“When people see themselves in zero-sum relationship with other people — see their fortunes as inversely correlated with the fortunes of other people, see the dynamic as win-lose — they tend to find a scriptural basis for intolerance or belligerence...When they see the relationship as non-zero-sum — see their fortunes as positively correlated, see the potential for a win-win outcome — they’re more likely to find the tolerant and understanding side of their scriptures.”

- Robert Wright, The Evolution of God
