In order for children and youth to have health, cheerfulness, vivacity, and well-developed muscles and brains, they should be much in the open air, and have well-regulated employment and amusement. Children and youth who are kept at school and confined to books cannot have sound physical constitutions. The exercise of the brain in study, without corresponding physical exercise, has a tendency to attract the blood to the brain, and the circulation of the blood through the system becomes unbalanced. The brain has too much blood, and the extremities too little. There should be rules regulating the studies of children and youth to certain hours, and then a portion of their time should be spent in physical labor. And if their habits of eating, dressing, and sleeping are in accordance with physical law, they can obtain an education without sacrificing physical and mental health.... CT 83.2
There should have been connected with the schools, establishments for carrying on various branches of labor, that the students might have employment and the necessary exercise out of school hours. The students’ employment and amusements should have been regulated with reference to physical law, and should have been adapted to preserve to them the healthy tone of all the powers of body and mind. Then a practical knowledge of business could have been obtained while their literary education was being gained. CT 83.3
Students at school should have had their moral sensibilities aroused to see and feel that society has claims upon them, and that they should live in obedience to natural law, so that they can, by their existence and influence, by precept and example, be an advantage and blessing to society. It should be impressed upon the youth that all have an influence that is constantly telling upon society, to improve and elevate, or to lower and debase. The first study of the young should be to know themselves and how to keep their bodies in health. CT 84.1
