Allow me, Gentlemen, to pose this question in a more serious manner. Do I need to tell you that it is not a question at first of the natural, physiological, ethnographic difference that exists between individuals, but of the social difference, that is produced by the economic organization of society? Give to all the children, from their birth, the same means of maintenance, education, and instruction; give then to all the men thus raised the same social milieu, the same means of earning their living by their own labor, and you will see then that many of these differences, that we believe to be natural differences, will disappear because they are nothing but the effect of an unequal division of the conditions of intellectual and physical development - of the conditions of life.
