The age of the pulp magazine was the last in which youngsters, to get their primitive material, were forced to be literate.

The Imperial forces must keep their hands off, but they find that they can do much even so. Each sector is encouraged to be suspicious of its neighbors. Within each sector, economic and social classes are encouraged to wage a kind of war with each other. The result is that all over Trantor it is...

There is nothing so eternally adhesive as the memory of power.

Every vice of the Empire has been repeated in the Foundation. Inertia! Our ruling class knows one law; nochange. Despotism! They know one rule; force. Maldistribution! They know one desire; to hold what istheirs.

Many years later he looked through one of my books and said, “How did you learn all this, Isaac?””From you, Pappa”, I said.”From me? I don’t know any of this”.”You didn’t have to, Pappa”, I said. “You valued learning and you taught me to value it. Once I learned to value it, the rest came...

Fortran”. [M]ankind will suffer badly from the disease of boredom, a disease spreading more widely each year and growing in intensity. This will have serious mental, emotional and sociological consequences, and I dare say that psychiatry will be far and away the most important medical specialty in 2014. [T]he most glorious single word in the...

Any system which allows men to choose their own future will end by choosing safety and mediocrity, and in such a Reality the stars are out of reach.

In all the known history of Mankind, advances have been made primarily in physical technology; in the capacity of handling the inanimate world about Man. Control of self and society has been left to to chance or to the vague gropings of intuitive ethical systems based on inspiration and emotion. As a result no culture...

It seems to me, Golan, that the advance of civilization is nothing but an exercise in the limiting of privacy.

To surrender to ignorance and call it God has always been premature, and it remains premature today.

Properly read, the Bible is the most potent force for atheism ever conceived.

I received the fundamentals of my education in school, but that was not enough. My real education, the superstructure, the details, the true architecture, I got out of the public library. For an impoverished child whose family could not afford to buy books, the library was the open door to wonder and achievement, and I...

I am an atheist, out and out. It took me a long time to say it. I’ve been an atheist for years and years, but somehow I felt it was intellectually unrespectable to say one was an atheist, because it assumed knowledge that one didn’t have. Somehow, it was better to say one was a...

Once, when a religionist denounced me in unmeasured terms, I sent him a card saying, “I am sure you believe that I will go to hell when I die, and that once there I will suffer all the pains and tortures the sadistic ingenuity of your deity can devise and that this torture will continue...

In the empty expanses of space, the wandering traders need men like myself to care for the spiritual side of a life so given over to commerce, and worldly pursuits.

Having reached 451 books as of now doesn’t help the situation. If I were to be dying now, I would be murmuring, “Too bad! Only four hundred fifty-one.” (Those would be my next-to-last words. The last ones will be: “I love you, Janet.”) [They were. -Janet.]

It’s your fiction that interests me. Your studies of the interplay of human motives and emotion.

Stoop, then, or you will be beaten to your knees. Stoop voluntarily, and you may save a remnant. You have depended on metal and power and they have sustained you as far as they could. You have ignored mind and morale and they have failed you.

It is the writer who might catch the imagination of young people, and plant a seed that will flower and come to fruition.

I grow grandiose, which is a good sign I should become prosaic.

To [the government] it didn’t matter what happened to the American people as long as america in the abstract was kept strong.

To insult someone we call him ‘bestial’. For deliberate cruelty and nature, ‘human’ might be the greater insult.

It was obvious that bigotry was never a one-way operation, that hatred bred hatred!

I don’t believe in personal immortality; the only way I expect to have some version of such a thing is through my books.

What lasts in the reader’s mind is not the phrase but the effect the phrase created: laughter, tears, pain, joy. If the phrase is not affecting the reader, what’s it doing there? Make it do its job or cut it without mercy or remorse.

Of course there are worlds. Millions of them! Every star you see has worlds, and most of those you don’t see.

There was something ghost-like and insubstantial about gases to these early chemists. They called liquids that turned into gases easily, “spirits.” Methyl alcohol, they called “wood spirit”; ethyl alcohol, “wine spirit.” Even today, alcoholic beverages are frequently referred to as “spirits.” (Modern Arabs, from whose language the word “alcohol” was taken, call ethyl alcohol “spirit”...

All right, Schwartz, tackle my mind now. Go as deep as you want. I was born on Baronn in the Sirius Sector. I lived my life in an atmosphere of anti-Terrestrialism in the formative years, so I can’t help what flaws and follies lie at the roots of my subconscious. But look on the surface...

Whenever I have endured or accomplished some difficult task — such as watching television, going out socially or sleeping — I always look forward to rewarding myself with the small pleasure of getting back to my typewriter and writing something.

It pays to be obvious, especially if you have a reputation for subtlety.

When I read about the way in which library funds are being cut and cut, I can only think that American society has found one more way to destroy itself.

Meanwhile, fears of universal disaster sank to an all time low over the world.

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

It takes more than capital to swing business. You’ve got to have the A. I. D. degree to get by – Advertising, Initiative, and Dynamics.

Violence is the last refuge of the incompetent.

I do not fear computers. I fear the lack of them.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‘Eureka!’ but ‘That’s funny…’

The true delight is in the finding out rather than in the knowing.

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?

Don’t you believe in flying saucers, they ask me? Don’t you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death?No, I reply. No, no, no, no, and again no.One person recently, goaded into desperation by the litany of unrelieved negation, burst out “Don’t you believe in anything?”Yes”,...

I think you are wrong, partner Elijah. My briefing on human characteristics here among the people of Earth includes the information that, unlike the men of the Outer Worlds, they are trained from birth to accept authority. Apparently this is the result of your way of living. One man, representing authority firmly enough, was quite...

Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that ‘my ignorance is just as good as your knowledge.’

For a wise man, I have been told, once said, ‘Gratitude is best and most effective when it does not evaporate in empty phrases.’ But alas, my lady, I am but a mass of empty phrases, it would seem.
