 The account given in these five points has the advantage that it is compatible with the fact that most identities involving reidentification are categorisable under sortals, but that there are other cases—such as ‘piece of…’, ‘hunk of…’—where this is not so. It also avoids the need to employ the ‘“is” of constitution’ to link sortals and particulars, like lumps and hunks, rather than just mass terms, such as ‘clay’ or ‘gold’. The case where the lump and the sortally individuated object do not coincide, applies only to some problematic artefactual cases, and in those cases the sortal name of the artefact will not be suitable substitute for F, but the ‘lump’ expression will be. In that way, it will be possible to avoid the need to have two material objects in the same place.
