Abstract
This chapter discusses how we should think about experiences that threaten to radically transform our understanding of the world. While it can be rational to treat the “doxastically transformative” potential of an experience as a reason to choose against it, such a decision must be based in something more than the fact that this experience would alter one’s current beliefs. It only in light of knowledge of how things are that a person can choose rationally against transformative processes that would destroy this knowledge.
