The better we understand human psychology and neurology, the more we will uncover the underpinnings of religion. Some of them, like the attachment system, push us toward a belief in gods and make departing from it extraordinarily difficult. But it is possible.
We can be better as a species if we recognize religion as a man-made construct. We owe it to ourselves to at least consider the real roots of religious belief, so we can deal with life as it is, taking advantage of perhaps our mind’s greatest adaptation: our ability to use reason.
