In lieu of an abstract, here is a brief excerpt of the content:Hume on Tranquillizing the Passions John Immerwahr Borrowingafragmentfrom thelyric poetArchilochus, Sir IsaiahBerlin once divided thinkers into two categories: foxes, who know many things; and hedgehogs, who know only one, "one big thing."1 Although Berlin does not include Hume in either list, it is tempting to put him with the foxes. Indeed, Hume's corpus is brilliantly eclectic, ranging with equal facility over an impressive array of seemingly diverse subjects such (...) as epistemology, ethics, political science, religion, psychology, history, criticism, economics, and demography. Many of Hume's admirers have not even attempted to find a unity here, and Hume's less generous critics have attributed this diversity to an incessant hunger for "literary fame" which supposedly led Hume from topic to topic, always searching for popular acclaim and recognition.2 The dazzling diversity of Hume's thinking has obscured some important underlying themes; Hume is more of a hedgehog than he initially appears. At the centre of many of Hume's discussions is a recurring conviction about the nature of human well-being and the means to obtain it. This insistence—which can be found in each stage ofHume's career and in writings on virtually every topic—provides one way of finding an overarching unity to his thought and invites us to rethink some ofthe conventional wisdom about Hume. In this essay I argue that many of Hume's investigations are informed by his early distinction between calm and violent passions. Wherever we turn we find Hume insisting that people arehappiest and governments are most stable when emotional calmness prevails. Hume alsohas astrategy, which Icall "moderation through opposition," which is designedto"tranquillize and soften"the passions.3 This strategy also becomes a stylistic principle which informs Hume's own writing, especially his popular works. This essay begins with a brief discussion of the calm/violent distinction itself. I then sketch out the role ofcalm passions in Hume's treatment of rationality, happiness, morality, politics and religion. Next I turn from Hume's diagnosis to his proposed cure, and discuss the strategy that Hume presents for enhancing the calm passions; indeed, Hume's writing style itselfis often designed to implement this strategy. I then discuss the context of Hume's insight, arguing that while it grows out of a cosmopolitan continental paradigm of using Volume XVIII Number 2 293 JOHN IMMERWAHR passions to oppose passions, Hume's own use ofit is tailored to rather specific features of the political and intellectual life of eighteenth centuryEdinburgh. The essay concludesby discussingthe implications of these findings for reading ofHume's works. Passions: Calm and Violent One characteristic feature of the thinkers of the "Scottish Enlightenment" was a desire tofound moral concepts in a scientific and empirical understanding ofhuman nature, rather than upon abstract conceptions of virtue and justice.4 These thinkers were particularly interestedin non-cognitivistelements ofhuman nature, such as"taste," "sentiment" and the "passions,"5 and they were also interested in discriminatingamongthe feelings and passions to discover those which were most beneficial to the individual or society. One Scottish philosopher who was particularly influential upon Hume in this connection was Francis Hutcheson. In discussing the passions, Hutcheson distinguished between what he called the "calm desire of good" and the "particular passions towards objects immediately presented to the senses." Hutcheson noted that these calm desires were frequently powerful enough to conquer particular passions such as "lust or revenge."6 The calm passions are thus very important to our understanding ofhuman motivation. As in so many other things, Hume also appears to be influenced by Hutcheson on the existence and importance of "calm passions." Early in Treatise 2, Hume expands on Hutcheson's idea that our experience ofan emotion or passion can be described as either "calm" or "violent"7 (also "soft" or "tender," "rough" or "fierce").8 The main difference between calmness and violence has to do with the intensity with which a passion is experienced. When we experience violent passions we feel an "uneasiness" (T 418) and sometimes "disorders and agitations" (E 17).9 Other passions are "calm" in that they cause "no disorder in the soul" and "little emotion in the mind" (T 417).10 Hume's main point is that...
