 Subsequent to Otherwise than Being,Levinas’ works return to and refine his major themes. These works include Transcendence and Intelligibility (1984), In the Time of the Nations (1988), Entre Nous (1991), and Alterity and Transcendence (1995), all of which are collections of essays from various periods between 1951 and 1989. However, the first of these collections to appear, entitled Of God Who Comes to Mind (1982), contains the important essay “God and Philosophy” (1975; OGCM: 55–78), which is a critical confrontation with the God of Descartes and Malebranche, and a subtle debate with Heidegger. This essay is followed by the transcript of a two-hour discussion with professors from the University of Leyden (OGCM: 79–99), in which social problems infrequently addressed by Levinas are  raised.[48]  Despite the wide temporal gamut run by these publications, we find few new developments, other than a clearer resolve to address the ambiguity intrinsic to the signifier “God” (OGCM: §§10–13, 17–19), and the verbal dynamics of being (corresponding to Heidegger’s Wesen), henceforth characterized by Levinas’ neologism “essance” (OGCM: 43–51).
