"I should perhaps confess that on September 11 last, once I had experienced all the usual mammalian gamut of emotions, from rage to nausea, I also discovered that another sensation was contending for mastery. On examination, and to my own surprise and pleasure, it turned out be exhilaration. Here was the most frightful enemy–theocratic barbarism–in plain view….I realized that if the battle went on until the last day of my life, I would never get bored in prosecuting it to the utmost."
"I must say that I've always found the generational emphasis on the way that my youth was covered to be very annoying. There were a lot of other people born in April 1949, and I just don't feel like I have anything in common with most of them. I forget who it was who said that generation -- age group, in other words -- is the most debased form of solidarity. The idea of anyone who was born around that time having an automatic ticket to being called "a '60s person," is annoying to me."
"That phrase, "loss of innocence," has become stale with overuse and diminishing returns; no other culture is so addicted to this narcissistic impression of itself as having any innocence to lose in the first place."
"A great power imposes the obligation of exercising restraint, and we did not live up to this obligation. I think this affected many of the scientists in a subtle sense, and it diminished their desire to continue to work on the bomb."
"Suppose Germany had developed two bombs before we had any bombs. And suppose Germany had dropped one bomb, say, on Rochester and the other on Buffalo, and then having run out of bombs she would have lost the war. Can anyone doubt that we would then have defined the dropping of atomic bombs on cities as a war crime, and that we would have sentenced the Germans who were guilty of this crime to death at Nuremberg and hanged them? But, again, don't misunderstand me. The only conclusion we can draw is that governments acting in a crisis are guided by questions of expediency, and moral considerations are given very little weight, and that America is no different from any other nation in this respect."
"The most important step in getting a job done is the recognition of the problem. Once I recognize a problem I usually can think of someone who can work it out better than I could."
"A scientist's aim in a discussion with his colleagues is not to persuade, but to clarify."
"I'm looking for a market for wisdom."
"If we focus our attention on the next twenty-five years we may say that development is likely to reach some point intermediate between the first bomb detonated over Hiroshima and processes which once initiated might put an end to all life on earth. Just what intermediate point will be reached within twenty-five years no one can tell."
"Science is progressing at such a rapid rate that when you make a prediction and think you are ahead of your time by 100 years you may be ahead of your time by 10 at most."
"All we had to do was lean back, turn a switch and watch a screen of a television tube. If flashes of light appeared on the screen it would mean that liberation of atomic energy would take place in our lifetime. We turned the switch, saw the flashes — we watched for about five minutes — then switched everything off and went home. That night I knew the world was headed for trouble."
"A man's clarity of judgment is never very good when you're involved, and as you grow older, and as you grow more involved, your clarity of judgment suffers."
"Even if we accept, as the basic tenet of true democracy, that one moron is equal to one genius, is it necessary to go a further step and hold that two morons are better than one genius?"
"I sometimes have the feeling that I have lived through all this before and, in a sense, I have. I was sixteen years old when the first World War broke out, and I lived at that time in Hungary. From reading the newspapers in Hungary, it would have appeared that, whatever Austria and Germany did was right and whatever England, France, Russia, or America did was wrong. A good case could be made out for this general thesis, in almost every single instance. It would have been difficult for me to prove, in any single instance, that the newspapers were wrong, but somehow, it seemed to me unlikely that the two nations located in the center of Europe should be invariably right, and that all the other nations should be invariably wrong. History, I reasoned, would hardly operate in such a peculiar fashion, and it didn't take long until I began to hold views which were diametrically opposed to those held by the majority of my schoolmates."
"In order to succeed it is not necessary to be much cleverer than other people. All you have to do is be one day ahead of them."
"Even in times of war, you can see current events in their historical perspective, provided that your passion for the truth prevails over your bias in favor of your own nation."
"The people who have sufficient passion for the truth to give the truth a chance to prevail, if it runs counter to their bias, are in a minority. How important is this "minority?" It is difficult to say at this point, for, at the present time their influence on governmental decisions is not perceptible."
"I had not been long back from Hiroshima when I heard someone say, in Szilárd's presence; that it was the tragedy of scientists that their discoveries were used for destruction. Szilárd replied, as he more than anyone else had the right to reply; that it was not the tragedy of scientists, it is the tragedy of mankind."
"By the time his ideas became accepted he had already forged ahead to take up a new attitude. Szilard himself illustrated this characteristic in a story which he liked to tell about himself. He served once on a jury in a murder case. When the first vote was taken, eleven jurors were in favour of convicting, but one — Szilard — was for acquittal. Since unanimity was required, the discussion was resumed and Szilard expounded his arguments. After some time another vote was taken; the result was again eleven to one, but this time eleven were for acquittal, and one for conviction: the odd vote was Szilard’s who had in the meantime changed his mind!"
"After the war ended, partly disgusted by the cruel use to which his beloved physics had been put, Szilard left professional physics to explore new pastures – in his case, biology... there was a more pragmatic reason. As Szilard put it, this was an age when you took a year to discover something new in physics but only took a day to discover something new in biology."
"Another explanation for the failure of logic and observation alone to advance medicine is that unlike, say, politics, which uses a form of logic – mathematics – as its natural language, biology does not lend itself to logic. Leo Szilard, a prominent physicist, made this point when he complained that after switching from physics to biology he never had a peaceful bath again. As a physicist he would soak in the warmth of the bathtub and contemplate a problem, turn it in his mind, reason his way through it. But once he became a biologist, he constantly had to climb out of the bathtub to look up a fact."
"It is not necessary to succeed in order to persevere. As long as there is a margin of hope, however narrow, we have no choice but to base all our actions on that margin. America and Russia have one interest in common which may override all their other interests: to be able to live with the bomb without getting into an all-out war that neither of them wants."
"In life you must often choose between getting a job done or getting credit for it. In science, the most important thing is not the ideas you have but the decision which ones you choose to pursue. If you have an idea and are not doing anything with it, why spoil someone else's fun by publishing it?"
"For me, the idea of a creation is not conceivable without invoking the necessity of design. One cannot be exposed to the law and order of the universe without concluding that there must be design and purpose behind it all."
""In German or English, I know how to count down, und I'm learning Chinese" says Wernher von Braun."
""Once the rockets are up, who cares where they come down? That's not my department," says Wernher von Braun."
"One of the most disconcerting issues of our time lies in the fact that modern science, along with miracle drugs and communications satellites, has also produced nuclear bombs. What makes it even worse, science has utterly failed to provide an answer on how to cope with them. As a result, science and scientists have often been blamed for the desperate dilemma in which mankind finds itself today. Science, all by itself, has no moral dimension. The same poison-containing drug which cures when taken in small doses, may kill when taken in excess. The same nuclear chain reaction that produces badly needed electrical energy when harnessed in a reactor, may kill thousands when abruptly released in an atomic bomb. Thus it does not make sense to ask a biochemist or a nuclear physicist whether his research in the field of toxic substances or nuclear processes is good or bad for mankind. In most cases the scientist will be fully aware of the possibility of an abuse of his discoveries, but aside from his innate scientific curiosity he will be motivated by a deep-seated hope and belief that something of value for his fellow man may emerge from his labors. The same applies to technology, through which most advances in the natural sciences are put to practical use."
"Without wanting to seem overly partisan, I would like simply to point out that the space program has by all standards become America's greatest generator of new ideas in science and technology. It is essentially an organization for opening new frontiers, physically and intellectually. Today we live in a different world because in 1958 Americans accepted the challenge of space and made the required national investment to meet it. Young people today are learning a new science, but even more importantly, they are viewing the earth and man's relationship to it quite differently — and I think perhaps more humanly — than we did fifteen years ago. The space program is the first large scientific and technological activity in history that offers to bring the people of all nations together instead of setting them further apart."
"The body of knowledge is advancing at an absolutely incredible rate, and new tools are constantly being made available to the researcher that were previously not only unavailable, but often not even dreamed of."
"In this age of space flight, when we use the modern tools of science to advance into new regions of human activity, the Bible ... this grandiose, stirring history of the gradual revelation and unfolding of the moral law ... remains in every way an up-to-date book. Our knowledge and use of the laws of nature that enable us to fly to the Moon also enable us to destroy our home planet with the atom bomb. Science itself does not address the question whether we should use the power at our disposal for good or for evil. The guidelines of what we ought to do are furnished in the moral law of God. It is no longer enough that we pray that God may be with us on our side. We must learn again that we may be on God's side."
"The materialists of the nineteenth century and their Marxist heirs of the twentieth, tried to tell us that, as science gives us more knowledge about the creation, we could live without faith in a Creator. Yet so far, with every new answer, we have discovered new questions. The better we understand . . . the master plan for the galaxies, the more reason we have found to marvel at the wonder of God’s creation."
"Can a physicist visualize an electron? The electron is materially inconceivable and yet, it is so perfectly known through its effects that we use it to illuminate our cities, guide our airlines through the night skies and take the most accurate measurements. What strange rationale makes some physicists accept the inconceivable electrons as real while refusing to accept the reality of a Designer on the ground that they cannot conceive Him?"
"It is in scientific honesty that I endorse the presentation of alternative theories for the origin of the universe, life and man in the science classroom. It would be an error to overlook the possibility that the universe was planned rather than happening by chance."
"My experiences with science led me to God. They challenge science to prove the existence of God. But must we really light a candle to see the sun?"
"I'm convinced that before the year 2000 is over, the first child will have been born on the moon."
"If our intention had been merely to bring back a handful of soil and rocks from the lunar gravel pit and then forget the whole thing, we would certainly be history's biggest fools. But that is not our intention now — it never will be. What we are seeking in tomorrow's trip is indeed that key to our future on earth. We are expanding the mind of man. We are extending this God-given brain and these God-given hands to their outermost limits and in so doing all mankind will benefit. All mankind will reap the harvest. … What we will have attained when Neil Armstrong steps down upon the moon is a completely new step in the evolution of man."
"Science, by itself, has no moral dimension. The drug which cures when taken in small doses may kill when taken in excess. The nuclear energies that produce cheap electrical power when harnessed in a reactor may kill when abruptly released in a bomb. Thus, it does not make sense to ask a scientist whether his poison or his nuclear energy is “good” or “bad” for mankind."
"There is just one thing I can promise you about the outer-space program: Your tax dollar will go farther."
"We can lick gravity, but sometimes the paperwork is overwhelming."
"Everything in space obeys the laws of physics. If you know these laws, and obey them, space will treat you kindly. And don't tell me that man doesn't belong out there. Man belongs wherever he wants to go — and he’ll do plenty well when he gets there."
"Basic research is what I am doing when I don't know what I am doing."
"We knew that we had created a new means of warfare, and the question as to what nation, to what victorious nation we were willing to entrust this brainchild of ours was a moral decision more than anything else. We wanted to see the world spared another conflict such as Germany had just been through, and we felt that only by surrendering such a weapon to people who are guided by the Bible could such an assurance to the world be best secured."
"The rocket worked perfectly, except for landing on the wrong planet."
"A person who has been punished is not thereby simply less inclined to behave in a given way; at best, he learns how to avoid punishment."
"We admire people to the extent that we cannot explain what they do, and the word "admire" then means "marvel at.""
"Ethical control may survive in small groups, but the control of the population as a whole must be delegated to specialists—to police, priests, owners, teachers, therapists, and so on, with their specialized reinforcers and their codified contingencies."
"The real question is not whether machines think but whether men do. The mystery which surrounds a thinking machine already surrounds a thinking man."
"We shouldn't teach great books; we should teach a love of reading. Knowing the contents of a few works of literature is a trivial achievement. Being inclined to go on reading is a great achievement."
"Education is what survives when what has been learned has been forgotten."
"Let men be happy, informed, skillful, well behaved, and productive."
