Soul Made Flesh is the remarkable untold story of a dramatic turning point in history -- the exciting discovery of how the human brain works. In an unprecedented examination of how the secrets of the brain were revealed in seventeenth-century England, award-winning author Carl Zimmer tells an extraordinary tale that unfurls against a deadly backdrop of civil war, plague, and the Great Fire of London. At the beginning of that turbulent century, no one knew how the brain worked or even what it looked like intact. By the century's close, the science of the brain had taken root, helping to overturn many of the most common misconceptions and dominant philosophies about man, God, and the universe. Presiding over the rise of this new scientific paradigm was the founder of modern neurology, Thomas Willis, a fascinating, sympathetic, even heroic figure who stands at the center of an extraordinary group of scientists and philosophers known as the Oxford circle. Chronicled here in vivid detail are their groundbreaking revelations and often gory experiments that first enshrined the brain as the chemical engine of reason, emotion, and madness -- indeed as the very seat of the human soul.

Called "as fine a science essayist as we have" by The New York Times, Zimmer tells the story of this scientific revolution through the lives of a colorful array of alchemists, mystics, utopians, spies, revolutionaries, and kings. He recreates the religious, ethical, and scientific struggles involved in the pioneering autopsies of the brain carried out by Thomas Willis; the discovery of the circulation of blood by William Harvey and his flight from London with his besieged king, Charles I; René Descartes's persecution by Catholics and Protestants alike for his views of the brain and soul; and the experiments and personal dramas of gifted men who forever changed the way science is practiced as they simultaneously upended our view of our human selves and our place in the world.

In this distant mirror to our own time of continuing scientific revolution and worldwide social upheaval, Zimmer brings to life the painstaking, innovative discoveries of Willis and his contemporaries -- the taproots of the amazing work of today's neuroscientists, who continue to explore the brain, revealing the hidden workings of emotions, memories, and consciousness. Graced with beautiful illustrations by Christopher Wren, Soul Made Flesh conveys a contagious appreciation for the wonder of the brain, its structure, its many marvelous functions, and the implications for human identity, mind, and morality. It is the definitive history of the dawn of a world-changing science and attitude -- the age of the brain and modern consciousness.

Soul Made Flesh: The Discovery of the Brain--and How it Changed the World PDF

Soul Made Flesh is a masterful blend of science, history and philosophy. Carl Zimmer weaves a fascinating narrative around an overlooked historical moment - the discovery of the brain - by looping back and forth through the centuries from ancient Greece to the new millennium while keeping his gaze fixed on 17th century England. As someone schooled in the classics, whose college curriculum consisted wholly of the Great Books, I found Zimmer's new book particularly satisfying to read. Soul Made Flesh is far more than a gallop through history. It goes well beyond identifying who was influenced by who, what I call the "connecting the dots through time" approach often conveyed in reverential tones by writers who have read only secondary sources of Aristotle, Descartes or Locke. Zimmer's book breathes life into the classics by allowing the reader to "overhear" Willis and his Oxford Circle peers examining, questioning and arguing about these texts even as they toil to expand anatomical knowledge beyond all previous bounds.

As I neared the end of Soul Made Flesh, I happened to read a Boston Globe Magazine interview with Andrea Barrett, author of The Voyage of the Narwhal and, like Zimmer, a gifted science essayist. I was struck by a passage in which Barrett talks about "the unspoken disappointment of science" - research stolen or lost, specimens left in sunken ships, a life's worth of work made irrelevant by changing times. "I think about [loss] a lot. It's a very, very real part of science, but it's not the part that gets passed down," says Barrett. "We know the stories of famous scientists, but we don't hear the stories of people working hard and passionately half a tier down." Barrett could have been talking about Zimmer's book as much as her own.

The American writer Carl Zimmer has written a brilliant book on Thomas Willis (1621-75), the founder of neurology. Willis discovered the human brain's role and importance, and was the first to examine how it worked.

Willis was part of the remarkable generation of Britons who founded the Royal Society, aiming to understand the physical world: William Harvey, who by discovering the circulation of the blood had, as Willis said, created `a new foundation of medicine', Christopher Wren, Robert Hooke, Robert Boyle and William Petty, whom Karl Marx called the father of political economy.

To keep the Restoration Stuart state on side, they excluded from the Society the materialist Thomas Hobbes, who had said that the mind was `matter in motion'. As the Platonist Henry More realised, `No spirit, no God'.

Willis' book `The Anatomy of the Brain and Nerves' mapped the brain, and was the first unified treatment of the brain and the nerves. The new science combined anatomical study of the human brain with comparisons to animal brains, experiments and medical observations. He identified the loop of arteries that supplies the brain, which became known as the Circle of Willis. The 20th century neurologist Lord Brain described Willis as `the Harvey of the nervous system'.

Willis "created a material explanation of the soul and its disorders. ... He had transformed the traditional three-part soul, which had existed since Plato, into the corpuscular chemistry of the nervous system. The soul was not just moved to the brain but limited to it, and only through the nerves could it experience the world."

But the idealist philosopher John Locke attacked Willis' materialist approach, holding back neurology's development.
