Chapter 21—Study of Physiology

Since the mind and the soul find expression through the body, both mental and spiritual vigor are in great degree dependent on physical strength and activity. Whatever promotes physical health promotes the development of a strong mind and a well-balanced character. Without health no one can as distinctly understand or as completely fulfill his or her obligations to oneself, to other persons, or to the Creator. Therefore the health should be as faithfully guarded as the character. A knowledge of physiology and hygiene should be the basis of all educational effort.TEd 117.1

Though the facts of physiology are now generally understood, there is an alarming indifference in regard to the principles of health. Even of those who have a knowledge of these principles, few put them into practice.TEd 117.2

The youth, in the freshness and vigor of life, little realize the value of their abounding energy. A treasure more precious than gold, more essential to advancement than learning or rank or riches—how lightly it is held, how rashly squandered! Many men and women, sacrificing health in the struggle for riches or power, have almost reached the object of their desire, only to fall helpless, while others, possessing superior physical endurance, grasp the longed-for prize! Through morbid conditions, the result of neglecting the laws of health, many have been led into evil practices, to the sacrifice of every hope for this world and the next.TEd 117.3

In the study of physiology, pupils should be led to see the value of physical energy and how it can be preserved and developed to contribute in the highest degree to success in life’s great struggle.TEd 118.1
