The movement in modern times to free women form the discrimination to which they have been subject in civil society and in political legislation. As such, it has two discernible roots, one sociological and the ohter ideological. On the sociological level is the recognized fact that women in all parts of the world are coming more and more into their won, to find their places alongside of men, making their distinctive contribution in the professions, in education, and in the the sciences. The other root is not so much factual as ideological, and stands at variance with Christian principles. It argues from a massive discrimination of women by men, and urges women to revolt against men. The best known propoment of theis ideology was Nikolai Lenin (1874-1924), who urfged that "the success of a revoltution depends upon the degree of participation by women." On these terms, women's liberation is simply part of the larger struggles for the eventual creation of a classless society.
