 Second, bare particulars individuate. Consider two objects that are exactly alike in relevant respects (they are both royal blue, weigh 1kg, and so on); what could make them two and not one? What might explain their distinctness? Since they are exactly alike in relevant respects no appeal to differences in their property-like constituents (being royal blue, weighing 1 kg, and so on) would seem to do the trick. So, the bare particularists maintain, there must be non-property-like constituents by virtue of which they are  distinct.[28]
