We see two clusters of questions arising out of the papers in this issue. The first cluster concerns the role of experience in the explanation of delusions: Do abnormal experiences play a central role in accounting for delusions, or are they at best only marginal? And if experience plays a central role in accounting for delusions, exactly what role does it play? The second cluster of questions concerns the interpretability of delusions: Are delusional utterances meaningful, or are they mere noises? And if they are meaningful, what makes it the case that they are meaningful?
