Abstract
Are there any facts that call for explanation? According to one possible view, all facts call for explanation; according to another, none do. This paper is concerned with an intermediate view according to which some facts call for explanation and others do not. Such a view requires explaining what makes some facts call for explanation and not others. In this paper, I explore a neglected proposal, inspired by the work of George Schlesinger, according to which facts call for explanation when they belong to extraordinary types. I compare the merits of this view to those of several alternatives and respond to a salient objection. I end with a discussion of how the theory fares when applied to cosmological fine-tuning arguments.
