There are three successive states of morality answering to the three principal stages of human life; the personal, the domestic, and the social stage. The succession represents the gradual training of the sympathetic principle; it is drawn out step by step by a series of affections which, as it diminishes in intensity, increases in dignity. This series forms our best resource in attempting as far as possible to reach the normal state; subordination of self-love to social feeling. These are the two extremes in the scale of human affections; but between them there is an intermediate degree, namely, domestic attachment, and it is on this that the solution of the great moral problem depends. The love of his family leads Man out of his original state of Self-love and enables him to attain finally a sufficient measure of Social love. Every attempt on the part of the moral educator to call this last into immediate action, regardless of the intermediate stage, is to be condemned as utterly chimerical and profoundly injurious. Such attempts are regarded in the present day with far too favourable an eye. Far from being a sign of social progress, they would, if successful, be an immense step backwards; since the feeling which inspires them is one of perverted admiration for antiquity. Since the importance of domestic life is so great as a transition from selfish to social feeling, a systematic view of its relations will be the best mode of explaining the spirit of Positive morality, which is in every respect based upon the order found in nature. The first germ of social feeling is seen in the affection of the child for its parents. Filial love is the starting-point of our moral education: from it springs the instinct of Continuity, and consequently of reverence for our ancestors. It is the first tie by which the new being feels himself bound to the whole past history of Man. Brotherly love comes next, implanting the instinct of Solidarity, that is to say of union with our contemporaries; and thus we have already a sort of outline of social existence. With maturity new phases of feeling are developed. Relationships are formed of an entirely voluntary nature; which have therefore a still more social character than the involuntary ties of earlier years. This second stage in moral education begins with conjugal affection, the most important of all, in which perfect fullness of devotion is secured by the reciprocity and indissolubility of the bond. It is the highest type of all sympathetic instincts, and has appropriated to itself in a special sense the name of Love. From this most perfect of unions proceeds the last in the series of domestic sympathies, parental love. It completes the training by which Nature prepares us for universal sympathy: for it teaches us to care for our successors; and thus it binds us to the Future, as filial love had bound us to the Past.
