“Never doubt that a small group of thoughtful, committed citizens can change the world”

Margaret Mead (1901-1978) was a well-known anthropologist who received degrees from Barnard College and Columbia University. She’s known today for a quotation she might not have said: “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.”
 
The quotation is in the theme of several of her writings, but the exact quotation hasn’t been found in any of them. The quotation has become popular since 1985, when it was cited (without a source) in books.
 
 
Wikipedia: Margaret Mead
Margaret Mead (December 16, 1901, Philadelphia – November 15, 1978, New York City) was an American cultural anthropologist, who was frequently a featured writer and speaker in the mass media throughout the 1960s and 1970s.
 
She was both a popularizer of the insights of anthropology into modern American and Western culture, and also a respected, if controversial, academic anthropologist. Her reports about the purportedly healthy attitude towards sex in South Pacific and Southeast Asian traditional cultures amply informed the 1960s sexual revolution. Mead was a champion of broadened sexual mores within a context of traditional western religious life.

Rev. Gerald L. Bucke, headmaster of Cushing Academy for Boys, Ashburnham, was the commencement speaker.
 
Rev. Bucke told the graduates that, while a small group cannot change the world, the important thing is to appreciate and live life as it is. He said it is important to “learn, love, laugh, and live.”

Margaret Mead: The making of an American icon
By Nancy C. Lutkehaus
Princeton, NJ: Princeton University Press
2008
Pg. 261:
“Never doubt that a small group of thoughtful committed citizens can cahgne the world; indeed, it’s the only thing that ever has.” There is a huge number of organizations and grassroots causes that use these words of Mead’s as an epigram, from the Cayuga Nation, a Native American group that is fighting to regain land in upstate New York, to the U.S. Environmental Protection Agency.”
 
Although the exact origins of the quote have not been located in any of Mead;s published work (some attribute it to the first Eart Day celebration in 1970, others think it may have first appeared in a newspaper article quoting Mead), the essence of the quote is directly related to the project Mead engaged in for The Wagon and the Star: A Study of American Community Initiative. The community projects analyzed in the book were exactly the type of small group, community0based, local endeavor that the quote refers to.
