The Tanner Lectures on Human Values, founded July 1, 1978, at Clare Hall, Cambridge University, was established by the American scholar, industrialist, and philanthropist Obert Clark Tanner. Lectureships are awarded to outstanding scholars or leaders in broadly defined fields of human values, and transcend ethnic, national, religious, or ideological distinctions. Volume 25 features lectures given by Frans B.M. de Waal, Richard Dawkins, Christine M. Korsgaard, Seyla Benhabib, and Harry Frankfurt.

Grethe B. Peterson is director of the Tanner Lectures on Human Values. She lives in Park City, Utah.
