"I watched what method Nature might take, with intention of subduing the symptom by treading in her footsteps"

This quote by Thomas Sydenham is describing the practice of medicine. He is recommending that rather of relying on standard approaches of treating symptoms, he instead observed how nature may take its course in order to control the sign. This is an example of the practice of naturalism, which is the belief that the body has the capability to heal itself and that the best method to deal with a symptom is to observe and follow the natural processes of the body. By observing nature, Sydenham had the ability to acquire insight into how the body works and how to finest treat it. He thought that by following nature's lead, he could better understand the body and its needs, and therefore be able to treat it more effectively. This quote is a testimony to Sydenham's belief in the power of naturalism and his commitment to understanding the body and its needs.
