Juridical pragmatism and sociological trend in the American law

The article covers the legal theories which appeared in the USA in the first quarter of the XX century and were caused by the social and economic changes: juridical pragmatism and sociological trend. Having appeared originally as the society protest against the existing order and the inability of the legal system to overcome social problems, these concepts later became the basis of the court rule-making and had a substantial influence on the American judges' and American lawyers' way of thinking.
