 Advocates of relative identity deny that there is a single identity relation (see Geach 1967, Griffin 1977). On their view it is improper to ask whether, say, the statue is the same thing as the later lump of clay. Instead we should ask whether it is the same statue, or the same lump of clay. For an advocate of relative identity denying that the earlier statue is the same statue as the later lump of clay is consistent with allowing that the earlier statue is the same lump of clay as the later lump of clay. It is natural for the relative identity theorist to insist on relativising the transitivity of identity to the same sortal concept in the following way. What the relativised transitivity principle says is that: a is the same F as b, and b is the same F as c implies only that a is the same F as c (see Griffin 1977).
