Review by Booklist Review

Pioneering scientist Damasio, like Crick (see above), has some illuminating things to say about the interconnectedness of mind and body and the workings of the brain. He relates a number of revealing case studies involving brain damage that illustrate his central theme: that emotions are essential to our ability to reason and make decisions.

Review by Publisher's Weekly Review

In an important, gracefully written exploration of the neurochemical basis of mind, neurologist Damasio rejects the Cartesian notion of the human mind as a thinking organ more or less separate from bodily processes. Emotions and feelings, he argues, are essential to reasoning and decision-making. The human brain, he further contends, has a specialized region in the frontal lobes for making personal and social decisions, and this region works in concert with deeper brain centers that store emotional memories. To support this controversial claim, Damasio draws on his work with brain-injured patients at the University of Iowa College of Medicine, and also cites the case of Phineas Gage, a Vermont railway foreman who lost his ethical faculties after an explosion in 1848 drove a metal rod through his skull. Damasio's exciting investigation challenges the fashionable metaphor of the mind as a software program.

Review by Library Journal Review

The idea that the mind exists as a distinct entity from the body has profoundly influenced Western culture since Descartes proclaimed, "I think, therefore I am." Damasio, head of neurology at the University of Iowa and a prominent researcher on human brain function, challenges this premise in a fascinating and well-reasoned argument on the central role that emotion and feelings play in human rationality. According to Damasio, the same brain structures regulate both human biology and behavior and are indispensable to normal cognitive processes. Damasio demonstrates how patients (his own as well as the 19th-century railroad worker Nicholas Gage) with prefrontal cortical damage can no longer generate the emotions necessary for effective decision-making. A gifted scientist and writer, Damasio combines an Oliver Sack-like reportage with the presentation of complex, theoretical issues in neurobiology.

Review by Kirkus Book Review

Few neuroscientists today would defend Cartesian dualism--the idea that mind and body are separate--but Damasio takes one more leap: Not only are philosophers wrong to separate brain and body, but psychology's separation of reason from emotion is also wrong. Most neuroscientists agree that what we call the mind reflects the functions of the nervous system--in short, crudely speaking, the body. Modern science, however, has transferred the old mind- body split into a brain-body dichotomy in which the brain occupies a hierarchically privileged place. But Damasio (Neurology/Univ. of Iowa College of Medicine) democratizes the relationship between brain and body; he posits a powerful interdependence in which our physical experience of the world around us is central to the creation of our sense of self, and colors our behavior. His persuasive argument begins with Phineas Gage, a 19th-century railway worker who suffered brain damage when an iron rod shot through his head like a missile, destroying his left eye and parts of his frontal lobes. The result was not a loss of speech or memory but profound personality and emotional changes and an inability to make rational judgments about the present and future. Damasio and his wife, Hanna, have studied patients with similar frontal-lobe damage and similar effects: IQ, memory, and language are intact, but there is a lack of feeling and an inability to put current events in context and make future judgments. These points are eloquently expressed, along with the anatomical/physiological evidence linking the frontal cortices with sensory-motor areas and emotional networks that feed forward and backward from the body surface and internal organs. Damasio is the first to admit that he cannot prove all he says. In the meantime, one can read with pleasure and share the excitement of a neuroscientist who sees that in the union of the many parts of the human brain lies its strength.

Chapter One: Unpleasantness in Vermont Phineas P. Gage It is the summer of 1848. We are in New England. Phineas P Gage, twenty-five years old, construction foreman, is about to go from riches to rags. A century and a half later his downfall will still be quite meaningful. Gage works for the Rutland & Burlington Railroad and is in charge of a large group of men, a "gang" as it is called, whose job it is to lay down the new tracks for the railroad's expansion across Vermont. Over the past two weeks the men have worked their way slowly toward the town of Cavendish; they are now at a bank of the Black River. The assignment is anything but easy because of the outcrops of hard rock. Rather than twist and turn the tracks around every escarpment, the strategy is to blast the stone and make way for a straighter and more level path. Gage oversees these tasks and is equal to them in every way. He is five-foot-six and athletic, and his movements are swift and precise. He looks like a young Jimmy Cagney, a Yankee Doodle dandy dancing his tap shoes over ties and tracks, moving with vigor and grace. In the eyes of his bosses, however, Gage is more than just another able body. They say he is "the most efficient and capable" man in their employ.- This is a good thing, because the job takes as much physical prowess as keen concentration, especially when it comes to preparing the detonations. Several steps have to be followed, in orderly fashion. First, a hole must be drilled in the rock. After it is filled about halfway with explosive powder, a fuse must be inserted, and the powder covered with sand. Then the sand must be "tampedin," or pounded with a careful sequence of strokes from an iron rod. Finally, the fuse must be lit. If all goes well, the powder will explode into the rock; the sand is essential, for without its protection the explosion would be directed away from the rock. The shape of the iron and the way it is played are also important. Gage, who has had an iron manufactured to his specifications, is a virtuoso of this thing. Now for what is going to happen. It is four-thirty on this hot afternoon. Gage has just put powder and fuse in a hole and told the man who is helping him to cover it with sand. Someone calls from behind, and Gage looks away, over his right shoulder, for only an instant. Distracted, and before his man has poured the sand in, Gage begins tamping the powder directly with the iron bar. In no time he strikes fire in the rock, and the charge blows upward in his face. The explosion is so brutal that the entire gang freezes on their feet. It takes a few seconds to piece together what is going on. The bang is unusual, and the rock is intact. Also unusual is the whistling sound, as of a rocket hurled at the sky. But this is more than fireworks. It is assault and battery. The iron enters Gage's left cheek, pierces the base of the skull, traverses the front of his brain, and exits at high speed through the top of the head. The rod has landed more than a hundred feet away, covered in blood and brains. Phineas Gage has been thrown to the ground. He is stunned, in the afternoon glow, silent but awake. So are we all, helpless spectators. "Horrible Accident" will be the predictable headline in the Boston Daily Courier and Daily Journal of September 20, a week later. "Wonderful Accident" will be the strange headline in the Vermont Mercury of September 22. "Passage of an Iron Rod Through the Head" will be the accurate headline in the Boston Medical and Surgical Journal . From the matter-of-factness with which they tell the story, one would think the writers were familiar with Edgar Allan Poe's accounts of the bizarre and the horrific. And perhaps they were, although this is not likely; Poe's gothic tales are not yet popular, and Poe himself will die the next year, unknown and impecunious. Perhaps the horrible is just in the air. Noting how surprised people were that Gage was not killed instantly, the Boston medical article documents that "immediately after the explosion the patient was thrown upon his back"; that shortly thereafter he exhibited "a few convulsive motions of the extremities," and "spoke in a few minutes"; that "his men (with whom he was a great favourite) took him in their arms and carried him to the road, only a few rods distant (a rod is equivalent to 5 1/2 yards, or 16 1/2 feet), and sat him into an ox cart, in which he rode, sitting erect, a full three quarters of a mile, to the hotel of Mr. Joseph Adams"; and that Gage "got out of the cart himself, with a little assistance from his men." Let me introduce Mr. Adams. He is the justice of the peace for Cavendish and the owner of the town's hotel and tavern. He is taller than Gage, twice as round, and as solicitous as his Falstaff shape suggests. He approaches Gage, and immediately has someone call for Dr. John Harlow, one of the town physicians. While they wait, I imagine, he says, "Come, come, Mr. Gage, what have we got here?" and, why not, "My, my, what troubles we've seen." He shakes his head in disbelief and leads Gage to the shady part of the hotel porch, which has been described as a "piazza." That makes it sound grand and spacious and open, and perhaps it is grand and spacious, but it is not open; it is just a porch. And there perhaps Mr. Adams is now giving Phineas Gage lemonade, or maybe cold cider. An hour has passed since the explosion. The sun is declining and the heat is more bearable.
