 Śrīharṣa’s main objection against this definition of aboutness involves a threat of idealism (vijñānavāda) (KKh 650ff). He points out that the property of being-of-that-ness that Udayana speaks of is decomposable into two elements: the part picked out by the expression ‘that’, namely the object of awareness o, and the part picked out by “being of”, which corresponds to the relation R by which the awareness-episode is related to the object. If both these elements are part of the nature of the awareness-episode—the definition claims—then the object o wouldn’t be external to the awareness-episode e. The Nyāya-Vaiśeṣika view, therefore, would collapse into idealism!
