A Dissertation on the Numbers of Mankind in antient and modern Times: in which The superior Populousness of Antiquity is maintained. With An Appendix, Containing Additional Observations on the same Subject, And Some Remarks on Mr. Hume's Political Discourse, Of the Populousness of antient Nations.

First edition, an important influence on the demographic work of both David Hume and Thomas Malthus. Robert Wallace (1697-1771) was an interesting figure in the Scottish Enlightenment, a founding member of the Rankenian Club during his university days and also active in the Philosophical and Select societies. His elaborate history of population was based on the extensive research in ancient history that he had originally presented to the Philosophical Society some time before 1745. Wallace opened his argument with a hypothetical model for the geometrical rate of world population growth, indicating that present world population was far below its potential. As Wallace was completing work on the Dissertation in 1751 he showed it to fellow Philosophical Society member David Hume, who reciprocated with the essay he published in the Political Discourses of 1752: "Of the populousness of ancient nations". Hume argued that population estimates in ancient sources were unlikely to be as accurate as modern assessments, but he graciously acknowledged his debt to Wallace, to which Wallace replied in the lengthy appendix here. "This polite exchange was widely celebrated as a model for the pursuit of truth in an enlightened age. Montesquieu supervised the translation of both works into French. In the Confessions Rousseau acknowledged the spirit of the debate, praising Hume in particular for having helped edit Wallace's text" (ODNB). Wallace's emphasis on the geometrical rate of population growth was a direct influence on Thomas Malthus's population calculus in the Essay on the Principle of Population. Hazlitt, in The Spirit of the Age, asserted that "both the principle of the necessary increase of the population beyond the means of subsistence, and the application of that principle as a final obstacle to all Utopian perfectibility schemes, are borrowed by Mr. Malthus from Wallace's work". In the preface to the second edition of the Essay, Malthus names Wallace among the four authors who led him to the population question. This copy has an interesting political provenance, with the bookplate of John Bond (1823-1828). Bond was from a long-established Dorset parliamentary family, and was Member for Corfe Castle.
