To a student or a literary man, it is easy to explain the necessity of the proper division of the nervous energies between the mind and the body. Any student or literary man who has a daily mental task to do, will do it before he exercises his body to any great extent. If I wished to unfit my mind for a day of literary labor, I would use the hoe in my garden for an early hour in the morning. If I wished utterly to unfit a pupil for his daily task of study, I would put him through an exhausting walk before breakfast. The direction of all the nervous energies to the support of the muscular system, and the necessary draft upon the digestive and nutritive functions to supply the muscular waste, leave the mind temporarily a bankrupt. I have never seen a man who was really remarkable for acquired muscular power, and, at the same time, remarkable for mental power. A man may be born into the world with a fine muscular system and a fine brain, and in early life his muscular system may have a fine development. Such a man may subsequently have a remarkable mental development, but this development will never be accompanied by large and regular expenditures of muscular power. If I wished to repress the mental growth and manifestation of a man, I would undertake to educate him up to the point of lifting eight or ten kegs of nails. There is danger at first of overdoing our "muscular Christianity"-- danger of getting more muscle than Christianity; and there is a good deal more danger of overdoing our muscular intellectuality. The difference between the kind and amount of exercise necessary to produce a healthy machine and the kind and amount necessary to produce a powerful one, is very great. We are never to look for great intellectuality in a professor of gymnastics, nor to expect that the time will come when a man will not only walk a thousand miles in a thousand hours, but compose a poem of a thousand lines at the same time.
