The universal appeal of Charles Peguy (1873-1914) has made him one of France's best-loved poets. His influence has also caused a gentle but unmistakable shift in twentieth-century Catholic thought, leaving a legacy that continues in such writers as Bernanos, Marcel, Guardini, de Lubac, and Balthasar. In The Portal of the Mystery of Hope Peguy offers a comprehensive theology ordered around the often-neglected second theological virtue, which is incarnated in his celebrated image of the "little girl Hope". As the first critical edition of Peguy's poetry to appear in English, this volume also contains a biographical chronology, a bibliography, and a host of notes that situate the poem in the context of Peguy's life.
