Overview
Consciousness is our gateway to experience: it enables us to recognize Van Gogh’s starry skies, be enraptured by Beethoven’s Fifth, and stand in awe of a snowcapped mountain. Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science.
In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and builds on the latest research to propose a new model for how consciousness works. Bor argues that this brain-based faculty evolved as an accelerated knowledge gathering tool. Consciousness is effectively an idea factory—that choice mental space dedicated to innovation, a key component of which is the discovery of deep structures within the contents of our awareness.
This model explains our brains’ ravenous appetite for information—and in particular, its constant search for patterns. Why, for instance, after all our physical needs have been met, do we recreationally solve crossword or Sudoku puzzles? Such behavior may appear biologically wasteful, but, according to Bor, this search for structure can yield immense evolutionary benefits—it led our ancestors to discover fire and farming, pushed modern society to forge ahead in science and technology, and guides each one of us to understand and control the world around us. But the sheer innovative power of human consciousness carries with it the heavy cost of mental fragility. Bor discusses the medical implications of his theory of consciousness, and what it means for the origins and treatment of psychiatric ailments, including attention-deficit disorder, schizophrenia, manic depression, and autism. All mental illnesses, he argues, can be reformulated as disorders of consciousness—a perspective that opens up new avenues of treatment for alleviating mental suffering.
A controversial view of consciousness, The Ravenous Brain links cognition to creativity in an ingenious solution to one of science’s biggest mysteries.

Human consciousness, as described by Bor, a neuroscientist and research fellow at the University of Sussex, is an evolutionary outgrowth of the brain’s search for information and uncovering patterns in the world around us. He argues compellingly that this confers an evolutionary advantage and that “it evolved, like almost everything else in nature, in an incremental way.”He goes on to explain the mechanisms the brain uses to increase its efficacy at this task, focusing most on the concept of chunking, or finding ways to bring coherence to a large amount of data. Though others have capably presented the relationship between brain and mind, and the functions of various portions of the brain, Bor does it so effectively that the material remains fresh.He explores how our brains differ both from computer programs and from other animals (such as apes, crows, and octopi) that are also self-aware. “Perhaps what most distinguishes us humans from the rest of the animal kingdom is our ravenous desire to find structure in the information we pick up in the world.” Bor balances neuroscience with comparative biology, and philosophy with psychology while writing in a fully engaging conversational style.

From a cognitive neuroscientist, a lively look at what research is revealing about consciousness and a view of some of the ethical implications of recent findings about the brain's "ravenous appetite for wisdom." Bor (Research Fellow/Univ. of Sussex, Sackler Centre for Consciousness Science) asserts that centuries of philosophical arguments about consciousness have shed little light on the subject and that the science of consciousness, now some two decades old, has much to tell us. Descartes receives special scrutiny. After an opening chapter dismissing many philosophical debates, Bor turns to the evolutionary background of consciousness, which he describes as a certain kind of processing of information that captures useful patterns in the environment. His experience of being under general anesthesia for surgery introduces a discussion of the boundary between consciousness and unconsciousness. He distinguishes between conscious and unconscious processes, examines the psychology and neurophysiology of awareness, and explains how our brains utilize a process called chunking to organize pieces of information into meaningful groups. Bor also takes up the question of how to assess consciousness in various species of animals and in mute individuals who have suffered traumatic brain injuries, and he explores the relationship of dysfunctional consciousness in autism, schizophrenia, ADHD and other mental disorders. Finally, the author includes a cautionary note about the fragility of the human mind; in his view, adopting an attitude of skepticism and practicing meditation are beneficial. Bor keeps general readers in mind, making challenging subject matter entertaining by peppering his narrative with personal anecdotes, imaginative thought experiments and probing research studies. An enthusiastic report from the front lines of cognitive science designed to pique the interest of nonscientists.Product Details
