E. H. Carr's injunction that “when we take up a work of history, our first concern should be not with the facts which it contains but with the historian who wrote it” is well justified by the current state of research in the field of Iberian cryptojudaism and its subsequent development outside the peninsula. As in the study of Iberian history itself, vested interests, strong personal biases, and allegiances to national or partisan schools of historiography have frequently stood in the way of dispassionate inquiry into the subject and led to polarizaton and obfuscation. Over and above this, fruitful study has been impeded by the “blind-men-and-the-elephant” fallacy.
