Friedman calls Inhering, father of modern sociological jurisprudence. As Duguit was building on the work of Comte and Durkheim, Ihering was found building on the work of Bentham and Mill. Inhering was a social utilitarian, he did not deny the concept of sovereign state as that of duguit but set a very practical relation between analytical school and utilitarian principles.
Inhering defines law as the sum of the conditions of social life in the widest sense of the term as secured by the power of the state through eternal compulsion.
