Virus of the Mind: The New Science of the Meme

In Virus of the Mind, Richard Brodie carefully builds on the work of scientists Richard Dawkins, Douglas Hofstadter, Daniel Dennett, and others who have become fascinated with memes and their potential impact on our lives. But Richard goes beyond science and dives into the meat of the issue: is the emergence of this new science going to have an impact on our lives like the emergence of atomic physics did in the Cold War? He would say the impact will be at least as great. While atomic bombs affect everybody’s life, viruses of the mind touch lives in a more personal and more pernicious way.

Virus of the Mind is the first popular book devoted to the science of memetics, a controversial new field that transcends psychology, biology, anthropology, and cognitive science. Memetics is the science of memes, the invisible but very real DNA of human society.


Viruses of the mind are not a future worry: they are here with us now and are evolving to become better and better at their job of infecting us. The recent explosion of mass media and the information superhighway has made the earth a prime breeding ground for viruses of the mind.Mind viruses have already infected governments, educational systems, and inner cities, leading to some of the most pervasive and troublesome problems of society today: youth gangs, the welfare cycle, the deterioration of the public schools, and ever-growing government bureaucracy.

Will there be a mental plague? Will only some of us survive with our free will intact? Richard Brodie weaves together science, ethics, and current events as he raises these and other very disturbing questions about memes.

The Fabric of the Cosmos: Space, Time, and the Texture of Reality

String theory is a recent development in physics that, by positing that all which exists is composed of infinitesimally small vibrating loops of energy, seeks to unify Einstein's theories and those of quantum mechanics into a so-called "theory of everything." In 1999, Greene, one of the world's leading physicists, published The Elegant Universe (Norton), a popular presentation of string theory that became a major bestseller and, last fall, a highly rated PBS/Nova series. The strength of the book resided in Greene's unparalleled (among contemporary science writers) ability to translate higher mathematics (the language of physics) and its findings into everyday language and images, through adept use of metaphor and analogy, and crisp, witty prose. The same virtues adhere to this new book, which offers a lively view of human understanding of space and time, an understanding of which string theory is an as-yet unproven advance. To do this, Greene takes a roughly chronological approach, beginning with Newton, moving through Einstein and quantum physics, and on to string theory and its hypotheses (that there are 11 dimensions, ten of space and one of time; that there may be an abundance of parallel universes; that time travel may be possible, and so on) and imminent experiments that may test some of its tenets. None of this is easy reading, mostly because the concepts are tough to grasp and Greene never seems to compromise on accuracy. Eighty-five line drawings ease the task, however, as does Greene's felicitous narration; most importantly, though, Greene not only makes concepts clear but explains why they matter. He opens the book with a discussion of Camus's The Myth of Sisyphus, setting a humanistic tone that he sustains throughout. This is popular science writing of the highest order, with copious endnotes that, unlike the text, include some math.

How the Mind Works

MIT's Pinker, who received considerable acclaim for The Language Instinct (LJ 2/1/94), turns his attention to how the mind functions and how and why it evolved as it did. The author relies primarily on the computational theory of mind and the theory of the natural selection of replicators to explain how the mind perceives, reasons, interacts socially, experiences varied emotions, creates, and philosophizes. Drawing upon theory and research from a variety of disciplines (most notably cognitive science and evolutionary biology) and using the principle of "reverse-engineering," Pinker speculates on what the mind was designed to do and how it has evolved into a system of "psychological faculties or mental modules." His latest book is extraordinarily ambitious, often complex, occasionally tedious, frequently entertaining, and consistently challenging.

Why do fools fall in love? Why does a man's annual salary, on average, increase $600 with each inch of his height? When a crack dealer guns down a rival, how is he just like Alexander Hamilton, whose face is on the ten-dollar bill? How do optical illusions function as windows on the human soul? Cheerful, cheeky, occasionally outrageous MIT psychologist Steven Pinker answers all of the above and more in his marvelously fun, awesomely informative survey of modern brain science. Pinker argues that Darwin plus canny computer programs are the key to understanding ourselves--but he also throws in apt references to Star Trek, Star Wars, The Far Side, history, literature, W. C. Fields, Mozart, Marilyn Monroe, surrealism, experimental psychology, and Moulay Ismail the Bloodthirsty and his 888 children. If How the Mind Works were a rock show, tickets would be scalped for $100. This book deserved its spot as Number One on bestseller lists. It belongs on a short shelf alongside such classics as Darwin's Dangerous Idea: Evolution and the Meanings of Life, by Daniel C. Dennett, and The Moral Animal: Why We Are the Way We Are: The New Science of Evolutionary Psychology, by Robert Wright. Pinker's startling ideas pop out as dramatically as those hidden pictures in a Magic Eye 3D stereogram poster, which he also explains in brilliantly lucid prose.

The Art of Changing the Brain: Enriching the Practice of Teaching by Exploring the Biology of Learning

Neuroscience tells us that the products of the mind--thought, emotions, artistic creation--are the result of the interactions of the biological brain with our senses and the physical world: in short, that thinking and learning are the products of a biological process.

This realization, that learning actually alters the brain by changing the number and strength of synapses, offers a powerful foundation for rethinking teaching practice and one's philosophy of teaching.

James Zull invites teachers in higher education or any other setting to accompany him in his exploration of what scientists can tell us about the brain and to discover how this knowledge can influence the practice of teaching. He describes the brain in clear non-technical language and an engaging conversational tone, highlighting its functions and parts and how they interact, and always relating them to the real world of the classroom and his own evolution as a teacher.

"The Art of Changing the Brain" is grounded in the practicalities and challenges of creating effective opportunities for deep and lasting learning, and of dealing with students as unique learners.

The Selfish Gene: 30th Anniversary Edition

Inheriting the mantle of revolutionary biologist from Darwin, Watson, and Crick, Richard Dawkins forced an enormous change in the way we see ourselves and the world with the publication of The Selfish Gene. Suppose, instead of thinking about organisms using genes to reproduce themselves, as we had since Mendel's work was rediscovered, we turn it around and imagine that "our" genes build and maintain us in order to make more genes. That simple reversal seems to answer many puzzlers which had stumped scientists for years, and we haven't thought of evolution in the same way since.

Why are there miles and miles of "unused" DNA within each of our bodies? Why should a bee give up its own chance to reproduce to help raise her sisters and brothers? With a prophet's clarity, Dawkins told us the answers from the perspective of molecules competing for limited space and resources to produce more of their own kind. Drawing fascinating examples from every field of biology, he paved the way for a serious re-evaluation of evolution. He also introduced the concept of self-reproducing ideas, or memes, which (seemingly) use humans exclusively for their propagation. If we are puppets, he says, at least we can try to understand our strings. --Rob Lightner --This text refers to an out of print or unavailable edition of this title.

The Greatest Show on Earth -The Evidence for Evolution

The Greatest Show on Earth with a short history of his writing career. He explains that all of his previous books have naïvely assumed the fact of evolution, which meant that he never got around to laying out the evidence that it [evolution] is true. This shouldn't be too surprising: science is an edifice of tested assumptions, and just as physicists must assume the truth of gravity before moving on to quantum mechanics, so do biologists depend on the reality of evolution. It's the theory that makes every other theory possible.Yet Dawkins also came to realize that a disturbingly large percentage of the American and British public didn't share his enthusiasm for evolution. In fact, they actively abhorred the idea, since it seemed to contradict the Bible and diminish the role of God. So Dawkins decided to write a book for these history-deniers, in which he would dispassionately demonstrate the truth of evolution beyond sane, informed, intelligent doubt.After only a few pages of The Greatest Show on Earth, however, it becomes clear that Dawkins doesn't do dispassionate, and that he's not particularly interested in convincing believers to believe in evolution. He repeatedly compares creationists and Holocaust deniers, which is a peculiar way of reaching out to the other side. Elsewhere, Dawkins calls those who don't subscribe to evolution ignorant, fatuously ignorant and ridiculous. All of which raises the point: who, exactly, is supposed to read this book? Is Dawkins preaching to the choir or trying to convert the uninformed? While The Greatest Show on Earthmight fail as a work of persuasive rhetoric—Dawkins is too angry and acerbic to convince his opponents—it succeeds as an encyclopedic summary of evolutionary biology. If Charles Darwin walked into a 21st-century bookstore and wanted to know how his theory had fared, this is the book he should pick up.Dawkins remains a superb translator of complex scientific concepts. It doesn't matter if he's spinning metaphors for the fossil record (like a spy camera in a murder trial) or deftly explaining the method by which scientists measure the genetic difference between distinct species: he has a way of making the drollest details feel like a revelation. Even if one already believes in the survival of the fittest, there is something thrilling about learning that the hoof of a horse is homologous to the fingernail of the human middle finger, or that some dinosaurs had a second brain of ganglion cells in their pelvis, which helped compensate for the tiny brain in their head. As Darwin famously noted, There is grandeur in this view of life. What Dawkins demonstrates is that this view of life isn't just grand: it's also undeniably true. Color illus.
