“Each wall serves the same function: it redirects attention from the actual causes of disease toward explanations that generate dependence on the medical system. Many readers have already seen through one or more of the earlier walls. The genetics wall captures even those who have seen through the rest, because the genetics wall is the wall that wears your face. To question a genetic diagnosis can feel like questioning your own existence. That is what makes it so effective, and it is what makes this book necessary.”
