Abstract
This article investigates how lack of a phenomenology of technology has hurt understanding of the lifeworld. One way, as Ihde has shown, involves a failure to appreciate the instrumental mediation of experience and the extension of perception. But Ihde also fails to notice the background in which these mediations are taking place and which shapes the mediations themselves and our interpretation of them; not even the research of technoscientists takes place in a neutral atmosphere that does not affect how we work. This article also discusses hermeneutic distortion, or the gap in collective interpretive resources that occurs when the technoscientific infrastructure withdraws and becomes all but invisible, encouraging the tendency to treat scientific conclusions as mere opinions, and technoscientific devices as accessory rather than integral to the modern world.
