What is Deontology/Utilitarianism

This chapter investigates if System 2 (analytic system) can revise or suppress the negative outputs of System 1 (intuitive system) by natural experiment in history. Two periods are picked up in this chapter: the 17th century when there was a decline in war, torture, cruel punishment, and religious persecution, and the time after World War II when there has been a decline in war, genocide, and violence with growing awareness of human rights. In short, the outputs associated with strong emotion are less likely to be revised, and an effective way for revision is to use a story to trigger the theory of mind in System 1. This is also discussed in the frame of distinction between deontic moral judgment and utilitarian moral judgment. Finally, it is proposed that a good story should be elaborated by System 2 and be prevailed so that it arises emotions (sympathy) of System 1 and drives people for the better-being future.
