Infected by evil

In this paper I argue that there is good reason to believe that we can be influenced by fictions in ways that matter morally, and some of the time we will be unaware that we have been so influenced. These arguments fall short of proving a clear causal link between fictions and specific changes in the audience, but they do reveal rather interesting and complex features of the moral psychology of fiction. In particular, they reveal that some Platonic worries about the dangers of art cannot be dismissed lightly.
