Extended excerpt  [Letter excerpt – Chapter 38. Full excerpt cited from selection of nearly “45,000 carbons” [copies] of letters from Asimov that his brother, Stanley Asimov, reviewed after his death. In his introduction to Yours, Isaac Asimov, Asimov noted that “…because the contents of the letters stand on their own merits, I have omitted the names of the recipients. Only in those cases where it's vital to understanding the letters have I indicated to whom the letter was written.” (p. xiii)]:

“I don't subscribe to the thesis, “Let the buyer beware.” I prefer the disregarded one that goes, “Let the seller be honest.”

Extended excerpt:

“Step 6 – A Critic Asks a Question | In 1957, I published my novel The Naked Sun in book form. It was a science fiction mystery. Also, it had a rather understated love story in it with a rather toughing final scene between the lovers. Damon Knight reviewed the book, and he wasn't in the least impressed by the science fiction or the mystery. (I suppose he's entitled to his opinion, but I don't suppose it very hard.) However, he liked the love story. “If you can write like that, Asimov,” he asked rhetorically in the course of his review, “why do you bother writing science fiction?” To which I answered in a letter that appeared in the magazine in with the review had earlier appeared, “Because I love science fiction. No matter what else happens, I will never stop writing science fiction. …” (p. 25)

Extended excerpt  [Encyclopedia foreword, reprinted in Asimov essay collection]:

“It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be – and naturally this means that there must be an accurate perception of the world as it will be. This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.” (p. 19)

Extended excerpt  [Letter to children of Troy, MI, congratulating them on their new public library.]:

“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 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.”

Extended excerpt  [Non-fiction]:

“Knowledge is indivisible. When people grow wise in one direction, they are sure to make it easier for themselves to grow wise in other directions as well. On the other hand, when they split up knowledge, concentrate on their own field, and score and ignore other fields, they grow less wise – even in their own field.

How often people speak of art and science as though they were two entirely different things, with no interconnection. … That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true scientist is quite imaginative as well as rational, and sometimes leaps to solutions where reason can follow only slowly; if he does not, his science suffers. (p. 116)

“Old men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight. They become accustomed to the more plodding varieties of reason, and because this is more than made up by the accumulation of experience, old men think themselves wiser than the young.” (p. 131)

Extended excerpt [Interview]:

Interviewer Bill Moyers: “What's the real knowledge?”

Isaac Asimov: “We can't be absolutely certain. Science does not purvey absolute truth, science is a mechanism. It's a way of trying to improve your knowledge of nature, it's a system for testing your thoughts against the universe and seeing whether they match. This works not just for the ordinary aspects of science, but for all of life.” (p. 270)

Extended excerpt  [Essay]:

“It's hard to quarrel with that ancient justification of the free press: “America's right to know.” It seems almost cruel to ask, ingenuously, “America's right to know what, please? Science? Mathematics? Economics? Foreign languages?”

None of those things, of course. In fact, one might well suppose that the popular feeling is that Americans are a lot better off without any of that tripe.

There is a cult of ignorance in the United States, and there always has been. The strain of 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.” (column 1, p. 19)

Extended excerpt  [Essay]:

“In my recent book on the Bible, I naturally had occasion to refer to the plagues that visited Egypt in the time of Moses, as described in the Book of Exodus. In doing so I said:

“Although these plagues, if they had taken place as described in the Bible, must have loomed large in any contemporary records or in later histories, no reference to them is to be found in any source outside the Bible. In 1950, Immanuel Velikovsky, in his book Worlds in Collision attempted to account for the plagues (and for some other events described in the Bible) by supposing that the planet Venus had undergone a near collision with the earth. The book created a moderate sensation among the general public for a while but the reaction of astronomers varied from amusement to anger, and the Velikovsian theory has never, for one moment, been taken seriously either by scientists or by Biblical scholars.”

That's all I said, and it seems to me that I spoke gently and without undue heat. Nevertheless, the vials of wrath were opened upon me and I received a number of letters from ardent Velikovskians denouncing my innocent statement with a great deal of emotional fervor.

Which just goes to bear out my feeling that there is no belief, however foolish, that will not gather its faithful adherents who will defend it to the death.” (p. 36)

“There are many aspects of the universe that still cannot be explained satisfactorily by science; but ignorance implies only ignorance that may someday be conquered. To surrender to ignorance and call it God has always been premature, and it remains premature today.”  (Page 92, column 3 of NY Times Magazine. Page 378 of full electronic edition file.)

Re-quote note:

The phrase “last refuge of the incompetent” was not coined by Asimov. Although we did not find an earlier source that used the phrase to define violence, there were several other iterations of it in the early 1900s & late 1800s. Examples include:

1878: “Universal philanthropy is the last refuge of the incompetent.”

(Source: “Number One,” 7 March 1878, Truth magazine, Vol. III, London: Truth, p. 310)

1901: “The plea of the “inevitable” is the last refuge of the incompetent.”

(Source: Peace or War in South Africa, A.M.S. Methuen, London: Methuen & Co., 16th ed., p. 238)

1931: “Public office…is the last refuge of the incompetent.”

(Source: Boies Penrose, Pennsylvania senator, in “Power & Glory,” Collier's Weekly, 14 Feb. 1931)

Extended excerpt  [Fictional dialogue]:

“Yate Fulham's mustache twitched. “That sounds as if you have made up your mind that violence must be used against them.”

“Violence,” came the retort, “is the last refuge of the incompetent. But I certainly don't intent to lay down the welcome mat and brush off the best furniture for their use.”

   “I still don't like the way you put that,” insisted Fulham. “It is a dangerous attitude; the more dangerous because we have noticed lately that a sizable section of the populace seems to respond to all your suggestions just so.” (p. 49, column 2)

“After surveying new methods in aeronautical research, Mr. Wimperis said: “Can I truthfully say that all this activity is imperatively bound to add to human happiness? I fear not.

“The provision by scientific research of increased power over nature produces greater happiness if, and only if, it is wisely employed. The world gathers knowledge faster than wisdom.” (p. 9, column 5)

This quote is frequently misattributed to author Isaac Asimov. The words, however, are original to Alda – we could find no record of Asimov sharing this idea (or a similar phrase) in any of his writing, interviews or other material.

Extended excerpt  [Alan Alda's commencement speech to graduating class of Connecticut College. His daughter, Eve, was one of the students receiving her degree that day.]:

“If we can make distinctions, we can be tolerant, and we can get to the heart of our problems instead of wrestling endlessly with their gross exteriors. And once you make a habit of making distinctions, you'll begin challenging your own assumptions. Your assumptions are your windows on the world. Scrub them off every once in a while or the light won't come in. If you challenge your own, you won't be so quick to accept the unchallenged assumptions of others.” (pp. 2-3)
