For the millions of people who want spirituality without religion, Sam Harris's new book is a guide to meditation as a rational spiritual practice informed by neuroscience and psychology. Throughout the book, Harris argues that there are important truths to be found in the experience of contemplatives such as Jesus, Buddha and other saints and sages of history-and, therefore, that there is more to understanding reality than science and secular culture generally allow. Waking Up is part seeker's memoir and part exploration of the scientific underpinnings of spirituality. No other book marries contemplative wisdom and modern science in this way, and no author other than Sam Harris-a scientist, philosopher, and famous sceptic-could write it.
