The Coherent and the Rational
This chapter motivates Reasons Responsiveness by situating it within the metaethical literature on rationality. The first task is to show how Reasons Responsiveness can overcome prominent arguments given by John Broome that seek to show that rationality is not a function of normative reasons. The second task is to show that Reasons Responsiveness can capture the data that motivates rival coherentist accounts in the metaethical literature. It is argued that usually one is irrational when incoherent and that Reasons Responsiveness can explain this because of the way in which reasons transmit. Some forms of incoherence are not irrational. Reasons Responsiveness can explain this as well. The upshot is that Reasons Responsiveness can explain the data that motivates rival views without incurring their main problems.
