Famous quotes containing the word medicine:
“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)
“As there is a use in medicine for poisons, so the world cannot move without rogues.”
—Ralph Waldo Emerson (1803–1882)
“We gave ‘em wings to fly and they rained death on us. We gave ‘em a voice to be heard around the world and they preach hatred to poison the minds of nations. Even the medicine we gave them to ease their pain is turned into a vice to enslave half mankind for the profit of a few. Ah, Janet, dear, don’t you see? Every gift that science has given them has been twisted into a thing of hate and greed.”
—Karl Brown (1897–1990)
