The problem of moral principles in the life of an individual and society has become rather acute in the context of the global spread of consumerism as the installation of modern civilized behavior of the individual. Traditionally, moral foundations are investigated as moral principles of individual behavior. The article draws attention to the problem of moral foundations of social life, which was first identified by the Russian philosopher V. Solovyov. The author considers two issues. The first one is the problem of moral foundations: whether morality has a religious origin or its roots are hidden in sociogenesis, in establishing principles of behavior in cultural communities. The second problem concerns the existence of issues of morality in public life and its impact on social relations. The article shows that the moral principles express solidarity relations among people. They arise in the course of new programs formation of symbolic behavior in communities following the way of active sociogenesis. New behavior, which is programmed by culture, requires establishing solidarity relations among members of the society, because deprived of such relationships, socio genetic development becomes impossible. Cooperation, based on the feeling of inner unity, is essential to the society. For this reason, moral foundations turn out to be the system principles of social organization, including economic life and economic relations in the society. Moral progress in the history of society is manifested in the development of solidarity principles up to the level of universal human morality, which defines the principles of behavior for societies and individuals.
