 This analysis shows that one can consider at all levels (the micro and the macroscopic ones) the field \(m(\mathbf{x},t)\) as accounting for ‘what is out there’, as originally suggested by Schrödinger with his realistic interpretation of the square of the wave function of a particle as representing the ‘fuzzy’ character of the mass (or charge) of the particle. Obviously, within standard quantum mechanics such a position cannot be maintained because
