Facts are facts, we often say with certainty; but values--well, they're relative. But every day we are confronted with situations where these simple distinctions begin to blur--whether our concerns are the roots of crime and violence, the measure of intelligence, the causes of disease, the threat and promise of genetic engineering. Where do our "facts" end and our "values" begin?

Recent developments in neuroscience have begun to shed light on this confusion, by radically revising our notions of where human nature ends and human nurture begins. As Edward Hundert--a philosopher, psychiatrist, and award-winning educator--makes clear in this eloquent interdisciplinary work, the newly emerging model for the interactions of brain and environment has enormous implications for our understanding of who we are, how we know, and what we value.

Lessons from an Optical Illusion is a bold modern recasting of the age-old nature-nurture debate, informed by revolutionary insights from brain science, artificial intelligence, psychiatry, linguistics, evolutionary biology, child development, ethics, and even cosmology. As this radical new synthesis unfolds, we are introduced to characters ranging from Immanuel Kant to Gerald Edelman, from Charles Darwin to Sigmund Freud, from Jean Piaget to Stephen Hawking, from Socrates to Jonas Salk. Traversing the nature-nurture terrain, we encounter simulated robots, optical illusions, game theory, the anthropic principle, the prisoner's dilemma, and the language instinct. In the course of Hundert's wide-ranging exploration, the comfortable dichotomies that once made sense (objectivity-subjectivity, heredity-environment, fact-value) break down under sharp analysis, as he reveals the startling degree to which facts are our creations and values are woven into the fabric of the world. Armed with an updated understanding of how we became who we are and how we know what we know, readers are challenged to confront anew the eternal question of what it means to live a moral life.

A majority of evolutionary biologists believe that we now can envision our biological predecessors—not the first, but nearly the first, living beings on Earth. Life from an RNA World is about these vanished forebears, sketching them in the distant past just as their workings first began to resemble our own. The advances that have made such a pursuit possible are rarely discussed outside of bio-labs. So here, says author Michael Yarus, is an album for interested non-biologists, an introduction to our relatives in deep time, slouching between the first rudimentary life on Earth and the appearance of more complex beings.

The era between, and the focus of Yarus’ work, is called the RNA world. It is RNA (ribonucleic acid)—long believed to be a mere biologic copier and messenger—that offers us this glimpse into our ancient predecessors. To describe early RNA creatures, here called “ribocytes” or RNA cells, Yarus deploys some basics of molecular biology. He reviews our current understanding of the tree of life, examines the structure of RNA itself, explains the operation of the genetic code, and covers much else—all in an effort to reveal a departed biological world across billions of years between its heyday and ours.

Courting controversy among those who question the role of “ribocytes”—citing the chemical fragility of RNA and the uncertainty about the origin of an RNA synthetic apparatus—Yarus offers an invaluable vision of early life on Earth. And his book makes that early form of life, our ancestor within, accessible to all of us.

A rigorous and scientific analysis of the myriad possibilities of life beyond our planet.

“Are we alone in the universe?” This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life.

Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Avi Loeb tackle three areas of interest in hunting for life “out there”: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see.

Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.

All humans share three origins: the beginning of our individual lives, the appearance of life on Earth, and the formation of our planetary home. Life through Time and Space brings together the latest discoveries in both biology and astronomy to examine our deepest questions about where we came from, where we are going, and whether we are alone in the cosmos.

A distinctive voice in the growing field of astrobiology, Wallace Arthur combines embryological, evolutionary, and cosmological perspectives to tell the story of life on Earth and its potential to exist elsewhere in the universe. He guides us on a journey through the myriad events that started with the big bang and led to the universe we inhabit today. Along the way, readers learn about the evolution of life from a primordial soup of organic molecules to complex plants and animals, about Earth’s geological transformation from barren rock to diverse ecosystems, and about human development from embryo to infant to adult. Arthur looks closely at the history of mass extinctions and the prospects for humanity’s future on our precious planet.

Do intelligent aliens exist on a distant planet in the Milky Way, sharing the three origins that characterize all life on Earth? In addressing this question, Life through Time and Space tackles the many riddles of our place and fate in the universe that have intrigued human beings since they first gazed in wonder at the nighttime sky.

Jurij Striedter provides a dynamic introduction to and critique of Russian Formalism and Czech Structuralism. He makes clear the pathbreaking contribution of these European schools to modern literary theory and criticism, placing them in their contemporary contexts and at the same time relating them to ongoing debates in America.

Striedter gives an authoritative account of the development of Russian Formalism from its birth around 1915 through its forced end in the late 1920s, focusing on the contributions of Roman Jakobson, Mikhail Bakhtin, and others to the theory and analysis of literary history, literary genres and narrative prose. He compares the concepts of the literary work, literature as system, and literary evolution in both Russian Formalism and Czech Structuralism to show how these early formalistic approaches led to an elaborated structuralist and semiotic concept of literature as a historically changing system correlated to society and cultural change. He sets forth the work of Jan Mukarovsky and Felix Vodicka, whose Czech Structuralist theory of literary evolution and literary reception (or reader response) anticipated much recent theorizing.

Finally, Striedter brings these ideas into play by showing how they can contribute to the debate of the last few years in North America and Europe about the key issue of literary evaluation. This book and the theories it discusses challenge our contemporary understanding of literature, its history, and its functions in society and human life.

In a new approach to interdisciplinary literary theory, Literature, Analytically Speaking integrates literary studies with analytic aesthetics, girded by neo-Darwinian evolution. Scrutinizing narrative fiction through a lens provided by analytic philosophy, revered literary theorist Peter Swirski puts new life into literary theory while fashioning a set of practical guidelines for critics in the interpretive trenches.

Dismissing critical inquirers who deny intention its key role in the study of literary reception, Swirski extends the defense of intentionality to art and to human behavior in general. In the process, Swirski takes stock of the recent work in evolutionary theory, arguing that the analysis of narrative truth may be grounded in the neo-Darwinian paradigm which forms the empirical backbone behind his analytic approach. Literature, Analytically Speaking provides a series of precepts designed to capture the ways in which we do interpret (and ought to interpret) works of literature. Reflecting a resounding shift from the poststructuralist paradigm, Swirski's lively and colorful presentation, backed up by a dazzling variety of examples and case studies, reconceptualizes the aesthetics of literature and literary studies.

Though we have other distinguishing characteristics (walking on two legs, for instance, and relative hairlessness), the brain and the behavior it produces are what truly set us apart from the other apes and primates. And how this three-pound organ composed of water, fat, and protein turned a mammal species into the dominant animal on earth today is the story John S. Allen seeks to tell.

Adopting what he calls a “bottom-up” approach to the evolution of human behavior, Allen considers the brain as a biological organ; a collection of genes, cells, and tissues that grows, eats, and ages, and is subject to the direct effects of natural selection and the phylogenetic constraints of its ancestry. An exploration of the evolution of this critical organ based on recent work in paleo­anthropology, brain anatomy and neuroimaging, molecular genetics, life history theory, and related fields, his book shows us the brain as a product of the contexts in which it evolved: phylogenetic, somatic, genetic, ecological, demographic, and ultimately, cultural-linguistic. Throughout, Allen focuses on the foundations of brain evolution rather than the evolution of behavior or cognition. This perspective demonstrates how, just as some aspects of our behavior emerge in unexpected ways from the development of certain cognitive capacities, a more nuanced understanding of behavioral evolution might develop from a clearer picture of brain evolution.

Alison Jolly believes that biologists have an important story to tell about being human—not the all-too-familiar tale of selfishness, competition, and biology as destiny but rather one of cooperation and interdependence, from the first merging of molecules to the rise of a species inextricably linked by language, culture, and group living. This is the story that unfolds in Lucy’s Legacy, the saga of human evolution as told by a world-renowned primatologist who works among the female-dominant ringtailed lemurs of Madagascar.

We cannot be certain that Lucy was female—the bones themselves do not tell us. However, we do know, as Jolly points out in this erudite, funny, and informative book, that the females who came after Lucy—more adept than their males in verbal facility, sharing food, forging links between generations, migrating among places and groups, and devising creative mating strategies—played as crucial a role in the human evolutionary process as “man” ever did. In a book that takes us from the first cell to global society, Jolly shows us that to learn where we came from and where we go next, we need to understand how sex and intelligence, cooperation and love, emerged from the harsh Darwinian struggle in the past, and how these natural powers may continue to evolve in the future.

The League of United Latin American Citizens (LULAC) is one of the best-known and active national organizations that represent Mexican Americans and their political interests. Since its founding in Corpus Christi, Texas, in 1929, it has served as a vehicle through which Mexican Americans can strive for equal rights and economic assimilation into Anglo American society.

This study is the first comprehensive political history of LULAC from its founding through the 1980s. Márquez explores the group’s evolution from an activist, grassroots organization in the pre– and post–World War II periods to its current status as an institutionalized bureaucracy that relies heavily on outside funding to further its politically conservative goals. His information is based in part on many primary source materials from the LULAC archives at the University of Texas at Austin, the Houston Public Library, and the University LULAC publications, as well as interviews with present and past LULAC activists.

Márquez places this history within the larger theoretical framework of incentive theory to show how changing, and sometimes declining, membership rewards have influenced people’s participation in LULAC and other interest groups over time. Ironically, as of 1988, LULAC could claim fewer than 5,000 dues-paying members, yet a dedicated and skillful leadership secured sufficient government and corporate monies to make LULAC one of the most visible and active groups in Mexican American politics.

Given the increasing number of interest groups and political action committees involved in national politics in the United States, this case study of a political organization’s evolution will be of interest to a wide audience in the political and social sciences, as well as to students of Mexican American and ethnic studies.
