Identical Particles in Quantum Mechanics: Against the Received View

Abstract

According to the Received View identical quantum particles are a previously unknown kind of objects that do not possess individuality. In this Chapter we discuss this view, criticize it, and propose an alternative. According to this alternative view so-called identical quantum particles should in many cases not be seen as objects (particles) at all. However, there are situations in which a particle picture does become applicable. But the particles that emerge in these cases are distinguishable individuals, unlike the particles of the Received View.
