Abstract
Chapter 3 reconsiders disability studies' founding concern with medicine through Heidegger's phenomenology. I suggest Heidegger's reframing of truth as disclosedness, or the Greek Aletheia, lets us reframe these concerns along his fundamental ontology. After outlining Heidegger's understanding of truth, I review the relevant literature, looking to the social model of disability, other phenomenological approaches, and similar, but more recent, interpretive perspectives. I suggest that medicalization not only refers to medical practices, but models that see disability only in terms of restricted function. I make sense of this using the case of rehabilitation science, and three measures employed therein. Two are numerical measures; the interview is the third. I end by discussing future work in rehabilitation.
