“Yiddish has not yet said its last word. It contains treasures that have not been revealed to the eyes of the world. It was the tongue of martyrs and saints, of dreamers and Cabalists — rich in humor and in memories that mankind may never forget. In a figurative way, Yiddish is the wise and humble language of us all, the idiom of frightened and hopeful Humanity.”

Mont Saint Michel and Chartres (1904)
Context: The schoolmen saw their duty in one direction; Francis saw his in another; and [... ] the two paths seem to be the only roads that can exist, if man starts by taking for granted that there is an object to be reached at the end of his journey. The Church embracing all mankind, had no choice but to march with caution, seeking God by every possible means of intellect and study. Francis, acting only for himself, could throw caution aside and trust implicitly in God [.... ] He carried to its last point the mystical Union wth God, and its necessary consequence of contempt and hatred of human intellectual processes. Even Saint Bernard would have thought his ideas wanting in that mesure which the French mind so much prizes. At the same time we had best try, as innocently as may be, to realise that no final judgement has yet been pronounced, either by the Church or by Society or by Science, on either or any of these points; and until mankind finally settles to a certainty where it means to go, or whether it means to go anywhere,— what its object is, or whether it has an object,— Saint Francis may still prove to have been its ultimate expression. In that case, his famous Chant,— the Cantico del Sole,— will be the last word of religion, as it was probably its first.
