It is to be noticed that part of the nature of a smaller group may be what it is for the sake of a larger group to which it belongs; and then we may speak of the function of the smaller group. Thus it appears probable that the family, in the form in which it now exists among us, is determined by the good of the nation; and we may say that the function of the family is to promote the advantage of the nation or larger society in some certain ways. But I do not think it would be right to follow Auguste Comte in speaking of the function of humanity; because humanity is obviously not a part of any larger organism for whose sake it is what it is. Now that we have cleared up the meanings of some of our words, we are still a great way from the definite solution of our question, 'What is the best conscience? or what ought I to think right?' For we do not yet know what is for the advantage of the community in the struggle for existence. If we choose to learn by the analogy of an individual organism, we may see that no permanent or final answer can be given, because the organism grows in consequence of the struggle, and develops new wants while it is satisfying the old ones. But at any given time it has quite enough to do to keep alive and to avoid dangers and diseases. So we may expect that the wants and even the necessities of the social organism will grow with its growth, and that it is impossible to predict what may tend in the distant future to its advantage in the struggle for existence. But still, in this vague and general statement of the functions of conscience, we shall find that we have already established a great deal.
