The relationships (dependencies, perhaps) of all the senses seem to be suggested as any questions are asked as to the true nature of thought(crossthreading-e)... as each of us show more or less development through nurture. My hearing makes me focus just as my sight makes me hear or listen for. Certainly a clearer, possibly more direct connection with language that sights and sounds offer is manifest through humor.
