There is sometimes more Skill shewed by a Physician in not Prescribing, than in Prescribing. And there is no better Remedy for some Diseases, than to let them alone : for unseasonable meddling with them, may hinder their proceeding to a Crisis, and at long Run they will mend of themselves.
Thomas Fuller, Introductio ad prudentiam (1727), pt. 2, aphorism 3064
