Or supposing that a child is born blind, or that some one of the nerve centers controlling certain faculties of the brain is absent, and the education is necessarily limited to the remaining nerve centers, is the soul still complete and perfect? Or in case of change of structure of the brain substance, as in softening of the brain; or in case of tumors, blood clots (thrombosis), or syphilitic disease, and paralysis either local or general resulting--depending on the seat of the disease--what has the soul to do with it? Or in disease of the meninges (coverings); or in case of insanity, whatever morbid cause might have produced that condition, where is the soul? Or when, in consequence of morbid changes, the mental and physical expressions, the actions, change, often extravagantly, is the soul affected thereby? When the body is afflicted with disease, does the soul suffer? At what period of fetal development is it that the soul enters the body? Or does it enter at birth? The breath of life is Oxygen. Without that element one could not live. Without it the newly born babe is more helpless than a lower animal. Not a single special sense is fully developed. The brain substance is not fully developed. The babe has no power to will anything. It has no volition--except the act of nursing, and that is not a voluntary act. The organs over which will has no control are the first to act--an infant soils its linen involuntarily. It imbibes nourishment, as a mass of protoplasm imbibes moisture. It has neither will power nor desire. It cannot select. It has neither knowledge nor conscience. Since none of the special senses is able to act, it has no perception of any kind whatsoever. It experiences only two sensations, pain and hunger. Young birds and other young animals do the same. Is there anything in this newly born babe of a supernatural character, such as a soul, spirit; the knowledge of God, or of good and evil? Does there exist in this mass of organized protoplasm anything that may be called divine? Is there aught innate? No! Certainly not!
