By the supremacy of the Heart, the Intellect, so far from being crushed, is elevated; for all its powers are consecrated to the service of the social instincts, with the purpose of strengthening their influence and directing their employment. By accepting its subordination to Feeling, Reason adds to its own authority. To it we look for the revelation of the laws of nature, of the established Order which dictates the inevitable conditions of human life. The objective basis thus discovered for human effort reacts most beneficially on our moral nature. Forced as we are to accept it, it controls the fickleness to which our affections are liable, and acts as a direct stimulus to social sympathy. Concentrated on so high an office, the intellect will be preserved from useless digression; and will yet find a boundless field for its operations in the study of all the natural laws by which human destinies are affected, and especially those which relate to the constitution of man or of society. The fact that every subject is to be regarded from the sociological point of view, so far from discouraging even the most abstract order of speculations, adds to their logical coherence as well as to their moral value, by introducing the central principle round which alone they can be co-ordinated into a whole. And whilst Reason is admitted to its due share of influence on human life, Imagination is also strengthened and called into constant exercise. Henceforth it will assume its proper function, the idealization of truth. For the objective basis of our conceptions scientific investigation is necessary. But this basis once obtained, the constitution of our mind is far better adapted to esthetic than to scientific study, provided always that imagination never disregard the truths of science, and degenerate into extravagance. Subject to this condition, Positivism gives every encouragement to esthetic studies, being, as they are, so closely related to its guiding principle and to its practical aim, to Love namely, and to Progress. Art will enter largely into the social life of the Future, and will be regarded as the most pleasurable and most salutary exercise of our intellectual powers, because it leads them in the most direct manner to the culture and improvement of our moral nature.
