More from William Harvey
"The art of medicine is to prolong life, not to shorten it."
"As art is a habit with reference to things to be done, so is science a habit in respect to things to be known."
"The heart is the sun of the microcosm."
"I have not hesitated to present to you, my dear reader, the results of my anatomical observations."
"The arteries are the channels through which the blood is driven from the heart."
About William Harvey (1578-1657)
English physician whose On the Motion of the Heart and Blood in Animals (1628) demonstrated blood circulation, overturning 1,400 years of Galenic medicine. Closely associated with Francis Bacon (his contemporary in the new English empiricism). For an intellectual contrast, see Galenic medicine, the 2nd-century Greek medical tradition (humors, blood-as-consumed-fuel) — Harvey calculated that the heart pumps more blood per hour than the body could possibly produce as fuel — a single quantitative observation that demolished the entire Galenic-Aristotelian medical worldview. The cleanest example in medical history of arithmetic disproving 14 centuries of authority.
