Religion Explained
May 2001, Random House (UK) and Basic Books (USA).

(review)
The main theme of this book is that we now have a better understanding of religious representations, their causes and their role in human cognition, simply because we have a better and more precise understanding of the mind-brain, its evolution, its structure and its specific dispositions.
To understand religion, it may be a good thing to know what it is. (It is striking how few discussions of religion actually follow that principle). For example, most religion in the world is not about God, bot about immortality, and not about being rewarded for being good. The religions we are familiar with are only a small selection in a larger repertoire of supernatural ideas.
People do not have religion because there is a specific need for it, or a special part of the brain that creates religion. Religious ideas and norms happen to be highly "contagious" given the kinds of brains we humans have. You cannot hope to understand religion if you do not understand what is happening in the "mental basement": that is, in all sorts of cognitive processes that our conscious inspection cannot reach.
