Watts' art was an effort to invest his own age, an age of reason, with the nobilities engendered in an age of faith. At the time Watts was at his prime his contemporaries were everywhere losing belief in the spiritual conceptions of earlier periods; they were analyzing everything, and were deciding that what was really true in religion, what gave it nobility, was its ethical teaching; retain that, and religion might go, illustrating the truth of the Chinese philosopher who said: "When the spirit is lost, men follow after charity and duty to one's neighbors." The unity of belief was broken up into diverse intellectual conceptions. Men talked about love and liberty, patriotism, duty, charity, and a whole host of abstractions moral and intellectual, which they had convinced themselves were the essence of religion and the real cause of its power over man. Whether Watts lost faith like his contemporaries I do not know, but their spirit infected his art. He set himself to paint these abstractions; and because we cannot imagine these abstractions with a form, we feel something fundamentally false in this side of his art. He who paints a man, an angelic being, or a divine being, paints something we feel may have life. But it is impossible to imagine Time with a body as it is to imagine a painting embodying Newton's law of gravitation. It is because such abstractions do not readily take shape that Watts drew so much on the imaginative tradition of his predecessors. Where these pictures are impressive is where the artist slipped by his conscious aim, and laid hold of the nobility peculiar to the men and women he used as symbols. It is not Time or Death which awes us in Watts' picture, but majestical images of humanity; and Watts is at his greatest as an inventor when humanity itself most occupies him when he depicts human life only, and lets it suggest its own natural infinity, as in those images of the lovers drifting through the Inferno, with whom every passion is burnt out and exhausted but the love through which they fell.
