All this happened about 1840. The present year is 1887, and there seems no prospect of the sorcery weakening. The work to which these notes serve as an introduction may be taken as proof. Indeed, somebody has said that the men of Balzac have appeared as much in literature as in life, especially since the death of the novelist. Balzac seems to have observed the society of his day less than he contributed to form a new one. Such and such personages are truer to life in 1860 than in 1835. When one considers a phenomenon of such range and intensity, it does not suffice to employ words like infatuation, fashion, mania. The attraction of an author becomes a psychological fact of prime importance and subject to analysis. I think I can see two reasons for this particular strength of Balzac's genius. One dwells in the special character of his vision, the other in the philosophical trend which he succeeded in giving to all his writing. As to the scope of his vision, this /Repertory/ alone will suffice to show. Turn over the leaves at random and estimate the number of fictitious deeds going to make up these two thousand biographies, each individual, each distinct, and most of them complete--that is to say, taking the character at his birth and leaving him only at his death. Balzac not only knows the date of birth or of death, he knows as well the local coloring of the time and the country and profession to which the man belongs. He is thoroughly conversant with questions of taxation and income and the agricultural conditions. He is not ignorant of the fact that Grandet cannot make his fortune by the same methods employed by Gobseck, his rival in avarice; nor Ferdinand du Tillet, that jackal, with the same magnitude of operations worked out by that elephant of a Nucingen. He has outlined and measured the exact relation of each character to his environment in the same way he has outlined and measured the bonds uniting the various characters; so well that each individual is defined separately as to his personal and his social side, and in the same manner each family is defined. It is the skeleton of these individuals and of these families that is laid bare for your contemplation in these notes of Messieurs Cerfberr and Christophe. But this structure of facts, dependent one upon another by a logic equal to that of life itself, is the smallest effort of Balzac's genius. Does a birth-certificate, a marriage-contract or an inventory of wealth represent a person? Certainly not. There is still lacking, for a bone covering, the flesh, the blood, the muscles and the nerves. A glance from Balzac, and all these tabulated facts become imbued with life; to this circumstantial view of the conditions of existence with certain beings is added as full a view of the beings themselves.
