While a number of important individual works were published in the second half of the twentieth century, Paul Durbin has identified two books published at the turn of the century as marking the development of the philosophy of technology as an academic subdiscipline with canonical texts.[8] Those were Technology and the Good Life (2000), edited by Eric Higgs, Andrew Light, and David Strong and American Philosophy of Technology (2001) by Hans Achterhuis. Several collected volumes with topics in philosophy of technology have come out over the past decade and the journals Techne: Research in Philosophy and Technology (the journal of the Society for Philosophy and Technology, published by the Philosophy Documentation Center) and Philosophy & Technology (Springer) publish exclusively works in philosophy of technology. Philosophers of technology reflect broadly and work in the area and include interest on diverse topics of geoengineering, internet data and privacy, our understandings of internet cats, technological function and epistemology of technology, computer ethics, biotechnology and its implications, transcendence in space, and technological ethics more broadly.
