As to the test of Imagination when brought to bear upon human nature, you will remember, I dare say, that it was determined to be the success with which it “worked” human nature, or, in other words, made men do “what they are intended to do.” But I was then speaking of the way in which the great prophets, lawgivers, and founders of religions have influenced great masses of mankind, and in which almost every mother influences her children, by idealizing them. I might have added, and I will now add, a word on the manner in which an imaginary ideal of human nature proves its truth experimentally to the imaginer, by “working” _him_, that is, by making _him_ capable of doing “the work he was intended to do.” It is the more necessary to do this because the illusions of Imagination are nowhere so strong and so lasting as in the study of human Nature; and there is a danger that we may be deterred by the thought of them from steadily pursuing the truth. The cynic tells us with a sneer that babies, and none but babies, think men and women better than they are, and that, the older one grows, the more one is disillusionised about the virtue of human nature. But that is not true, or only a half truth. If we, as children, imagine the men and women about us to be perfections of power, wisdom, and virtue, one reason is, that we have, as children, a most inadequate standard of physical, mental, and moral excellence. As our standard rises, our sense of inadequacy increases; but the reason why, as we grow older, we cease to think people perfect, is, very often, not that we think worse of human beings, but that we think better of human possibilities. But in some minds defect of Imagination combines with other causes to induce the repeatedly disillusionised man to give up the search after the truth that lies beneath the illusion and to cast away all trust, all thought, of any ideal of humanity. Those who do this make shipwreck of their own lives. Their low ideal or no-ideal of conduct does not “work;” that is to say, it does not fit them to do the work they were intended to do. Even for the purposes of their own happiness their life is a failure. So far as the spiritual side of their nature is concerned, a dull and stagnant self-satisfaction is the highest prize they can hope to acquire: they have none of the keen joys of spiritual aspiration, of failures redeemed, of gradual progress, and of deeper insight into the glorious possibilities of human nature. But those who, while not rejecting the sobering admonitions of Experience and Reason, can nevertheless so far obey the promptings of Imagination as to retain in their hearts an ever fresh and expansive and healthful Ideal of life, find themselves led on by it from hope to nobler hope, from effort to more arduous effort, until life and effort end together.
