Solid scholarship, if dense. Though some of the contributors seem to have been personally acquainted with and fond of Marcuse, the discussion is admirably sober and there is no shortage of criticism. Recommended for readers seeking an angle on a particular aspect of Marcuse's thought. For me this was aesthetics, and Bronner's essay (Ch. 7) is an exemplary contribution.
With the possible exception of Section V, "The Political Dimension," the rest of the collection is very dense and specialized and I cannot claim to have understood it well. The work on Marcuse's relationships to Hegel and Heidegger is especially difficult for a non-specialist and probably not terribly relevant either. Ditto the final essay on technology and Marxism. But if you're a glutton for punishment like I am, you'll at least come away with some new additions to your reading list and a better sense of the academic aftershocks of Marcuse's work.
