Susan James, professor of philosophy at Birkbeck College in London, has focused on the passions and their ethical and political implications in the history of early modern philosophy in the seventeenth and eighteenth century, as well as political and social philosophy, and feminist philosophy. She has recently explored these themes in a series of articles about Spinoza, and also in a book, to be published in March, 2012, Spinoza on Philosophy, Religion and Politics: The Theologico-Political Treatise.
