Intuition Pumps and Other Tools for Thinking

Dennett's collection of seventy-seven thinking tools — thought experiments, heuristics, and argumentative moves that he has developed over a lifetime as a philosopher of mind.
The tools range from Occam's Razor and reductio ad absurdum to Dennett's own inventions ("surely" as a warning sign, the "Deepity", staging your intuition before trusting it).
For product direction the book is not directly applicable and that is the point — it trains the kind of disciplined reasoning that makes every other application sharper.
Dennett writes with unusual clarity for a philosopher, and the book is designed to be dipped into rather than read cover-to-cover.
Read alongside his Kinds of Minds for the more focused treatment of consciousness.
Central argument
Dennett argues that good thinking is a craft that can be taught through concrete, reusable tools — 'intuition pumps' — rather than through abstract logical training alone. The book's central claim is that most philosophical and intellectual errors stem not from stupidity but from poorly staged intuitions: we trust gut reactions before subjecting them to disciplined examination. By cataloguing seventy-seven such tools, from classical moves like reductio ad absurdum to Dennett's own inventions like spotting 'surely' as a rhetorical alarm bell or diagnosing a 'Deepity' (a statement that sounds profound but collapses under scrutiny), he proposes that metacognitive habits are the actual substrate of rigorous reasoning.
Critique
The book's structure as a browsable compendium of tools is also its main liability: without a unifying framework for when to reach for which tool, the collection risks becoming a sophisticated form of intellectual eclecticism — one can cherry-pick whichever heuristic supports a conclusion already reached. A thoughtful reader might also note that many of the tools were forged in philosophical debates about consciousness and free will, domains where clarity of argument is the primary currency; product and organizational contexts add social, political, and temporal constraints that Dennett's toolkit largely brackets. The implicit assumption that clearer thinking is the binding constraint on good decisions flatters the audience but may underestimate how often the problem is incentive misalignment, not reasoning quality.
Why it matters for product
For a product leader, the most transferable tool is Dennett's warning about 'surely' — any time a product brief, strategy document, or roadmap rationale leans on an unexamined assumption presented as obvious ('users surely won't tolerate friction here', 'the market surely wants simplicity'), it is a signal to stop and stage the intuition before committing resources. More broadly, the discipline of identifying 'Deepities' maps directly onto product strategy work, where vision statements and OKRs frequently achieve the appearance of depth by being interpretable in both a trivial and a sweeping sense — a habit that survives precisely because it allows alignment theatre without actual alignment.
