TruthasImmanent

Recallwhereweare:I’vesaidthatpluralistsshouldbe—indeed,havetobe—functionalists.Thepropertiesinvirtueofwhichpropositionsaretruearethosethatplaythetruth‐role.Whatconstitutesapropertyplayingthatroleisit’shavingthetruishfeatures.Butoursecondquestionisstilloutstanding:whatdothesepropertieshavetodowithtruth?

Inordertoanswerthisquestion,thepluralistcumfunctionalistneedstwothings.Sheneedsanaccountofwhatfunctionalistssometimescall“realization”andsheneedsanaccountofthepropertytruthitself.

Ithinkwecanmeetbothdemandsatonce.Startwiththethoughtthatpropertiescanhavetheirfeaturesessentiallyoraccidentally.Afunctionalpropertyisdefinedbyitsfunctionalrole,which,I’vesuggested,isbestseenasthesumofthoserelationalfeaturesimplicitinthenominalessenceoftheproperty.Thosefeaturescanthereforebethoughttobeessentialtoit.Thus,forthefunctionalist,thenaturalsuggestionistoequatethepropertyoftruthwiththepropertythathasthetruishfeaturesessentiallyorwhichplaysthetruth‐roleassuch.Itisthepropertythatis,necessarily,hadbybelievedcontentsjustwhenthingsareastheyarebelievedtobe;hadbypropositionsbelievedattheendofinquiryandwhichmakespropositionscorrecttobelieve.

ofFisanessentialfeatureofFthat(a)ispartofthenominalessenceofF;(b)holdsasamatterofconceptualnecessity;andso,(c)helpstodistinguishFfromotherproperties.Sinceeveryproperty’sconceptuallyessentialfeaturesareasubsetofitsownfeatures,everypropertymanifestsitself.Soimmanence,likeidentity,isreflexive.Butunlikeidentity,itisnon‐symmetric.WhereMandFaredistinct—individuatedbynon‐identicalsetsofconceptuallyessentialfeaturesandrelations—andFisimmanentinM,Misnotimmanentintruth.Intuitivelyput,whereFisimmanentinM,itwillbethecasethatpartofbeingMisbeingF.

Appliedtotruth,theinitialthoughtisthis:forsomepropositions,truthismanifestedby,orimmanentintheircorrespondencetovariousbitsofreality.Partofwhatisforthosepropositionstocorrespondisforthemtobetrue.Justasthepsychologicalfunctionalistwillclaimthatwhichphysicalpropertyrealizespaininagivenorganismisdeterminedbyfactsabouttheorganism,thealethicfunctionalistwillclaimthatwhichpropertymanifeststruthforaparticularpropositionwilldependonfactsaboutthatproposition.Twokindsoffactareclearlyrelevant.Thefirstiswhatthepropositionisabout.Thesecondistheproposition’slogicalstructure.

Thissecondpointisnotsurprising.Thataproposition’slogicalstructureshouldhelptodeterminehowitistrueisfamiliarfromtraditionalcorrespondenceviews,accordingtowhichtheonlysortofpropositionsthatcorrespondtofactsareatomic.Similarly,whichpropertymanifeststruthforapropositiondependsonwhetheritisatomicornot.Howweunderstandthis,however,dependsonhowweunderstandthefirstsortoffact.

InTOM,IsuggestedthatpluralistsholdthattruthforatomicsisalwaysmanifestedrelativetowhatIcalledadomainofinquiry.AsIdefinedit,apropositionaldomainisasubject‐matter:mathematicsandethicsaretwoexamples.Howdoweknowwhetherapropositionisaboutonesubjectratherthananother?Howelse?Bylookingattheobjectsandpropertiestheconceptswhichcomposethatpropositionareabout.

Istilltakethistobefairlystraightforward.Almostanyphilosopherwillthinkthattherearedifferentkindsofcontent,andwilltakeitforgrantedthatwebelieveallsortsofdifferentkindsofpropositions:propositionsaboutethics,mathematics,aboutthesundriesofeverydaylife.Noone,presumably,willdenythatthesepropositionsconcernnotjustdifferentsubjects,butfundamentallydifferentsubjects.Andanyphilosopherwhowishestoclaimthatweshouldtreat

Wehaveputthreequestionstothepluralist.Wenowhavethreeanswers.

• Howdoweidentifythosepropertiesbyvirtueofwhichpropositionsaretrue?Answer:byseeingwhichpropertiesplaythetruth‐role,andhencehavethetruishfeatures.

• Howarethosepropertiesrelatedtotruth?Answer:Truthassuchisthepropertythathasthetruishfeaturesessentially.Buttruthcanbeimmanentindistinctproperties,propertiesthathavethetruishfeaturesaccidentally.

• Whatdetermineswhetheragivenpropositionhasoneofthosepropertiesratherthananother?Answer:twothings.First,thelogicalstructureofthepropositionandsecond,thesubjectmatteroftheproposition.
