I am looking for the person who said, "All that is needed for evil to thrive is for good people to do nothing." I have searched Bartlett's Familiar Quotations online, but with no success. Can you provide me with the answer or refer me to another site perhaps?
The quotation is usually attributed to Edmund Burke, although it has not been found in his writings. Webster's Dictionary of Quotations gives a slightly different version:
The only thing necessary for the triumph of evil is for good men to do nothing.
—The Fact Monster
