This volume presents a collection of newly commissioned essays on the work of L. Susan Stebbing (1885-1943). Stebbing was an important figure in the development of analytic philosophy in the first half of the twentieth century, and a pioneer of the social utility of philosophy and of the application of logical analysis to critical inquiry into language use. The separate studies of Stebbing’s work included in this volume offer fresh perspectives across three broad topics: Logic and Cambridge Analysis; Idealism, Realism and the Philosophy of Science; and Public Philosophy and Social Engagement The volume brings together seven chapters by leading international scholars in the field, along with a contextualising introduction, in order to advance understanding of the importance, originality and continuing significance of Stebbing’s remarkable oeuvre.
