Philosophy Bites: Cynthia Freeland on Portraits. This is a really great episode. Art history, portraiture, photography, self-representation, etc. One of the topics that came up was Roland Barthes’ book Camera Lucida, a short volume on photography written after his mother’s death. (See also his journal excerpts from the same time period.) Given the choice, Freeland would like David Hockney to do her own portrait.
