The book illustrates why disability must be assessed within a particular society's social, political, and medical context, and also the importance of bringing medical history into conversation with cultural history. A Euro-American-centric disability studies perspective that focuses on disability and oppression, the author contends, risks overlooking the unique situation in a non-Western society like Japan in which disability was constructed to enhance blind people's power. He explores what it meant to be blind in Japan at that time, and what it says about current frameworks for understanding disability.
