10: The difference between faith and knowledge may stem just from a person's perspective on the situation.
13: Religious teachings about the origins of things are in general simple. The difficulty comes in when the religious entities disrupt the normal flow of things.
14: Religious explanations often produce more complexity then simplification.
17: Inference systems are used by religion to help make self-evident logic conclusions about certain events.
37: Comparisons between human cultures stem primarily from politics.
57: All religions are created using combinations of the same core concepts, each is just combined and localized differently.
73: Many religious stories are based on the idea of taking a concept and creating a counterintuitive element that makes it stick out.
76: Concepts such as UFOs and alien abductions continue to exist (despite a lack of scientific evidence) because people want to believe that there is something else.
78-79: The concept of mental templates (animal, person, tool) that the brain manages plays into how they are challenged in religion (i.e. a god is a person that doesn't grow old and die but can still affect you).
112: You learn a lot only if you are selective. Filter to learn.
156: Supernatural agents are presumed to have full access to strategic information versus the limited knowledge a human in the same scenario would have.
197: People are interested in particulars not generalities. They want to know how the situation affected them or ask a question like "Why me?"
237: Rituals are organized to make the inclusion/effect of a supernatural agent plausible.
250: Today's social environment is build on various levels of trust. Instead of just the small band of hunter-gatherers that you lived with the modern urban society requires dependence on vast numbers of other people for almost every aspect of daily life.
261: One-shot events are usually loud and the gods themselves act (marriage). Repeated rituals are usually somber events that have the gods acted upon (communion).
282: People will always distort religious doctrine to make it their own. Likewise organized religions (which usually wield some form of political power) will continue to try and control the practiced doctrine of their religion.
288: Humans have a propensity towards groups, always trying to join and demonstrate loyalty to a group or groups (family being the most basic).
300-301: The following all contribute to lead us away from clear and supported beliefs: consensus effect, false consensus effect, generation effect, memory illusions, source monitoring defects, confirmation bias, and cognitive dissonance reduction.
325: We only accept religious beliefs that jointly activate inference systems for agency, predation, death, morality, social exchange, etc.

If you are looking for a quick introduction into the concepts covered in the first few chapters I'd suggest looking at the summary charts on pages 18, 22, 27, 31, 106, 115, 128, and 135. I think looking them over ahead of time will help put the preceding discussions in a better light.
