DEFINITENESS AND PRESUPPOSITION

PRESUPPOSITION

•  Obviousfact:SpeakersconstantlymakeassumpBonsaboutwhatinformaBontheyandtheirhearersshare.

TEST FOR PRESUPPOSITION VS. TEST FOR ENTAILMENT

•  TheseteststreatpresupposiBonasasemanBcphenomenon,sincetheyarebasedontruth-condiBons.

TEST FOR PRESUPPOSITION VS. TEST FOR ENTAILMENT

•  SowhathappensifyoutrytheentailmenttestonapresupposiBon?a.TheKingofFranceisbaldpresupposesb.ThereisaKingofFrance

•  Whathappenstothetruthof(a)if(b)isfalse?•  Thisturnsouttobecontroversial.

RUSSELL’S VIEW

•  We’vealreadyseenthatforRussell,TheKingofFranceisbaldmeans,semanBcally,‘thereisoneandonlyoneKingofFranceandheisbald’: ∃x((K(x)˄∀y(K(y)→y=x))˄B(x))

•  SoforRussell:1. PresupposiBonissemanBc.2. PresupposiBonsareentailed.3. IfthepresupposiBonisfalse,theenBresentenceisfalse.

RUSSELL’S VIEW – TINY WRINKLE

•  Unfortunately,(a)and(b)bothpresuppose(c)…a.TheKingofFranceisbald. b.TheKingofFranceisnotbald. c.ThereisaKingofFrance.

•  …soforRussell,thefalsityof(c)entailsthatboth(a)and(b)arefalse…

•  …whichinturn(vianegaBon’smeaning)meansboth(d)and(e)aretrue:

d.TheKingofFranceisnotbald. e.TheKingofFranceisbald.

STRAWSON’S VIEW

•  Strawsongetsaroundtheproblembysayingthatifthere’snoKingofFrance,TheKingofFranceisbaldlacksatruth-value.

•  SoforStrawson:1. PresupposiBonissemanBc.2. IfthepresupposiBonisfalse,theenBresentenceisneithertruenorfalse.

3. “ThequesBonofwhetheritistrueorfalsesimplydoesn’tarise.”

STRAWSON’S VIEW – TINY WRINKLE

•  ThisrequiresthatweabandonabivalentsemanBcs–thatis,onethathasonlytwotruth-values(trueandfalse).

•  Instead,weneedtoallowforathirdopBonthatallowsasentencetobeneithertruenorfalse.

•  Thisgreatlycomplicatesatruth-condiBonalsemanBcs(i.e.,oneinwhichsemanBcmeaningisthatwhichaffectsthetruthofasentence).

AN ALTERNATIVE: PERHAPS PRESUPPOSITION IS PRAGMATIC

•  Inthisview,afalsepresupposiBonrendersthelargersentencecontextuallyinappropriate.

•  Advantages:1. WecankeepabivalentsemanBcs.2. WeavoidthedirectcontradicBonRussellrunsinto.3. MakesintuiBvesense:Ifthere’snoKingofFrance,whyoneartharewediscussingwhetherheisbald?

EVIDENCE FOR PRAGMATIC PRESUPPOSITION

•  VariaBoninthestrengthofpresupposiBons:TheKingofFranceisbald.[true?false?noneoftheabove?]ClarahadlunchwiththeKingofFranceyesterday.[clearlyfalse]

•  PresupposiBonsare(someBmes)defeasible/suspendable:Johnsighedbeforefinishinghissoup./Johndiedbeforefinishinghissoup.TheKingofFranceisn’tbald;thereisnoKingofFrance!TheKingofFrancelivesinParis,ifFrancehasaking.

•  They’recontext-dependent(atonepoint,Francedidhaveaking)

PRAGMATIC PRESUPPOSITION

•  Inthisview,thepresupposiBoniswhat’stakentobecommonground,non-asserted,uncontroversial,mutuallyknown,‘given’,etc.(dependingontheresearcher).
