Is Georg Lukács one of the classical authors of the philosophical tradition? This question might appear somewhat odd in a collection of articles commemorating his centenary. It is just that, although the work of Lukács represents nothing less than a monument to all those who are interested in Marxism, as exemplified by a prodigious body of literature, it remains largely ignored in more traditional philosophy, which is often little disposed to consider even Marx himself as a genuine philosopher. Hermeneutics and analytic philosophy, two dominant currents at the present time, hardly ever concern themselves with the one who, since Merleau-Ponty, has been called the founding father of Western Marxism.²
