Famous quotes containing the word medicine:
“God isn’t compatible with machinery and scientific medicine and universal happiness. You must make your choice. Our civilization has chosen machinery and medicine and happiness.”
—Aldous Huxley (1894–1963)
“I have noticed that doctors who fail in the practice of medicine have a tendency to seek one another’s company and aid in consultation. A doctor who cannot take out your appendix properly will recommend you to a doctor who will be unable to remove your tonsils with success.”
—Ernest Hemingway (1899–1961)
“Hygiene is the corruption of medicine by morality. It is impossible to find a hygienest who does not debase his theory of the healthful with a theory of the virtuous.... The true aim of medicine is not to make men virtuous; it is to safeguard and rescue them from the consequences of their vices.”
—H.L. (Henry Lewis)
