 Then, the question will be: How do we determine whether an awareness-episode is an instance of knowledgehood? Even when the awareness-episode is our own, we cannot ascertain whether it is knowledge by introspection alone; for, even though we may be aware of an awareness-episode by introspection, we could still doubt or be mistaken as to whether it is knowledge. So, it seems that we can only determine whether an awareness-episode constitutes knowledge by means of inference on the basis of some kind of symptom. Are there many such symptoms or one? If there is just one symptom distinct from knowledgehood, we should just treat that as the defining property of knowledge; so, defining knowledge in terms of knowledgehood makes no sense. But if there are many such symptoms, we need to say which ones they are; for Śrīharṣa has already argued that the widely accepted definitions of knowledge are inadequate and therefore cannot be reliable symptoms of knowledge.
