"Perhaps," my companion resumed, "a more important negative factor in the improvement in medical and hygienic conditions than any I have mentioned is the fact that people are no longer in the state of ignorance as to their own bodies that they seem formerly to have been. The progress of knowledge in that respect has kept pace with the march of universal culture. It is evident from what we read that even the cultured classes in your day thought it no shame to be wholly uninformed as to physiology and the ordinary conditions of health and disease. They appear to have left their physical interests to the doctors, with much the same spirit of cynical resignation with which they turned over their souls to the care of the clergy. Nowadays a system of education would be thought farcical which did not impart a sufficient knowledge of the general principles of physiology, hygiene, and medicine to enable a person to treat any ordinary physical disturbance without recourse to a physician. It is perhaps not too much to say that everybody nowadays knows as much about the treatment of disease as a large proportion of the members of the medical profession did in your time. As you may readily suppose, this is a situation which, even apart from the general improvement in health, would enable the people to get on with one physician where a score formerly found business. We doctors are merely specialists and experts on subjects that everybody is supposed to be well grounded in. When we are called in, it is really only in consultation, to use a phrase of the profession in your day, the other parties being the patient and his friends. "But of all the factors in the advance of medical science, one of the most important has been the disappearance of sectarianism, resulting largely from the same causes, moral and economic, which banished it from religion. You will scarcely need to be reminded that in your day medicine, next to theology, suffered most of all branches of knowledge from the benumbing influence of dogmatic schools. There seems to have been well-nigh as much bigotry as to the science of curing the body as the soul, and its influence to discourage original thought and retard progress was much the same in one field as the other.
