This volume of the Townsend Papers in the Humanities commemorates the twenty-fifth year of the Doreen B. Townsend Center for the Humanities at the University of California, Berkeley. As such, the volume is an attempt to capture the breadth and depth of lectures and events presented by the center. Many are revised versions of lectures and presentations organized in connection with the annual appointment of the Avenali Professor in the Humanities at Berkeley (generously funded by Joan and Peter Avenali), or Berkeley's Una's Lecturer (endowed in the memory of Una Smith Ross, Class of 1911); several are based on other events presented by the center over the years, such as the "Humanities Perspectives on Aging" program or the "Futures" lecture series organized to commemorate the center's tenth anniversary. All are the reflection of a public event before a live audience. We have chosen to retain references to the live event where they occur, though space limitations would not permit the inclusion of audience questions.
