 For a justification of the success of language, antirealists can appeal to the theory of apoha and the explanation involving causality in concept formation. Indeed, words reflect conceptual distinctions that can also be understood as constructed universals; language can only occur within a system of concepts. In Dharmakīrti’s system, which is here presupposed, words are associated via conventions not with an object, but with a “distinction” which requires a bipartition of particulars in two complementary domains. A word can be associated to this distinction of xs from non-xs at the time of an agreement. Subsequently, any use of an utterance that is a token of this word indicates nothing else than the elimination of non-xs, but can lead to obtain a particular excluded from non-xs. The causal process involved in the process of concept formation is what ensures success, provided that conventions are established and learned successfully.
