The American founders, many of them, validated their political cause and secession from Britain by resorting to natural law theories and paradigms.[i] Thomas Jefferson memorialized these theories and paradigms in the Declaration of Independence.[ii] While studying nature and the physical world, Jefferson extended natural law jurisprudence while revising it to fit the needs and settings of the New World.[iii] Rather than looking to divine or moral prescription to ground his natural law theories, Jefferson looked to nature. He borrowed from Newtonian ideas about the laws of the universe and applied them to the laws of man.[iv] A human law was, by this logic, akin to the law of gravity.
The American insistence on natural law was a reaction to the analytical positivism gaining credence in Britain.[v] This school of jurisprudence found its fullest expression in the utilitarianism of Jeremy Bentham and John Austin. These men treated laws as linguistic constructs: commands that attained the status of law because people followed them, not because they reflected a priori or transcendent rules of the cosmos. American founders such as Jefferson saw natural law as a way to distinguish themselves from their British counterparts and to define what it meant to be American. William Blackstone, one of the few British jurists still clinging to natural law principles,[vi] enjoyed vast success from American purchases of Commentaries on the Laws of England.[vii] The popularity of this treatise in America had to do with Blackstone’s support for ideals that, from the colonials’ perspective, affirmed Revolutionary rhetoric and philosophical principles.[viii] Blackstone died in 1780. His death ushered in the age of positive law jurisprudence in England.[ix]
In America, however, natural law picked up momentum in the wake of the Revolution and American independence.[x] That ideas of natural law flourished during the Enlightenment, especially in America where institutions were supposed to reflect—indeed embody—Enlightenment principles, is curious because the Enlightenment glorified reason and humanism: progressive concepts seemingly incongruous with a moral theory derived from ancient church teachings and philosophical orthodoxies. This disjuncture reveals the extent to which colonials sought to divorce their culture and communities from the British. Á la Blackstone, colonials would go great lengths to “prove” their natural law theories through application of the scientific method and appeals to reason.[xi] Natural law jurisprudence did, in fact, fit within a scientific and rational framework in many important respects. For instance, natural law, like laws of the natural world putatively discoverable by reason, logic, and experiment, were by definition universal. Just as truths about the external world allegedly were deduced through sustained study of specimens and species, so truths about the human condition were, natural theorists argued, deduced through sustained study of human behavior and the history of the races.[xii] In this sense, colonial jurists viewed natural law not as retrograde, superstitious, or religious, but as cutting-edge and scientific. Americans were not alone in their attention to the scientific elements of law. In Western and Central Europe during the mid-to-late eighteenth century, rulers and leaders “sought to rationalize their legal systems, to make law scientific, to extend it in a vernacular language evenly over their territories, and to put an end to the earlier jumble of customs, privileges, and local rights.”[xiii] Save for Blackstone’s efforts, however, this scientific trend did not gain much traction in England.[xiv]
Early Americans, particularly northerners[xv] but also Virginians such as Jefferson and George Mason, celebrated the ideals of natural law and natural rights appearing in the Declaration, but they found those ideals difficult to implement in everyday practice. Although staunchly committed to the principles of natural law, the colonials, at least those with representation or voice in the political sphere, discovered that abstract philosophy did not readily translate into workaday rules and regulations.[xvi] “It was one thing,” submits David Brion Davis, “to state abstract propositions, and quite another to decide how the law applied to a particular case.”[xvii] Above all, the “peculiar institution” of American slavery called into question the Enlightenment values upon which American natural law jurisprudence depended. Cries of freedom and liberty rang hollow once Americans were no longer up against an oppressive British Empire. These cries began to sound hypocritical—if they did not seem so already—as the institution of slavery became a mainstay of the economy of the fledgling nation.[xviii] How could colonists extol freedom, liberty, and equality yet enslave masses of people? This American philosophical “inconsistency pinched harder when slaves began to speak the language of natural rights.”[xix] As Samuel Johnson, the eminent British Tory and man of letters, quipped, “How is it that we hear the loudest yelps for liberty among the drivers of negroes?”[xx]

[ii] “[T]he argument of the Declaration is a subtle, if ambiguous, blending of empirical historical analysis and the metaphysics of Natural Law. To prove its central contention—that the revolution was made necessary by British policies—the document enumerates twenty-seven specific events in recent history which reveal precisely how Britain acted to establish despotism. […] But the revolutionaries meant to transcend arguments of expediency, for such arguments were always subject to the vicissitudes of opinion and opinion might lead one to conclude that a revolution was in fact unnecessary and therefore unjustifiable. To remove their claims from the arena of opinion and to ground them with certainty, the revolutionaries felt constrained to found the argument for justification on the principle of Natural Rights which was rooted in the theory of Natural Law as applied to politics and society. Thus the grievances enumerated in the Declaration, weighty in themselves for some readers, were for others concrete examples of how one nation attempted to subordinate another to an ‘absolute despotism.’ The grievances, taken together, demonstrated that British policies had violated the fundamental principles of Natural Law itself.” Lester H. Cohen, “The American Revolution and Natural Law Theory,” Journal of the History of Ideas, Vol. 39, No. 3 (1978) at 491-92.

See also David Brion Davis, The Problem of Slavery in the Age of Revolution, 1770-1823 (Ithaca and London: Cornell University Press, 1975) at 343-385. Davis explains this English phenomenon as follows: “In England there was no ‘fundamental shift in values’ that mobilized the society into revolution. There was no counterpart to the American need for self-justification. No new hopes or obligations arose from an attempt to build a virtuous republic. Such phrases as ‘created equal,’ ‘inalienable rights,’ and ‘the pursuit of happiness’—all of which appeared in classic liberal texts—were qualified by a reverent constitutionalism that looked to Saxon precedent to legitimize ideals of freedom. The notion of man’s inherent rights, when assimilated to the historical concept of British ‘liberty,’ implied little challenge to traditional laws and authorities. And by the 1790s the very idea of inherent rights was giving way to radical and conservative forms Utilitarianism.” Davis, The Problem of Slavery in the Age of Revolution at 343.
[vi] In short, Blackstone believed that the common law reflected natural law principles and that any law contradicting natural law was invalid. Consider, e.g., the following quotation: “This law of nature, being co-eval with mankind and dictated by God himself, is of course superior in obligation to any other. It is binding all over the globe, in all countries, and at all times: no human laws are of any validity, if contrary to this; and such of them as are valid derive all their force, and all their authority, mediately or immediately, from this original. […] Upon these two foundations, the law of nature and the law of revelation, depend all human laws; that is to say, no human laws should be suffered to contradict these.” Sir William Blackstone, Commentaries on the Laws of England, Book I at 41-42.

[ix] The jurisprudential split between Blackstone and Bentham, while stark, was not as hostile as some first considered: “Until recently Bentham’s claim to have made a sharp break with Blackstone has won wide acceptance, and that fact, combined with Bentham’s ascendancy, was chiefly responsible for consigning Blackstone to obscurity. […] No doubt this outcome resulted in part from Bentham’s mastery of invective, and in part from the fact that the elderly Blackstone did not deign to notice the attacks of an upstart critic, much less reply to them. Even the strongest partisans of Bentham have conceded that much of his criticism directed at Blackstone was misplaced[…]. In spite of Bentham’s efforts, most historians of the relationship have acknowledged that Bentham, despite his implacable hostility, combined relentless criticism with passages of praise that became as famous as some of his barbs.” Richard A. Cosgrove, Scholars of the Law: English Jurisprudence from Blackstone to Hart (New York University Press, 1996) at 52.

[xi] “[Blackstone] presented law as a science, a ‘rational science,’ that included an extensive discussion of natural law. To Blackstone, the principles of natural law are universal and superior to positive law, including the common law. […] Natural law, according to Blackstone, is either revealed by God or discoverable through human reason. […] American jurisprudents readily accepted Blackstone’s natural law orientation. […] [N]atural law provided a convenient and useful justification for the adoption of English common law in the various states of the burgeoning nation. Especially in the decades following soon after the Revolutionary War, if the common law had been understood merely as an English institution distinctive to Britain itself, then an American reliance on the common law would have seemed impolitic or even treasonous. If, however, the common law arose from universal principles of the law of nature, which were revealed by God or discovered through human reason, then the common law would be legitimate everywhere, including in America.” Stephen M. Feldman, “From Premodern to Modern American Jurisprudence: The Onset of Positivism,” 50 Vanderbilt Law Review 1387 (1997) at 1396-97.
[xii] Thomas R. R. Cobb, a jurist from Georgia and an expert on slave laws, took pains to show how science validated the idea of slaves as naturally inferior and in need of white supervision. Consider this quote by Cobb: “The history of the negro race then confirms the conclusion to which an inquiry into the negro character had brought us: that a state of bondage, so far from doing violence to the law of his nature, develops and perfects it; and that, in that state, he enjoys the greatest amount of happiness, and arrives at the greatest degree of perfection of which his nature is capable. And, consequently, that negro slaver, as it exists in the United States, is not contrary to the law of nature.” Thomas R. R. Cobb, An Inquiry into the Law of Negro Slavery in the United States of America (Philadelphia: T. & J. W. Johnson & Co., 1858) at 51.
