For some, Péguy is "an anarchist who put holy water in his oil"; for others, a dangerous rebel whose "head is revolution". A socialist and a Catholic, a pious poet and a raging polemicist, Péguy was a man whose path was sometimes chaotic, but always bouncy. Few authors have had as controversial a posterity as he. One hundred years after his death, it's time to do justice to this unclassifiable thinker, who was little-known in his day, but who has so much to say to our own.Yves Rouvière's drawings give substance to the words, "incarnating the spiritual", according to one of Péguy's cherished intuitions.
