This volume transcribes Foucault's faculty seminar at the University of Vermont in the autumn of 1982. ``Technologies'' implies ``techniques,'' so the title means how one deals with oneself. Tracing the historical dialectic of ``take care of yourself'' and ``know yourself'' from Socrates to John Cassian (360-435), Foucault cites Socrates/Alcibiades and Marcus Aurelius/Fronto as examples of instruction in self-technology. The seminar format renders Foucault's exposition extremely accessible, making thisone of his last worksa good point of departure for all his works. But given the spectacular spread of AIDS, we cannot read his subtle advice for self-examination as we would have in 1982. Marilyn Gaddis Rose, SUNY at Binghamton.
