A scientist explains experiences that seem inexplicable.
Lightman, physicist, professor of the practice of humanities at MIT, and author of Einstein’s Dreams, is a materialist who believes that every phenomenon has a cause that originates in the physical universe. Even our feelings “are rooted in the material neurons of the nervous system and the electrical and chemical interactions between them.” Still, the author has also reveled in overwhelming feelings of awe, beauty, and a sense of connection with matters larger than himself, which he defines as “spirituality.” He denies that these can only be explained through mysterious occult forces. We experience them through the brain. This, he admits, puts him in the minority; 72% of Americans believe in heaven, 58% in hell, and nearly half in ghosts. Belief in a nonmaterial, ethereal world is deeply appealing because everyone knows that being alive is special and longs for permanence. No one can imagine not existing, and most of us are mesmerized by miracles; 79% of Americans believe in them. Never shy about tackling big, complex issues, Lightman devotes the first chapter to the soul: immaterial, invisible, and perfect in contrast to the flawed body. The soul is also eternal, and since most people believe that our selves don’t merely vanish when we die, even many nonreligious people believe in its existence. Lightman is skeptical, however. For most of the book, he argues that spiritual experiences emerge from a high level of consciousness and intelligence. One expert feels that consciousness is just another word for paying attention, which scientists are beginning to describe in terms of electrical and chemical activity in the brain. Lightman urges readers to accept a scientific view of the world while embracing experiences that cannot be understood by material underpinnings. We need to balance a yearning to know how the world works with a willingness to surrender ourselves to things we may not fully comprehend.
Convincing arguments for “spiritual materialism” unlikely to disturb religious readers.
