Wybo Houkes and Pieter Vermaas have developed ICE theory in close contact with the engineering literature on designing and the literature on functions in the philosophy of biology and philosophy of mind. As such the book is a telling example of the successful new school of philosophy of technology that is aimed at understanding engineering and technology on their own merits.

The book presents the reader with a broad and detailed understanding of technical artefacts and their functions, which is sensitive to the dynamic and socially structured practices of using and designing. This understanding shows how our technology-saturated everyday life can be subjected to rigorous philosophical analysis, and how artefacts and technical functions provide an area of inquiry that is equally fascinating as, but genuinely different from, biological items and their functions.
