Book excerpt: The brain, with its nearly one hundred billion neurons, is the most complex structure in the universe, and we are living in a period of revolutionary advancements in neuroscience. Yet scientists and skeptics often frame these findings in ways that challenge the Christian worldview. Many professionals and popularizers claim that human beings are their brains, and that all human behavior and experience are merely by-products of brain physiology. In The Brain, the Mind, and the Person Within, professor of psychology Mark Cosgrove not only explains what the brain is and what it does but also corrects common misinterpretations and demonstrates that what we know about the brain coheres with the teachings of Scripture. He contends that humans are unities of soul and body in which both the spiritual and the physical interact. From this perspective, he presents informative overviews of contemporary debates about the brain, including consciousness, free will, "God spots," personhood, and life after death. The better we understand the brain, the better we understand ourselves and our exquisite design that reflects the wisdom of the Creator. Thoughtful readers will find this to be a fascinating, accessible survey of this unique part of the body and the profound theological and technological issues surrounding it.
