Cross-modal comparisons and a sense of self
“[The self is a substance] because a single object is grasped by touch and sight. [If you say] 'no, for there is restriction [of each sense] to its proper object', [we reply] this is not a refutation, because the existence of the self follows too from that very restriction” (Nyāyasūtra III.1.1–3).
“One must conceive of oneself as the numerically identical owner of one's experiences if one is capable of cross-modal comparisons. That conclusion is in agreement with recent work in developmental psychology claiming to show that an infant's cross-modal capacities are essentially implicated in their development of a sense of self.”
