Fever itself is Nature's instrument.

Acute [diseases] meaning those of which God is the author, chronic meaning those that originate in ourselves.

The generality have considered that disease is but a confused and disordered effort in Nature, thrown down from her proper state, and defending herself in vain.

In writing the history of a disease, every philosophical hypothesis whatsoever, that has previously occupied the mind of the author, should lie in abeyance.

Disease is nothing else but an attempt on the part of the body to rid itself of morbific matter.

I confidently affirm that the greater part of those who are supposed to have died of gout, have died of the medicine rather than the disease - a statement in which I am supported by observation.

Read Don Quixote; it is a very good book; I still read it frequently.
