Originating in the first instance from practical life, Positivism will return thither with increased force, now that its long period of scientific preparation is accomplished, and that it has occupied the field of moral truth, which henceforth will be its principal domain. Its principle of sympathy, so far from relaxing our efforts, will stimulate all our faculties to universal activity by urging them onwards towards perfection of every kind. Scientific study of the natural Order is inculcated solely with the view of directing all the forces of Man and of Society to its improvement by artificial effort. Hitherto this aim has hardly been recognized, even with regard to the material world, and but a very small proportion of our energies has been spent upon it. Yet the aim is high, provided always that the view taken of human progress extend beyond its lower and more material stages. Our theoretical powers once concentrated on the moral problems which form their principal field, our practical energies will not fail to take the same direction, devoting themselves to that portion of the natural Order which is most imperfect, and at the time most modifiable. With these larger and more systematic views of human life, its best efforts will be given to the improvement of the mind, and still more to the improvement of the character and to the increase of affection and courage. Public and private life are now brought into close relation by the identity of their principal aim, which, being kept constantly in sight, ennobles every action in both. Practical questions must ever continue to preponderate, as before, over questions of theory; but this condition, so far from being adverse to speculative power, concentrates it upon the most difficult of all problems, the discovery of moral and social laws, our knowledge of which will never be fully adequate to our practical requirements. Mental and practical activity of this kind can never result in hardness of feeling. On the contrary, it impresses us more strongly with the conviction that Sympathy is not merely our highest happiness, but the most effectual of all our means of improvement; and that without it, all other means can be of little avail. Thus it is that in the Positive system, the Heart, the Intellect, and the Character mutually strengthen and develop one another, because each is systematically directed to the mode of action for which it is by nature adapted. Public and private life are brought into a far more harmonious relation than in any former time, because the purpose to which both are consecrated is identical; the difference being merely in the range of their activities. The aim in both is to secure, to the utmost possible extent, the victory of Social feeling over Self-love; and to this aim all our powers, whether of affection, thought, or action, are in both unceasingly directed.
