Thoughts of Frederick Douglass on finding the trajectory of moral and social justice in the course of history.

There is, in the world’s government, a force which has in all ages been recognized, sometimes as Nemesis, sometimes as the judgment of God and sometimes as retributive justice; but under whatever name, all history attests the wisdom and beneficence of its chastisements, and men become reconciled to the agents through whom it operates, and have extolled them as heroes, benefactors and demigods.

To the broad vision of a true philosophy, nothing in this world stands alone. Everything is a necessary part of everything else. The margin of chance is narrowed by every extension of reason and knowledge, and nothing comes unbidden to the feast of human experience. The universe, of which we are a part, is continually proving itself a stupendous whole, a system of law and order, eternal and perfect. Every seed bears fruit after its kind, and nothing is reaped which was not sowed. The distance between seed time and harvest, in the moral world, may not be quite so well defined or as clearly intelligible as in the physical, but there is a seed time, and there is a harvest time, and though ages may intervene, and neither he who ploughed nor he who sowed may reap in person, yet the harvest nevertheless will surely come, and as in the physical world there are century plants, so it may be in the moral world, and their fruitage is as certain in the one as in the other. The bloody harvest of Harper’s Ferry was ripened by the heat and moisture of merciless bondage of more than two hundred years. That startling cry of alarm on the banks of the Potomac was but the answering back of the avenging angel to the midnight invasions of Christian slave-traders on the sleeping hamlets of Africa. The history of the African slave-trade furnishes many illustrations far more cruel and bloody.

Viewed thus broadly our subject is worthy of thoughtful and dispassionate consideration. It invites the study of the poet, scholar, philosopher and statesman. What the masters in natural science have done for man in the physical world, the masters of social science may yet do for him in the moral world. Science now tells us when storms are in the sky, and when and where their violence will be most felt. Why may we not yet know with equal certainty when storms are in the moral sky, and how to avoid their desolating force?
