Abstract
In this article, following a trajectory set out by Noël Carroll, Matt Hills, and Andrea Sauchelli, I propose a definition of horror, according to which something qualifies as a work of horror if and only if it centrally and demonstrably aims at provoking one or more of a particular set of negative affects. A catalog of characteristically negative affects is associated with horror—including terror, revulsion, the uncanny, and the abject—but which cannot be collapsed into any single affect. Further complicating matters is that the set appears to be constantly, if slowly, mutating, so that the affects aimed at in the horror of the 1920s do not entirely overlap with those aimed at horror today, or which we might expect horror to aim at a century from now. As such, while we use “horror” as a blanket term across eras, whether some work is a work of horror will always be time-indexed.
