Yet his inner life was full of difficulty and unhappiness. There were in him two strains, two warring impulses, to which we must attribute many of the griefs and disappointments of his life: for his great accomplishment both as poet and as founder of the _Cahiers de la Quinzaine_ brought him little personal joy. On one side of his nature he was proud, vehement, combative; full of a destructive energy, an obstinate fanaticism, which found vent in his violent political pamphlets, often expressing with the uncouth vigour of the peasant his uncompromising hates and loves. Though so ardent a Christian, he was neither meek nor gentle. He could never resist giving blow for blow, and by his impatience and intolerance alienated by turns his socialist and Catholic friends. About 1910, having thus quarrelled with most of his associates, he withdrew into a voluntary retirement, in which the spiritual side of his divided temperament seems at last to have had some opportunity of growth. His mystical poems—all composed between 1910 and 1913—show to us the love and exaltation of which he now became capable; the purity of that vision which had inspired his vigorous guerilla warfare against the shams and sordidness of modern life, and which now became the chief factor in his consciousness. Writing in 1912 to his old friend Joseph Lotte, he says, “Mon vieux, j’ai beaucoup changé depuis deux ans; je suis devenu un homme nouveau. J’ai tant souffert et tant prié. Tu ne peux pas savoir.” The secret of this inner conflict, of the terrible months during which, as he afterwards confessed, he was unable to say “Thy will be done,” he revealed to none; but hints of the way by which he had passed may be found in his poems. The mystical certitude which inspires their most beautiful passages seems never to have obtained complete control of his psychic being. The life of prayer and the life of personal struggle persisted side by side, not fully harmonized; and it is doubtful whether he ever achieved that complete surrender to the divine action “in which alone we do not surrender our true selves,” which is characteristic of the developed mystic life. “Celui qui s’abandonne ne s’abandonne pas, et il est le seul qui ne s’abandonne pas.” It was surely to himself that Péguy addressed this observation, and it represents his own central need. Those profound readjustments of character, that unselfing of the moral nature, which must precede spiritual unification, and so are the only foundations of inner peace, had never been accomplished in him. Like his patroness and heroine St. Joan, he combined the temperaments of fighter and dreamer, but he never succeeded in fusing them in one.
