By topic/modality

Classification by topic/modality.

Topics:

  • (MD) Doxastic (belief). (Lottery, Moore, Dutch book–style arguments.)

  • (ME) Epistemic (knowledge, evidence). (Knower, Fitch)

  • (MS) Truth-theoretic / meaning-theoretic (Liar, Yablo, Grelling).

  • (MP) Pragmatic (speech-act coherence). (Moore’s paradox in its assertion reading, Performative Contradictions, Kapitan’s paradoxes, etc.)

  • (MP’) Performative is a subtype of Pragmatic (Austin/Searle-inspired sub-class devoted to acts that fail by being performed, e.g., “I hereby forbid all forbiddings”.

    Pragmatic paradoxes: the clash is with norms of assertion / conversation / belief avowal (e.g., Moore’s paradox: “p, but I don’t believe p”). The paradox arises from what you assert relative to your mental state or the conversational score.

    Performative paradoxes: the clash is with the felicity conditions of the very speech act you are performing (Austin/Searle style). The utterance as an act defeats its own success conditions.

  • (MN) Normative / Deontic. Good (Ross’s paradox, Good Samaritan, Chisholm).

  • (MR) Referential / Intentional Objects (Useful for Meinongian-style puzzles, nonexistents, impossible objects, and some definite-description paradoxes)

  • (MV) Vagueness / Soritical (sorites, higher-order vagueness, heap puzzles).

  • (MG) Decision-/Game-theoretic & Rationality (Newcomb, Prisoner’s Dilemma pathologies, Ellsberg, St. Petersburg, Pasadena, Sleeping Beauty, Pascal’s Wager - which can be considered as doxastic, but it squarely lives in decision theory too. These mix normative, epistemic, and utility-theoretic ingredients—worth its own tag.)

  • (MT) Time-travel (grandfather, bootstrap), knowledge over time (McGee-style dynamic paradoxes), causal loops. These clash with modal-temporal structure more than with truth or belief per se.

  • (MC) Computational / Recursion-theoretic (Halting problem, Rice, Kleene–Rosser, diagonalization in computation, Busy Beaver “paradoxes”.)

  • (MI) Set-theoretic / Infinite / Size. (Russell, Burali-Forti, Cantor’s paradox, Skolem’s paradox, Banach–Tarski.)

  • (MA) Aggregation / Social-choice / Judgment (Condorcet cycles, discursive dilemma, Arrow, Sen. They are normative+epistemic+structural, but again: distinctive enough to tag.)

  • (MW) Free Will.
