Abstract: According to Corbin, the nineteenth century invents a “properly romantic emotional grammar” imposed by 1793 and, prior to that, by sensualist philosophy and the Enlightenment. This modernity does not escape Vigny. A sociopolitical dynamic, emotion constitutes, according to him, a crucial challenge for the modern representations of power. It is an analytical category that makes it possible to think psychosociologically about the individual in history, taking note of the “passionate milieu” of any collective organization.
