Laymen are referred to frequently in this book because their work has been so helpful and important. Herbert Spencer and Alfred Russel Wallace had very clear conceptions regarding health. See their opinions regarding vaccination. There is no difference in the mental processes of physicians and laymen. Anyone can know about health, though it takes considerable experience and observation to get acquainted with the less important subject of disease. One indictment against medical men is that they have dwelled almost entirely on disease and paid no attention to health.
A group of modern men deserve great credit for popularizing health knowledge, which generally results in the loss of professional standing of the teacher. R. H. Trall, M. D., insisted that drugs are useless and harmful, that the only rational and safe way of healing ordinary ills is to use nature's means. "Strictly speaking, fever and food are antagonistic ideas," he wrote. In his Hydropathic Encyclopedia, copyrighted in 1851, he puts great stress on natural remedies, such as food and water. He met with much opposition, but he has left a deep impression on the minds of men who are now having some influence in shaping public opinion on health and healing.
Dr. Charles Page of Boston has been writing in advocacy of natural healing for over thirty years. He also has emphasized the harmfulness of drugs, the necessity of withholding food from fever patients, and simple living, remaining in touch with nature. Another important point which the doctor has been trying to impress upon the public is that it is necessary to retain the natural salts of the foods, instead of ruining them or throwing them away, as is generally done, especially in the preparation of vegetables and many cereal products.
Dr. Edward Hooker Dewey began to present his ideas to the public a few years after the Civil War. His little book entitled "The No-Breakfast Plan and the Fasting Cure," has had a great influence among rational healers. The doctor emphasized the importance of going without food in acute diseases so that no one who has read the book can forget it. He pointed out some of the errors of conventional healing as they had never been shown before, and I believe he was the first one to give the correct rules to guide people in the consumption of food.
For fourteen years Dr. J. H. Tilden of Denver has been a voluminous writer on health. He teaches that the law of compensation applies to health; that all disease is one and the same fundamentally; that "Autotoxemia is the fundamental basic cause of all diseases." Like all others who have investigated the subject impartially he believes that one of the most important factors of health is correct feeding. He allows all foods, in compatible combinations. Of course, he gives no drugs.
Dr. Harry Brook of Los Angeles is unique among the health educators of today. He is a brainy journalist with a good stock of fundamental health knowledge and is endowed with the ability to place his convictions before the public in a striking manner. He has been carrying on his educational work for many years.
Elbert Hubbard has also had a great deal of influence on the thought of today. At intervals he publishes an article on health which gets wide distribution. He has the faculty of making people think, and those who allow themselves to think independently generally evolve into serviceable knowledge.
Bernarr Macfadden has a large following. He is a strong advocate of physical culture and favors vegetarianism and other changes from conventional life. He educates his readers away from drugs. He has written much that is helpful and his influence is widely felt. Like all others who have struggled against the fetters of convention, he has aroused much opposition.
There are a few good health magazines, and there are many people living who deserve credit for their labor to improve the mental and physical condition of humanity. Some of these will be mentioned and quoted.
Some of the teachers have dwelled upon but one idea and some have advocated fallacies, but there is good to be found in all of them. No knowledge assays one hundred per cent. pure.
