Was Christianity right in saying that the world was made for man? Was the account it adopted of the method and causes of Creation conceivably correct? Was the garden of Eden a historical reality, and were the Hebrew prophecies announcements of the advent of Jesus Christ? Did the deluge come because of man's wickedness, and will the last day coincide with the dramatic denouement of the Church's history? In other words, is the spiritual experience of man the explanation of the universe? Certainly not, if we are thinking of a scientific, not of a poetical explanation. As a matter of fact, man is a product of laws which must also destroy him, and which, as Spinoza would say, infinitely exceed him in their scope and power. His welfare is indifferent to the stars, but dependent on them. And yet that counter-Copernican revolution accomplished by Christianity--a revolution which Kant should hardly have attributed to himself--which put man in the centre of the universe and made the stars circle about him, must have some kind of justification. And indeed its justification (if we may be so brief on so great a subject) is that what is false in the science of facts may be true in the science of values. While the existence of things must be understood by referring them to their causes, which are mechanical, their functions can only be explained by what is interesting in their results, in other words, by their relation to human nature and to human happiness. The Christian drama was a magnificent poetic rendering of this side of the matter, a side which Socrates had envisaged by his admirable method, but which now flooded the consciousness of mankind with torrential emotions. Christianity was born under an eclipse, when the light of Nature was obscured; but the star that intercepted that light was itself luminous, and shed on succeeding ages a moonlike radiance, paler and sadder than the other, but no less divine, and meriting no less to be eternal. Man now studied his own destiny, as he had before studied the sky, and the woods, and the sunny depths of water; and as the earlier study produced in his soul--_anima naturaliter poeta_--the images of Zeus, Pan, and Nereus, so the later study produced the images of Jesus and of Mary, of Heaven and Hell, of miracles and sacraments. The observation was no less exact, the translation into poetic images no less wonderful here than there. To trace the endless transfiguration, with all its unconscious ingenuity and harmony, might be the theme of a fascinating science. Let not the reader fancy that in Christianity everything was settled by records and traditions. The idea of Christ himself had to be constructed by the imagination in response to moral demands, tradition giving only the barest external points of attachment. The facts were nothing until they became symbols; and nothing could turn them into symbols except an eager imagination on the watch for all that might embody its dreams.
