Here, then, we may pause in our investigation and ask the conclusion. Have intellectual truths been more important in the past progress of the world than moral ones? Let us sum up. We have seen that the early ages of the world were dominated by the principle of unity; that during its career the moral agencies preponderated, while the intellectual were subordinated; that society, under the influence of these agencies, developed to a higher degree than subsequently certain elements, such as political order, national stability, religious sympathy, moral responsibility, associative labor, deference, reverence, and others, absolutely essential to the highest well-being of a nation; that these elements, however, in the absence of those of an opposite or counteracting nature, had a morbid rather than a healthful action, and kept humanity in darkness and stagnation, being inadequate to all the requirements of social progress; that a new development then began, under the impulse of a new and opposite principle, which evolved precisely those tendencies the want of which had prevented the complete realization of the highest purposes of national life; such were intellectual culture, political liberty, social equality, religious freedom and others; that in the course of the development of these principles, likewise absolutely necessary to the complete organization of community, those which had been predominant under the operation of the drift toward unity, became dormant; so that the results of the second stage of progression were, practically, the same as those of the first, namely, the evolution of magnificent principles, which in the absence of their counterparts had not a healthful action, and were unavailable for the establishment of the highest civilization; and finally, we have seen, from the nature of the two principles, that neither is adequate, alone, to the inauguration of a true social order, neither to develop the indispensable requisites which belong to its opposite, but that in every harmonious organization both must be present, mutually functioning, interblending, and expanding. This, then, is the answer: The moral agencies have tried to secure the highest social state without the aid of the intellectual, and have failed. The intellectual agencies have sought to secure the same object without the aid of the moral, and have likewise failed. There is no possibility of establishing the _desideratum_ without the full and uninterrupted play of the moral faculties; no possibility of establishing it without the full and uninterrupted play of the intellectual faculties; both have been equal factors in the history of the past in an isolated way; both will be equal factors in a blended harmony in the history of the future. One is humanity's head, and the other humanity's heart. With the absence of either the nation is not yet come into its birth; it is still an embryo.
