The Wittgenstein–Popper Poker
Ten minutes that came to symbolise the analytic-philosophy schism
Venue: Cambridge University Moral Sciences Club, King's College.
Either Wittgenstein threatened Popper with a fireplace poker, or Popper later embellished the story for effect. Witnesses disagree.
On 25 October 1946, Karl Popper gave a paper at the Cambridge Moral Sciences Club titled "Are There Philosophical Problems?" — defending the view that there are genuine philosophical problems, against (he was clear) the Wittgensteinian position that philosophy's task is to dissolve apparent problems by analysing the linguistic confusions that generate them. The meeting was chaired by Wittgenstein. Within minutes, Wittgenstein (according to Popper's 1974 autobiography) seized a fireplace poker and either gestured with it or threatened Popper, depending on the witness account; Bertrand Russell, present, may have intervened. Wittgenstein left the meeting shortly afterward. The dispute's philosophical content (philosophy as problem-solving vs philosophy as therapy) is real and consequential; the narrative of the poker has become emblematic of the analytic philosophy of the period and of the personalities involved.
Historical Context
Wittgenstein was the dominant philosophical presence at Cambridge; Popper, at the LSE since 1946, was an outsider whose *Open Society* (1945) had just made his international reputation. The meeting was Popper's introduction to Cambridge philosophy; he made no friends. The exact sequence of events is debated to this day; *Wittgenstein's Poker* (Edmonds and Eidinow, 2001) is the standard historical reconstruction.
Parties
Philosophy's task is to dissolve apparent problems by analysing the linguistic confusions that produce them; there are no genuine, substantive philosophical problems of the kind Popper presupposes.
Key arguments
- Most philosophical "problems" are misunderstandings of the logic of our language; once the misunderstanding is shown, the problem dissolves.
- Popper's assumption that philosophy advances by solving real problems imports a model from natural science that does not fit philosophy.
- The form of philosophical work is therapeutic-descriptive, not theoretical-constructive.
- Popper's paper title ("Are There Philosophical Problems?") was, on Wittgenstein's reading, framed to misrepresent the therapeutic position.
Allied schools
There are genuine philosophical problems — about induction, about scientific method, about ethics and politics — and the dismissive Wittgensteinian view that philosophy is mere linguistic therapy is itself a philosophical position vulnerable to the same kind of refutation.
Key arguments
- Real philosophical problems include the problem of induction (Hume), the problem of demarcation, and the problem of how political institutions can be reformed.
- The view that there are no philosophical problems is itself a substantive philosophical claim — and refuted by the obvious existence of problems that engaged philosophy persistently and substantively.
- Wittgensteinian therapy is, when examined, evasive: it does not engage the problems it claims to dissolve.
- Philosophy is continuous with science in being progressive, fallible, and problem-solving.

Verdict in retrospect
Wittgenstein's therapeutic conception dominated Cambridge and Oxford ordinary-language philosophy through the 1950s; Popper's critical rationalism shaped the philosophy of science and political philosophy descended from it (Lakatos, Bartley, Watkins). Neither party persuaded the other or, much, their followers; the encounter has lived on largely as a cultural-philosophical anecdote whose substantive content is sometimes overlooked.
