Don Ihde is one of the world's foremost thinkers on the place of technologies in our lives. Over the course of a long career, he has built a unique and useful perspective by expanding on phenomenological and American pragmatist philosophy and has developed wide-ranging insights and conceptual tools for describing the details of our experience across the various areas of human activity, including scientific practice, anthropological history, computer interface, design, art history, and the technologies of everyday life. The Critical Ihde brings together many of Ihde's most influential writings, as well as a number of under-recognized gems. Across these works are examples of his influential contributions to the phenomenology of human auditory and visual experience, his foundational work on the phenomenology of technology, and his thoughts on the technologies of scientific practice, including laboratory and medical imaging. Further, these chapters reveal the development of "postphenomenology, " Ihde's original philosophical perspective, one that continues to flourish today across the work of a growing interdisciplinary and international collective of scholars.
