Considered by many to be one of the major influences on modern Humanistic Judaism, Felix Adler (1851-1933) was a professor of political and social ethics and a social reformer who founded the Ethical Culture movement. Adler was also a popular, dynamic speaker and lecturer. "The Religion of Duty" documents some of the best thoughts he presented over the years. Topics include the first step towards a religion, changes in the conception of God, teaching of Jesus in the modern world, standards of conduct based on the religion of duty, the ethical attitude toward pleasure and suffering, and the essential difference between ethical societies and the churches.
