We are publishing here for the first time a talk that Herbert Marcuse delivered at Stanford University on April 1, 1966, as part of a two-day conference on Paul A. Baran, entitled “Baran and American Radicalism Today”—commemorating the second anniversary of Baran’s death (on March 26, 1964). The talk was transcribed from a recording from the conference made available to us by Baran’s son, Nicholas Baran. Various editorial annotations have been added in the form of endnotes.
