One of the main features of the modern, organic society is the importance, sacredness even, given to the concept—social fact—of the individual. The individual, rather than the collective, becomes the focus of rights and responsibilities, the center of public and private rituals holding the society together—a function once performed by the religion. To stress the importance of this concept, Durkheim talked of the "cult of the individual":Thus very far from there being the antagonism between the individual and society which is often claimed, moral individualism, the cult of the individual, is in fact the product of society itself. It is society that instituted it and made of man the god whose servant it is.Durkheim saw the population density and growth as key factors in the evolution of the societies and advent of modernity. As the number of people in a given area increase, so does the number of interactions, and the society becomes more complex. Growing competition between the more numerous people also leads to further division of labour. In time, the importance of the state, the law and the individual increases, while that of the religion and moral solidarity decreases.
