The essay investigates the proposition that economic questions are a fit subject for science. This investigation will involve a selective examination of seventeenth-century writings before looking at again selective Enlightenment texts. The essay is deliberately wide ranging, but it aims to pick out the emergence or crystallization of political economy by noting how theorists sought to establish it as a subject matter and in the process develop ways of studying it that aimed to uncover regularities and exhibit generality, systematicity, and precision. Together these supported its pretensions or claims to be a science that would in a Baconian manner be useful and free of the perceived shackles of a moralistic classical disparagement of economic activity.

2 Hume is sparing in his use of the term “oeconomy” in the volume (see Essays, 354, 383, 447). For his use of “political” for his title, compare Jean-Francois Melon, Essai Politique sur le Commerce (1735), Charles Dutot, Réflexions Politiques sur les Finances et le Commerce (1738). Hume knew and cited both works in the Political Discourses.

5 Ibid., 405. Compare in a clear “economic” context his observation, “ [the poorest artificer] expects that when he carries his goods to market and offers them at a reasonable price, he shall find purchasers and shall be able, by the money he acquires, to engage others to supply him with those commodities which are requisite for his subsistence. In proportion as men extend their dealings and render their intercourse with others more complicated, they always comprehend in their schemes of life a greater variety of voluntary actions which they expect, from the proper motives, to co-operate with their own,” Enquiries concerning Human Understanding and concerning the Principles of Morals, eds., L. A. Selby-Bigge and P. H. Nidditch (Oxford: Clarendon Press, 1975), 89 ( my emphases). Both this quotation and that from the Treatise are found in the sections on “Liberty and Necessity” where Hume is forthright in his assertions that human behavior is regular and uniform.

The use of “principles” is common (see, for example, Cary and Verri quoted above and its presence in the title of Steuart’s book as well as the subtitle of Condillac’s Commerce). The prestige of Newton’s Principia doubtless assisted its diffusion as is evident in Condillac’s definition in his Traité des Systèmes, “a system is more perfect when its principles are few in number: even better still when they are reduced to one” (Oeuvres I: 121). See Perrot, Histoire, 73, for a table of the rapidly increasing number of works published (in French) in the eighteenth century with système, principes, and théorie in their titles.
64 Richard Cantillon, Essai sur la nature du Commerce en général, ed. Stéphane Couvreur (Paris: Coppet, 2001 [1755]), 1. Condillac called the Essai one of the best works on the subject (Oeuvres II, 276 n). His influence can be seen in Beccaria, Mirabeau, Postlethwayt, and Smith, among many others.

66 William Petty, Preface to Political Arithmetic (1690) in Charles Hull, ed., Economic Writings of Sir William Petty, 2 volumes (Cambridge: Cambridge University Press, 1899), I: 244. Though the term “political arithmetic” appears in the title of several of Petty’s pamphlets, he nowhere else spells out what he means. A contemporary commenting on Petty’s Two Essays in Political Arithmetic (1687) upon their publication observed positively that he had “made it appear that Mathematical Reasoning is not only applicable to Line and Numbers but also affords the best means of Judging in all concerns of humane life” in Petty, Economic Writings, II, 513 n. Notwithstanding that observation, the apparent contrast between (implicitly) rhetoric and the objectivity of the quantifiable should not be overdrawn. See Ted McCormick, William Petty and the Ambitions of Political Arithmetic (Oxford: Oxford University Press, 2009), 10, cf. 303. Nonetheless McCormick (5) also summarizes the broad scholarly agreement that political arithmetic was a “methodological innovation that brought the quantitative techniques and empirical spirit of the Scientific Revolution to practical questions of economy, society and politics.” Paul Slack claims political arithmetic is “the most striking manifestation” of the “deliberate creation of political economy” (The Invention of Improvement [Oxford: Oxford University Press, 2015], 3, cf. 91).
67 Charles Davenant called Petty a “great genius” for beginning political arithmetic, which Davenant defined as “the art of reasoning by figures upon things relating to government.” However, he judged Petty to have built his calculations on false premises. Nonetheless, Davenant affirms, the “faculty of computing” is the way to give a true account of the balance of trade provided it “draws its conclusions from many premises.” Discourses on the Public Revenues and on Trade, in Charles Whitworth, ed., Works, 5 volumes (London, 1771), 1: 127, 129, 146, 149–150. But Cantillon upbraided both Petty and Davenant because as political arithmeticians they dealt only with effects, not causes and principles, Essai, 16. Smith would seem to agree (see below).

69 Mirabeau, L’Ami des Hommes (Amsterdam, 1759), Pt. 6: 2. François Quesnay especially stressed the mathematical basis; without calculation there would be no science, only confusion and error.
