More from William Harvey
"The circulation of the blood is a miracle of nature."
"The examination of the body after death is a most useful and necessary practice."
"It is not the strongest of the species that survives, nor the most intelligent, but the one most responsive to change."
"The left ventricle of the heart ejects blood into the aorta."
"I hold that the motion of the blood is in a circle, and is constantly impelled and distributed by the pulsific action of 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.
