The regular [physician] and I sit down by a patient. He takes her by the hand, and so do I. He feels the pulse to ascertain the peculiar vibration and number of beats in a given time. This to him is knowledge. To me it is all quackery or ignorance. He looks at the tongue as though it contained information.
To me this is all folly and ignorance. He then begins to ask questions, which contain nothing to me, because [this questioning] is of no force. All this is shaken up in his head, and comes forth in the form of a disease, which is all error to me, and I will give you the diagnosis of this error.
The feeling of the pulse is to affect the patient so he will listen to the doctor. Examining the tongue is all for effect. The peculiar cast of the doctor's head is the same. The questions, accompanied by certain looks and gestures, are all to get control of the patient's mind so as to produce an impression. Then he looks very wise, and so on. All the symptoms put together show no knowledge, but a lack of wisdom, and the general credulity of mankind rendering [people] liable to be humbugged by any person however ignorant he may be, if he has the reputation of possessing all medical knowledge.
Now, sir, this is the field you are about to enter, and you will find the hardest stumbling block from diplomas. Greek and Latin, and the like are all of no consequence to the sick. It is impossible to give you even a mere shadow of twenty years' experience. But I may be of some use to you. I will say a word or two on the old practice, (not taking much time,) that will answer all your questions on the old school; for the less you know the better.
Watch the popular physician. See his shrewdness. Watch the sick patient: nervous and trembling like a person in the hands of a magistrate who has him in his power, and whose real object is to deceive him. See the two together, one perfectly honest, and the other, if honest, perfectly ignorant, [the physician] undertaking blindfolded to lead the patients through the dark valley of the shadow of death, the patient being born [mentally] blind. Then you see them going along, and at last they both fall into the ditch.
Now, like the latter, do not deceive your patients. Try to instruct them, and correct their errors. Use all the wisdom you have, and expose the hypocrisy of the profession in any one. Never deceive your patients behind their backs. Always
