Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being [Paperback]

George Lakoff (Author), Rafael Nuñez (Author)

Book Description

Publication Date: August 7, 2001

This book is about mathematical ideas, about what mathematics means-and why. Abstract ideas, for the most part, arise via conceptual metaphor-metaphorical ideas projecting from the way we function in the everyday physical world. Where Mathematics Comes From argues that conceptual metaphor plays a central role in mathematical ideas within the cognitive unconscious-from arithmetic and algebra to sets and logic to infinity in all of its forms.

If Barbie thinks math class is tough, what could she possibly think about math as a class of metaphorical thought? Cognitive scientists George Lakoff and Rafael Nuñez explore that theme in great depth in Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being. This book is not for the faint of heart or those with an aversion to heavy abstraction--Lakoff and Nuñez pull no punches in their analysis of mathematical thinking. Their basic premise, that all of mathematics is derived from the metaphors we use to maneuver in the world around us, is easy enough to grasp, but following the reasoning requires a willingness to approach complex mathematical and linguistic concepts--a combination that is sure to alienate a fair number of readers.

Those willing to brave its rigors will find Where Mathematics Comes From rewarding and profoundly thought-provoking. The heart of the book wrestles with the important concept of infinity and tries to explain how our limited experience in a seemingly finite world can lead to such a crazy idea. The authors know their math and their cognitive theory. While those who want their abstractions to reflect the real world rather than merely the insides of their skulls will have trouble reading while rolling their eyes, most readers will take to the new conception of mathematical thinking as a satisfying, if challenging, solution. --Rob Lightner

From Publishers Weekly

This groundbreaking exploration by linguist Lakoff (co-author, with Mark Johnson, of Metaphors We Live By) and psychologist N#$ez (co-editor of Reclaiming Cognition) brings two decades of insights from cognitive science to bear on the nature of human mathematical thought, beginning with the basic, pre-verbal ability to do simple arithmetic on quantities of four or less, and encompassing set theory, multiple forms of infinity and the demystification of more enigmatic mathematical truths. Their purpose is to begin laying the foundations for a truly scientific understanding of human mathematical thought, grounded in processes common to all human cognition. They find that four distinct but related processes metaphorically structure basic arithmetic: object collection, object construction, using a measuring stick and moving along a path. By carefully unfolding these primitive examples and then building upon them, the authors take readers on a dazzling excursion without sacrificing the rigor of their exposition. Lakoff and N#$ez directly challenge the most cherished myths about the nature of mathematical truth, offering instead a fresh, profound, empirically grounded insight into the meaning of mathematical ideas. This revolutionary account is bound to garner major attention in the scientific pressDbut it remains a very challenging read that lends itself mostly to those with a strong interest in either math or cognitive science.

4.0 out of 5 stars Traces back all math to simplest observations. Long read., November 8, 2002

This review is from: Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being (Paperback)

Whenever a person finds out that I'm a math enthusiast, 9 times out of 10 I get an uncomfortable reaction along the lines of "Oh, I HATE math!" In my experience, the mathphobe's biggest gripe is that math is a completely abstract concept, all based on memorization of some strange language, with so much of it having absolutely no comparison to the physical world.

This book strives to show that mathematics, from basic arithmetic to more advanced branches, can in fact all be reduced down to mental metaphors of physical concepts. Early in the book, the authors present the sound scientific evidence that humans have an innate understanding of the concept of quantity, and some degree of manipluation with quantity. This ultimately leads to an understanding of addition, and then subtraction. Those concepts, combined with the understanding of how to group objects in like sets, leads to an understanding of multiplication (add like sets) and division (subtract like sets). The book then introduces a few more fundamental ideas that the human brain can use to make analogies with (motion along a path, rotation, etc.), and recreates more common mathematical concepts in increasing complexity: geometry, trigonometry, logic, set theory, etc. At the end the book the authors even successfullly tackles Euler's equation (e^i*pi = -1), a classic example of something in mathematics that doesn't make any logical sense at first glance.

The book is extremely thorough in the way it presents all this. Most chapters start off by introducing a new cognative metaphor, then including a table showing the mathematical concepts to be presented and to which cognative metaphor each one relates. For a book on mathematics, this is actually a rather long read. It's thorough because it has to be, given the subject and the authors' claims. But the book might seem to drag around the middle, with a lot of repitition in each chapter as the strategy in breaking down the mathematics is constantly applied.

Still, I found this to be an overall very interesting read. I think the authors succeed in showing how all sorts of math concepts break down to the simplest fundamentals, which in turn can be mentally assocated with concepts we can understand in the real world.

5.0 out of 5 stars I have seen the future of math and hope it works..., June 24, 2005

This review is from: Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being (Hardcover)

I give this book 5 stars not because it is definitive and "correct," but because it proposes an exciting new tack in the philosophy of mathematics. This deeply fascinating book would have been a major addition to that philosophy, a most noble subject, were it not that the authors know little about it. For starters, they do not appreciate the extent to which intuitionists and constructivists have anticipated their attack on what they rightly deprecate as the Romance of (Platonic) Mathematics. Intuitionists entirely agree that mathematics is a human construction serving human purposes; mathematics has no existence apart from this fact.

The philosophy of math has attracted some fine and exciting minds since Frege published his Begriffschrifft in 1879. Around 1900: Russell, of course, but also Husserl. Around 1940: Godel, Quine, Fraenkel, Bernays, Church, Curry, Brouwer, Weyl. More recently: Chihara, Boolos, Parsons, Resnick, Maddy, Shapiro, Detlefsen, Hartrey Field, Burgess, Rosen, Putnam. Regrettably, Lakoff and Nunez appear to have assimilated almost none of this literature.

This cognitive business will eventually have to interact with logic and Ed Zalta's formal theory of abstract objects.

Mathematicians reviewing this book in professional journals, as well as a number of Amazon reviewers, have complained of serious failings in L&N's understanding of some mathematical points. Lakoff argues that the errors found in earlier printings of WMCF are now corrected. On verra...

Readers should keep in mind that Lakoff is a linguist who made his reputation by linking linguistics to cognitive science and the analysis of metaphor. Nunez is a product of the Swiss school of mathematics as grist for cognitive psychology, founded by Piaget. Neither is well-trained in logic, the philosophy of set theory, the axiomatic method, metamathematics, nonstandard analysis and the ontological presuppositions of calculus, the derivations of number systems, and so on.

This book builds on two earlier fine books by Lakoff, his (1987) "Women, Fire and Dangerous Things" and his (1999 with Mark Johnson) "Philosophy in the Flesh.". Both books are very far from academic writing at its worst, but their probing analyses of metaphor, Image Schemata, and other concepts from second-generation cognitive science are not easy. Lakoff (1987) was fascinated by some technical ideas of Putnam's, about which WMCF is unaccountably silent. Lakoff and Johnson contains philosophical riches (thanks to Johnson, a significant contemporary philosopher) that I miss in WMCF. Lakoff and Nunez rightly invoke the authority of Saunders MacLane in support of their position. The authors acknowledge Reuben Hersh very warmly, but do not seem acquainted with his (with Philip Davis) "The Mathematical Experience." WMCF does not cite J R Lucas's "The Conceptual Roots of Mathematics" at all.

Nunez has devoted much of his career to thinking about the foundations of analysis, the real and complex numbers, and about what he calls the Basic Metaphor of Infinity. These topics, worthy though they be, form part of the superstructure of mathematics. The efforts of cognitive science should, I submit, be redirected to the foundations thereof. Now Lakoff and Nunez do pay a fair bit of attention early on to logic, Boolean algebra, and the Zermelo-Fraenkel axioms. And they do linger a bit over group theory. But logic, set theory, number systems, algebra, relations, mereology, topology, and geometry, more or less in that order, should have been the primary focus of their investigation.

I sense that many working mathematicians resist the approach and conclusions of Lakoff and Nunez. This situation is to be regretted. Mathematics has become an extremely powerful toolbox for the mind. Logic and abstract algebra have much to offer to the social sciences and humanities. But communicating these riches to the wider community has proved difficult, and the problem is worsening. For instance, it seems that set theory has vanished from the school curriculum. My students tell me they do not even hear the word "set" spoken until their second year at university. (I learned the core of intuitive set theory around age 12 in the 1960s, and the power of set theoretic metaphors has delighted me ever since.) Even something as basic as first order logic is nowadays learned only by the more technical philosophy majors, and by a small subset of math majors. Hence only a few specialists learn more than calculus, applied statistics, differential equations, and a bit of linear algebra. Just how many persons with a university education know what an equivalence class is? A partial order? A morphism? What it means for a set of axioms to have a model? It is my hope that the cognitive approach to mathematics will suggest improvements to the toolbox of abstractions, and better ways to communicate that toolbox to nonspecialists.

5.0 out of 5 stars Refreshing approach to the ideas of mathematics, November 30, 2000

By 

David W. Craig - See all my reviews

This review is from: Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being (Hardcover)

As a physicist and recreational mathematician, I found this book stimulating and reassuring. The connection of mathematics to human realities in our embodied world gives a new way to understand the conceptual and practical power of mathematics, as well as approach its limitations. I also found it helps to explain my preference for "seat of the pants" approach to some subjects, as contrasted to the proof-driven esthetic of many professional mathematicians. I think this book may encourage new ideas in mathematics education as well. If you're a Platonist, you'll find a lot to scream about, but its a great read for any math nut.
