Hummanın Bilinmezliği ve Dört Hılt Öğretisinin Çöküşü

Both the true nature of fevers and their remedies have remained unknown until now. I therefore published a book to establish this fact; but it was so scattered with errors from the printer that I would blush to acknowledge it as my own. Yet, even as it was, because of the novelty of the subject, it began to be sought after almost as soon as it appeared, for the supply had run out. For I demonstrate that fever is misunderstood and its remedies unknown; likewise, that the theory of the four humors consists of old wives' tales, with which gullible mortals are still fattening graveyards today. Therefore, let this be the Problem: Either I myself have erred completely in this matter, or indeed I have not, and it is the Humorists who have erred. The entire Humoristic School has gone to ruin, for the very hinge upon which the doorposts of healing rest now lies broken. Since this matter touches upon life itself, the State, and most families, I ask the Christian world, out of charity, to watch over the decision of this unexpected and momentous problem.
