The poetry of the soul--faith, liberty, virtue, devotion--made their appearance in the world with the two great races which, in one sense, have made humanity, viz., the Indo-European and the Semitic races. The first religious intuitions of the Indo-European race were essentially naturalistic. But it was a profound and moral naturalism, a loving embrace of Nature by man, a delicious poetry, full of the sentiment of the Infinite--the principle, in fine, of all that which the Germanic and Celtic genius, of that which a Shakespeare and a Goethe should express in later times. It was neither theology nor moral philosophy--it was a state of melancholy, it was tenderness, it was imagination; it was, more than all, earnestness, the essential condition of morals and religion. The faith of humanity, however, could not come from thence, because these ancient forms of worships had great difficulty in detaching themselves from Polytheism, and could not attain to a very clear symbol. Brahminism has only survived to the present day by virtue of the astonishing faculty of conservation which India seems to possess. Buddhism failed in all its approaches toward the West. Druidism remained a form exclusively national, and without universal capacity. The Greek attempts at reform, Orpheism, the Mysteries, did not suffice to give a solid aliment to the soul. Persia alone succeeded in making a dogmatic religion, almost Monotheistic, and skilfully organized; but it is very possible that this organization itself was but an imitation, or borrowed. At all events, Persia has not converted the world; she herself, on the contrary, was converted when she saw the flag of the Divine unity as proclaimed by Mohammedanism appear on her frontiers.
