“In order to assure a certain progress in this reading, consider what hours you have free from the school and the exercises of the school. Give about two of them, every day, to exercise; for health must not be sacrificed to learning. A strong body makes the mind strong. As to the species of exercise, I advise the gun. While this gives a moderate exercise to the body, it gives boldness, enterprise, and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body, and stamp no character on the mind. Let your gun therefore be the constant companion of your walks. Never think of taking a book with you. The object of walking is to relax the mind. You should therefore not permit yourself even to think while you walk; but divert your attention by the objects surrounding you. Walking is the best possible exercise. Habituate yourself to walk very far. The Europeans value themselves on having subdued the horse to the uses of man; but I doubt whether we have not lost more than we have gained, by the use of this animal. No one has occasioned so much, the degeneracy of the human body. An Indian goes on foot nearly as far in a day, for a long journey, as an enfeebled white does on his horse; and he will tire the best horses. There is no habit you will value so much as that of walking far without fatigue. I would advise you to take your exercise in the afternoon: not because it is the best time for exercise, for certainly it is not; but because it is the best time to spare from your studies;”
Thomas Jefferson, Letter to Peter Carr, August 19, 1785
Of course, we don’t need a gun to walk. The physical exercise is the key.
He’d be horrified by our current situation; obesity, carbon emissions, and oil prices and politics all plaguing us when the ability of “walking far without fatigue” was his ideal. How far we’ve come from horses!
Because most of us do not study so intensely these days that we need a mental break, I like to will combine the walking, the reading breaks, and the discussions.
