Views

Kātyāyana's views on the word-meaning connection tended towards naturalism. Kātyāyana believed, like Plato

Along with his mentor, Socrates, and his student, Aristotle, Plato helped to lay the...

, that the word-meaning relationship was not a result of human convention. For Kātyāyana, word-meaning relations were siddha, given to us, eternal. Though the object a word is referring to is non-eternal, the substance of its meaning, like a lump of gold used to make different ornaments, remains undestroyed, and is therefore permanent.

Realizing that each word represented a categorization, he came up with the following conundrum (following Matilal):
If the 'basis' for the use of the word 'cow' is cowhood (a universal) what would be the 'basis' for the use of the word 'cowhood'?

Clearly, this leads to infinite regress. Kātyāyana's solution to this was to restrict the universal category to that of the word itself — the basis for the use of any word is to be the very same word-universal itself.

This view may have been the nucleus of the Sphoṭa doctrine enunciated by Bhartṛhari in the 5th c., in which he elaborates
the word-universal as the superposition of two structures — the meaning-universal or the semantic structure (artha-jāti)
is superposed on the sound-universal or the phonological structure (śabda-jāti).
