In his efforts to accomplish this object, the Positivist poet will naturally be led to form prophetic pictures of the regeneration of Man, viewed in every aspect that admits of being ideally represented. And this is the second service which Art will render to the cause of social renovation; or rather it is an extension of the first. Systematic formation of Utopias will in fact become habitual; on the distinct understanding that, as in every other branch of art, the ideal shall be kept in subordination to the real. The unlimited license which is apparently given to Utopias by the unsettled character of the time is in reality a bar to their practical influence, since even the wildest dreamers shrink from extravagance that oversteps the ordinary conditions of mental sanity. But when it is once understood that the sphere of Imagination is simply that of explaining and giving life to the conclusions of Reason, the severest thinkers will welcome its influence; because so far from obscuring truth, it will give greater distinctness to it than could be given by Science unassisted. Utopias have, then, their legitimate purpose, and Positivism will strongly encourage their formation. They form a class of poetry which, under sound sociological principles, will prove of material service in leading the people of the West towards the normal state. Each of the five modes of Art may participate in this salutary influence; each in its own way may give a foretaste of the beauty and greatness of the new life that is now offered to the individual, to the family, and to society.
