This article aims to analyze some central motifs of the thought of Denis de Rougemont, within the intellectual context in which it takes shape. Therefore, we will highlight the essential connections to the French personalism (with important references to the figure of Emmanuel Mounier) as it develops from the thirties, in its complex ancestry within the European culture of the century. More generally, we will explore the concept of “person” as well as Denis de Rougemont intends it, the role that human otherness plays in the context of interpersonal relationships, the dimensions of voir and regarder (as they are themed between mysticism and pragmatism within the Journal d'un Intellectuel en chômage) and the dichotomy amour-passion/amour action intended as leitmotif of the fundamental work of the author, L'Amour et L'Occident
