Consciousness is not physically identical with the nervous system: it is "out there" with the cow, all throughout the field of sight (and smell, and hearing) and identical with the set of facts it knows at any moment.
Teadvus ei ole füüsiliselt identne närvisüsteemiga, see on “seal väljas” koos lehmaga, kogu vaatevaljas (lõhnas, kuuldekauguses) ja identne faktidega mida see hetkel teab.
