INDIAN LOGIC
categories posited by the Nyāya-Vaiseșika authors this hypothesis was logically self-consistent, but that was its almost sole merit. For otherwise it is plainly impossible to give it any sensible meaning whatsoever. In working out the details of this hypothesis the NyāyaVaiseșika authors were considerably guided by the analogy of mental states like cognition, pleasure, pain, desire, aversion etc. supposed to be produced in an eternal ubiquitous soul in the form of a momentary quality. But the very fact that the phenomenon of a sound and the phenomenon of a mental state are so much unlike each other precluded the possibility of any material light being thrown on the nature of one as a result of comprehending the nature of the other. .
Here ends Jayanta's enquiry into the question whether or not a word is an eternal verity, and with it his Ahnika III.
