 Armed with these two sets of implication threads (and in this sense, different understandings of, or things we count as) sensation or feeling, it can be seen that perception requires neither of these. Seeing a cat does not require that I feel anything in the sense of pain, discomfort, tickle, giddiness, or calm (nor, we can add, relief, amusement, surprise, or rapture). Nor, however, does seeing a cat or hearing a violin require that I tactually or kinaesthetically feel with my eye or with my ear that which I also perceive. Nor does smelling require that I feel, in this sense, with my nose. And though the tongue is a double-sense organ insofar as I can tactually and kinaesthetically detect the texture and the temperature of food in my mouth, as well as taste it, tasting food does not depend upon my being able to feel these other properties of the food with my tongue.
