truth of Butler's speculation, that nations, like individuals, might go mad, was about to receive an apparent confirmation. Cowper, like Rousseau, might see the world through the distorting haze of a disordered fancy, but the world at large was itself strangely disordered, and the smouldering discontent of the inarticulate masses found an echo in their passionate utterances. Their voices were like the moan of a coming earthquake.
