The Living Force
On the scale of within the religion, you are right.I think you missed his point, which was that within religions, group cooperation was created.
When considering the scale bigger than one religion, and taking into account truth and lies, the 3 monotheistic religions are a scourge on mankind. And Haidt completely forecloses the possibility that religions based on truth are not fantasies but tap into a reality beyond mainstream science, because religion to him is the byproduct of agency detection gone wrong. Plus, false religions are not necessary for group cooperation, and his egalitarian pre-agriculture example demonstrates as much.It depends on the scale under consideration. Within these big religions, people cooperate under certain norms. Granted, they need to achieve this cohesiveness in a dialectic that exclude "the other" (misbeliever, pagan, etc.) but within the limit of said religions, people are driven to form a society.
