"Another point which we have here to consider is the part which
heredity has played in forming the perceptive faculty of the
individual prior to its own experience. We have already seen that
heredity plays an important part in forming memory of ancestral
experiences, and thus it is that many animals come into the world with
their power of perception already largely developed. . . . The wealth
of ready-formed information, and therefore of ready-made powers of
perception, with which many newly-born or newly-hatched animals are
provided, is so great and so precise that it scarcely requires to be
supplemented by the subsequent experience of the individual." {233a}
