This book explores the 'material-discursive entanglement' of how we both make the world with our words and how the materiality of the world forces us to put words on it. Beginning with the conundrum of how the things that make up our world are both shaped by and shape the ways in which we talk about, engage with and think about them, the author accepts the entanglement and then works backwards, using the metaphor of refraction to help articulate the structures, values and norms that discursively shape our world and our selves in it. Through a series of empirical examples taken from work on medical technologies and the body, Refracting through Technologies shows how researchers and designers can use material things - technologies - to refract discourses and articulate the concerns and voices producing them. Refraction as a metaphor is thus revealed to be an important concept, enabling scholars to apply analytical work to political concerns about the technological world. As such, it will appeal to scholars of sociology, science and technology studies, philosophy and design with interests in technoscience, feminist thought and social theory.
