Penetrating observations and speculations for scientifically inclined readers.
The renowned neuroscientist delivers a short but definitely not superficial investigation of consciousness, widely but wrongly looked on as mysterious.
Damasio—the chair of neuroscience and professor of psychology, neurology, and philosophy at USC, where he heads the Brain and Creativity Institute—emphasizes that he has no patience with efforts to solve the “hard problem”—i.e., explaining how the mass of neurons in the physical brain generates conscious mental states. His reason: They don’t, at least not by themselves. While the brain plays an indispensable role, it requires input from “non-neural tissues of the organism’s body proper.” At the simplest level, our physical senses provide feelings, and our memory provides context that our sense of self integrates into what we experience as consciousness, which the author defines as “a particular state of mind resulting from a biological process toward which multiple mental events make a contribution,” Feelings, writes Damasio, “provide the mind with facts on the basis of which we know, effortlessly, that whatever else is in the mind, at the moment, also belongs to us. Feelings allow us to experience and become conscious. Homeostatic feelings are the first enablers of consciousness.” Refreshingly for a professor of neuroscience, Damasio writes lucid prose clearly addressed to a popular audience. Even better, the book is concise (180 pages of main text plus notes and references) and helpfully divided into dozens of short chapters—e.g., “The Embarrassment of Viruses,” “Nervous Systems as Afterthoughts of Nature,” “Turning Neural Activity Into Movement and Mind,” “Algorithms in the Kitchen”—many only one or two pages. Make no mistake, however; Damasio is a deep thinker familiar with multiple disciplines, and this is as much a work of philosophy as hard science. Readers familiar with college level psychology and neuroscience will discover rewarding insights, many of which the author covered in his last book, The Strange Order of Things (2018).

Some of Avant’s mantras are overstated, but her book is magnanimous, inspiring, and relentlessly optimistic.
Memories and life lessons inspired by the author’s mother, who was murdered in 2021.
“Neither my mother nor I knew that her last text to me would be the words ‘Think you’ll be happy,’ ” Avant writes, "but it is fitting that she left me with a mantra for resiliency.” The author, a filmmaker and former U.S. Ambassador to the Bahamas, begins her first book on the night she learned her mother, Jacqueline Avant, had been fatally shot during a home invasion. “One of my first thoughts,” she writes, “was, ‘Oh God, please don’t let me hate this man. Give me the strength not to hate him.’ ” Daughter of Clarence Avant, known as the “Black Godfather” due to his work as a pioneering music executive, the author describes growing up “in a house that had a revolving door of famous people,” from Ella Fitzgerald to Muhammad Ali. “I don’t take for granted anything I have achieved in my life as a Black American woman,” writes Avant. “And I recognize my unique upbringing…..I was taught to honor our past and pay forward our fruits.” The book, which is occasionally repetitive, includes tributes to her mother from figures like Oprah Winfrey and Bill Clinton, but the narrative core is the author’s direct, faith-based, unwaveringly positive messages to readers—e.g., “I don’t want to carry the sadness and anger I have toward the man who did this to my mother…so I’m worshiping God amid the worst storm imaginable”; "Success and feeling good are contagious. I’m all about positive contagious vibrations!” Avant frequently quotes Bible verses, and the bulk of the text reflects the spirit of her daily prayer “that everything is in divine order.” Imploring readers to practice proactive behavior, she writes, “We have to always find the blessing, to be the blessing.”

An enthusiastic appreciation of a spectacular astrophysical entity.
A short, lively account of one of the oddest and most intriguing topics in astrophysics.
Levin, a Guggenheim fellow and professor of physics and astronomy at Barnard College, knows her subject well, but her goal is appreciation as much as education, and there is much to admire in a black hole. Before Einstein, writes the author, scientists believed that the force of gravity influenced the speed of moving objects. They also knew that light always travels at exactly the speed of light. This combination made no sense until 1915, when Einstein explained that gravity is not a force but a curving of space (really, space-time) near a body of matter. The more massive the matter, the greater it curves the space in its vicinity; other bodies that approach appear to bend or change speed when they are merely moving forward through distorted space-time. Einstein’s equations indicated that, above a certain mass, space-time would curve enough to double back on itself and disappear, but this was considered a mathematical curiosity until the 1960s, when objects that did just that began turning up: black holes. Light cannot emerge from a black hole, but it is not invisible. Large holes attract crowds of orbiting stars whose density produces frictional heating and intense radiation. No writer, Levin included, can contain their fascination with the event horizon, the boundary of the black hole where space-time doubles back. Nothing inside the event horizon, matter or radiation, can leave, and anything that enters is lost forever. Time slows near the horizon and then stops. The author’s discussions of the science behind her subject will enlighten those who have read similar books, perhaps the best being Marcia Bartusiak’s Black Hole (2015). Readers coming to black holes for the first time will share Levin’s wonder but may struggle with some of her explanations.
