Two types of conception of a Way of Life are important for a consideration of the question of the forming and testing of ideals of conduct, and consequently for a consideration of our questions regarding the relation of ideals to practice. The one type is more, the other type less general. The one has reference to man as man, the other to particular classes of man, with relation to their specific function in society. The former issues in the idea of a universal ethic, the latter in the idea of a professional code. Thus the former has a wider generality, the latter has a greater concreteness. Ethical progress seems to me to require that both types should be kept in view, and used to guide man's efforts.
