According to the reigning competition-driven model of evolution, selfish behaviors that maximize an organism’s reproductive potential offer a fitness advantage over self-sacrificing behaviors—rendering unselfish behavior for the sake of others a mystery that requires extra explanation. Evolution, Games, and God addresses this conundrum by exploring how cooperation, working alongside mutation and natural selection, plays a critical role in populations from microbes to human societies. Inheriting a tendency to cooperate, argue the contributors to this book, may be as beneficial as the self-preserving instincts usually thought to be decisive in evolutionary dynamics.

Assembling experts in mathematical biology, history of science, psychology, philosophy, and theology, Martin Nowak and Sarah Coakley take an interdisciplinary approach to the terms “cooperation” and “altruism.” Using game theory, the authors elucidate mechanisms by which cooperation—a form of working together in which one individual benefits at the cost of another—arises through natural selection. They then examine altruism—cooperation which includes the sometimes conscious choice to act sacrificially for the collective good—as a key concept in scientific attempts to explain the origins of morality. Discoveries in cooperation go beyond the spread of genes in a population to include the spread of cultural transformations such as languages, ethics, and religious systems of meaning.

The authors resist the presumption that theology and evolutionary theory are inevitably at odds. Rather, in rationally presenting a number of theological interpretations of the phenomena of cooperation and altruism, they find evolutionary explanation and theology to be strongly compatible.

From Harvard University, one of the world’s preeminent institutions of
liberal education, comes a collection of essays sampling topics at the forefront of academia in the twenty-first century. Written by faculty members at the cutting edge of their fields, including such luminaries as Steven Pinker, Laurel Thatcher Ulrich, and Harry R. Lewis, these essays offer a clear and accessible overview of disciplines that are shaping the culture, and even the world.

The authors, among the most respected members of Harvard’s faculty, invite readers to explore subjects as diverse as religious literacy and Islam, liberty and security in cyberspace, medical science and epidemiology, energy resources, evolution, morality, human rights, global history, the dark side of the American Revolution, American literature and the environment, interracial literature, and the human mind. They summarize key developments in their fields in ways that will both entertain and edify those who seek an education beyond the confines of the classroom.

It is sometimes said that youth is wasted on the young. It could also be said that college, too often, is wasted on college students—that only after graduating does a former student come to appreciate learning. To those wishing to revisit the college classroom—as well as to those who never had the opportunity in the first place—this book gives a taste of the modern course at Harvard. The essays are stimulating and informative, and the annotated bibliographies accompanying each chapter provide invaluable guidance to the life-long learner who wants to pursue these fascinating topics in depth.

Are images an important means of recalling information from memory and solving problems? Or are images just display lights on the mind’s computer? In Image and Mind, Stephen Kosslyn makes an impressive case for the view that images are critically involved in the life of the mind. In a series of ingenious experiments, he provides hard evidence that people can construct elaborate mental images, search them for specific information, and perform such other internal operations as mental rotation. Kosslyn demonstrates that these results are best explained by a two-tiered model in which images are stored in abstract form in long-term memory and then assembled for internal display in much the way that images on a TV screen can be created from files in a computer memory.

Kosslyn shows how this model can be used to solve many of the persistent questions which have traditionally plagued theories of imagery that attempted to install imagery as the exclusive medium of mental representation.

Unlike any other work on imagery, Image and Mind provides an integrated account of most of the modern empirical results from imagery research within the framework of a coherent theory. The book also introduces a host of new experimental techniques and major hypotheses to guide future research. The result is a landmark book and a major event in the study of the mind.

The only way we can convey our thoughts in detail to another person is through verbal language. Does this imply that our thoughts ultimately rely on words? Is there only one way in which thoughts can occur? This ambitious book takes the contrary position, arguing that many possible "languages of thought" play different roles in the life of the mind.

"Language" is more than communication. It is also a means of representing information in both working and long-term memory. It provides a set of rules for combining and manipulating those representations.

A stellar lineup of international cognitive scientists, philosophers, and artists make the book's case that the brain is multilingual. Among topics discussed in the section on verbal languages are the learning of second languages, recovering language after brain damage, and sign language, and in the section on nonverbal languages, mental imagery, representations of motor activity, and the perception and representation of space.

Our subjective inner life is what really matters to us as human beings--and yet we know relatively little about how it arises. Over a long and distinguished career Benjamin Libet has conducted experiments that have helped us see, in clear and concrete ways, how the brain produces conscious awareness. For the first time, Libet gives his own account of these experiments and their importance for our understanding of consciousness.

Most notably, Libet's experiments reveal a substantial delay--the "mind time" of the title--before any awareness affects how we view our mental activities. If all conscious awarenesses are preceded by unconscious processes, as Libet observes, we are forced to conclude that unconscious processes initiate our conscious experiences. Freely voluntary acts are found to be initiated unconsciously before an awareness of wanting to act--a discovery with profound ramifications for our understanding of free will.

How do the physical activities of billions of cerebral nerve cells give rise to an integrated conscious subjective awareness? How can the subjective mind affect or control voluntary actions? Libet considers these questions, as well as the implications of his discoveries for the nature of the soul, the identity of the person, and the relation of the non-physical subjective mind to the physical brain that produces it. Rendered in clear, accessible language, Libet's experiments and theories will allow interested amateurs and experts alike to share the experience of the extraordinary discoveries made in the practical study of consciousness.
