  All seeings are the product of a sensory connection (of a type to be specified) with the thing seen. This basic idea must be embellished in two ways before it is can serve as a proper a theory of perception: (i) some account must be given of the fact that, in all the cases cited above, the content of perception is semantically structured (e.g. that the thing in the corner is a piece of rope), for otherwise perceptual experiences would not be capable of being true, and hence fail to qualify as knowledge-episodes; (ii) an account must be given of the type of ‘connection’ involved here. Only then can we evaluate the merits of the Nyāya theory.
