This introduction explains how and why the essays of Queer Bloomsbury combine the Bloomsbury Group’s personal lives with aspects routinely elevated to a higher status – art, politics, philosophy – understanding these as inseparable aspects of the same phenomenon. Contributors to this volume neither shrink from nor capitalise on sexual details, but are primarily interested in how group members’ queer perspectives enabled their thinking and its results. Sexual intimacy between friends of either gender was not only accepted, but understood as a rich source of intellectual, artistic, and philosophical affinity. Contemporary philosophical and political theory has returned to the insights cultivated by the Bloomsbury Group, if that return is characterised as a holistic way of living sexually, intellectually, artistically, ethically, and intimately, rather than in parts. Considering Bloomsbury as an interdisciplinary field – inhabited by artists, authors, philosophers, economists, political activists, art critics, journalists, and biographers – enriches our understanding of early twentieth-century cultures.
