On the Match by Closeness Approach to Limited Aggregation

In a recent article in this journal, James Hart argues against a dilemma posed by Joe Horton to views of limited aggregation. Hart argues that one horn is fatal but avoidable while the other horn is neither fatal nor avoidable. Moreover, he presents a principle of limited aggregation—Match by Closeness—that supposedly avoids the fatal horn. However, as I show in this article, Match by Closeness does not avoid the fatal horn.
