How Can the Word “Cow” Exclude Non-cows? Description of Meaning in Dignāga’s Theory of Apoha

Abstract

Dignāga's theory of semantics called the "theory of apoha (exclusion)" has been criticized by those who state that it may lead to a circular argument wherein "exclusion of others" (anyāpoha) is understood as mere double negation. Dignāga, however, does not intend mere double negation by anyāpoha. In his view, the word "cow" for instance, excludes those that do not have the set of features such as a dewlap, horns, and so on, by applying the semantic method called componential analysis. The present paper aims to prove this by referring to the fragments quoted by Jinendrabuddhi and Siddhasenagaṇi. Dignāga logically proves that the denotation of the referent Q by the word "P" cannot be derived from the joint presence (anvaya) of "P" with Q. Instead, he derives it from the joint absence (vyatireka) of "P" with the nonexistence of Q. Anyāpoha is nothing but verbal vyatireka. Componential analysis is used for describing what is to be excluded. Dignāga draws taxonomic hierarchies of words based on their customary use, and assumes componential analysis to operate in the background of the hierarchies formed in semantic fields, stating that a general term is restricted to having the same reference with one of its specific terms insofar as the former is connected (yukta) with the characteristics of the latter's referent. Moreover, he states that a proper name also denotes its referent by excluding those that do not have the cluster of a certain number of qualities.
