 Is Geach’s argument at least an argument that identity is relative? Does language relativity support the conclusion that RI is true even of identity as formalized in FOL\(^=\)? The general idea appears to be that language relativity suggests that we take identity to be indiscernibility, and conclude that objects identical relative to one ideology \(F\) may be different relative to another ideology \(G\), and that this confirms RI. Notice first of all that this argument relies on the identity of indiscernibles: that indiscernibility implies identity. This principle is not valid in FOL\(^=\) even when the latter is treated as a proper theory. Language relativity does not imply that the distinctness of distinct objects cannot go unnoticed.
