This essay traces the development of the philosophical debates concerning active powers and human agency in eighteenth-century Scotland. I examine how and why Scottish philosophers such as Francis Hutcheson, George Turnbull, David Hume, and Henry Home, Lord Kames, depart from John Locke’s and other traditional conceptions of the will and how Thomas Reid and Dugald Stewart reinstate Locke’s distinction between volition and desire. Moreover, I examine what role desires, passions, and motives play in the writings of these and other Scottish (...) Enlightenment philosophers on human agency and draw attention to their underlying disputes concerning liberty and necessity. I end by reflecting on how classifications of principles of actions changed in eighteenth and early nineteenth-century Scottish philosophy. (shrink)

In the conclusion to the first book of the Treatise, Hume's skeptical reflections have plunged him into melancholy. He then proceeds through a complex series of stages, resulting in renewed interest in philosophy. Interpreters have struggled to explain the connection between the stages. I argue that Hume's repeated invocation of the four humors of ancient and medieval medicine explains the succession, and sheds a new light on the significance of skepticism. The humoral context not only reveals that Hume conceives of (...) skepticism primarily as a temperament, not a philosophical view or system. It also resolves a puzzle about how Hume can view skepticism as both an illness and a cure. The skeptical temperament can, depending on its degree of predominance, either contribute to or upset the balance of temperaments required for proper mental functioning. (shrink)

I begin with a diagnosis. Present-day scholarly work on the Scottish Enlightenment is bifurcated: it is either focused on the areas of moral philosophy or of natural philosophy, broadly construed in both cases. The aspiration to combine these inquiries is rare and unsystematic. This paper makes a case for the need and possibility of a perspective that conceives moral and natural inquiry as integrated enterprises in the period. It also suggests that potentially useful interpretive devices can be adopted from the (...) historiography of science and philosophy, as well as science studies. (shrink)

For Jerry Fodor, Hume’sTreatise of Human Natureis “the foundational document of cognitive science” whose significance transcends mere historical interest: it is a source of theoretical inspiration in cognitive psychology. Here I am going to argue that those reading Hume along Fodor’s lines rely on a problematic, albeit inspiring, construction of Hume’s science of mind. My strategy in this paper is to contrast Fodor’s understanding of the Humean mind (consonant with the widely received view of Hume in both cognitive science and (...) much of Hume scholarship) with an alternative understanding that I propose. I thereby intend to show that the received view of Hume’s science of mind can be fruitfully revised while critically engaging with Fodor’s contemporary appropriation. Consequently, I use this occasion to put forward a rather unorthodox interpretation of Hume’s theory in dialogue with Fodor as my guide. (shrink)

This paper sketches a recently emerging divide between two interpretations of Hume's methodology and philosophy of science. On the first interpretation Hume relies on an inductive methodology and provides a (Newtonian) dynamic theory of the mind, and his philosophy of science reflects this methodology. On the second, Hume relies on inferences to the best explanation via comparative analysis of instances, and offers an anatomy of the mind relying on a chemical and organic imagery. The paper also aspires to lean the (...) reader's sympathies toward the latter interpretation while outlining some of its potential consequences for the character of Hume's psychology, the limits of associationism, and his empiricism.

In this paper I show how what came to be known as “the double law of habit,” first formulated by Joseph Butler in a discussion of moral psychology in 1736, was taken up and developed by medical physiologists William Porterfield, Robert Whytt, and William Cullen as they disputed fundamental questions regarding the influence of the mind on the body, the possibility of unconscious mental processes, and the nature and extent of voluntary action. The paper shows, on a particular topic, the (...) overlap between eighteenth-century philosophical writings on the science of human nature on the one hand,and medical writings and lectures in physiology on the other. Other early modern writers discussed in the paper include René Descartes, Herman Boerhaave and David Hume. (shrink)
