In sharp contrast to this state of oneness of the child's soul, in regard both to its own body and to the surrounding world, there stands the separatedness of the adult's intellectual consciousness, severed from both body and world. What happens to this part of the soul during its transition from one condition to the other may be aptly described by using a comparison from another sphere of natural phenomena. (Later descriptions in this book will show that a comparison such as the one used here is more than a mere external analogy.)
