Humans are, by nature, pattern-seeking, storytelling animals, and we are quite adept at telling stories about patterns whether they exist or not.

Perceiving the world as well designed and thus the product of a designer, and even seeing divine providence in the daily affairs of life, may be the product of a brain adapted to finding patterns in nature. (38)

How can we find spiritual meaning in a scientific worldview? Spirituality is a way of being in the world, a sense of one’s place in the cosmos, a relationship to that which extends beyond oneself. . . . Does scientific explanation of the world diminish its spiritual beauty? I think not. Science and spirituality are complementary, not conflicting; additive, not detractive. Anything that generates a sense of awe may be a source of spirituality. Science does this in spades. (158-159)

There is a significant difference between having no belief in a God and believing there is no God.

In the past 10,000 years, humans have devised roughly 100,000 religions based on roughly 2,500 gods. So the only difference between myself and the believers is that I am skeptical of 2,500 gods whereas they are skeptical of 2,499 gods. We're only one God away from total agreement.

There are many sources of spirituality; religion may be the most common, but it is by no means the only. Anything that generates a sense of awe may be a source of spirituality. Science does this in spades.

People have a hard time accepting free-market economics for the same reason they have a hard time accepting evolution: it is counterintuitive. Life looks intelligently designed, so our natural inclination is to infer that there must be an intelligent designer--a God. Similarly, the economy looks designed, so our natural inclination is to infer that we need a designer--a government. In fact, emergence and complexity theory explains how the principles of self-organization and emergence cause complex systems to arise from simple systems without a top-down designer.
