Imagine a world where science and technology
Serve only to bring out the best in humanity.
Imagine a better world...Imagine peace on earth!
-- Robert Alan Silverstein

... if the society toward which we are developing is not to be a nightmare of exhaustion, we must use the interlude of the present era to develop a new technology which is based on a circular flow of materials such that the only sources of man's provisions will be his own waste products. -
-- Kenneth E. Boulding

As long as man was small in numbers and limited in technology, he could realistically regard the earth as an infinite reservoir, an infinite source of inputs and an infinite cesspool for outputs. Today we can no longer make this assumption. Earth has become a space ship, not only in our imagination but also in the hard realities of the social, biological, and physical system in which man is enmeshed. In what we might call the "old days," when man was small in numbers and earth was large, he could pollute it with impunity, though even then he frequently destroyed his immediate environment and had to move on to a new spot, which he then proceeded to destroy. Now man can no longer do this; he must live in the whole system, in which he must recycle his wastes and really face up to the problem of the increase in material entropy which his activities create. In a space ship there are no sewers.
-- Kenneth E. Boulding

Science can only ascertain what is, but not what should be, and outside of its domain value judgments of all kinds remain necessary.
-- Albert Einstein

The whole of science is nothing more than a refinement of everyday thinking.
-- Albert Einstein

* Medical science has proven time and again that when the resources are provided, great progress in the treatment, cure, and prevention of disease can occur.
~Michael J. Fox

Scientists, therefore, are responsible for their research, not only intellectually but also morally. This responsibility has become an important issue in many of today's sciences, but especially so in physics, in which the results of quantum mechanics and relativity theory have opened up two very different paths for physicists to pursue. They may lead us - to put it in extreme terms - to the Buddha or to the Bomb, and it is up to each of us to decide which path to take.
-- Fritjof Capra

What is a scientist after all? It is a curious man looking through a keyhole, the keyhole of nature, trying to know what's going on.
-- Jacques Cousteau

Think of it. We are blessed with technology that would be indescribable to our forefathers. We have the wherewithal, the know-it-all to feed everybody, clothe everybody, and give every human on Earth a chance. We know now what we could never have known before -- that we now have the option for all humanity to make it successfully on this planet in this lifetime. Whether it is to be Utopia or Oblivion will be a touch-and-go relay race right up to the final moment.
-- R. Buckminster Fuller

* "America has the technology and resources to meet all its energy needs while safeguarding the earth's climate. The urgent question now is, 'Do we have the will?' At least one city does, and I'm proud to live in it."
~ Denis Hayes

Reason, Observation, and Experience - the Holy Trinity of Science. 
~ Robert G. Ingersoll

Science may have found a cure for most evils; but it has found no remedy for the worst of them all -- the apathy of human beings.
-- Helen Keller

Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.
-- John F. Kennedy

Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.
-- Martin Luther King, Jr

* Massive poverty and obscene inequality are such terrible scourges of our times -- times in which the world boasts breathtaking advances in science, technology, industry and wealth accumulation -- that they have to rank alongside slavery and apartheid as social evils.
-- Nelson Mandela

* The good news is we have the technology and the tools to alleviate poverty on a global scale. All that is standing in our way is education and will.
-- Natalie Portman

* It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science. -- Carl Sagan

Science is not only compatible with spirituality; it is a profound source of spirituality. -- Carl Sagan

In science it often happens that scientists say, "You know that's a really good argument; my position is mistaken," and then they actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. -- Carl Sagan

Science is a way of thinking much more than it is a body of knowledge.
-- Carl Sagan

"A land ethic for tomorrow should be as honest as Thoreau's Walden, and as comprehensive as the sensitive science of ecology. It should stress the oneness of our resources and the live-and-help-live logic of the great chain of life."
~ Stewart Udall

We know from science that nothing in the universe exists as an isolated or independent entity.
-- Margaret J. Wheatley
