Abstract: In this paper we discuss the role of the individual in the Bohm theory, according to which a particle does appear to have an individuality, but one that is significantly different from a classical particle. In contrast however, Ladyman and Ross (2007) interpret an in-depth discussion by Brown, Elby and Weingard (1996) as implying that the properties normally associated with particles (mass, charge, etc.) are inherent only in the quantum field and not in the particles. Brown, Sjoqvist and Bacciagaluppi (1999) themselves are somewhat ambivalent suggesting that it might not be unreasonable to assume that in the Bohm theory properties such as mass and charge also reside in the particles (cf. French 2011 and French and Krause 2006). This suggests that whether or not particles are individuals in non-relativistic quantum theory is a genuinely open question in a stronger sense than Ladyman and Ross imply. After an appraisal of this discussion we go on to discuss the nature of Bohmian individuals in more detail, by considering the issue in the light of new developments in the underlying mathematical structures, due to de Gosson and Hiley.
