“I have the right to do whatever I wish with my property. If I own a pile of wood, I can set fire to it even if it is currently nailed together in the shape of a barn. Cigarettes may not be healthy for me in the long run, but I have the freedom to smoke them anyway. Drinking alcohol may or may not have negative side effects, but even if it does, the government has no authority to prohibit you from consuming it, even if it is "in your own best interest." Since when do we let the government decide what is or isn't good for us? What the hell does Congress know about nutrition, anyway? (For that matter, what does Congress know about the Constitution?) If the government can use force whenever something is "in our best interest" then government should force everyone to wake up at 6am every morning for calisthenics in the front yard. Fast food establishments should be torn down and replaced with bars that serve carrot juice and alfalfa sprouts, since - "it's in your best interest."”

"Introduction" to The Best of Isaac Asimov (1973)<!-- , p. ix -->
The Last Question (1956)
Context: "The Last Question" is my personal favorite, the one story I made sure would not be omitted from this collection. Why is it my favorite? For one thing I got the idea all at once and didn't have to fiddle with it; and I wrote it in white-heat and scarcely had to change a word. This sort of thing endears any story to any writer.
Then, too, it has had the strangest effect on my readers. Frequently someone writes to ask me if I can give them the name of a story, which they think I may have written, and tell them where to find it. They don't remember the title but when they describe the story it is invariably "The Last Question". This has reached the point where I recently received a long-distance phone call from a desperate man who began, "Dr. Asimov, there's a story I think you wrote, whose title I can't remember—" at which point I interrupted to tell him it was "The Last Question" and when I described the plot it proved to be indeed the story he was after. I left him convinced I could read minds at a distance of a thousand miles.
No other story I have written has anything like this effect on my readers — producing at once an unshakeable memory of the plot and an unshakeable forgettery of the title and even author. I think it may be that the story fills them so frighteningly full, that they can retain none of the side-issues.

God and the State (1871; publ. 1882)
Context: Does it follow that I reject all authority? Far from me such a thought. In the matter of boots, I refer to the authority of the bootmaker; concerning houses, canals, or railroads, I consult that of the architect or engineer. For such or such special knowledge I apply to such or such a savant. But I allow neither the bootmaker nor the architect nor the savant to impose his authority upon me. I listen to them freely and with all the respect merited by their intelligence, their character, their knowledge, reserving always my incontestable right of criticism and censure. I do not content myself with consulting authority in any special branch; I consult several; I compare their opinions, and choose that which seems to me the soundest. But I recognize no infallible authority, even in special questions; consequently, whatever respect I may have for the honesty and the sincerity of such or such an individual, I have no absolute faith in any person. Such a faith would be fatal to my reason, to my liberty, and even to the success of my undertakings; it would immediately transform me into a stupid slave, an instrument of the will and interests of others.

Introducing "Who by Fire"
Warsaw concert (1985)
Context: I come from a country where we do not have the same struggles as you have. I respect your struggles. And it may surprise you, but I respect both sides of this struggle. It seems to be that in Europe there needs to be a left foot and a right foot to move forward. I wish that both feet move forward and the body moves towards its proper destiny. This is an intense country; the people are heroic, the spirit is independent. It is a difficult country to govern, it needs a strong government and a strong union. … I would like to say to you, to the leaders of the left, and the leaders of the right, I sing... I sing for everyone. My song has no flag, my song has no party. And I say the prayer, that we said in our synagogue, I say it for the leader of your union and the leader of your party. May the Lord put a spirit, a wisdom and understanding into the hearts of your leaders and into the hearts of all their counsellors.

Paris Review Interview (1990)
Context: I know when it’s the best I can do. It may not be the best there is. Another writer may do it much better. But I know when it’s the best I can do. I know that one of the great arts that the writer develops is the art of saying, No. No, I’m finished. Bye. And leaving it alone. I will not write it into the ground. I will not write the life out of it. I won’t do that.
