If in this hall there are medical men or brother chemists, I hope they will not think me their enemy. I am on the contrary their best friend. On the one hand I should like to see the theoretical and practical study of suggestion on the syllabus of the medical schools for the great benefit of the sick and of the doctors themselves; and on the other hand, in my opinion, every time that a patient goes to see his doctor, the latter should order him one or even several medicines, even if they are not necessary. As a matter of fact, when a patient visits his doctor, it is in order to be told what medicine will cure him. He does not realize that it is the hygiene and regimen which do this, and he attaches little importance to them. It is a medicine that he wants. In my opinion, if the doctor only prescribes a regimen without any medicine, his patient will be dissatisfied; he will say that he took the trouble to consult him for nothing, and often goes to another doctor. It seems to me then that the doctor should always prescribe medicines to his patient, and, as much as possible, medicines made up by himself rather than the standard remedies so much advertised and which owe their only value to the advertisement. The doctor's own prescriptions will inspire infinitely more confidence than So and So's pills which anyone can procure easily at the nearest drug store without any need of a prescription. HOW SUGGESTION WORKS In order to understand properly the part played by suggestion or rather by autosuggestion, it is enough to know that the _unconscious self is the grand director of all our functions_. Make this believed, as I said above, that a certain organ which does not function well must perform its function, and instantly the order is transmitted. The organ obeys with docility, and either at once or little by little performs its functions in a normal manner. This explains simply and clearly how by means of suggestion one can stop haemorrhages, cure constipation, cause fibrous tumours to disappear, cure paralysis, tubercular lesions, varicose, ulcers, etc.
