No helpful healing knowledge should be kept away from the public; it should be as free as possible. The public, when it understands, willingly pays a fair price for it, which is all that should be asked. To take advantage of the sick and helpless is contemptible. The old-time idea, still prevalent, that medical knowledge is for the doctor only is a mistake. The best patients are the intelligent ones. The office of the physician should be to educate his clients; his best knowledge and his best qualities will be developed in dealing honestly with intelligent people. The practice of medical secrecy began in ancient times when the healers and the priests believed in fooling the public. Unfortunately, this professional attitude still survives. No one who has not practiced the healing art can know how tempted a doctor is to fake and humbug a little to retain and gain patronage. Emerson wrote: "He is the rich man who can avail himself of other men's faculties. He is the richest man who knows how to draw a benefit from the labors of the greatest number of men--of men in distant countries and past times." Those who wish to be healthy and efficient are compelled to advance by taking advantage of other men's faculties. He who attempts to learn all by experience does not live long enough to travel far. Everyone should try to get a knowledge of the few most fundamental facts of nature governing life. Then it would not be so easy to go astray. Health literature should be read with an open mind. Read in conjunction with your knowledge of the laws of nature, and then it will be seen that health and disease are according to law, and that by eliminating the mistakes disease will disappear. All disease is one. It is the manifestation of disobeyed natural law, and whether the mistakes are made knowingly or ignorantly matters but little so far as the results are concerned. It is generally considered a disgrace to be imprisoned for transgressing man-made law, which is faulty and complex. How about being in the fetters of disease for disregarding nature's law, which is just and simple? It is my aim to use as simple language as possible. If physicians read these pages, they will understand them without technicalities, and so will laymen. This book contains much knowledge that physicians should have, knowledge that will help them when that which they have acquired from conventional sources fails, but in many respects it is so opposed to popular customs and beliefs that many physicians will doubtless condemn it on first reading. Doctors are taught otherwise at medical colleges, and most of them have such high regard for authority that it is very difficult for them to see matters in a different light. I appeal to both laymen and healers with open minds.
