Life is a property of the universe. We may not know how it began or where else it exists, but we have come to know a great deal about how it relates to stars, planets, and the larger cosmos. In clear and compelling terms, this book shows how the emerging field of astrobiology investigates the nature of life in space. How did life begin? How common is it? Where do we fit in? These are the important questions that astrobiology seeks to answer.

A truly interdisciplinary endeavor, astrobiology looks at the evidence of astronomy, biology, physics, chemistry, and a host of other fields. A grand narrative emerges, beginning from the smallest, most common particles yet producing amazing complexity and order. Lucas Mix is a congenial guide through the depths of astrobiology, exploring how the presence of planets around other stars affects our knowledge of our own; how water, carbon, and electrons interact to form life as we know it; and how the processes of evolution and entropy act upon every living thing.

This book also reveals that our understanding and our context are deeply intertwined. It shows how much astrobiology can tell us about who we are—as a planet, as a species, and as individuals.

The Soviet agronomist Trofim Lysenko became one of the most notorious figures in twentieth-century science after his genetic theories were discredited decades ago. Yet some scientists, even in the West, now claim that discoveries in the field of epigenetics prove that he was right after all. Seeking to get to the bottom of Lysenko’s rehabilitation in certain Russian scientific circles, Loren Graham reopens the case, granting his theories an impartial hearing to determine whether new developments in molecular biology validate his claims.

In the 1930s Lysenko advanced a “theory of nutrients” to explain plant development, basing his insights on experiments which, he claimed, showed one could manipulate environmental conditions such as temperature to convert a winter wheat variety into a spring variety. He considered the inheritance of acquired characteristics—which he called the “internalization of environmental conditions”—the primary mechanism of heredity. Although his methods were slipshod and his results were never duplicated, his ideas fell on fertile ground during a time of widespread famine in the Soviet Union.

Recently, a hypothesis called epigenetic transgenerational inheritance has suggested that acquired characteristics may indeed occasionally be passed on to offspring. Some biologists dispute the evidence for this hypothesis. Loren Graham examines these arguments, both in Russia and the West, and shows how, in Russia, political currents are particularly significant in affecting the debates.

An exploration of how plant behavior and adaptation offer valuable insights for human thriving.

We know that plants are important. They maintain the atmosphere by absorbing carbon dioxide and producing oxygen. They nourish other living organisms and supply psychological benefits to humans as well, improving our moods and beautifying the landscape around us. But plants don’t just passively provide. They also take action.

Beronda L. Montgomery explores the vigorous, creative lives of organisms often treated as static and predictable. In fact, plants are masters of adaptation. They “know” what and who they are, and they use this knowledge to make a way in the world. Plants experience a kind of sensation that does not require eyes or ears. They distinguish kin, friend, and foe, and they are able to respond to ecological competition despite lacking the capacity of fight-or-flight. Plants are even capable of transformative behaviors that allow them to maximize their chances of survival in a dynamic and sometimes unfriendly environment.

Lessons from Plants enters into the depth of botanic experience and shows how we might improve human society by better appreciating not just what plants give us but also how they achieve their own purposes. What would it mean to learn from these organisms, to become more aware of our environments and to adapt to our own worlds by calling on perception and awareness? Montgomery’s meditative study puts before us a question with the power to reframe the way we live: What would a plant do?

Alone on the endless red-sand desert in the Australian outback, tracking Varanus giganteus, the perentie lizard that grows to be more than six feet long...for desert rat Eric Pianka, such adventures have led to a satisfying, if unusual, way of life, as well as a distinguished career as a field biologist.

In The Lizard Man Speaks, Pianka recounts more than thirty years of adventures in reptile studies. He tells of "lizarding" in the North American deserts, the Kalahari Desert of southern Africa, and the Great Victoria Desert in Western Australia. His vivid imagery draws the reader into a world where lions lurk in the darkness beyond a gecko hunter's lights, where being stranded by car trouble miles from the last outpost is a constant danger, and where the wilderness still deserves to be called wild.

Along the way, Pianka provides much general information about lizard ecology, the fire succession cycle, and the interaction of humans with the landscape. And he reveals the springs of his own determined spirit and love of solitude, describing a near-fatal boyhood accident and its shaping and character-building effect on the life that followed.

Other than that it tastes delicious with butter, what do you know about the knobbily-armoured, scarlet creature staring back at you from your fancy dinner plate? From ocean to stock pot, there are two sides to every animal story. For instance, since there are species of lobsters without claws, how exactly do you define a lobster? And how did a pauper’s food transform into a meal synonymous with a luxurious splurge? To answer these questions on behalf of lobster the animal is Richard J. King, a former fishmonger and commercial lobsterman, who has chronicled the creature’s long natural history. 
 

Part of the Animal series, King’s Lobster takes us on a journey through the history, biology, and culture of lobsters, including the creature’s economic and environmental status worldwide. He describes the evolution of technologies to capture these creatures and addresses the ethics of boiling them alive. Along the way, King also explores the salacious lobster palaces of the 1920s, the animal’s thousand-year status as an aphrodisiac, and how the lobster has inspired numerous artists, writers, and thinkers including Aristotle, Dickens, Thoreau, Dalí, and Woody Allen.

Whether you want to liberate lobsters from their supermarket tanks or crack open their claws, this book is an essential read, describing the human connection to the lobster from his ocean home to the dinner table.

Based on years of field work and the examination of thousands of museum specimens, The Lizards, Crocodiles, and Turtles of Honduras is the final installment of a series of volumes by James R. McCranie documenting the amphibians and reptiles of Honduras.

Thoroughly illustrated by color photographs and maps of geographic distribution, the book describes in detail 86 species of Honduran lizards, crocodilians, and turtles. Identification keys in both English and Spanish allow the ready identification of all species, and discussions of conservation status review current threats to all species. The publication of this work represents the completion of the most comprehensive and detailed study of the amphibian and reptilian faunas of any country in Latin America.

Trundling along in essentially the same form for some 220 million years, turtles have seen dinosaurs come and go, mammals emerge, and humankind expand its dominion. Is it any wonder the persistent reptile bested the hare? In this engaging book physiologist Donald Jackson shares a lifetime of observation of this curious creature, allowing us a look under the shell of an animal at once so familiar and so strange.

Here we discover how the turtle’s proverbial slowness helps it survive a long, cold winter under ice. How the shell not only serves as a protective home but also influences such essential functions as buoyancy control, breathing, and surviving remarkably long periods without oxygen, and how many other physiological features help define this unique animal. Jackson offers insight into what exactly it’s like to live inside a shell—to carry the heavy carapace on land and in water, to breathe without an expandable ribcage, to have sex with all that body armor intervening.

Along the way we also learn something about the process of scientific discovery—how the answer to one question leads to new questions, how a chance observation can change the direction of study, and above all how new research always builds on the previous work of others. A clear and informative exposition of physiological concepts using the turtle as a model organism, the book is as interesting for what it tells us about scientific investigation as it is for its deep and detailed understanding of how the enduring turtle “works.”

Tortoises may be the first family of higher animals to become extinct in the coming decades. They are losing the survival race because of what distinguishes them, in particular their slow, steady pace of life and reproduction.

The Last Tortoise offers an introduction to these remarkable animals and the extraordinary adaptations that have allowed them to successfully populate a diverse range of habitats—from deserts to islands to tropical forests. The shields that protect their shoulders and ribs have helped them evade predators. They are also safeguarded by their extreme longevity and long period of fertility. Craig Stanford details how human predation has overcome these evolutionary advantages, extinguishing several species and threatening the remaining forty-five.

At the center of this beautifully written work is Stanford’s own research in the Mascarene and Galapagos Islands, where the plight of giant tortoise populations illustrates the threat faced by all tortoises. He addresses unique survival problems, from genetic issues to the costs and benefits of different reproductive strategies. Though the picture Stanford draws is bleak, he offers reason for hope in the face of seemingly inevitable tragedy. Like many intractable environmental problems, extinction is not manifest destiny. Focusing on tortoise nurseries and breeding facilities, the substitution of proxy species for extinct tortoises, and the introduction of species to new environments, Stanford’s work makes a persuasive case for the future of the tortoise in all its rich diversity.

Children from six to twelve are introduced to the most frequently seen and interesting Texas birds. Youngsters can color eye-catching line drawings of various birds in typical habitats, while an easy-to-read text gives important facts about the birds, and several fun games are instructive and challenging.

Sexual combat is not a monopoly of the human species. As Sarah Blaffer Hrdy argues in this spellbinding book, war between male and female animals has deep roots in evolutionary history. Her account of family life among hanuman langurs—the black-faced, gray monkeys inhabiting much of the Indian subcontinent—is written with force, wit, and at times, sorrow.

Male hanumans, in pursuit of genetic success, routinely kill babies sired by their competitors. The mothers of endangered infants counter with various strategems to deceive the males and prevent destruction of their own offspring. Competition and selfishness are dominant themes of langur society. Competition among males for access to females, competition among females for access to food resources, and disregard by one female for the well-being of another’s infant—these are some very common examples. Yet there are also moments of heroic self-sacrifice, as when an elderly female rushes to defend her troop and its babies from an invading, infancticidal male.

The Langurs of Abu is the first book to analyze behavior of wild primates from the standpoint of both sexes. It is also a poignant and sophisticated exploration of primate behavior patterns from a feminist point of view. This book may inspire controversy; it will certainly be read with pleasure by anyone interested in animal behavior.

Camelids are vital to the cultures and economies of the Andes. The animals have also been at the heart of ecological and social catastrophe: Europeans overhunted wild vicuña and guanaco and imposed husbandry and breeding practices that decimated llama and alpaca flocks that had been successfully tended by Indigenous peoples for generations. Yet the colonial encounter with these animals was not limited to the New World. Llamas beyond the Andes tells the five-hundred-year history of animals removed from their native habitats and transported overseas.

Initially Europeans prized camelids for the bezoar stones found in their guts: boluses of ingested matter that were thought to have curative powers. Then the animals themselves were shipped abroad as exotica. As Europeans and US Americans came to recognize the economic value of camelids, new questions emerged: What would these novel sources of protein and fiber mean for the sheep industry? And how best to cultivate herds? Andeans had the expertise, but knowledge sharing was rarely easy. Marcia Stephenson explores the myriad scientific, commercial, and cultural interests that have attended camelids globally, making these animals a critical meeting point for diverse groups from the North and South.

Anna Morandi Manzolini (1714-74), a woman artist and scientist, surmounted meager origins and limited formal education to become one of the most acclaimed anatomical sculptors of the Enlightenment. The Lady Anatomist tells the story of her arresting life and times, in light of the intertwined histories of science, gender, and art that complicated her rise to fame in the eighteenth century.

Examining the details of Morandi’s remarkable life, Rebecca Messbarger traces her intellectual trajectory from provincial artist to internationally renowned anatomical wax modeler for the University of Bologna’s famous medical school. Placing Morandi’s work within its cultural and historical context, as well as in line with the Italian tradition of anatomical studies and design, Messbarger uncovers the messages contained within Morandi’s wax inscriptions, part complex theories of the body and part poetry. Widely appealing to those with an interest in the tangled histories of art and the body, and including lavish, full-color reproductions of Morandi’s work, The Lady Anatomist is a sophisticated biography of a true visionary.

For its size, the larynx is the most complex and versatile mechanical device in the body. In this remarkable book, a distinguished medical illustrator and a world authority on laryngeal biomechanics collaborate to provide both an atlas and a treatise on the behavior of the larynx. In separate chapters, the authors consider the functions of the larynx—as safeguard for the free passage of air, to protect the airway from invasion, as a plug that resists expiration during effort, and as the instrument of speech and song. They replace the traditional view of the larynx as a sphincter with a more accurate model. The laryngeal tissues are seen as folding and unfolding in response to respiratory excursion of the trachea, action of intrinsic and extrinsic laryngeal muscles, the respiratory air current, and the elastic recoil of ligaments, membranes, and articular capsules.

The illustrations include unretouched xrays, halftone sketches, structural drawings, and diagrams; together they present as complete a picture as possible of the larynx in all its various functional states. Innovative and systematic, the work forms the basis for planning radical and reconstructive surgery, quantitative approaches in voice therapy, treatment of laryngospasm in anesthesia without use of relaxants, and design of an artificial larynx.

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.

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.

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.

Kermit the Frog famously said that it isn’t easy being green, and in Living at Micro Scale David Dusenbery shows that it isn’t easy being small—existing at the size of, say, a rotifer, a tiny multicellular animal just at the boundary between the visible and the microscopic. “Imagine,” he writes, “stepping off a curb and waiting a week for your foot to hit the ground.” At that scale, we would be small enough to swim inside the letter O in the word “rotifer.” What are the physical consequences of life at this scale? How do such organisms move, identify prey and predators and (if they’re so inclined) mates, signal to one another, and orient themselves?

In clear and engaging prose, Dusenbery uses straightforward physics to demonstrate the constraints on the size, shape, and behavior of tiny organisms. While recounting the historical development of the basic concepts, he unearths a corner of microbiology rich in history, and full of lessons about how science does or does not progress. Marshalling findings from different fields to show why tiny organisms have some of the properties they are found to have, Dusenbery shows a science that doesn’t always move triumphantly forward, and is dependent to a great extent on accident and contingency.

Microbes create medicines, filter waste water, and clean pollution. They give cheese funky flavors, wines complex aromas, and bread a nutty crumb. Life at the Edge of Sight is a stunning visual exploration of the inhabitants of an invisible world, from the pioneering findings of a seventeenth-century visionary to magnificent close-ups of the inner workings and cooperative communities of Earth’s most prolific organisms.

Using cutting-edge imaging technologies, Scott Chimileski and Roberto Kolter lead readers through breakthroughs and unresolved questions scientists hope microbes will answer soon. They explain how microbial studies have clarified the origins of life on Earth, guided thinking about possible life on other planets, unlocked evolutionary mechanisms, and helped explain the functioning of complex ecosystems. Microbes have been harnessed to increase crop yields and promote human health.

But equally impressive, Life at the Edge of Sight opens a beautiful new frontier for readers to explore through words and images. We learn that there is more microbial biodiversity on a single frond of duckweed floating in a Delft canal than the diversity of plants and animals that biologists find in tropical rainforests. Colonies with millions of microbes can produce an array of pigments that put an artist’s palette to shame. The microbial world is ancient and ever-changing, buried in fossils and driven by cellular reactions operating in quadrillionths of a second. All other organisms have evolved within this universe of microbes, yielding intricate beneficial symbioses. With two experts as guides, the invisible microbial world awaits in plain sight.

Praised as "one of those rare scientific books that can be read both for pleasure and instruction" when it was first published, The Life of Yeasts now appears in a new edition incorporating the exciting developments of the last decade. Nowhere else is there an introduction to this complex group of organisms that is as succinct, clear, and useful. Reviewing the first edition in Nature, A. H. Cook welcomed it as a "simple but wide-ranging account of a field which for various reasons has hitherto mostly been described only in a few specialized texts or in many respects only piecemeal in original publications."

This book is written for the nonspecialist who wishes to understand the yeasts, but not necessarily to become an expert on them. The new edition covers recent and major advances in the morphology, physiology, genetics, and ecology of these organisms, which have long been important in commerce and medicine and are ever more studied in the laboratory as prototypical eukaryotes.

Leaving a Legacy: Lessons from the Writings of Daniel Drake is a selective collection of excerpts from the vast writings from the nineteenth-century doctor and medical pioneer Daniel Drake. From Drake’s life, documented here in his own words from excerpts of lectures, personal journal entries, presentations, speeches, books, and letters to his children, readers learn about the scope of his accomplishments in medicine, contributions to his community, and dedication to his family. Diller goes beyond biography to contextualize Drake’s life choices and what made him a role model for today’s physicians. Diller selected one hundred and eighty thematically arranged excerpts, which he paired with original reflection questions to guide the reader through thought-provoking prompts. In doing so, Diller presents the lessons from Drake’s remarkable life and work as a guide for others who wish to build an enduring legacy.

An authoritative introduction to bioethics, Life Choices examines a comprehensive range of ethical questions and brings together some of the most probing and instructive essays published in the field.

Some of the articles are classics in the literature of bioethics, while others address current issues. Topics include moral decision making, abortion, euthanasia and assisted suicide, life-sustaining technologies, organ transplantation, reproductive technologies, and the allocation of health care resources.

This second edition features new sections on the goals and allocation of medicine and on the cloning of human beings. It also includes new articles on genetics, the duty to die, and ethical theory.

Written by the foremost authorities in bioethics, Life Choices provides a comprehensive introduction to the field. Instructors who have used the first edition as a text will welcome this new, updated edition. Scholars and health care practitioners will find it useful as a valuable reference on a wide range of bioethical issues.

Take a random walk through your life and you’ll find it is awash in industrial, often toxic, chemicals. Sip water from a plastic bottle and ingest bisphenol A. Prepare dinner in a non-stick frying pan or wear a layer of Gore-Tex only to be exposed to perfluorinated compounds. Hang curtains, clip your baby into a car seat, watch television—all are manufactured with brominated flame-retardants.

Cosmetic ingredients, industrial chemicals, pesticides, and other compounds enter our bodies and remain briefly or permanently. Far too many suspected toxic hazards are unleashed every day that affect the development and function of our brain, immune system, reproductive organs, or hormones. But no public health law requires product testing of most chemical compounds before they enter the market. If products are deemed dangerous, toxicants must be forcibly reduced or removed—but only after harm has been done.

In this scientifically rigorous legal analysis, Carl Cranor argues that just as pharmaceuticals and pesticides cannot be sold without pre-market testing, other chemical products should be subject to the same safety measures. Cranor shows, in terrifying detail, what risks we run, and that it is entirely possible to design a less dangerous commercial world.

At the turn of the twenty-first century, the United States contended with a state-run biological warfare program, bioterrorism, and a pandemic. Together, these threats spurred large-scale government demand for new vaccines, but few have materialized. A new anthrax vaccine has been a priority since the first Gulf War, but twenty years and a billion dollars later, the United States still does not have one. This failure is startling.

Historically, the United States has excelled at responding to national health emergencies. World War II era programs developed ten new or improved vaccines, often in time to meet the objectives of particular military missions. Probing the history of vaccine development for factors that foster timely innovation, Kendall Hoyt discovered that vaccine innovation has been falling, not rising, since World War II. This finding is at odds with prevailing theories of market-based innovation and suggests that a collection of nonmarket factors drove mid-century innovation. Ironically, many late-twentieth-century developments that have been celebrated as a boon for innovation—the birth of a biotechnology industry and the rise of specialization and outsourcing—undercut the collaborative networks and research practices that drove successful vaccine projects in the past.

Hoyt’s timely investigation teaches important lessons for our efforts to rebuild twenty-first-century biodefense capabilities, especially when the financial payback for a particular vaccine is low, but the social returns are high.

Let Them Go Free offers families a way to cope with a problem particular to our time: what to do when medical treatment sustains life but does not cure or resuscitate a critically ill loved one. This straightforward and empathic guide helps such families affirm that their choice to remove life support is morally acceptable, warranted, and made in the spirit of love and care for the patient.

With an emphasis on maintaining openness and trust among all involved in the decision-making process, this helpful guide skillfully addresses the questions that must be asked to assess the best course of care for a loved one:

• What is the patient’s medical condition?

• What are the medical options?

• Has the patient expressed any wishes regarding his or her treatment?

• What if the patient hasn’t expressed any wishes regarding treatment?

• Do we have to do everything possible to keep the patient alive?

• Do we have to use artificial means of feeding?

• How do we handle disagreements?

• What should we do about donating organs?

Let Them Go Free also includes an ecumenical prayer service to be conducted as life support is withdrawn. Woven with readings and prayers from Hebrew and Christian scripture, the service is intended to give family and friends a moment to express their love for the patient, to say goodbye, and to find a sense of closure as they embark on the first stage of the grieving process.

An arresting memoir of love and unbending religion, toxicity and disease, and one family’s desperate wait for a miracle that never came.

Kathleen Dorothy Blackburn was the oldest of five children, a twelve-year-old from Lubbock, Texas, whose evangelical family eschewed public education for homeschooling, and wove improbable scientific theories into literal interpretations of the Bible. Then her father, a former air force pilot, was diagnosed with cancer at the age of thirty-eight, and, “it was like throwing gasoline on the Holy Spirit.” Stirred by her mother, the family committed to an extreme diet and sought deliverance from equally extreme sources: a traveling tent preacher, a Malaysian holy man, a local faith-healer who led services called “Miracles on 34th Street.”

What they didn’t know at the time was that their lives were entangled with a larger, less visible environmental catastrophe. Fire-fighting foams containing carcinogenic compounds had contaminated the drinking water of every military site where her father worked. Commonly referred to as “forever chemicals,” the presence of PFAS in West Texas besieged a landscape already burdened with vanishing water, taking up residence in wells and in the bloodstreams of people who lived there. An arresting portrait of the pernicious creep of decline, and a powerful cry for environmental justice, Loose of Earth captures the desperate futility and unbending religious faith that devastated a family, leaving them waiting for a miracle that would never come.

Hilde Bruch sets out to accomplish what has, until now, been virtually impossible—the teaching of psychotherapy by use of the written word, communicating the wisdom of a lifetime. Perhaps Dr. Bruch’s unique success at a task that has been tried and tried again, only to result in stereotyped dos and don’ts, stems from her own learning experiences with two great teachers: Harry Stack Sullivan and Frieda Fromm-Reichmann.

Dr. Bruch shares her knowledge of the essential purpose of intensive psychotherapy as it has been shaped over her many years as a psychiatrist, psychoanalyst, and teacher. She sets forth a theoretical frame in straightforward and unmystical language without minimizing the complexities of demand that therapy makes on both patient and therapist.

The reader accompanies the therapist from his first encounter with the stranger who comes to him with his trouble through the various steps that lead to the resolution of the problems. The patient is viewed as a participant in a multifaceted system of many experiences and people, not as an individual isolated from the world around him. In Dr. Bruch’s conception, psychotherapy is a situation where two people interact and try to come to an understanding of one another, with the specific goal of accomplishing something beneficial for the complaining person. The factors that help or hinder the attainment of this interaction are spelled out in the book, and the entire process of learning psychotherapy is thereby illuminated.
