The objective of this work is to try to carve out the rational dynamics of the attitude of acceptance. Building on Laura Soter’s work on acceptance, which advocates that moralists of belief should moralize acceptance instead of belief, I motivate the needs of evidential norms that govern acceptance, and propose a theory sketch about what evidential norms of acceptance there are. I design a series of cases in which the agent fails to meet the moral aim by not paying due respect to evidence, and draw different evidential norms from these cases.
