  According to Crummell's Moral Principle Argument, just as the migration of populations is a fact of human life, occurring throughout human history, so too is the moral history of meaning and action that is built up around it. He takes this to be providential, not accidental. We may “discover evidences of a large and comprehensive plan, which excludes all ideas of the accidental or adventitious” (“Emigration, an Aid to the Civilization of Africa” [AA], 412). Human events in general accord with God's “grand moral economy” in which God is an “ever-active agent” (413). Crummell acknowledges that “our finite vision” often “fail[s] the discovery” of genuine moral ends. Consistent with his deontological understanding of moral obligation, as well as his realism about the moral, the effort to discover and examine moral ends by the reasoning agent is essentially an application of our mental faculties to scrutable moral problems, a mental task assigned by God. As the active, directing force and principle, the will of God “overrules all the deeds, the counsels, and the designs of men, and tracks them from their unseen germs, …to those manifest and notable deeds which rank among historic facts” (413).
