 Many recent approaches define truth-making in terms of grounding or what is sometimes described as non-causal metaphysical dependence. The notion of truth-making is typically introduced, as we have seen, in terms of the ideology of “in virtue of”. As we have also seen, many philosophers then ask: but what independent content can be given to this notion? In response to this challenge, a theory of grounding may be conceived as a general theory of “in virtue of” in terms of which truth-making may then be explained. A further consideration which motivates those already committed to grounding is the general methodological principle that favours theoretical unification. Their idea is that by conceiving of truth-making as a kind of grounding, we are able to understand truth-making better, i.e. not as an isolated phenomenon but as an instance of a more general pattern, thereby illuminating not only the nature of truth-making but grounding too.
