If _Nunc dimittis_ is a psalm for love to sing, it is even more appropriate for parental piety. On seeing heirs and representatives of ours already in the world, we are inclined to give them place and trust them to realise our foiled ambitions. They, we fancy, will be more fortunate than we; we shall have screened them from whatever has most maimed our own lives. Their purer souls, as we imagine, will reach better things than are now possible to ours, distracted and abused so long. We commit the blotted manuscript of our lives more willingly to the flames, when we find the immortal text already half engrossed in a fairer copy. In all this there is undoubtedly a measure of illusion, since little clear improvement is ordinarily possible in the world, and while our children may improve upon us in some respects, the devil will catch them unprepared in another quarter. Yet the hope in question is a transcript of primary impersonal functions to which nature, at certain levels, limits the animal will. To keep life going was, in the beginning, the sole triumph of life. Even when nothing but reproduction was aimed at or attained, existence was made possible and ideally stable by securing so much; and when the ideal was enlarged so as to include training and rearing the new generation, life was even better intrenched and protected. Though further material progress may not be made easier by this development, since more dangers become fatal as beings grow complex and mutually dependent, a great step in moral progress has at any rate been taken. In itself, a desire to see a child grow and prosper is just as irrational as any other absolute desire; but since the child also desires his own happiness, the child’s will sanctions and supports the father’s. Thus two irrationalities, when they conspire, make one rational life. The father’s instinct and sense of duty are now vindicated experimentally in the child’s progress, while the son, besides the joy of living, has the pious function of satisfying his parent’s hopes. Even if life could achieve nothing more than this, it would have reached something profoundly natural and perfectly ideal. In patriarchal ages men feel it is enough to have inherited their human patrimony, to have enjoyed it, and to hand it down unimpaired. He who is not childless goes down to his grave in peace. Reason may afterward come to larger vistas and more spiritual aims, but the principle of love and responsibility will not be altered. It will demand that wills be made harmonious and satisfactions compatible. [Sidenote: Adventitious functions assumed by the family.]
