Always, in the beginning, before his conscious life dawned, he had crawled toward the mouth of the cave. And in this his brothers and sisters were one with him. Never, in that period, did any of them crawl toward the dark corners of the back-wall. The light drew them as if they were plants; the chemistry of the life that composed them demanded the light as a necessity of being; and their little puppet-bodies crawled blindly and chemically, like the tendrils of a vine. Later on, when each developed individuality and became personally conscious of impulsions and desires, the attraction of the light increased. They were always crawling and sprawling toward it, and being driven back from it by their mother. It was in this way that the grey cub learned other attributes of his mother than the soft, soothing, tongue. In his insistent crawling toward the light, he discovered in her a nose that with a sharp nudge administered rebuke, and later, a paw, that crushed him down and rolled him over and over with swift, calculating stroke. Thus he learned hurt; and on top of it he learned to avoid hurt, first, by not incurring the risk of it; and second, when he had incurred the risk, by dodging and by retreating. These were conscious actions, and were the results of his first generalisations upon the world. Before that he had recoiled automatically from hurt, as he had crawled automatically toward the light. After that he recoiled from hurt because he _knew_ that it was hurt. He was a fierce little cub. So were his brothers and sisters. It was to be expected. He was a carnivorous animal. He came of a breed of meat-killers and meat-eaters. His father and mother lived wholly upon meat. The milk he had sucked with his first flickering life, was milk transformed directly from meat, and now, at a month old, when his eyes had been open for but a week, he was beginning himself to eat meat—meat half-digested by the she-wolf and disgorged for the five growing cubs that already made too great demand upon her breast. But he was, further, the fiercest of the litter. He could make a louder rasping growl than any of them. His tiny rages were much more terrible than theirs. It was he that first learned the trick of rolling a fellow-cub over with a cunning paw-stroke. And it was he that first gripped another cub by the ear and pulled and tugged and growled through jaws tight-clenched. And certainly it was he that caused the mother the most trouble in keeping her litter from the mouth of the cave.
