"I am incessantly led to make apology for the instability of the theories and practice of physic. Those physicians generally become the most eminent who have most thoroughly emancipated themselves from the tyranny of the schools of medicine. Dissections daily convince us of our ignorance of disease, and cause us to blush at our prescriptions. What mischiefs have we not done under the belief of false facts and false theories! We have assisted in multiplying diseases: we have done more, we have increased their fatality."—
"Some patients get well with the aid of medicine; more without it: and more in spite of it."
