“ If the completed organism does not lie as potency and promise in the germ and its natural environment, then where does it abide? If the qualities of the organism are not thus derived, then indeed is there something in man not derived from nature, just as a time-honored school of philosophy asserts. But for biology this would be vitalism, and vitalism means a walled city with the gates locked and the keys lost beyond recovery. ”
