  3. What are word meanings? What are words? What are meanings? How are word meanings related to mental representations? How are they related to things we represent and talk about? How do word meanings combine to form phrase meanings? What are the composition operations/principles? How many “semantic types” do words and phrases exhibit? Are sentence meanings somehow special? How are meanings related to distinctively human cognition? Are linguistic expressions basically devices for communication? Are word meanings somehow “cognitively transformative”? How are linguistic meanings related to truth/denotation/satisfaction?

  4. What are word meanings? How do word meanings combine to form phrase meanings? How are meanings related to distinctively human cognition? We have to start somewhere...preferably, not on a dead end street.

  5. What are word meanings? How do word meanings combine to form phrase meanings? How are meanings related to distinctively human cognition? Focus on the languages that human children can naturally acquire. Substantive Choice: we could start in a very different way... --ask what languages/expressions/meanings might be, --abstract away from current theories of human languages, --adopt some a priori constraints on the Very Idea of a Language, --and view human languages/expressions/meanings as special cases

  6. What are word meanings? How do word meanings combine to form phrase meanings? How are meanings related to distinctively human cognition? Focus on the languages that human children can naturally acquire. spoken or signed languages...spontaneous human articulations young children...infants/toddlers, as if undergoing metamorphosis  naturally acquire without training...often impervious to correction constrained homophony..."Poverty of the Stimulus Revisited" The duck is ready to eat. (duck as eater, duck as eaten) The duck is eager to eat. (duck as eater, #duck as eaten) The duck is easy to eat. (#duck as eater, duck as eaten)

  7. What are word meanings? How do word meanings combine to form phrase meanings? How are meanings related to distinctively human cognition? Focus on the languages that human children can naturally acquire. Two Hypotheses: (D) for each human language, there is a theory of truth that is also the core of an adequate theory of meaning for that language (C) each human language is a biologically implementable procedure that generates expressions, which exhibit constrained homophony

  8. Human Language: a language that human children can naturally acquire (D) for each human language, there is a theory of truth that is also the core of an adequate theory of meaning for that language (C) each human language is ani-language: a biologically implementable (and hence constrained) procedure that generates expressions, which connect meanings of some kind with articulations of some kind (B) each human language is an i-language for which there is a theory of truth that is also the core of an adequate theory of meaning for that i-language

  9. Human Language: a language that human children can naturally acquire (D) each human language is Davidsonian (C) each human language is an i-language: a biologically implementable (and hence constrained) procedure that generates expressions, which connect meanings of some kind with articulations of some kind (B) each human language is an i-language for which there is a theory of truth that is also the core of an adequate theory of meaning for that i-language

  10. Human Language: a language that human children can naturally acquire (D) each human language is Davidsonian (C) each human language is Chomskian (B) each human language is an i-language for which there is a theory of truth that is also the core of an adequate theory of meaning for that i-language

  11. Human Language: a language that human children can naturally acquire (D) each human language is Davidsonian (C) each human language is Chomskian (B) each human language is both Davidsonian and Chomskian

  12. Human Language: a language that human children can naturally acquire (D) each human language is Davidsonian (C) each human language is Chomskian (B) each human language is both Davidsonian and Chomskian (D) & (C)(B) not-(B) & (C)not-(D) not-(B) & (D) not-(C) (B) is very implausible (C) is more plausible than (D)

  14. Human Language: a language that human children can naturally acquire (D) for each human language, there is a theory of truth that is also the core of an adequate theory of meaning for that language (C) each human language is an I-language: a biologically implementable (and hence constrained) procedure that generates expressions, which connect meanings of some kind with articulations of some kind (M) these human i-language meanings are instructions for how to build concepts that are that are massively monadic and conjunctive June 13 June 20, 27

  15. Human Language: a language that human children can naturally acquire (D) for each human language, there is a theory of truth that is also the core of an adequate theory of meaning for that language today, focus on some expressions that were supposed to make (D) look good: predicates that are allegedly true of “events” next week, i-languages, Liar Sentences, and a worry about how to squeeze a meaning theory (for a human i-language) out of a truth theory along the way, worries about expressions (e.g., ‘London’) that allegedly denote entities Many other reasons for doubting (D)

  16. They thought that Hesperus is a star, and that The Moon is a planet. They thought that Neptune and Vulcan are planets. (Here is your coffee.) There is some milk in the refrigerator. (You’re not done cleaning up.) There is some milk in the refrigerator. (Austin-Travis) The refrigerator is ready. I prefer the rabbit. (Bach-Recanati-Nunberg)

  18. Event Variables and Framing Effects

  19. Outline • Framing effects (e.g., Kahnemanand Tversky) • Some puzzles concerning natural language “event variables” Two chipmunks chased each other. Alvin joyfully chased Theodore, who joylessly chased Alvin. There was an event, e1, of Alvin chasing Theodore joyfully. There was an event, e2, of Theodore chasing Alvin joylessly. Was e1 (identical to) e2?

  20. Outline • Framing effects (e.g., Kahnemanand Tversky) • Some puzzles concerning natural language “event variables” Two chipmunks chased each other. Alvin joyfully chased Theodore, who joylessly chased Alvin. Simon played a song dramatically on his tuba in two minutes. Simon played his tuba for two minutes. There was an event, e1, of Simon playing a song... There was an event, e2, of Simon playing his tuba... Was e1 (identical to) e2? *Simon played his tuba dramatically on his tuba in two minutes.

  21. Outline • Framing effects (e.g., Kahnemanand Tversky) • Some puzzles concerning natural language “event variables” Two chipmunks chased each other. Alvin joyfully chased Theodore, who joylessly chased Alvin. Simon played a song dramatically on his tuba in two minutes. Simon played his tuba for two minutes. • With regard to alleged “values of” these event variables... • Argue against identity responses to the puzzles • Argue against non-identity responses to the puzzles • Given a truth-theoretic conception of linguistic meaning, certain “event framing effects” yield paradoxes

  22. I Cognize, ergoI am prone to Framing Effects Examples via Kahneman’s recent book, Thinking Fast and Slow A bat and a ball cost $1.10 The bat costs a dollar more than the ball How much does the ball cost? Hint: NOT ten cents…a dollar is not a dollar more than ten cents Adam and Beth drive equal distances in a year. Adam switches from a 12-mpg to 14-mpg car. Beth switches from a 30-mpg to 40-mpg car. Who will save more gas? Adam: 10,000/12 = 833 10,000/14 = 714 saving of 119 gallons Beth: 10,000/30 = 333 10,000/40 = 250 saving of 83 gallons

  23. I Cognize, ergoI am prone to Framing Effects Examples via Kahneman’s recent book, Thinking Fast and Slow Adam and Beth drive equal distances in a year. Adam switches from a 1/12-gpm to 1/14-gpm car. Beth switches from a 1/30-gpm to 1/40-gpm car. Who will save more gas? Adam: 1/12 = .083 1/14 = .071 difference = .012 Beth: 1/30 = .033 1/40 = .025 difference = .008

  24. Schelling Effect Suppose your tax depends on your income and how many kids you have. • The “child deduction” might be flat, say 1000 per child Tax(i,k) = Base(i) – [k• 1000] • Or it might depend on the taxpayer’s income Tax(i,k) = Base(i) – [k• Deduction(i)] Q1: Should the child deduction be larger for the rich than for the poor? Instead of taking the “standard” household to be childless, we could lower the base tax for everyone (e.g., by 3000), and add a surcharge for households with less than 3 kids (e.g., 1000/2000/3000). We could also let the surcharge depend on income. Tax(i,k) =LowerBase(i) + [(3 –k) • Surcharge(i)] Q2: Should the childless poor pay as large a surcharge as the childless rich?

  25. Schelling Effect Q1: Should the child exemption be larger for the rich than for the poor? Q2: Should the childless poor pay as large a surcharge as the childless rich? if you answered ‘No’ to both, then you are not endorsing a coherent policy as Kahneman puts the point… the difference between the tax owed by a childless family and by a family with two children can be described as a reduction or as an increase if you want the poor to receive at least the same benefit as the rich for having children, then you must want the poor to pay at least the same penalty as the rich for being childless.

  26. 1. ~[Deduction(r) > Deduction(p)] Desire 2. Surcharge(p) < Surcharge(r) Desire 3. for any income i, Surcharge(i) = Deduction(i) obvious, but also provable 4. Surcharge(r) = Deduction(r) [3] 5. Surcharge(p) < Deduction(r)seems OK [2, 4] 6. Surcharge(p) = Deduction(p) [3] 7. Deduction(p) < Deduction(r)seems bad [5, 6] 8. Deduction(r) > Deduction(p) [7] 9.  [1, 8]

  27. Kahneman’s Conclusion “The message about the nature of framing is stark: framing should not be viewed as an intervention that masks or distorts an underlying preference. At least in this instance...there is no underlying preference that is masked or distorted by the frame. Our preferences are about framed problems, and our moral intuitions are about descriptions, not substance.” Maybe it’s not this bad with regard to the moral/political. (As the village semanticist, I take no stand.) But there is no guarantee that our “intuitions” have stable propositional contents.

  35. One Event, Described Many Ways Alvin chased Theodore. e[Chased(e, Alvin, Theodore)] Alvin chased Theodore joyfully. e[Chased(e, Alvin, Theodore) & Joyful(e)] Alvin chased Theodore around a tree. e[Chased(e, Alvin, Theodore) & x{Around(e, x) & Tree(x)}] Alvin chased Theodore joyfully around a tree. e[Chased(e, Alvin, Theodore) & Joyful(e) & x{Around(e, x) & Tree(x)}]

  36. One Event Described Many Ways? Alvin chased Theodore. e[Chased(e, Alvin, Theodore)] Theodore fled from Alvin. e[Fled(e, Theodore) & From(e, Alvin)] e[Fled(e, Theodore, Alvin)] DISTINGUISH: the chasing by Alvin of Theodore is distinct from the fleeing by Theodore from Alvin different subjects, different “objects” IDENTIFY: the (event of) fleeing is the (event of) chasing same spatiotemporal region, same participants

  37. One Event Described Many Ways? Alvin chased Theodore. e[Agent(e, Alvin) & PastChaseOf(e, Theodore)] Theodore fled from Alvin. e[Agent(e, Theodore) & PastFleeFrom(e, Alvin)] DISTINGUISH: the chasing by Alvinof Theodore is distinct from the fleeing by Theodore from Alvin different Agents, different “second” participants

  38. One Event Described in Many Ways? Alvin chased Theodore joyfully. e[Agent(e, Alvin) & PastChaseOf(e, Theodore) & Joyful(e)] Theodore fled from Alvin joylessly. e[Agent(e, Theodore) & PastFleeFrom(e, Alvin) & Joyless(e)] DISTINGUISH: the chasing by Alvinof Theodore is distinct from the fleeing by Theodore from Alvin different Agents, different “second” participants the chasing was (done by Alvin and) joyful the fleeing was (done by Theodore and) joyless

  39. One Event Described Many Ways? Alvin chased Theodore joyfully and athletically, but not skillfully. e[Chased(e, Alvin, Theodore) & J(e) & A(e) & ~S(e)] Theodore chased Alvin joylessly and unathletically, but skillfully. e[Chased(e, Theodore, Alvin) & ~J(e) & ~A(e) & S(e)] DISTINGUISH: the chases exhibit different properties that can be specified adverbially or thematically IDENTIFY: same sortal (‘chase’), same participants, same spatiotemporal region no two ships/statues/people/chipmunks/chases in the same place at the same time

  40. One Event Described Many Ways? Alvin chased Theodore joyfully and athletically, but not skillfully. e[Chased(e, Alvin, Theodore) & J(e) & A(e) & ~S(e)] Theodore chased Alvin joylessly and unathletically, but skillfully. e[Chased(e, Theodore, Alvin) & ~J(e) & ~A(e) & S(e)] DISTINGUISH, but RELATE: e1 ≠ e2, but e1 ≈ e2 IDENTIFY, but RELATIVIZE: a big ant can be a small animal; a creature that is big for an ant can be a small for an animal

  41. One Event Described Many Ways? Alvin chased Theodore joyfully and athletically, but not skillfully. e[Chased(e, Alvin, Theodore) & J(e) & A(e) & ~S(e)] Theodore chased Alvin joylessly and unathletically, but skillfully. e[Chased(e, Theodore, Alvin) & ~J(e) & ~A(e) & S(e)] DISTINGUISH, but RELATE: e1 ≠ e2, but e1 ≈ e2 IDENTIFY, but RELATIVIZE: a quick swimming of the Channel can be (an event that is also) a slow crossing of the Channel; an event can be joyful qua chase-by-Alvin yet joyless qua chase-by-Theodore

  42. On the one hand... Hilary and Ainsley kissed. Each kissed the other, quite happily. The activity was fully cooperative. Nonetheless... Hilary kissed Ainsley a little more energetically than Ainsley kissed Hilary. Ainsley kissed Hilary a little more softly than Hilary kissed Ainsely. Perhaps we can and should posit two kissings. So perhaps it’s OK to posit two chasings.

  43. On another hand... Positing two facings/playings seems less plausible. So do we really have good reasons for proliferating chasings (or even kissings)? Carnegie Deli faces Carnegie Hall. Carnegie Hall faces Carnegie Deli. Simon played a song on his tuba. Simon played his tuba. *The Kisses

  44. On a third hand... Simon played the song dramatically on his tuba in two minutes. Simon played his tuba for two minutes. ?? Simon played his tuba dramatically on his tuba in two minutes. Do we have to proliferate playings after all?

  45. Outline ✓ Framing effects (e.g., Kahnemanand Tversky) ✓ Some puzzles concerning natural language “event variables” The chipmunks chased each other. Alvin joyfully chased Theodore, who joylessly chased Alvin. Simon played a song dramatically on his tuba in two minutes. Simon played his tuba for two minutes. • With regard to alleged “values of” these event variables... • Argue against identity responses to the puzzles • Argue against non-identity responses to the puzzles • Given a truth-theoretic conception of linguistic meaning, certain framing effects are paradoxical

  46. Against Simple Identity: NonEntailments Simon played the song dramatically/on his tuba/in two minutes. e[Played(e, Simon, the song) & Φ(e)] Simon played his tuba skillfully/melodiously/for two minutes. e[Played(e, Simon, his tuba) & Ψ(e)] ? Simon played the song skillfully/melodiously/for two minutes. ? e[Played(e, Simon, the song) &Ψ(e)] It seems to depend on the details and operative standards.

  47. Against Simple Identity: NonEntailments Simon played the song dramatically/on his tuba/in two minutes. e[Played(e, Simon, the song) & Φ(e)] Simon played his tuba skillfully/melodiously/for two minutes. e[Played(e, Simon, his tuba) & Ψ(e)] ?? Simon played his tuba dramatically/on his tuba/in two minutes. ?? e[Played(e, Simon, his tuba) & Φ(e)] Here, identification just seems wrong.

  48. So maybe we should Distinguish after all... Simon played the song. e[Played(e, Simon, the song)] Played(e1, Simon, the song) Simon played his tuba. e[Played(e, Simon, his tuba)] Played(e2, Simon, his tuba) DISTINGUISH, but RELATE: e1 ≠e2, but e1 ≈e2 My Claim: while this strategy is plausible for some cases, it is not plausible for these cases

  49. Plausible Cases of “Distinct but Related” • Booth shot Lincoln with a pistol • Booth pulled the trigger with his finger It seems that (modulo some niceties) the pulling was a part of the shooting... the pulling ended before the shooting did • Booth didn’t shoot Lincoln with his finger • Booth didn’t pull the trigger with a pistol • Booth pulled the trigger long before Lincoln died ? Booth killed Lincoln long before Lincoln died It seems that (modulo some niceties) the trigger-pulling was a nonfinal part of the killing |---------|-----------|----------| finger trigger pistol squeezed pulled shot
