This paper aims to precisely characterize the theoretical significance of the notion of truthmakers. First, the closeness of the alleged principle of truthmaker theory and the realistic intuition on which it rests is assessed, thereby determining to what extent a certain kind of general objection against truthmaker theory carries weight. Second, the principle of truthmaker theory is reformulated on the basis of this assessment, and truthmaker theory is argued to offer a methodological role for identifying fundamental entities that ground metaphysically nonfundamental truths. The discussion suggests a sophisticated nonQuinean criterion of ontological commitment.
