The Philosopher is the longest-running public philosophy journal in the UK (founded in 1923). It is the official journal of the Philosophical Society of England (PSE), a charitable organization founded ten years earlier than the journal in 1913, and still running regular groups, workshops, and conferences around the UK. As of 2019 the journal is published quarterly.

The Philosopher is built around the belief that anything can be made clear to the interested reader. Articles are considered without discrimination as to subject matter or author; the only criteria being that they must be philosophical in method and expressed in clear, understandable language.

Contributors over the years have ranged from John Dewey and G.K. Chesterton to contemporary thinkers like Mary Midgley, Timothy Williamson, Catherine Wilson, Jason Stanley, Linda Martín Alcoff, Martin Hägglund, Clare Chambers, Jemima Repo, and Adam Kotsko.
