Intellectual Disability: Ethics, Dehumanization, and a New Moral Community presents an interdisciplinary exploration of the roots and evolution of the dehumanization of people with intellectual disabilities. Chapters examine how an intellectual and cultural foundation was established for the claim that morality requires a narrowly defined form of rationality--a belief the authors contend has contributed to widespread discrimination against, and marginalization of, those with limited cognitive skills. Offering valuable insights for moral philosophers, psychologists, and educators, the book reinforces the importance of an interdisciplinary understanding of the social construction of intellectual disability and offers a more expansive view of moral engagement.
