Immunity to Error and Subjectivity

Since Sydney Shoemaker published his seminal article ‘Self-Reference and Self-Awareness’ in 1968, the notion of ‘Immunity to Error through Misidentification’ (IEM) has received much attention. It crops up in discussions of personal identity, indexical thought and introspection, and has been used to interpret remarks made by philosophers from Wittgenstein to William James. The precise significance of IEM is often unspecified in these discussions, however. It is unclear, for example, whether it constitutes an important status of judgments, whether it explains an important characteristic of judgments, or whether it merely marks an important characteristic of judgments. Nevertheless, reference to IEM abounds, making this obscure notion seem all the more significant.
