Abstract
If love is the founding novel of the West, it expresses its political haunts far more than the assurance of its moral edification. This is the case not onlyin Albert Cohen'sBelle du seigneur , but also, thirty years earlier, in Denis de Rougemont's L'Amour en Occident . From here, we undertake an analysis of the fole amor as it unfolds in the different versions of Tristan and Isolde in the 12th and 13th centuries, examining the shifts they make in the trajectories of desire between love, death and war. The result is a questioning of the historicity of the categories of courtly love, but also of the ennobling function of a feeling that is both intense and distanced.
