Effet bienfaisant d'une phrase ~ Beneficent effect of a phrase

From Roland Barthes by Roland Barthes:

X tells me that one day he decided "to exonerate his life from his unhappy loves," and that this phrase seemed so splendid to him that it almost managed to compensate for the failures which had provoked it; he then determined (and determined me) to take more advantage of this reservoir of irony in all (aesthetic) language.
