When Science had expanded sufficiently to exist apart from Philosophy, it showed a rapid tendency towards a synthesis of its own, alike incompatible with metaphysics and with theology. It was late in appearing, because it required a long series of preliminary efforts: but as it approached completion, it gradually brought the Positive spirit to bear upon the organization of practical life, from which that spirit had originally emanated. But thoroughly to effect this result was impossible until the science of Sociology had been formed; and this was done by my discovery of the law of historical development. Henceforth all true men of science will rise to the higher dignity of philosophers, and by so doing will necessarily assume something of the sacerdotal character, because the final result to which their researches tend is the subordination of every subject of thought to the moral principle; a result which leads us at once to the acceptance of a complete and homogeneous synthesis. Thus the philosophers of the future become priests of Humanity, and their moral and intellectual influence will be far wider and more deeply rooted than that of any former priesthood. The primary condition of their spiritual authority is exclusion from political power, as a guarantee that theory and practice shall be systematically kept apart. A system in which the organs of counsel and those of command are never identical cannot possibly degenerate into any of the evils of theocracy. By entirely renouncing wealth and worldly position, and that not as individuals merely, but as a body, the priests of Humanity will occupy a position of unparalleled dignity. For with their moral influence they will combine what since the downfall of the old theocracies has always been separated from it, the influence of superiority in art and science. Reason, Imagination, and Feeling will be brought into unison: and so united will react strongly on the imperious conditions of practical life; bringing it into closer accordance with the laws of universal morality, from which it is so prone to deviate. And the influence of this new modifying power will be the greater that the synthesis on which it rests will have preceded and prepared the way for the social system of the future; whereas theology could not arrive at its central principle, until the time of its decline was approaching. All functions, then, that co-operate in the elevation of man will be regenerated by the Positive priesthood. Science, Poetry, Morality, will be devoted to the study, the praise, and the love of Humanity, in order that under their combined influence, our political action may be more unremittingly given to her service.
