Starting from an analysis of Griefs. Poégrammes (1975) and several other collections of poetry, Michel Biron shows how poetic fervour, in the work of Gilbert Langevin, becomes an incontrovertible force embodying the meaning of the word "revolt" in the aftermath of the Révolution tranquille. Langevin exalts poetry as the ultimate value providing shelter in a world made over to the cold cynicism of bureaucrats. With an uncertain talent, capable at times of a melancholy and lucid detachment, Langevin clings to poetry as to a basic, indisputable truth. Analysis suggests that this exaltation of the poem finds its social legitimacy outside poetry, in the cultural discourse of the 1970s.
