What is the value of public philosophy? “Philosopher-first” accounts suggest that the ideas that academic philosophers produce can, when disseminated, be useful to the wider public. However, such accounts assume that there is a gap between the interests and activities of professional philosophers and those of the wider public, which must be overcome by translating philosophy into more accessible terms. This article offers an alternative account—the “public-first” account. On this account, philosophy is a necessary part of everyday life. Each of us relies upon a background of conceptual resources that shape our interpretations, expectations, and behaviours in the world. Professional philosophers might be useful in analysing, maintaining, and fixing our conceptual infrastructure. However, there is no gap between philosophy and everyday life, which must be overcome. Whilst most defences of public philosophy argue that it is beneficial to the public, on the “public-first” account, public philosophy is also vital for the discipline of philosophy itself. If philosophers want to adequately evaluate their philosophical theories, they must appeal to a much wider and more diverse range of human experience than that of professional philosophers themselves. As such, public philosophy is necessary for properly conducted philosophical inquiry.
