Book excerpt: "Ihde is perhaps uniquely situated to provide authoritative accounts of such diverse philosophical traditions as those involved in current explorations of the technology of scientific instruments.... Ihde's book breaks new ground and... makes an important debate accessible." --Robert Ackermann Instrumental Realism has three principal aims: to advocate a "praxis-perception" approach to the philosophy of science; to explore ways in which such an approach offers a mutually illuminating overlap with a philosophy of technology; and to examine comparatively and critically the work of some who advocate an "instrumental realist" approach to the philosophy of science.
