In this chapter, I lay out the structure of the book. I begin by discussing Heidegger's theory of things, which helps lay out his phenomenology. Things are more than mere objects; they are "gatherings," the primary way we interact with the world. I then state how Heidegger lets us rethink the basis of disability studies, especially in terms of capitalism and medicine, with his two concepts of "care" and the "ontological difference." I then lay out the topics that each chapter will discuss, in specific detail.
