“From what can "ought" be derived. The most compelling answer is this: ethics must be somehow based on an appreciation of human nature — on a sense of what a human being is or might be, and on what a human being might want to have or want to be. If that is naturalism, then naturalism is no fallacy. No one could seriously deny that ethics is responsive to such facts about human nature. We may just disagree about where to look for the most compelling facts about human nature -n novels, in religious texts, in psychological experiments, in biological or anthropological investigations. The fallacy is not naturalism but, rather, any simple-minded attempt to rush from facts to values. In other words, the fallacy is greedy reductionism of values to facts, rather than reductionism considered more circumspectly, as the attempt to unify our world-view so that out ethical principles don't clash irrationally with the way the world is.”

Context: The equality of mankind is best understood in light of a two-fold inequality. The first is the inequality of mankind and of the subhuman classes of living beings that comprise the order of nature. Dogs and horses, for example, are naturally subservient to human beings. But no human being is naturally subservient to another human being. No human being has a right to rule another without the other's consent. The second is the inequality of man and God. As God's creatures, we owe unconditional obedience to His will. By that very fact however we do not owe such obedience to anyone else. Legitimate political authority—the right of one human being to require obedience of another human being—arises only from consent. The fundamental act of consent is, as the 1780 Massachusetts Bill of Rights states, "a social compact by which the whole people covenants with each citizen and each citizen with the whole people that all shall be governed by certain laws for the common good." The "certain laws for the common good" have no other purpose but to preserve and protect the rights that each citizen possesses prior to government, rights with which he or she has been "endowed by their Creator." The rights that governments exist to secure are not the gift of government. They originate in God.
