"I have to chuckle sometimes when I am painted as "hard-nosed." In truth, our Justice Department wasn't nearly as aggressive as Roosevelt's. And our respect for civil liberties was far more extensive than the response following Pearl Harbor. Yes, we were tough, but we always operated within the law; it was never our policy or practice to detain any noncombatant without charges. In our conduct, we never approached the limits of the law as closely as Roosevelt did."

"Do not allow your sorrow or your rage to become hostility toward people on the basis of their ethnicity or their religious views. That is unacceptable; it is out of bounds, and if you break the law, we will prosecute you for it."

"Soldiers defending a country at war are not subject to the rules of procedure designed for court trials. For example, if a soldier encounters an enemy, under internationally agreed upon rules of war, that soldier can take whatever action is necessary to protect himself and neutralize his enemy, whether it involves capturing and detaining the enemy or killing him on the spot."

"Since lives and liberties depend upon clarity, not obfuscation, and reason, not hyperbole, let me take this opportunity today to be clear: Each action taken by the Department of Justice, as well as the war crimes commissions considered by the president and the Department of Defense, is carefully drawn to target a narrow class of individuals- terrorists. Our legal powers are targeted at terrorists. Our investigation is focused on terrorists. Our prevention strategy targets the terrorist threat."

"We need honest, reasoned debate; not fear-mongering. To those who pit Americans against immigrants, and citizens against non-citizens; to those who scare peace-loving people with phantoms of lost liberty; my message to you is this: Your tactics only aid terrorists- for they erode our national unity and diminish our resolve. They give ammunition to America's enemies, and pause to America's friends. They encourage people of good will to remain silent in the face of evil."

"Doing what is right in the face of adversity is not always easy or popular. Critics may assail you, but the critics don't always realize what they don't know or don't understand, because they don't have access to all the information."

"Some people in our country seem more concerned about respecting the dignity and privacy of criminals and terrorists than they are about having an airport full of people obliterated, or a completely booked hotel blown to bits. Perhaps they think, Let's not get so upset about attacks on our embassies or military bases. Maybe, they surmise, the terrorists have good reason for attacking us. We have no right to be harassing innocent people in our country. For some people, not even the grotesque images that filled our television screens after al Qaeda's blatant attacks on 9/11 seem enough to wake them out of their utopia feel-good world."

"How sad, that the group with the most access to the truth chose in several strategic instances to look the other way."

"Simply put, international terrorism made international cooperation mandatory rather than elective. Collective security has become the only real security against the hydra-headed monster of international terror."

"The goal of terror is not traditional territorial enlargement; rather the war target of the terrorist is the dismemberment of the will of the community it terrorizes."

"We must remain constantly vigilant. We dare not underestimate our enemy. Al Qaeda is committed to the destruction of America, and they are in it for the long haul. They are much smarter than many give them credit for being, and they are definitely much more patient than the pace of our fast-food society conditions us to be. Their commitment does not depend on bin Laden or any other single leader."

"recently the Attorney General made another astonishing claim, that there were Pakistani terrorists possibly coming on these boats from Haiti. No one has ever seen a Pakistani coming on a boat from Haiti yet. Ashcroft couldn’t even name one case."

"Former attorney general John Ashcroft mocked librarians and the ALA, accusing them and other administration critics of fueling "baseless hysteria" about the government's use of the PATRIOT Act to pry into the public's reading habits."

"The worst mistake a boss can make is not to say "well done"."

"The subject of this book is the structure of space-time on length-scales from 10-13cm, the radius of an elementary particle, up to 1028cm, the radius of the universe. ...we base our treatment on Einstein's General Theory of Relativity. This theory leads to two remarkable predictions about the universe: first, that the final fate of massive stars is to collapse behind an event horizon to form a 'black hole' which will contain a singularity; and secondly, that there is a singularity in our past which constitutes, in some sense, a beginning to the universe."

"I regard [the many worlds interpretation] as self-evidently correct. [T.F.: Yet some don't find it evident to themselves.] Yeah, well, there are some people who spend an awful lot of time talking about the interpretation of quantum mechanics. My attitude — I would paraphrase Goering—is that when I hear of Schrödinger's cat, I reach for my gun."

"Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws. It would therefore seem reasonable to suppose that there are also laws governing the boundary conditions."

"If you are disabled, it is probably not your fault, but it is no good blaming the world or expecting it to take pity on you. One has to have a positive attitude and must make the best of the situation that one finds oneself in; if one is physically disabled, one cannot afford to be psychologically disabled as well. In my opinion, one should concentrate on activities in which one's physical disability will not present a serious handicap. I am afraid that Olympic Games for the disabled do not appeal to me, but it is easy for me to say that because I never liked athletics anyway. On the other hand, science is a very good area for disabled people because it goes on mainly in the mind. Of course, most kinds of experimental work are probably ruled out for most such people, but theoretical work is almost ideal. My disabilities have not been a significant handicap in my field, which is theoretical physics. Indeed, they have helped me in a way by shielding me from lecturing and administrative work that I would otherwise have been involved in. I have managed, however, only because of the large amount of help I have received from my wife, children, colleagues and students. I find that people in general are very ready to help, but you should encourage them to feel that their efforts to aid you are worthwhile by doing as well as you possibly can."

"My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all."

"There ought to be something very special about the boundary conditions of the universe and what can be more special than that there is no boundary?"

"Einstein is the only figure in the physical sciences with a stature that can be compared with Newton. Newton is reported to have said "If I have seen further than other men, it is because I stood on the shoulders of giants." This remark is even more true of Einstein who stood on the shoulders of Newton. Both Newton and Einstein put forward a theory of mechanics and a theory of gravity but Einstein was able to base General Relativity on the mathematical theory of curved spaces that had been constructed by Riemann while Newton had to develop his own mathematical machinery. It is therefore appropriate to acclaim Newton as the greatest figure in mathematical physics and the Principia is his greatest achievement."

"What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary."

"We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special."

"On seeing the Enterprise's warp engine while visiting the set of Star Trek: The Next Generation (where he would briefly play himself in the 1993 episode Descent, Part I), Hawking smiled and said: I'm working on that."

"For millions of years, mankind lived just like the animals. Then something happened which unleashed the power of our imagination. We learned to talk and we learned to listen. Speech has allowed the communication of ideas, enabling human beings to work together to build the impossible. Mankind's greatest achievements have come about by talking, and its greatest failures by not talking. It doesn't have to be like this. Our greatest hopes could become reality in the future. With the technology at our disposal, the possibilities are unbounded. All we need to do is make sure we keep talking."

"These lectures have shown very clearly the difference between Roger and me. He's a Platonist and I'm a positivist. He's worried that Schrödinger's cat is in a quantum state, where it is half alive and half dead. He feels that can't correspond to reality. But that doesn't bother me. I don't demand that a theory correspond to reality because I don't know what it is. Reality is not a quality you can test with litmus paper. All I'm concerned with is that the theory should predict the results of measurements. Quantum theory does this very successfully. It predicts that the result of an observation is either that the cat is alive or that it is dead. It is like you can't be slightly pregnant: you either are or you aren't."

"So Einstein was wrong when he said, "God does not play dice." Consideration of black holes suggests, not only that God does play dice, but that he sometimes confuses us by throwing them where they can't be seen."

"I don't believe that the ultimate theory will come by steady work along existing lines. We need something new. We can't predict what that will be or when we will find it because if we knew that, we would have found it already! It could come in the next 20 years, but we might never find it."

"The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies. We are so insignificant that I can't believe the whole universe exists for our benefit. That would be like saying that you would disappear if I closed my eyes."

"I think computer viruses should count as life … I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image."

"It is not clear that intelligence has any long-term survival value."

"Einstein was confused, not the quantum theory."

"All my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them."

"A likely story — and probably true."

"The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological — technologies that flowed directly from advances in basic science."

"One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real. All one can do is find which mathematical models describe the universe we live in. It turns out that a mathematical model involving imaginary time predicts not only effects we have already observed but also effects we have not been able to measure yet nevertheless believe in for other reasons. So what is real and what is imaginary? Is the distinction just in our minds?"

"Although September 11 was horrible, it didn't threaten the survival of the human race, like nuclear weapons do."

"I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars."

"We shouldn't be surprised that conditions in the universe are suitable for life, but this is not evidence that the universe was designed to allow for life. We could call order by the name of God, but it would be an impersonal God. There's not much personal about the laws of physics."

"[on the possibility of contact with an alien civilization]: I think it would be a disaster. The extraterrestrials would probably be far in advance of us. The history of advanced races meeting more primitive people on this planet is not very happy, and they were the same species. I think we should keep our heads low."

"I have no idea. People who boast about their IQ are losers."

"Life would be tragic if it weren't funny."

"I am discounting reports of UFOs. Why would they appear only to cranks and weirdos?"

"My expectations were reduced to zero when I was 21. Everything since then has been a bonus."

"The life we have on Earth must have spontaneously generated itself. It must therefore be possible for life to generate spontaneously elsewhere in the universe."

"I'm sorry to disappoint science fiction fans, but if information is preserved, there is no possibility of using black holes to travel to other universes. If you jump into a black hole, your mass energy will be returned to our universe but in a mangled form which contains the information about what you were like but in a state where it can not be easily recognized. It is like burning an encyclopedia. Information is not lost, if one keeps the smoke and the ashes. But it is difficult to read. In practice, it would be too difficult to re-build a macroscopic object like an encyclopedia that fell inside a black hole from information in the radiation, but the information preserving result is important for microscopic processes involving virtual black holes."

"Evolution has ensured that our brains just aren't equipped to visualise 11 dimensions directly. However, from a purely mathematical point of view it's just as easy to think in 11 dimensions, as it is to think in three or four."

"I think that it's important for scientists to explain their work, particularly in cosmology. This now answers many questions once asked of religion."

"It is a waste of time to be angry about my disability. One has to get on with life and I haven't done badly. People won't have time for you if you are always angry or complaining."

"Equations are just the boring part of mathematics. I attempt to see things in terms of geometry."
