“There are two tragedies in life. One is to lose your heart's desire. The other is to gain it.”
― George Bernard Shaw, Man and Superman

“It is what you read when you don't have to that determines what you will be when you can't help it.”
― Oscar Wilde

“True ignorance is not the absence of knowledge, but the refusal to acquire it.”
― Karl R. Popper

“I would never die for my beliefs because I might be wrong.”
― Bertrand Russell

“Epicurus's old questions are still unanswered: Is he (God) willing to prevent evil, but not able? then he is impotent. Is he able, but not willing? then he is malevolent. Is he both able and willing? then whence evil?”
― David Hume

“A thing is not necessarily true because a man dies for it.”
― Oscar Wilde

“It is impossible for us to think of any thing, which we have not antecedently felt, either by our external or internal senses.”
― David Hume, An Enquiry Concerning Human Understanding

“To define is to limit.”
― Oscar Wilde, The Picture of Dorian Gray

“Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever the universe has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved?”
― Carl Sagan

“Physics is like sex: sure, it may give some practical results, but that's not why we do it.”
― Richard P. Feynman

“Extraordinary claims require extraordinary evidence.”
― Carl Sagan

“For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.”
― Carl Sagan, The Demon-Haunted World: Science as a Candle in the Dark

“Any sufficiently advanced technology is indistinguishable from magic.”
― Arthur C. Clarke, Profiles of the Future: An Inquiry into the Limits of the Possible

“You never change things by fighting the existing reality.
To change something, build a new model that makes the existing model obsolete.”
― Buckminster Fuller

“Beware the irrational, however seductive. Shun the 'transcendent' and all who invite you to subordinate or annihilate yourself. Distrust compassion; prefer dignity for yourself and others. Don't be afraid to be thought arrogant or selfish. Picture all experts as if they were mammals. Never be a spectator of unfairness or stupidity. Seek out argument and disputation for their own sake; the grave will supply plenty of time for silence. Suspect your own motives, and all excuses. Do not live for others any more than you would expect others to live for you.”
― Christopher Hitchens, Letters to a Young Contrarian

“The problem, often not discovered until late in life, is that when you look for things in life like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people in life recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You'd be surprised how far that gets you.”
― Neil deGrasse Tyson

“I have a friend who's an artist and has sometimes taken a view which I don't agree with very well. He'll hold up a flower and say "look how beautiful it is," and I'll agree. Then he says "I as an artist can see how beautiful this is but you as a scientist take this all apart and it becomes a dull thing," and I think that he's kind of nutty. First of all, the beauty that he sees is available to other people and to me too, I believe. Although I may not be quite as refined aesthetically as he is ... I can appreciate the beauty of a flower. At the same time, I see much more about the flower than he sees. I could imagine the cells in there, the complicated actions inside, which also have a beauty. I mean it's not just beauty at this dimension, at one centimeter; there's also beauty at smaller dimensions, the inner structure, also the processes. The fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting; it means that insects can see the color. It adds a question: does this aesthetic sense also exist in the lower forms? Why is it aesthetic? All kinds of interesting questions which the science knowledge only adds to the excitement, the mystery and the awe of a flower. It only adds. I don't understand how it subtracts.”
― Richard P. Feynman, The Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman

“Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.”
― Lawrence M. Krauss

“Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?”
― Stephen Hawking, A Brief History of Time

“We can judge our progress by the courage of our questions and the depth of our answers, our willingness to embrace what is true rather than what feels good.”
― Carl Sagan

“Study hard what interests you the most in the most undisciplined, irreverent and original manner possible.”
― Richard Feynmann

“Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.”
― Richard P. Feynman

“I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here. I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell.”
― Richard P. Feynman

“What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.”
― Richard P. Feynman, QED: The Strange Theory of Light and Matter

“I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.”
― Richard P. Feynman

“Physics is to math what sex is to masturbation.”
― Richard Feynman

“I would rather have questions that can't be answered than answers that can't be questioned.”
― Richard Feynman

“Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination - stuck on this carousel my little eye can catch one - million - year - old light. A vast pattern - of which I am a part... What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?”
― Richard Feynman

“It doesn't seem to me that this fantastically marvelous universe, this tremendous range of time and space and different kinds of animals, and all the different planets, and all these atoms with all their motions, and so on, all this complicated thing can merely be a stage so that God can watch human beings struggle for good and evil - which is the view that religion has. The stage is too big for the drama.”
― Richard P. Feynman

“I don't know what's the matter with people: they don't learn by understanding, they learn by some other way — by rote or something. Their knowledge is so fragile!”
― Richard Feynman
