“Not all complex problems have easy solutions; so says science (so warns science.)”

“Science fiction writers foresee the inevitable, and although problems and catastrophes may be inevitable, solutions are not.”

“A science fiction story is a story built around human beings, with a human problem and a human solution, which would not have happened at all without its scientific content.”

“Like a work of art, we exceed our materials. Science needs art to frame the mystery, but art needs science so that not everything is a mystery. Neither truth alone is our solution, for our reality exists in plural”

“There is a new science of complexity which says that the link between cause and effect is increasingly difficult to trace; that change (planned or otherwise) unfolds in non-linear ways; that paradoxes and contradictions abound; and that creative solutions arise out of diversity, uncertainty and chaos.”

“Science is the search for the truth--it is not a game in which one tries to beat his opponent, to do harm to others. We need to have the spirit of science in international affairs, to make the conduct of international affairs the effort to find the right solution, the just solution of international problems, and not an effort by each nation to get the better of other nations, to do harm to them when it is possible. I believe in morality, in justice, in humanitarianism.”
