A dealbreaker, in the sense developed in this essay, is a relationship between a person's psychology and an aspect of an artwork to which they are exposed. When a person has a dealbreaking aversion to an aspect of a work, they are blocked from embracing the work's aesthetically positive features. I characterize dealbreakers, distinguish this response from other negative responses to an artwork, and argue that the presence or absence of a dealbreaker is in some cases an appropriate target of (...) moral evaluation. I then use the concept of dealbreakers to develop a new approach to the question of our moral obligations with respect to the work of immoral artists, arguing that there is no general obligation binding us to cultivate or eliminate a dealbreaking aversion to their work. I conclude by suggesting several other philosophical debates that could benefit from a focus on dealbreakers. (shrink)
