life, had yearned toward this light and urged his body toward it in the same way that the cunning chemistry of a plant urges it toward the sun.
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 gray 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 or 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.
