A scientist is as weak and human as any man, but the pursuit of science may ennoble him even against his will.Collection: Science
The young specialist in English Lit, ...lectured me severely on the fact that in every century people have thought they understood the Universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern "knowledge" is that it is wrong.Collection: People

There is no merit to discipline under ideal circumstances. I must have it in the face of death or it is worthless.Collection: Discipline
Although the time of death is approaching me, I am not afraid of dying and going to Hell or (what would be considerably worse) going to the popularized version of Heaven. I expect death to be nothingness and, for removing me from all possible fears of death, I am thankful to atheism.Collection: Death
The greatest inventors are unknown to us. Someone invented the wheel - but who?Collection: Wheels
Human beings thought with their hands. It was their hands that were the answer of curiosity, that felt and pinched and turned and lifted and hefted. There were animals that had brains of respectable size, but they had no hands and that made all the difference.Collection: Animal
I prefer rationalism to atheism. The question of God and other objects-of-faith are outside reason and play no part in rationalism, thus you don't have to waste your time in either attacking or defending.Collection: Play
Working ten hour days allows you to fall behind twice as fast as you could working five hour days.Collection: Fall

Despite all that education and experience can do, I retain a certain level of unsophistication that I cannot eradicate and that my friends find amusing. In fact, I think I sometimes detect conspiratorial plottings among my friends to protect me against my own lack of sophistication. I don't mind. I suspect that I am never quite as unsophisticated as they think I am, but I don't mind.Collection: Thinking
They absorb carbon monoxide and carbon dioxide and give out oxygen. What could be more desirable? And they look good in the bargain. Stop chopping down the rain forests and plant more saplings, and we're on our way.Collection: Rain
Gratitude is best and most effective when it does not evaporate itself in empty phrases.Collection: Gratitude
There are so many benefits to be derived from space exploration and exploitation; why not take what seems to me the only chance of escaping what is otherwise the sure destruction of all that humanity has struggled to achieve for 50,000 years?Collection: Moon

To all my gentle readers who have treated me with love for over 30 years, I must say farewell. It has always been my ambition to die in harness with my head face down on a keyboard and my nose caught between two of the keys, but that's not the way it worked out. I have had a long and happy life and I have no complaints about the ending, thereof, and so farewell - farewell.Collection: Farewell

Politically popular speech has always been protected: even the Jews were free to say ‘Heil Hitler.’Collection: Speech
The appearance of strength is all about you. It would seem to last forever. However... the rotten tree-trunk, until the very moment when the storm-blast breaks it in two, has all the appearance of might it ever had. The storm-blast whistles through the branches of the Empire even now. Listen... and you will hear the creaking.Collection: Two
Married life had taught Toran the futility of arguing with a female in a dark-brown mood.Collection: Marriage
Speech, originally, was the device whereby Man learned, imperfectly, to transmit the thoughts and emotions of his mind. By setting up arbitrary sounds and combinations of sounds to represent certain mental nuances, he developed a method of communication--but one which in its clumsiness and thick-thumbed inadequacy degenerated all the delicacy of the mind into gross and guttural signaling.Collection: Communication
All the hundreds of millions of people who, in their time, believed the Earth was flat never succeeded in unrounding it by an inch.Collection: People
And [Asimov]'ll sign anything, hardbacks, softbacks, other people's books, scraps of paper. Inevitably someone handed him a blank check on the occasion when I was there, and he signed that without as much as a waver to his smile — except that he signed: 'Harlan Ellison.Collection: Book
The fundamentalists deny that evolution has taken place; they deny that the earth and the universe as a whole are more than a few thousand years old, and so on. There is ample scientific evidence that the fundamentalists are wrong in these matters, and that their notions of cosmogony have about as much basis in fact as the Tooth Fairy has.Collection: Taken

A myth or legend is simply not made up out of a vacuum. Nothing is--or can be. Somehow there is a kernel of truth behind it, however distorted that might be.Collection: Vacuums
Oh, for a pin that would puncture pretension!Collection: Humble
I wish that I could say I was optimistic about the human race. I love us all, but we are so stupid and shortsighted that I wonder if we can lift our eyes to the world about us long enough not to commit suicide.Collection: Suicide

Intelligence is an extremely subtle concept. It's a kind of understanding that flourishes if it's combined with a good memory, but exists anyway even in the absence of good memory. It's the ability to draw consequences from causes, to make correct inferences, to foresee what might be the result, to work out logical problems, to be reasonable, rational, to have the ability to understand the solution from perhaps insufficient information. You know when a person is intelligent, but you can be easily fooled if you are not yourself intelligent.Collection: Memories
I have been told that a young would-be composer wrote to Mozart asking advice about how to compose a symphony. Mozart responded that a symphony was a complex and demanding form and it would be better to start with something simpler. The young man protested, 'But, Herr Mozart, you wrote symphonies when you were younger than I am now.' Mozart replied, 'I never asked how.Collection: Men

Congratulations on the new library, because it isn't just a library. It is a space ship that will take you to the farthest reaches of the Universe, a time machine that will take you to the far past and the far future, a teacher that knows more than any human being, a friend that will amuse you and console you-and most of all, a gateway, to a better and happier and more useful life.Collection: Teacher
When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together.Collection: Atheist
Jokes of the proper kind, properly told, can do more to enlighten questions of politics, philosophy, and literature than any number of dull arguments.Collection: Wise
It is no defense of superstition and pseudoscience to say that it brings solace and comfort to people. . . . If solace and comfort are how we judge the worth of something, then consider that tobacco brings solace and comfort to smokers; alcohol brings it to drinkers; drugs of all kinds bring it to addicts; the fall of cards and the run of horses bring it to gamblers; cruelty and violence bring it to sociopaths. Judge by solace and comfort only and there is no behavior we ought to interfere with.Collection: Running

It is the obvious which is so difficult to see most of the time. People say 'It's as plain as the nose on your face.' But how much of the nose on your face can you see, unless someone holds a mirror up to you?Collection: Mirrors
There’s nothing to it. All you have to do is take a close look at yourself and you will understand everyone else. We’re in no way different ourselves... You show me someone who can’t understand people and I’ll show you someone who has built up a false image of himself.Collection: People

Happiness is doing it rotten your own way.Collection: Rotten
To me it seems to be important to believe people to be good even if they tend to be bad, because your own joy and happiness in life is increased that way, and the pleasures of the belief outweigh the occasional disappointments. To be a cynic about people works just the other way around and makes you incapable about enjoying the good things.Collection: Disappointment
