Patricia Churchland is the author of, most recently, Conscience: The Origins of Moral Intuition and Touching a Nerve: Our Brains, Our Selves. She is professor emerita of philosophy at the University of California, San Diego, and the recipient of a MacArthur Fellowship. She lives in San Diego.

“A thoughtful, accessible, and enlightening book.”

- Kirkus Reviews

“Conscience is an entertaining, erudite, and timely reminder of the neurobiological origins of those voices in our head telling us to behave. Moral philosophers, zealots and ideologues have been arguing for their versions of ‘good’ and ‘bad’ for millennia; now it’s time for Patricia S. Churchland to remind us that morality doesn’t come from a stone tablet or a logical axiom, but is rather one of Nature’s inventions enabling our greatest superpower: sociality. It’s messy, useful, and very human―like thumbs.”

- Blaise Agüera y Arcas, distinguished scientist, Google AI

“Patricia S. Churchland takes us on a fascinating journey intertwining philosophy from Socrates and Aristotle to Kant and Solzhenitsyn to the latest ideas in neuroscience, covering a vast span of knowledge in a graceful and appealing style that is spellbinding. A jewel among books about human nature.”

- Ann Graybiel, investigator at the McGovern Institute for Brain Research at MIT

“In Conscience, Patricia S. Churchland pulls back the curtains and takes us behind the scenes to show where our morals come from. Packed with the latest neuroscience research, the surprising answer turns out to be our very own brains. A must-read for anyone with a conscience.”

- Gregory Berns, author of How Dogs Love Us

“Patricia S. Churchland has done it again! She wisely guides readers on a lively romp through recent research in neuroscience, genetics, evolution, psychology, psychiatry, anthropology, economics, politics, and philosophy in order to reach a more complete understanding of how and why we can get along despite our deep disagreements about what is wrong or right. This fun and fascinating journey shows why morality cannot be fully understood without the wide variety of perspectives and of scientific information that this tour de force provides.”

- Walter Sinnott-Armstrong, author of Think Again

“No one blends philosophy and neuroscience as well as Patricia S. Churchland. Here she provides a much-needed correction to the usual emphasis on reasoning and logic in moral philosophy. Our judgements are guided by ancient intuitions and brain processes shared with other mammals.”

- Frans de Waal, author of Mama’s Last Hug

“The British intellectual C.P. Snow gave a lecture in which he argued that the sciences and humanities were different enterprises that could never be bridged. Churchland’s pioneering book Neurophilosophy showed that the bridge is in fact the human brain. Now she tackles the last stronghold of orthodox philosophers―human morality itself. And she has done it again, providing a powerful argument for a neuroscientific approach to morality”
