Archibald Pitcairne’s medical writings are inspired by Newton’s Principia mathematica, as the Scottish physician assumed Newtonian physics as a model for scientific inquiry that should be applied to other branches of natural philosophy, including physiology and pathology. The ideal of a comprehensive mathematical science was very appealing to late seventeenth-century intellectuals, including physicians. This essay focuses on how Pitcairne tried to implement these ideas. In particular, I argue that Pitcairne’s medical thinking is based on three philosophical assumptions: first, a methodological (...) assumption, for which medical knowledge should be sought in the form of a deductive system; second, an epistemological assumption, that is, that our knowledge of physiological processes is sound only when we reduce them to a set of mathematical laws; and, third, an ontological assumption that identifies blood as the substance on which animal life most directly depends. I also suggest that such ideas should be studied against the backdrop of Pitcairne’s general mindset, including his personal sympathy for political conservativism. I further argue that his insistence on the reduction of natural processes to mathematical relations and his search for the universal order of nature also connect to his religious and political ideals.

It is a commonplace that the writers of eighteenth century Scotland played a key role in shaping the early practice of social science. This paper examines how this ‘Scottish’ contribution to the Enlightenment generation of social science was shaped by the fascination with unintended consequences. From Adam Smith's invisible hand to Hume's analysis of convention, through Ferguson's sociology, and Millar's discussion of rank, by way of Robertson's View of Progress, the concept of unintended consequences pervades the writing of the period. (...) The paper argues that the idea of unintended order shapes the understanding of the purpose of theoretical social science that emerges from the Scottish Enlightenment. (shrink)

This article examines the history of two fields of enquiry in late eighteenth- and early nineteenth-century Scotland: the rise and fall of the common sense school of philosophy and phrenology as presented in the works of George Combe. Although many previous historians have construed these histories as separate, indeed sometimes incommensurate, I propose that their paths were intertwined to a greater extent than has previously been given credit. The philosophy of common sense was a response to problems raised by Enlightenment (...) thinkers, particularly David Hume, and spurred a theory of the mind and its mode of study. In order to succeed, or even to be considered a rival of these established understandings, phrenologists adapted their arguments for the sake of engaging in philosophical dispute. I argue that this debate contributed to the relative success of these groups: phrenology as a well-known historical subject, common sense now largely forgotten. Moreover, this history seeks to question the place of phrenology within the sciences of mind in nineteenth-century Britain. (shrink)

Scholars have hitherto found little to no place for natural philosophy in the intellectual makeup of the Enlightened historian William Robertson, overlooking his significant contacts with that province and its central relevance to the controversy surrounding David Hume and Lord Kames in the 1750s. Here I reexamine Robertson's Situation of the World at the Time of Christ's Appearance (1755) in light of these contexts. I argue that his foundational sermon drew upon the scientific theism of such thinkers as Joseph Butler, (...) Edmund Law, and Colin Maclaurin to counter the autonomous figurations of the universe associated with Hume and Kames, and to develop a historical account of progress based around Christian progressivism rather than the stadial theory of Adam Smith. Robertson conceived of history neither in secular terms nor in those of traditional religion, but sought instead to update the language of providentialism by naturalizing the sacred within a framework of general laws.
