castle studies

All kinds of historians commit fallacies, but I often read work in the field of castle studies which commits a specific one. It goes like this: “if a site’s defenses (as visible in the archaeological record) were imperfect, the defenses (which actually existed) were useless and merely for show.” This is related to false dilemmas, the Nirvana Fallacy, and “the perfect is the enemy of the good.” It is linked to the fashion among some Anglo intellectuals for declaring that human life is really governed by arbitrary social conventions and nothing so coarse as contact with the external physical world.
