Author and philosopher Elizabeth V. Spelman will talk about her "deep dive" into trash to discover who we are and what we value. Scavenging with abandon from sundry sources, including Darwin, Freud, Plato, Buddha, Milton, and Locke, the author explores the extent to which people rely on trash and waste to make sense of their lives and to shape connections with others. Elizabeth V. Spelman is Professor of Philosophy and Barbara Richmond 1940 Professor in the Humanities, Smith College.
