 Seventeenth-century accounts are rife with long inventories of emotions, although the list-making urge seems to have dampened a bit by the eighteenth century, with many fewer authors pretending to exhaustive catalogues. Compared to his contemporaries, Descartes looks temperate with a docket of a mere six simple passions, although he also constructed a host of complex ones out of these six. Hobbes offered a list of about thirty in the Leviathan (1651), and more than twenty-five in The Elements of Law (ms. 1640). The head count for Spinoza is a bit trickier to determine, but the third book of his Ethics (ms. 1675) defines at least forty affects. Locke’s short discussion in Book II, chap. XX of the Essay Concerning Human Understanding (1690) treats eleven; whereas Hume’s Treatise and “Dissertation on the Passions” (1757) described about ten broad passions, as well as numerous sub-species and adjuncts, even before turning to the moral or aesthetic sentiments. This tendency is not simply found among the great early modern systems-builders. In the seventeenth century in particular, just about everybody (and their maiden aunt and bachelor uncle) seems to have joined in the hunt for new and distinctive lists of emotions. For instance, large portions of Thomas Wright’s The Passions of the Mind In General (1604) and Nicholas Coeffeteau’s Tableau des passions humaines, de leurs causes et leurs effets (ms. 1621) are devoted to such lists. A short play of 1630, Pathomachia; or the Battel of Affections, even makes proper taxonomy the motor of what little drama it possesses.
