What Things Do is an important contribution to philosophy of technology. Peter-Paul Verbeek has undertaken the challenge of linking this field to current technology studies, with promising results. The main figures on whom he focuses are Martin Heidegger, Don Ihde, and Bruno Latour. His account of their thought is lucid and convincing. The synthesis at which he aims offers a starting point rather than a destination, but it is a useful starting point from which to develop and deepen work in philosophy of technology.
