Touching A Nerve Our Brains Our Selves

A trailblazing philosopher’s exploration of the latest brain science—and its ethical and practical implications. What happens when we accept that everything we feel and think stems not from an immaterial spirit but from electrical and chemical activity in our brains? In this thought-provoking narrative—drawn from professional expertise as well as personal life experiences—trailblazing neurophilosopher Patricia S. Churchland grounds the philosophy of mind in the essential ingredients of biology. She reflects with humor on how she came to harmonize science and philosophy, the mind and the brain, abstract ideals and daily life. Offering lucid explanations of the neural workings that underlie identity, she reveals how the latest research into consciousness, memory, and free will can help us reexamine enduring philosophical, ethical, and spiritual questions: What shapes our personalities? How do we account for near-death experiences? How do we make decisions? And why do we feel empathy for others? Recent scientific discoveries also provide insights into a fascinating range of real-world dilemmas—for example, whether an adolescent can be held responsible for his actions and whether a patient in a coma can be considered a self. Churchland appreciates that the brain-based understanding of the mind can unnerve even our greatest thinkers. At a conference she attended, a prominent philosopher cried out, “I hate the brain; I hate the brain!” But as Churchland shows, he need not feel this way. Accepting that our brains are the basis of who we are liberates us from the shackles of superstition. It allows us to take ourselves seriously as a product of evolved mechanisms, past experiences, and social influences. And it gives us hope that we can fix some grievous conditions, and when we cannot, we can at least understand them with compassion.

What is morality? Where does it come from? And why do most of us heed its call most of the time? In Braintrust, neurophilosophy pioneer Patricia Churchland argues that morality originates in the biology of the brain. She describes the "neurobiological platform of bonding" that, modified by evolutionary pressures and cultural values, has led to human styles of moral behavior. The result is a provocative genealogy of morals that asks us to reevaluate the priority given to religion, absolute rules, and pure reason in accounting for the basis of morality. Moral values, Churchland argues, are rooted in a behavior common to all mammals--the caring for offspring. The evolved structure, processes, and chemistry of the brain incline humans to strive not only for self-preservation but for the well-being of allied selves--first offspring, then mates, kin, and so on, in wider and wider "caring" circles. Separation and exclusion cause pain, and the company of loved ones causes pleasure; responding to feelings of social pain and pleasure, brains adjust their circuitry to local customs. In this way, caring is apportioned, conscience molded, and moral intuitions instilled. A key part of the story is oxytocin, an ancient body-and-brain molecule that, by decreasing the stress response, allows humans to develop the trust in one another necessary for the development of close-knit ties, social institutions, and morality. A major new account of what really makes us moral, Braintrust challenges us to reconsider the origins of some of our most cherished values.

How do we determine right from wrong? Conscience illuminates the answer through science and philosophy. In her brilliant work Touching a Nerve, Patricia S. Churchland, the distinguished founder of neurophilosophy, drew from scientific research on the brain to understand its philosophical and ethical implications for identity, consciousness, free will, and memory. In Conscience, she explores how moral systems arise from our physical selves in combination with environmental demands. All social groups have ideals for behavior, even though ethics vary among different cultures and among individuals within each culture. In trying to understand why, Churchland brings together an understanding of the influences of nature and nurture. She looks to evolution to elucidate how, from birth, our brains are configured to form bonds, to cooperate, and to care. She shows how children grow up in society to learn, through repetition and rewards, the norms, values, and behavior that their parents embrace. Conscience delves into scientific studies, particularly the fascinating work on twins, to deepen our understanding of whether people have a predisposition to embrace specific ethical stands. Research on psychopaths illuminates the knowledge about those who abide by no moral system and the explanations science gives for these disturbing individuals. Churchland then turns to philosophy—that of Socrates, Aquinas, and contemporary thinkers like Owen Flanagan—to explore why morality is central to all societies, how it is transmitted through the generations, and why different cultures live by different morals. Her unparalleled ability to join ideas rarely put into dialogue brings light to a subject that speaks to the meaning of being human.
