Published in 1765, the Commentaries became the definitive treatise on the common law in England and in America. According to Blackstone, the two foundations for law are nature and revelation through the Scriptures. Blackstone believed that the fear of the Lord was the beginning of wisdom, and thus taught that God was the source of all laws. It is interesting that even the humanist Rousseau noted in his Social Contract that one needs someone outside the world system to provide a moral basis for law. Unfortunately, our modern legal structure has been influenced by relativism and utilitarianism, instead of moral absolutes revealed in Scripture.
Relativism provides no secure basis for moral judgments.
There are no firm moral absolutes upon which to build a secure legal foundation. Utilitarianism looks merely at consequences and ignores moral principles. This legal foundation has been further eroded by the relatively recent phenomenon of sociological law. In this view, law should be based upon relative sociological standards. No discipline is more helpless without a moral foundation than law.
