Buckminster Fuller (1895-1983) was an American designer and futurist best known for popularizing the geodesic dome. Wikipedia says,
"Though Fuller was concerned about sustainability and human survival under the existing socio-economic system, he remained optimistic about humanity's future." (Wikipedia: Buckminster Fuller, 8.21.21 UTC 12:06)
The rest of this post is some quotes from Fuller.
Education
"Education by choice, with its marvelous motivating psychology of desire for truth, will make life ever cleaner and happier, more rhythmical and artistic." (4D Time Lock, 1928)
"Quite clearly, our task is predominantly metaphysical, for it is how to get all of humanity to educate itself swiftly enough to generate spontaneous social behaviors that will avoid extinction." (Synergetics: Explorations in the Geometry of Thinking, 1975)
"You cannot change how someone thinks, but you can give them a tool to use which will lead them to think differently." (AZQuotes.com)
"Don't attempt to reform man. An adequately organized environment will permit humanity's original, innate capabilities to become successful." (AZQuotes.com)
"Out of my general world-pattern-trend studies, there now comes strong evidence that nothing is going to be quite so surprising and abrupt in the future history of man as the forward evolution in the educational process." (AZQuotes.com)
Sustainability
"Architects, if they are really to be comprehensive, must assume the enormous task of thinking in terms always disciplined to the scale of the total world pattern of needs, its resource flows, its recirculatory and regenerative processes." (Ideas and Integrities, 1963)
"There is an inherently minimum set of essential concepts and current information, cognizance of which could lead to our operating our planet Earth to the lasting satisfaction and health of all humanity." (Synergetics: Explorations in the Geometry of Thinking, 1975)
"We are not going to be able to operate our Spaceship Earth successfully nor for much longer unless we see it as a whole spaceship and our fate as common. It has to be everybody or nobody." (World Game Series: Document 1, 1961)
Labor
"We must do away with the absolutely specious notion that everybody has to earn a living. It is a fact today that one in ten thousand of us can make a technological breakthrough capable of supporting all the rest." (Quoted in The New York Magazine Environment Teach-In, 1970)
"U.S. labor leaders will realize that automation can multiply man's wealth far more rapidly than it is multiplying at present and that automation will leave all men free to search and research." (AZQuotes.com)
