Dear Reader—

I have been waiting for more than a decade to write Waking Up. Long before I saw any reason to criticize religion (The End of Faith, Letter to a Christian Nation), or to connect moral and scientific truths (The Moral Landscape, Free Will, Lying), I was interested in the nature of human consciousness and the possibility of “spiritual” experience. In Waking Up, I do my best to show that a certain form of spirituality is integral to understanding the nature of our minds.

There is no discrete self or ego living like a minotaur in the labyrinth of the brain. And the feeling that there is—the sense of being perched somewhere behind your eyes, looking out at a world that is separate from yourself—can be altered or entirely extinguished. Although such experiences of “self-transcendence” are generally thought about in religious terms, there is nothing, in principle, irrational about them. From both a scientific and a philosophical point of view, they represent a clearer understanding of the way things are.

My hope is that Waking Up will help readers see the nature of their own minds in a new light. A rational approach to spirituality seems to be what is missing from secularism and from the lives of most of the people I meet. The purpose of this book is to offer readers a clear view of the problem, along with some tools to help them solve it for themselves.

I sincerely hope you find it useful.

Sam Harris
