Should philosophy help address the problems of non-philosophers or should it be something isolated both from other disciplines and from the lay public? This question became more than academic for philosophers working in UK universities with the introduction of societal impact assessment in the national research evaluation exercise, the REF. Every university department put together a submission describing its broader impact in case narratives, and these were graded. Philosophers were required to participate.The resulting narratives are publicly available and provide a unique resource permitting a more comprehensive, empirically based consideration of philosophy's influence outside the academy than has hitherto been possible. This paper takes advantage of this to develop a taxonomy of the ways in which philosophers engage society in their work. We identify five approaches: dissemination, engagement, provocations, living philosophy, and philosophy of X. We compare these along the six dimensions proposed by Frodeman and Briggle to characterize the ideal field philosopher. We conclude that there are multiple ways of being a field philosopher, which vary in their emphasis. This pluralism bodes well for the expansion of philosophy's societal influence, since there are routes available to suit different preferences.The STEM disciplines (science, technology, engineering, and math) can make arguments concerning their contributions to health care, technological advance, economic growth and the like. But this isn't the case with philosophy and the humanities. (22) Soon enough, they warn, society will come to the philosophers and ask us to account for our activities. What, pray tell, is the value of philosophy? This question has long been an uncomfortable one. A 1986 satirical British novel about the commercialization of universities focuses on the philosophy department, presumably because philosophy is the field of which it is most difficult to envisage commercialization. The fictional Vice Chancellor took the position that:Philosophy has got to earn its keep, just like any other subject. The days of the ivory tower were over long ago. It's not all that difficult to adjust to the real world. Your colleagues in other departments have shown what can be done with a bit of ingenuity. (Parkin 1986, p. 17) In response, the philosophy dean opened the "Mind and Body Shop" in the red light district.This debate, such as it is, has become more than academic for philosophers working in UK universities. UK universities are subject to periodic national evaluations of research quality, which for the first time in 2014 incorporated assessment of the broader societal impact of research. This exercise, the Research Excellence Framework (REF), helps allocate core university funding. Every university department puts together a submission describing its efforts, and these are reviewed by disciplinary panels that award a grade. Case study narratives were developed to support assessment of broader societal impacts.
