Since all these questions have been discussed often by practitioners, in many volumes and in large and contentious disputations, and the discussion continues, it remains to add such views as may seem nearest the truth. These are neither wholly in accord with one opinion or another, nor exceedingly at variance with both, but hold a sort of intermediate place between divers sentiments, a thing which may be observed in most controversies when men seek impartially for truth, as in the present case. For as regards the causes which either favour health or excite disease, how breath is drawn in or food distributed, not even philosophers attain to full knowledge, but seek it out by conjecture. But where there is no certain knowledge about a thing, mere opinion about it cannot find a certain remedy. And it is true that nothing adds more to a really rational treatment than experience. Although, therefore, many things, which are not strictly pertinent to the Arts as such, are yet helpful by stimulating the minds of those who practise them, so also this contemplation of the nature of things, although it does not make a practitioner, yet renders him more apt and perfected in the Art of Medicine. And it is probable that Hippocrates, Erasistratus and certain others, who were not content to busy themselves over fevers and ulcerations, but also to some extent searched into the nature of things, did not by this become practitioners, but by this became better practitioners. But reasoning is necessary to the Art of Medicine, not only when dealing with obscure causes, or natural actions, but often . . . for it is an art based on conjecture. However, in many cases not only does conjecture fail, but experience as well; and at times, neither fever, nor appetite, nor sleep follow their customary course. More rarely, yet now and again, a disease itself is new. That this does not happen is manifestly untrue, for in our time a lady, from whose genitals flesh had prolapsed and become gangrenous, died in the course of a few hours, whilst practitioners of the highest standing found out neither the class of malady nor a remedy. I conclude that they attempted nothing because no one was willing to risk a conjecture of his own in the case of a distinguished personage, for fear that he might seem to have killed, if he did not save her; yet it is probable that something might possibly have been thought of, had no such timidity prevailed, and perchance this might have been successful had one but tried it. In this sort of practice similarity is not always of service, and when it does prove serviceable, nevertheless there has been a process of reasoning, in the theorizing over similar classes of diseases and of remedies, as to which is the best remedy to use. When, therefore, such an incident occurs, the practitioner ought to arrive at something which may answer, even if perhaps not always, yet nevertheless more often than not. He will see, however, every novel plan, not from hidden things, for these are dubious and unascertainable, but from those which can be explored, that is, from evident causes. For what matters is this: whether fatigue or thirst, whether heat or cold, whether wakefulness or hunger, whether abundance in food or wine, whether intemperance in venery, has produced the disease. Nor should there be ignorance of the sick man's temperament; whether his body is rather humid or rather dry, whether his sinews are strong or weak, whether he is frequently or rarely ill; and when ill whether so severely or slightly, for a short or long while; the kind of life he has lived, laborious or quiet, accompanied by luxury or frugality. From such and similar data, one may often deduce a novel mode of treatment.
