The more we study the anatomy, physiology and psychology of the human organism, the more we wonder at its marvelous complexity and ingenuity of structure and function. Every moment there are enacted in our bodies innumerable mechanical, chemical and psychological miracles. Who, or what, performs these miracles? We do not know. Yet every moment of our lives depends upon the infinite care and wisdom of this unknown intelligence and power. Why, then, should we not trust the One so faithful? Why should we not ask aid from One so powerful? Why not seek enlightenment from One who is so wise and so benevolent? However, not all of the human entity is dependent upon a controlling power, nor are all its functions involuntary. Within the house prepared by the Divine Intelligence, there dwells a sovereign in his own right and by his own might. He is endowed with freedom of desire, of choice and of action. He creates in his brain the nerve centers which control the voluntary activities of the body and from these brain centers he sends his commands through the fibers of the motor nerves to the voluntary muscles and makes them do his bidding; some he commands to walk, others to laugh, to eat, to speak, etc. This independent principle in man we call the ego, the individual intelligence. It imagines, desires, reasons, plans and works out, by the power of free will and independent choice, its own salvation or destruction, physically, mentally, morally and spiritually. By means of the motor nervous system, this thinker and doer directs and controls from the headquarters in the brain all the voluntary functions, capacities and powers of the human organism. This part of the human entity can evolve and progress only through its own conscious and voluntary personal efforts. In this, Man differs from the animal creation. The animal is able to take care of itself shortly after birth. It inherits, already fully developed, those brain centers for the control of the bodily functions which the newborn human must develop slowly and laboriously through patient and persistent effort in the course of many years. Of voluntary capacities and powers the newborn infant possesses little more than the simplest unicellular animalcule, that is, about all it can do is to scent and swallow food. Its cerebral hemispheres are as yet blank slates, to be inscribed gradually by its conscious and voluntary exertions. Before it can think, reason, speak, walk or do anything else, it must first develop in its brain special centers for each and every one of these voluntary faculties and functions. Through these persistent personal efforts, reason, will and self-control are gradually evolved and developed; while the animal, being hereditarily endowed with the faculties and functions necessary for the maintenance of life, has no occasion for the development of the higher faculties and powers and therefore remains an irresponsible automaton, which cannot be held accountable for its actions.
