Our world faces a crisis as yet unperceived by those possessing power to make great decisions for good or evil. The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe. We scientists who released this immense power have an overwhelming responsibility in this world life-and-death struggle to harness the atom for the benefit of mankind and not for humanity's destruction. We need two hundred thousand dollars at once for a nation-wide campaign to let people know that a new type of thinking is essential if mankind is to survive and move toward higher levels. This appeal is sent to you only after long consideration of the immense crisis we face. ... We ask your help at this fateful moment as a sign that we scientists do not stand alone.
Variations of the quote:
"Problems cannot be solved by the same level of thinking that created them."
"No problem can be solved from the same level of consciousness that created it."
"The world will not evolve past its current state of crisis by using the same thinking that created the situation."
"The significant problems we have cannot be solved at the same level of thinking with which we created them."
"The world we have made, as a result of the level of thinking we have done thus far, creates problems we cannot solve at the same level of thinking at which we created them."
