+The duty we owe to ourselves is the realization of our capacities and powers in harmony with each other, and in proportion to their worth as elements in a complete individual and social life.+--We have within us the capacity for an ever increasing fullness and richness and intensity of life. The materials out of which this life is to be developed are ready to our hands in those objects which we have been considering. One way of conduct toward these objects, which we have called duty; one attitude of mind and will toward them which we have called virtue, leads to those completions and fulfillments of ourselves which we have called rewards. Duty then to self; duty in its most comprehensive aspect, is the obligation which the existence of capacity within and material without imposes on us to bring the two together in harmonious relations, so as to realize the capacities and powers of ourselves and of others, and promote society's well being. In simpler terms our fundamental duty is to make the most of ourselves; and to become as large and genuine a part of the social world in which we live as it is possible for us to be. THE VIRTUE. +The habit of seeking to realize the highest capacities and widest relationships of our nature in every act is conscientiousness. Conscience is our consciousness of the ideal in conduct and character. Conscience is the knowledge of our duty, coupled as that knowledge always is with the feeling that we ought to do it.+--Knowledge of any kind calls up some feeling appropriate to the fact known. Knowledge that a given act would realize my ideal calls up the feeling of dissatisfaction with myself until that act is performed; because that is the feeling appropriate to the recognition of an unrealized yet attainable ideal. Conscience is not a mysterious faculty of our nature. It is simply thought and feeling, recognizing and responding to the fact of duty, and reaching out toward virtue and excellence. The objective worth of the deliverances and dictates of the conscience of the individual, depends on the degree of moral enlightenment and sensitiveness he has attained. The conscience of an educated Christian has a worth and authority which the conscience of the benighted savage has not. Since conscience is the recognition of the ideal of conduct and character, every new appreciation of duty and virtue gives to conscience added strength and clearness.
