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. "Creed and Deed: A Series of Discourses," originally published in 1880, contains popular lectures that were requested by the New York Society for Ethical Culture, which Adler established. This reprint is taken from the original publication, which abridged and condensed Adler's lectures on immortality and religion. The other lectures are in their original form without any serious modification. "The First Anniversary Discourse" reviews the work of the year, and gives a brief account of the motives which prompted the Society to organize and the general animus by which its labors were directed. The lecture entitled "The Form of the Ideal" foreshadows the constructive purpose of the movement.
