 Although Marcuse breaks with Heidegger in 1932, for some scholars the break is not all that clear. Martin Jay claims that when Marcuse joined the Institute, the influence of Horkheimer was so great that Marcuse “abandoned Heidegger’s vocabulary, as the impact of phenomenology on his thinking began to recede” (Jay 1973: 76). However, in a letter to Horkheimer on May 13, 1935, Adorno strongly suggests that Marcuse was still a Heideggerian (Marcuse/Kellner 1998: 16 n.22). One must, however, maintain some level of suspicion of Adorno’s claim since he and Marcuse were engaged in competition for Horkheimer’s favor. Nevertheless, the question of Marcuse’s Heideggerianism is still of interests for Marcuse scholars. For example, Richard Wolin writes: “In Marcuse’s postwar writings, the Heideggerian dimension is muted but nevertheless traceable” (Wolin 2001: 167).
