" He who considers disease results to be the disease itself, and expects to do away with these as disease, is insane. It is an insanity in medicine, an insanity that has grown out of the milder forms of mental disorder in science, crazy whims. The bacteria are results of disease. In the course of time we will be able to show perfectly that the microscopical little fellows are not the disease cause, but that they come after, that they are scavengers accompanying the disease, and that they are perfectly harmless in every respect. They are the outcome of the disease, are present wherever the disease is, and by the microscope it has been discovered that every pathological result has its corresponding bacteria. The Old School consider these the cause, but we will be able to show that disease cause is much more subtle than anything that can be shown by a microscope. We will be able to show you by a process of reasoning, step by step, the folly of hunting for disease cause by the implements of the senses.
