Surfaces and Essences: Analogy as the Fuel and Fire of Thinking by Douglas R Hofstadter (PDF)

Description

Analogy is the core of all thinking. This is the simple but unorthodox premise that Pulitzer Prize — winning author Douglas Hofstadter and French psychologist Emmanuel Sander defend in their new work. Hofstadter has been grappling with the mysteries of human thought for over thirty years. Now, with his trademark wit and special talent for making complex ideas vivid, he has partnered with Sander to put forth a highly novel perspective on cognition. We are constantly faced with a swirling and intermingling multitude of ill-defined situations. Our brain’s job is to try to make sense of this unpredictable, swarming chaos of stimuli. How does it do so? The ceaseless hail of input triggers analogies galore, helping us to pinpoint the essence of what is going on. Often this means the spontaneous evocation of words, sometimes idioms, sometimes the triggering of nameless, long-buried memories. Why did two-year-old Camille proudly exclaim, “I undressed the banana!”? Why do people who hear a story often blurt out, “Exactly the same thing happened to me!” when it was a completely different event? How do we recognize an aggressive driver from a split-second glance in our rearview mirror? What in a friend’s remark triggers the offhand reply, “That’s just sour grapes”? What did Albert Einstein see that made him suspect that light consists of particles when a century of research had driven the final nail in the coffin of that long-dead idea? The answer to all these questions, of course, is analogy-making — the meat and potatoes, the heart and soul, the fuel and fire, the gist and the crux, the lifeblood and the wellsprings of thought. Analogy-making, far from happening at rare intervals, occurs at all moments, defining thinking from top to toe, from the tiniest and most fleeting thoughts to the most creative scientific insights. Like Gö, Escher, Bach before it, Surfaces and Essences will profoundly enrich our understanding of our own minds. By plunging the reader into an extraordinary variety of colorful situations involving language, thought, and memory, by revealing bit by bit the constantly churning cognitive mechanisms normally completely hidden from view, and by discovering in them one central, invariant core — the incessant, unconscious quest for strong analogical links to past experiences — this book puts forth a radical and deeply surprising new vision of the act of thinking.

User’s Reviews

Editorial Reviews: From Booklist *Starred Review* In what Einstein cherished as the “happiest thought” of his life, Hofstadter and Sander discern a mental process that empowers the mind not just of the rare genius but also of the ordinary person. That process—the framing of analogies—received favorable attention from Plato and Aristotle, Kant and Nietzsche. But many modern empiricists, including Hobbes and Locke, have warned against analogies as intellectual snares. And many tunnel-visioned students see in analogical thinking only the logic-chopping of an IQ test. Hofstadter and Sander tear through the misperceptions, demonstrating the astonishing conceptual power of analogies—manifest when mathematicians venture from real to imaginary numbers, when physicists leap from photons to vector bosons. That power shows up in unexpectedly ubiquitous, ordinary ways, though, as we meet everyday challenges by categorizing the features of those challenges and by dredging up forgotten but relevant past experiences to interpret them. Surprisingly, only analogies enable us to recognize deep essences behind surface appearances and to weigh competing options in national policy or personal life. Readers do confront the risks of false and stereotypical analogies, but soon realize that analogy-making is the pilot light of creativity—and essential for adapting to a changing world. A revelatory foray into the dynamics of the mind. –Bryce Christensen Review Kirkus Reviews, starred review“How do we know what we know? How do we know at all? With an enjoyable blend of hard science and good storytelling, Hofstadter and French psychologist Sander tackle these most elusive of philosophical matters…. [I]t’s worth sticking with [Hofstadter’s] long argument, full of up-to-date cognitive science and, at the end, a beguiling look at how the theory of relativity owes to analogy…. First rate popular science: difficult but rewarding.”Melanie Mitchell, Professor of Computer Science, Portland State University, and author of Complexity: A Guided Tour“Hofstadter and Sander’s book is a wonderful and insightful account of the role of analogy in cognition. Immensely enjoyable, with a plethora of fascinating examples and anecdotes, this book will make you understand your own thought processes in a wholly new way. It’s analogy all the way down!”Steven Pinker, Harvard College Professor of Psychology, Harvard University, and author of How the Mind Works and The Stuff of Thought“I am one of those cognitive scientists who believe that analogy is a key to explaining human intelligence. This magnum opus by Douglas Hofstadter, who has reflected on the nature of analogy for decades, and Emmanuel Sander, is a milestone in our understanding of human thought, filled with insights and new ideas.”Gerald Holton, Professor of Physics and History of Science, Emeritus, Harvard University“Hofstadter and Sander’s book starts with two audacious goals: to show that none of us can think a minute without using a variety of analogies, and that becoming aware of this fact can help us think more clearly. Then, patiently and with humor, the authors prove their claims across the whole spectrum, from everyday conversation to scientific thought processes, even that of Einstein.”Nancy J. Nersessian, Professor of Cognitive Science, Georgia Institute of Technology, and author of Creating Scientific Concepts“Placing analogy at the core of cognition Hofstadter and Sander provide a persuasive answer to the question ‘what is thought?’ Analogy is the mechanism underlying the myriad instances of concept formation and categorization we perform throughout any day, whether unconscious or explicit, without which there would be no thought. They mount a compelling case through analysis of a wealth of insightful—imaginative and real—exemplars, from everyday thinking to the highest achievements of the human mind, which are sure to persuade a broad range of readers.”Longlisted for the 2014 PEN / E. O. Wilson Literary Science Writing AwardScience“Surfaces and Essences warrants a place alongside Gödel, Escher, Bach and major recent treatments of human cognition. Analogy is not the endpoint of understanding, but its indispensable beginning.”Nature“Lucid and, page for page, a delight to read…. [Surfaces and Essences contains] gems of insight.”Wall Street Journal”Clear, lively, and personal.”Globe and Mail (Canada)“Knowing what makes a duck a bird and what makes a plane not a bird may not seem like very profound mental feats—but Douglas Hofstadter and Emmanuel Sander see such cognitive connections as part of an extraordinarily profound process…. Be prepared to become hyper-conscious of the myriad of analogies one makes every moment of every day…. The end result is a book that is ambitious and provocative.”Booklist, starred review“A revelatory foray into the dynamics of the mind.”Library Journal“Like Hofstadter’s Pulitzer Prize-winning Godel, Escher, Bach, this work executes, from a very complex thesis, an understanding by general readers while also appealing to specialists in philosophy of mind and cognitive science.” About the Author Douglas Hofstadter is Distinguished College of Arts and Sciences Professor of Cognitive Science and Comparative Literature at Indiana University. His previous books include Gö, Escher, Bach (which won the Pulitzer Prize for General Nonfiction in 1980) and Fluid Concepts and Creative Analogies. Emmanuel Sander is Professor of Cognitive and Developmental Psychology at the University of Paris (Saint-Denis), specializing in the study of analogy-making and categorization and their connections to education. Among his previous works is the book Analogy, from the Naï to the Creative. Read more

⭐How does your mind work? Would you be a better thinker if you knew? Let’s do a simple thought experiment. Suppose you were in a new building in front of a door with its knob. Now follow your mind in slow motion. From hundreds of door knobs that you have found previously in your life, you have somehow extracted the essence of “door knobs”: you know more or less how they look and how they work. The surface characteristics of this new door knob may be different from all others previously found; however your mind instantly and unconsciously makes an analogy – a mental bridge – between the new one and others stored in your memory; instantly and equally unconsciously, assigns this new object to the category “door knobs”. The essence is then somehow retrieved, and you just rotate the thing to open the door…Surfaces and essences, analogies and categories are what this book is all about. They are the essential mechanisms of thought, intelligence, creativity, learning and expertise… all that! It is a book on Cognitive Science, but written in a witty engaging delightful way.The main thesis of the book can be stated in a single paragraph: making analogies and constructing categories of things in our mind are just two views of the same mechanism that pervades and forms the basis of human thought. From run-of-the-mill thinking activities such as choosing what word to say next to the highest reaches of expertise and creativity, the mind unconsciously brings in analogies and categories; further, both come with blurry boundaries and in increasing levels of abstraction.The authors defend their thesis mainly by presenting a delicious bouquet of analogies and categories as examples. To explain these examples, they also use analogies and metaphors galore, including analogies about analogies, resulting in a delightfully recursive book.First, Hofstadter & Sanders clear the way by explaining that an analogy is not just a rhetorical device, but that we use it all the time or, more strongly, we think through analogies. It is simply recognizing a stimulus that comes to us and comparing it (making an analogy) with previous similar stimulus stored in our memory, just as we saw with the example of the door knob. The stimulus may come through our senses or our imagination.For a contrasting example, the last chapter is dedicated in part to the extraordinarily creative analogies made by Albert Einstein, that enabled him to make his astonishing discoveries. Furthermore, the authors make clear that this analogical thought came to Einstein’s mind before his formidable mathematical formalizations.Between these extreme examples, the book presents a gamut of frequent situations that provoke our mind to use analogies and categories starting with single words! For example, a word-concept such as “dog” is a category that denotes thousands of these four-legged animals. But the surprise here is that non-noun words such as verbs (“to open” can be used to open doors, corpses, books, online folders…), and adverbs such as “much” and others also bring to mind categories and analogies. Phrases like “that’s much too little for him and too much for me”; “how much will that be?”; “much obliged” spring to mind when we recognize the category of a “much situation”. That’s a mental comparison between one situation and another, and of course that mental comparison is an analogy: a bridge between two mental structures.Single words that initially denote a single entity, such as the “moon”, mutate over time to become categories. Galileo spoke of “the moons of jupiter”. We now speak of the moons of other planets in or out of our galaxy.Some trademarks equally evolve to become categories, such as Kleenex and Googling.The boundaries of categories are always blurry and continuously expand during the development of a child. Initially “mommy” is a single person, but later the kid learns that “Fido is the mother of this puppy”, “The queen bee is the mother of the bee-hive”, and even of “Mother Nature” as the mother of all things alive… Children routinely use creative analogies: “I undressed the banana”, says a little girl; “Mommy, the rain has been turned off!” and so on. Adults too constantly expand categories: The legs of a table; the spine of a book; a head of lettuce… let us go and have a coffee even if one person may order tea. All categories are then used when making an analogy between a new stimulus and members of the category.The authors also consider compound words (dog dish), idioms that also denote a multitude of situations (To roll one’s sleeves up) as well as proverbs (The early bird catches the worm), and fables (“The Fox and the Grapes” by Aesop reduced to the category sour grapes, denoting things that one once craved deeply but failed to obtain and then disparages).There are many examples of “invisible analogies” (or categories…) that we construct and use spontaneously, such as “items to save if ones’ house burns down”, “items to pack for a picnic” and so on; and we have no trouble imagining for instance “activities typical of camping trip”s or “people whom one might have married”.Next, consider the ubiquitous “me too” situations: someone describes something that happened to him of her and we interrupt and say “A similar thing happened to me…” and on it goes our description of an analogous situation. How do we encode these experiences in memory so that later on we instantly recognize some essence of the experience and launch into explaining a similar one? Do we store that essence initially and subsequently enrich it; or the essence is actually built in real time when needed? It is a great mystery, since the same anecdote can be used as a “me too” in different contexts.The same item may belong to thousands of categories depending on context or point of view. The authors make this as clear as clear water (an analogy…) by presenting the story of “a drinking glass”: it is born as a product, and goes on to become an item for sale, a discounted item, a sold item, a water-container, an insect-holder, occasionally a wine-holder, a broken item, a recyclable object and dozens other categories… Our mind easily and transparently re-assigns categories; extends the boundaries of categories (“desk” has evolved to become also virtual desk; a “wave” once upon a time could only be found in liquids and now we have electromagnetic and even gravitational waves); and makes increasingly abstract categories, such as going from a particular four-legged entity that barks next door to the categories bulldog, dog, mammal, animal, live-being and so on.Analogies firmly entrenched into memory also act as filters of reality, distorting it. They come to mind uninvited, spontaneously, and sometimes manipulate our mind without us realizing it. Some of them are quite innocent, such as inevitably thinking of September 11 when hearing the news about the small plane crashing against a building on October 11, 2006. There are other more serious, when an analogy comes to mind that misleads us or takes us in the wrong direction. Take for instance calling one’s life partner with the name of one’s lover because of some hidden similarity… Actually, people are more convinced by their previous concepts, analogies and categories than from barrages of scientific facts, such as can be seen by the recent diatribes against climate science or the theory of evolution.We are thus “prisoners of the known”, yet “only the known can free us from the unknown”, and can therefore also be conscious of, extend, change and invent analogies. Sometimes we spontaneously create metaphors just for fun or to make a point or to explain something to ourselves or others. The authors call these “caricature analogies”. But analogies are also made for more serious purposes – for instance when going to a job interview, we inevitably make analogies to previous work interviews and our experiences in them; or when going out with a new date, our experiences with previous persons may color our perception. And analogies are the bread and butter of sophisticated human translators, who are thoroughly familiar with the concepts, idioms, turns of phrase and analogies usually used in two cultures.An analogy may start its life as a naive analogy. A certain pain may be assigned to the category stomach ache, which is not wrong but too general for accurate diagnosis. Hofstadter and Sanders show that the arithmetic operation of division usually associated at school with the concept of sharing (say ten marbles to be shared among five kids and many other instances of the category…) gets children into trouble when the result of the division is greater than the quotient, as it happens when dividing by a number smaller than one. Division as sharing thus is an example of a naive category that does not help, but rather hinders further comprehension; the kids then need to acquire another way of looking at the category, Division as using the dividend to measure the divisor.So as that example shows, are analogies also at the root of the most formal of sciences, e.g. Mathematics? Indeed they are! The authors show that analogies are also at the origin of more complex math concepts such as groups, rings, fields… These are other examples showing that sometimes we are the bosses, and analogies the slaves of our creativity.The authors also reflect on the nature of intelligence, expertise, learning and creativity. They say that the essence of intelligence is the ability to instantly find precise, interesting, creative analogies. This is what makes “homo sapiens, sapiens”. Analogies help us understand our own experiences and others’.An expert is “simply” a person that has a vast store of carefully organized and detailed categories at multiple levels of abstraction. Making an analogy to previous situations encountered enables the expert to pinpoint problems and find solutions to them.Creativity is often stated as synonymous to “thinking out of the box”, which is a useless advice if one doesn’t know the limits of one’s boxes. An example presented in the book is the creative act of pushing a wine bottle’s cork in rather than taking it out when there is no corkscrew on sight. This depends on abstracting the category “ways of taking a cork out” to “ways of accessing the wine”.Hofstadter & Sanders criticize school systems and curricula for not taking seriously the role of analogy in learning. Children learn through making analogies to previous mental structures built in and out of school. Nothing can be learnt in abstract form independently of everything else. Initial naive analogies persist in memory even after mathematical formalizations have been taught.The last chapter is dedicated to creative analogies that have been used in math and physics. Particularly fascinating is a trip through Einstein’s mind, showing the incredible ability that the famous scientist had for pinpointing the right analogy from which he then derived his world-famous discoveries. Even more than a math and physics genius, he was an analogizer extraordinaire, in the words of the authors.You’ll have great fun with Hofstadter & Sanders’ writing style as they defend their thesis that analogies and categories, surfaces and essences are at the root of the way our mind works. Enjoy the examples of everyday and scientific situations as you watch the workings of your mind in slow-motion. This experience will make you a better thinker!

⭐I attended a semester-long seminar by the author, Douglas Hofstadter (who was my Ph.D. advisor), titled something like “What is Thinking?” or maybe “What is Thought”? while he was busy working on this book. Much of the content of that seminar ended up in the book, and of course it’s extremely clear and well-written, and a much better reference for me than the hastily-scribbled and excited notes I took every day in that seminar.The topic of the seminar and book is asking the question “What is cognition?” and “how does thinking work?” along with Hofstadter’s thesis that “Analogy is the core of cognition”. I had read this idea from Hofstadter and his students before, but didn’t give it too much serious thought, until participating in the seminar, and becoming convinced that this is just as critical as Hofstadter claims.After the seminar, I had the immense privilege of moving to Paris, France for a semester, so that I could continue meeting with Hofstadter periodically while I worked on my Ph.D. research. He was spending the semester there to collaborate on the book with his French co-author, Emmanuel Sander. I mention this because this collaboration adds an extra flavor to the book that makes it slightly different than his other books, and also because it’s not the kind of collaboration where one person writes half the book and the other writes the other half. Instead, this was a much closer partnership involving each chapter of the book. It also means that the book involves some fun examples from France that might have been missing otherwise, so for a francophile it’s an added bonus — the truly dedicated reader can also pick up a copy in French, because the two coauthors worked on both versions in parallel (they are both fluent in both English and French).I don’t have time for a more detailed review, but I can’t recommend this highly enough, especially for people involved in AI or cognitive science. Especially in an age where massive deep learning AI models are all the rage, this book is a great reminder of the things that really matter in human cognition.

⭐I wish I could say I was a big fan of Hofstadter. His

⭐Godel, Escher, Bach: An Eternal Golden Braid

⭐was one of the first real books I read and put me on the path of philosophy and computer science, his work with Dennet has been a guide throughout my study years, and his

⭐Le Ton Beau De Marot

⭐is one of the best books on translation that I know of. However, this latest tome (which at almost six hundred pages one is justified in calling it) does not live up to the standard that Hofstadter has set for himself.The premise of this book is that analogy (metaphors) are at the core of all thinking. As is usual with Hofstadter’s work, this premise is tested and demonstrated using linguistics and introspection. Giving examples of the way people communicate, and thereby often misinterpret one another, Hofstadter and Sander show that most if not all language-usage depend on the mutual understanding of analogies. Those analogies in itself are fluid, so that concept-building is an organic process which is in itself influenced by analogy.Though interesting in itself, the book could have been at least half its size shorter, had not the authors decided to come up with example after example of the point they are trying to make at a specific place. On nearly every page we see examples of situations that are, in the end, not all the difficult to understand or recognise. And those examples are in themselves more often than not described with too much (unnecessary) detail.In fact, the book they should have come up with would be not that much different from Lakoff and Johnson’s

⭐Metaphors We Live By

⭐(1980). Given the fact that on page 63 they actually refer to this work, it is obvious that they know about it. It is at least strange that Hofstadter and Sander do not give more credit where credit is due.

⭐Arrived earlier than expected. Great condition too. I love his easy to read style. Bought for MA dissertation research.

⭐500 Seiten über ein Thema in dessen Kern es um Reduktion geht? Hat sich da Douglas Hofstadter, der Meister der Metabeziehung, etwa einen Scherz erlaubt?Einem Menschen die Rolle der Analogie in seinem Denken bewusst zu machen ist wie einem Fisch etwas über Wasser erzählen zu wollen, die Schwierigkeit dabei liegt in der Selbstverständlichkeit. Wie bringt man ihm also das Thema Analogien näher? Natürlich durch Analogien!So erklären sich auch die 500 Seiten, denn Analogien zu den Facetten der Analogie gibt es reichlich, vorwiegend durch Beispiele aus den Bereichen Alltag, Sprache, Bildung und auch Naturwissenschaft. Die Brücke ins professionelle Engineering und Business schlagen die Autoren wohl bewusst nicht. Jedes Beispiel für sich genommen ist ein gut aufgebautes originelles Lesevergnügen, welches die jeweiligen Aspekte des Themas Analogie treffsicher veranschaulicht. Das Buch zielt dabei nicht auf eine wissenschaftlich strenge Behandlung, sondern auf das Verständnis für Jedermann.Man muss das Buch nicht von Vorne nach Hinten Lesen, sollte man auch nicht, denn die beleuchteten Aspekte werden häufig episch breit ausgewalzt. Kürzere oder speziellere Lesepfade werden leider nicht angeboten (z.B. Prolog + Kapitel 4). Das Problem des Werkes ist somit nicht die 500 seitige Masse, sondern die mangelnde Struktur. Wie wir aber in Kapitel 4 lernen, ist es jedoch gerade die Fähigkeit zur Strukturierung seines Fachgebietes die den Experten ausmacht. Da ist den Autoren dann also doch ein Metascherz gelungen – oder wohl eher unterlaufen – der die Freude beim Lesen leider merklich dämpft.

⭐

⭐Almost 600 pages to show at great length the use of analogies in the human brain. Hofstadter and Sander have written a book with two complete versions, one in English and one in French. The two languages enrich each other for the thesis of this book. Hofstadter and Sander present a very thorough case with lots of amazing examples of analogies, at different levels of understanding. We are taken through that effortlessly. We can thus spot when and where writers, presenters use analogies and to what purpose (pervasively). The link to irony and humor is not developed. It could have been an interesting avenue. Finally, the authors make it as if only analogies are the engines of the mind. I think that model-building which makes us anticipate our every action is at least one possible complement to that very convincing theory. Entertaining throughout. An example, page 95, we get a whole list of idioms: just amazing.

⭐To use an analogy, the writing style of this book is a guitarist in tight leather trousers, one foot on an amp, crotch thrusted at the audience, performing a five minute solo….Why use one example when you can use fifty? Why use three short flowing sentences when you can weave it all into one and demonstrate your command of the word “notwithstanding”?Even the pages are too wide to find the line that you were reading when you read down…The only thing that would be worse is if the book played the background music of a small crying child when you opened it.
