The theory of rationality has traditionally been concerned with the investigation of the norms of rational thought and behaviour, and with the reasoning procedures that satisfy them. As a consequence, the investigation of irrationality has largely been restricted to the behaviour or thought that violates these norms. There are, however, other forms of irrationality. Here we propose that the delusions that occur in schizophrenia constitute a paradigm of irrationality. We examine a leading theory of schizophrenic delusion and propose that some delusions can be traced to a violation of a condition on thought we call egocentricity. We argue that the violation of egocentricity leads to irrational states that cannot be explained by the traditional categories of irrationality and conclude, therefore, that these states belong in a new branch of the theory of irrationality, that of experiential irrationality.
