As far as the increase of the average duration of life is concerned, I recognize the fact, but at the same time I declare the observation incorrect. Let us explain that. Suppose a population of ten million souls: if, from whatever cause you will, the average life should increase five years for a million individuals, mortality continuing its ravages at the same rate as before among the nine other millions, it would be found, on distributing this increase among the whole, that on an average six months had been added to the life of each individual. It is with the average length of life, the so-called indicator of average comfort, as with average learning: the level of knowledge does not cease to rise, which by no means alters the fact that there are today in France quite as many barbarians as in the days of Francois I. The charlatans who had railroad speculation in view made a great noise about the importance of the locomotive in the circulation of ideas; and the economists, always on the lookout for civilized stupidities, have not failed to echo this nonsense. As if ideas, in order to spread, needed locomotives! What, then, prevents ideas from circulating from the Institute to the Faubourgs Saint-Antoine and Saint-Marceau, in the narrow and wretched streets of Old Paris and the Temple Quarter, everywhere, in short, where dwells this multitude even more destitute of ideas than of bread? How happens it that between a Parisian and a Parisian, in spite of the omnibus and the letter-carrier, the distance is three times greater today than in the fourteenth century? The ruinous influence of machinery on social economy and the condition of the laborers is exercised in a thousand ways, all of which are bound together and reciprocally labelled: cessation of labor, reduction of wages, over-production, obstruction of the market, alteration and adulteration of products, failures, displacement of laborers, degeneration of the race, and, finally, diseases and death. M. Theodore Fix has remarked himself that in the last fifty years the average stature of man, in France, has diminished by a considerable fraction of an inch. This observation is worth his previous one: upon whom does this diminution take effect? In a report read to the Academy of Moral Sciences on the results of the law of March 22, 1841, M. Leon Faucher expressed himself thus: Young workmen are pale, weak, short in stature, and slow to think as well as to move. At fourteen or fifteen years they seem no more developed than children of nine or ten years in the normal state. As for their intellectual and moral development, there are some to be found who, at the age of thirteen, have no notion of God, who have never heard of their duties, and whose first school of morality was a prison.
