What matters is what happen in the outside. We don't know what happen in our inside (or the inside of others, at least), we know the language and how it is used, event the meanings don't have to be the same as long as it is consistent. And you get that by construction. Does that mean intelligence, self consciousness, soul or whatever? We only know that it walk like a duck and quacks like a duck.
