But life is activity, the soul is a motive force, self-assertion and self-preservation are heaven's first law. Self-assertion, however, is nothing but the operation of communicated and committed animation, and self-preservation nothing but the postponement of the day of surrender. Self-preservation is impossible; self-assertion is a challenge to the assertiveness of other selves, as well as a hastener of dissolution. The self follows its native bent, and its native impulse is for expansion; but it thus, as a fraction, leaves, on its centrifugal path, the course of the great world spirit from which it separates; and as both a separate entity and a member of a community it must, in its attempt at self-realization, meet the constraint which the community, whose only object is likewise self-realization and self-preservation, puts upon all within its power. The law is negative and repressive, self-interest is positive and assertive; between the two there is no possible reconciliation--at most a compromise--so that in the last analysis it appears that the assertion of individual will as such is immoral, that is, contrary to the will of the community; and is sinful, for it is not the will of God, but the will of a particularized individual, however godly he may be. There are differences in degree, but not in kind, among immoralities and sins, with corresponding degrees of punitive repression; but the potential tragic conflict is constant, and there is as little doubt about the eminent domain of the State as about the supremacy of God. The laws of God are changeless and eternal, but human morality is a local and temporal development. As the character of an individual is the product of disposition and experience, so his fate is humanly determined by the particular forms of custom and law established in the community in which his lot is cast. But these change from time to time, and in periods of change the disparity between public and private interest is most conspicuous: the progressive individual bears not only the burden of proof but also the dead weight of public inertia. Only at infinity can the parallel antithetical interests coincide. Nevertheless, the world gradually effects self-correction by the evolution of new syntheses from the thesis and antithesis ever and anon presented for trial and judgment as between liberal and conservative forces.
