 To see that the attitude is not sufficient, imagine a situation in which physics postulates properties or objects which are like those postulated by traditional dualists; as Ney puts it imagine “it is the year 3000 AD and physicists have been forced to introduce irreducible mental entities into their theory.” (2008, p. 12). In such a situation, a person might hold the attitude Ney describes, and yet intuitively not be a physicalist.
