Abstract. Batterman has recently argued that fundamental theories are typically explanatorily inadequate, in that there exist physical phenomena whose explanation requires that the conceptual apparatus of a fundamental theory be supplemented by that of a less fundamental theory. This paper is an extended critical commentary on that argument: situating its importance, describing its structure, and developing a line of objection to it. The objection is that in the examples Batterman considers, the mathematics of the less fundamental theory is definable in terms of the mathematics of the fundamental theory, and that only the latter need be given a physical interpretation—so we can view the desired explanation as drawing only upon resources internal to the more fundamental physical theory.

Notes. (1) This paper discusses Bob Batterman's book The Devil in the Details. Batterman has a response. (2) The preprint linked to above contains an appendix on quantum chaos omitted from the published version.
