This exciting, timely book combines cutting-edge findings in neuroscience with examples from history and recent headlines to offer new insights into who we are. Introducing the new science of cultural biology, born of advances in brain imaging, computer modeling, and genetics, Drs. Quartz and Sejnowski demystify the dynamic engagement between brain and world that makes us something far beyond the sum of our parts.

The authors show how our humanity unfolds in precise stages as brain and world engage on increasingly complex levels. Their discussion embraces shaping forces as ancient as climate change over millennia and events as recent as the terrorism and heroism of September 11 and offers intriguing answers to some of our most enduring questions, including why we live together, love, kill -- and sometimes lay down our lives for others.

The answers, it turns out, are surprising and paradoxical: many of the noblest aspects of human nature -- altruism, love, courage, and creativity -- are rooted in brain systems so ancient that we share them with insects, and these systems form the basis as well of some of our darkest destructive traits. The authors also overturn popular views of how brains develop. We're not the simple product of animal urges, "selfish" genes, or nature versus nurture. We survive by creating an ingenious web of ideas for making sense of our world -- a symbolic reality called culture. This we endow to later generations as our blueprint for survival.

Using compelling examples from history and contemporary life, the authors show how engagement with the world excites brain chemistry, which drives further engagement, which encourages the development of cultural complexity. They also share provocative ideas on how human development may be affected by changes in our culture. Their insights, grounded in science and far-reaching in their implications, are riveting reading for anyone interested in our past, present, and future.

Editorial Reviews

From Barnes & Noble
According to Quartz and Sejnowski, we aren't what we eat; we're what we encounter. Describing the new science of cultural biology, these two renowned neuroscientists explain how immersion in culture excites our brain chemistry and activates deeper engagement, which further shapes our culture and, we hope, ensures our prospects for species survival. Liars, Lovers and Heroes probes Homo sapiens' deepest nature, offering provocative ideas about how changing our culture may affect human development.
Publishers Weekly
Why do humans fall in love, create art, make war? Quartz, director of the Social Cognitive Neuroscience Laboratory at Cal Tech, and Sejnowski, director of the Computational Neurobiology Laboratory at the Salk Institute, argue that these and other capabilities are the result of biology and culture working together. Challenging the view that human brains are hardwired for certain behaviors, they believe instead that "[y]our experience with the world literally helps build your brain." In this wide-ranging and relatively nontechnical overview, the authors show how the human brain evolved to maximize flexibility, enabling us to thrive in a wide variety of circumstances. They discuss intelligence and learning, emotions, motivation, violence, and the importance of social bonds, linking cutting-edge neuroscience with social history and popular culture. Starting each chapter with an intriguing case history and spinning off into fascinating, if sometimes sketchily developed, presentations of related material, the book reads a bit like a made-for-TV serial documentary that concedes to short attention spans by highlighting the dramatic. As a result, some topics among them the discussion of violence receive useful but less than thorough treatment. Quartz and Sejnowski conclude with a thought-provoking chapter on the challenges of postmodern culture and globalization, suggesting that the findings of cultural biology can point the way toward creating societies that better meet our basic needs for positive social engagement. Their views, engagingly presented if sometimes controversial, will open up a hitherto specialized subject for a wider audience. (Nov. 12) Copyright 2002 Cahners Business Information.
Kirkus Reviews
What makes us human? A combination of genes and developmental programs interacting with an environment that shapes the brain across the life span, declare two California neuroscientists.

Dubbing their study of these complex interactions "cultural biology," Quartz (director of Caltech’s Social Cognitive Neuroscience Lab) and Sejnowski (director of the Salk Institute’s Computational Neurobiology Lab) condemn evolutionary psychology’s argument that we are cast adrift in modern society with our old hunter-gatherer savannah lifestyle. Neither naturists nor nurturists, the authors defend their not-unreasonable thesis by pointing to a detailed geological record showing rapid climate change. This called for maximum flexibility in adaptation, they contend, and probably helped build bigger brains, tools, and a habit of living in groups. Quartz and Sejnowski describe an infant’s survival mechanisms as an "internal guidance system" that will endure even as that individual’s "user’s guide to life" comes online as a result of the sociocultural shaping of the slow-to-mature prefrontal cortex and its anterior cingulate. These brain parts are key to planning, judging, and decision-making and are also linked to emotion and motivation. A derailment in these areas, specifically a hyperarousal of the orbitofrontal cortex, may be responsible for the mass suicide of cultists, group violence, and killings by high-school misfits, the authors conjecture. While they admit that the brain is more complex than we can fathom, they are ready to discourse on learning, love, intelligence, personality, and happiness, often pointing to anatomical pathways and neurochemicals as clues: low serotonin in depression andsuicide, oxytocin in love, and so on. They are also quite prescriptive in later chapters. What should we to do to achieve "successful aging" and rescue American society from increasing depression and isolation? Leave the TV and Net, go out and work in the community.

Smart authors with a lot of hot stuff to report on, but they should cool it a bit.

    A new look at the human condition

    This excellent new book tackles some of the oldest and most important questions about what it means to be human. The authors are prominent neuroscientists who know what they are talking about and write about it clearly and vividly. They set out to trace the findings and implications of a new science, cultural biology, which they believe can can "demystify the dynamic engagement between brain and world," and provide new insights into vital questions such as "why we live together, love, kill, and sacrifice ourselves for others." Cultural biology attempts to synthesize the contributions of biology--our genes, the course of development, and our brains--with the effects of environment and culture. In the authors hands, this approach often succeeds in breaking out of old dichotomies--nature vs. nurture, genetic vs. cultural determinism, humans as fundamentally social or fundamentally selfish--to provide a new, significantly more balanced understanding of how our biological raw material interacts with the world throughout our lives, not only in the womb or during early childhood, but in increasingly complex ways throughout our lives. The book lives up to its promise to shed new light on the rich interplay between genes and environment, the limits that our biology locks us into, and the potentials it provides. Although you may not agree with everything the authors say, Liars, Lovers, and Heroes will make you take a fresh look at the assumptions we all make about human nature. You may well walk away with genuine insights about why we humans love and hate, nurture and kill. The book is important, informative, and a pleasure to read. Robert Adler, author of Science Firsts: From the Creation of Science to the Science of Creation (Wiley, 2002).
