The Belief Instinct: The Psychology of Souls, Destiny, and the Meaning of Life Bering, J. W. W. Norton & Company (February 7, 2011)
Bering lays out a clear and cogent argument for our (homo sapiens) need to believe. To believe in spirits, to believe in God, to believe in an afterlife, all as a consequence of our ability to think that others think.
He is a deft story teller, but the book is backed with references to a long list of thinkers and experimentalists, and has me searching for original writings from Sartre, James, Dennet, and many others.
As a humanist, I found this book a refreshing affirmation that I am a human, I have tendencies that have been sculpted and molded over millenia, and understanding those, I have an opportunity to make choices now.
Read it, and enjoy being human!
