Abstract

The purpose of this paper is to clarify the connection between two notions of growing interest in contemporary metaphysics – truthmaking and grounding. The former has provoked a great deal of controversy since the 1980s, whereas the latter has attracted serious attention only since the beginning of this century. Although the two notions are closely connected, only a few attempts have been made so far at clarifying that connection. The present paper is intended as an investigation of the connection on the basis of the appreciation of the core ideas of truthmaker theory. To begin with, two conceptions of the connection are distinguished, and the conception that truthmaking can be defined in terms of grounding is endorsed. Next, two ideas that form the core of truthmaker theory are delineated, and it is argued that the definition of truthmaking should be based on the idea that truthmakers are metaphysically fundamental entities. Finally, it is shown that a particular problem with grounding can be resolved by restricting a relevant logical principle for grounding, justified by the idea that truth is a derivative aspect of reality. The discussion reveals the significance of appreciating the core of truthmaker theory in developing a theory of grounding.
