Throughout Nature, the parental instinct is seen as a unique development, detached from and high above all other developments. Demanding, as it does, the complete surrender and self-denying labours of one individual in the interests of another, it differs from and traverses all other dictates. It impels a creature whose every instinct it had been--whose religion of biological survival it had been, indeed--to be wholly self-centred in its every aim and action, all at once to make another creature the focus of its interests and efforts. Where for a scratch, for a glance, the fierce female would have fallen tooth and nail upon another, now she surrenders meekly to the pangs of bringing offspring into life--and straightway licks and suckles the frail being that has riven her. Where she would furiously have driven off, or would have killed, another creature that approached her food, now she gives herself as food for this. Where lesser Fitness for survival on another's part had been signal for making such her prey, now Unfitness in the extremest degree claims her devotion and care. Superfluous to cite cases of maternal altruism. The mildest and most timid among creatures becomes fierce and courageous in defence of her young. Style it "merely instinct," if you will. It is none the less heroic on the part of every individual that obeys it, and does not obey it blindly and mechanically merely, but employs all her poor wit and resource to suit her heroism to the special circumstance. Without care and attention from the moment of its birth, the life of an infant would be reckoned in hours. The higher the organism, the more and for the longer period its infancy exacts unceasing devotion and nurture. Fish and moth and other species of low order are cast off in the egg. Chicks scramble out of the shell. The higher their grade in the scale of organisation and intelligence, the more helpless and incapable young creatures are to feed and to fend for themselves. Kittens are born blind and helpless, but after a few days they see and crawl about. The elephant-mother suckles and safeguards her baby-elephant for two whole years. Now, were there no purpose in all this--Were it not that such devotion to offspring serves as impulse and spur to the evolution and development of faculty in parents, Nature, in planning the complex human species, would, surely, have endowed the human infant and child with fuller powers of self-preservation. Were there other functions and aptitudes the exercise whereof would better stimulate and foster human progress, it is inconceivable that children would be, and would be for so long, the helpless, feckless, dependent mortals that they are.
