Charles Pierre Péguy was a noted French poet, essayist, and editor. His two main philosophies were socialism and nationalism, but by 1908 at the latest, after years of uneasy agnosticism, he had become a believing but non-practicing Roman Catholic.
From that time, Catholicism strongly influenced his works.
