In certain fragments of this long work I have tried to popularize the amazing facts, I may say the marvels, of electricity, which in man is metamorphosed into an incalculable force; but in what way do the phenomena of brain and nerves, which prove the existence of an undiscovered world of psychology, modify the necessary and undoubted relations of the worlds to God? In what way can they shake the Catholic dogma? Though irrefutable facts should some day place thought in the class of fluids which are discerned only by their effects while their substance evades our senses, even when aided by so many mechanical means, the result will be the same as when Christopher Columbus detected that the earth is a sphere, and Galileo demonstrated its rotation. Our future will be unchanged. The wonders of animal magnetism, with which I have been familiar since 1820; the beautiful experiments of Gall, Lavater's successor; all the men who have studied mind as opticians have studied light--two not dissimilar things--point to a conclusion in favor of the mystics, the disciples of St. John, and of those great thinkers who have established the spiritual world--the sphere in which are revealed the relations of God and man. A sure grasp of the purport of this work will make it clear that I attach to common, daily facts, hidden or patent to the eye, to the acts of individual lives, and to their causes and principles, the importance which historians have hitherto ascribed to the events of public national life. The unknown struggle which goes on in a valley of the Indre between Mme. de Mortsauf and her passion is perhaps as great as the most famous of battles (_Le Lys dans la Vallee_). In one the glory of the victor is at stake; in the other it is heaven. The misfortunes of the two Birotteaus, the priest and the perfumer, to me are those of mankind. La Fosseuse (_Medecin de Campagne_) and Mme. Graslin (_Cure de Village_) are almost the sum-total of woman. We all suffer thus every day. I have had to do a hundred times what Richardson did but once. Lovelace has a thousand forms, for social corruption takes the hues of the medium in which it lives. Clarissa, on the contrary, the lovely image of impassioned virtue, is drawn in lines of distracting purity. To create a variety of Virgins it needs a Raphael. In this respect, perhaps literature must yield to painting.
