Fifth,doesKantregardanypartofspeculativemetaphysicsasworthsaving? And,ifso,howdoesthissalutarypartoftheenterprisedifferfromthepartsto bediscarded?
Toanswertheseandrelatedquestions,Ihavefounditnecessarytoattempta studyoftheTranscendentalDialecticasawhole.The ‘Dialectic’,asthispartofthe workiscolloquiallyknown,accountsforsometwo fifthsofKant’smasterwork.Init weareoffered among many otherthings asearchingexaminationofthedogmatic speculativemetaphysicsofcertainofthecriticalKant’smodernpredecessors amongthem,mostnotably:Descartes,Leibniz,Wolff,Mendelssohn,and(less explicitly)Kant’searlier ‘pre-critical’ self.⁴ Themetaphysicsofthesephilosophers qualifiesas dogmatic,inKant’sview,becauseithastenstoitsattemptedproofs withoutundertakingapreparatoryexaminationofthemind’scapacitiesand powers.⁵ Itis speculative becauseitrestson ‘theoretical’ grounds,suchasthe PrincipleofSufficientReason,ratherthan ‘practical’ grounds,suchasthefactthat westandundermoralobligations.⁶
InKant’sview,theultimategoalofdogmaticspeculativemetaphysicsisto provecertain ‘cardinalpropositions’ ofpurereason including,pre-eminently, theexistenceofGod,ontheonehand,andthenaturalimmortalityofthehuman therelevantantinomy,thenthepairwouldbe: ‘Thethesisandantithesisof A arecontradictories’ and ‘Thethesisandantithesisof A areeachsupportedbysoundarguments.’ Theantinomialparadoxwould beresolvedifonecouldshoweitherorbothofthesepropositionstobefalse.Aswewillsee,Kantinfact supposesthathecanshowbothtobefalse.
⁴ Moreaccurately,intheDialecticweareofferedatreatmentofsomebutnotallofthedogmatic viewsofthesephilosophers.Leibniz’scommitmenttotheidentityofindiscernibles,forexample, receivesitscritiqueintheappendixon ‘Theamphibolyofconceptsofreflection’,whichimmediately precedestheTranscendentalDialectic.InthisearliersectionKant’scritiqueisdirectednottowardsthe facultyofreasonanditspurportedproducts asittendstobeintheDialectic butrathertowards certainconclusionsdrawnfrom ‘mereactsofreflection’ (A278/B335).Kanthasinmindcertainerrors thatoccurintheperformanceof ‘transcendentalreflection’:thepracticeofassigningrepresentationsto theirappropriatecognitivefaculties(compare9:73).
⁵ B xxxv;8:226;9:83–4.Kantinsiststhatthereisnothing initself problematicaboutseekingstrict proofsfromprinciplesknownapriori theso-called ‘dogmaticprocedure’ ofreason(B xxxv).Buthe believesthatwemustusethisprocedureonlywithinitsproperdomains.
⁶ Aswewillsee,however,theword ‘speculative’ isnotalwayspejorativeforKant(compareA xxi). Inparticular,whenitmodifies ‘ reason ’,itcanmeanmerely ‘theoretical’ asopposedto ‘practical’ (compareB xliii).
soul,ontheother.⁷ Theobjects whetheractualormerelyputative withwhich thismetaphysicsdealsfallintotwooverlappinggroups.Ontheonehand,there arethethree ‘supersensibleobjects’ connectedwithKant’sdoctrineofpractical faith,namely,God,immortality,andfreedom.⁸ Ontheother,therearetheobjects studiedbythethreebranchesofWolffian ‘special’ metaphysics.Thesearethe intentional or,asKantputsit, ‘imagined’—objectsofthe ‘TranscendentalIdeas’ of:theworld(conceivedofasanabsolutetotalityofobjectsofsense);thesoul (conceivedofasasimplesubstance);andGod(conceivedofasthesupreme intelligence).⁹ Aswewillsee,Kanttakesadifferentepistemicattitudetowards theexistenceofeachoftheseobjects:herejectsthe firstasnon-existent,isagnostic abouttheexistenceofthesecond,andbelievesinthethird thoughonthislast pointheisnot,Ifear,entirelyconsistent.¹⁰ Inallthreecases,however,heinsists thatwecanhavenotheoretically-grounded knowledge [Wissen]oftheseobjects, andhedisdains,asahallmarkofdogmatism,theambitiontoacquireit.¹¹
Thisambition alongwithitscharacteristicattitudesandallegedproducts constitutesthemaintargetofKant’scritiqueofspeculativemetaphysicsinthe Dialectic,and,perhapsunsurprisingly,my firstandmostbasicgoalwillbeto scrutinizethedetailsofthatcritique.¹²ButIhave,inaddition,anumberofless predictablegoals,whichIwouldliketospendamomentoutlining.
⁷ SeeR5637(18:273)andA741–2/B669–70.Thischoiceof ‘cardinalpropositions’ isentirely appropriatebecauseDescartesinhis DedicatoryLettertotheSorbonne describesGodandthesoulas twotopicsconcerningwhichdemonstrativeproofscanandshouldbeprovidedwiththeaidof philosophyratherthantheology(AT VII,1; CSM II,3).Kantoccasionallycharacterizesthefreedom ofthewillandtheidealityofspaceandtimeascardinalpropositionsofmetaphysics,thoughwhenhe doessoheisexpressinghisownviewoftheappropriatetargetpropositionsofmetaphysicsratherthan thatofhisopponents(seeA799–800/B828,R6349,andR6353).
⁸ At5:469Kantcallsthesesupersensibleobjects ‘ res fidei’ (‘mattersoffaith’)(seealso20:350, R6317,and20:295).Immortality,beinga ‘futurelife<vitafutura>’ thatfollowsnecessarilyfromthe natureofthesoul(28:763),isaphaseoftemporalexistence(compare20:298).Accordingly,Kant’ s reasonfordeemingit ‘supersensible’ cannotbethatitisatemporal.Thereasonisratherthatitisnota possibleobjectofexperience(4:477;29:945).Thisissofortworeasons.First,thedaywillnevercome whenIamableempiricallytoverifymyunendingexistence;second,forKant,immortalityrequiresthe post-mortem necessary enduranceofthesoul afeaturethatcannot,heinsists,bereadoffofthe deliverancesofthesenses.Incidentally,thefactthatimmortalityisaphaseoftemporalexistence suggeststhatKantdoesnotconceiveofthesupersensibleobjectsthataremattersoffaithas ingeneral thingsinthemselves;forthingsinthemselvesareineverycaseatemporal thoughhecertainly conceivesofsomeoftheminthisway.

Ifthisisright,thenKant’sbugbearintheDialecticisnotspeculativeor theoreticalmetaphysicspersebutrathersomethingmorespecific.Whatexactly? Aprimecandidate,Iwouldsuggest,is dogmatism understoodasanunrealisticallyinflatedestimationofhowmuchonecan know ontheoreticalgroundsalone (alongwiththeprojectoftryingtofulfilthisexpectation).¹⁷ InKant’sview, dogmatismcantaketheformeitherofdogmaticspeculativemetaphysicsorofa somewhatparadoxicallylabelled ‘dogmatic scepticism’—thepragmaticallyselfdefeatingattempttoestablishwithcertaintythatnothingiscertain,anaspiration thatKantassociates,somewhatfrowningly,withAcademicscepticism.¹⁸
ThescepticismofPyrrho,bycontrast,hetreatsasworthyofrespect.The Pyrrhonian ‘critical’ or ‘problematic’ sceptic,hesupposes,doubtsonlyinorder toeventuallygaincertainty(24:214).KantplainlyhasgreatsympathyforPyrrho, though,equallyplainly, his Pyrrhoisnottobeconfusedwiththefounderof traditionalPyrrhonism.Indeed,Kantregardsasacompletenon-starterthe positionusuallytermed ‘Pyrrhonism’—namely,thephilosophythatadvocates thebalancingofclaims,followedbythesuspensionofjudgment,withtheaim ofattaining tranquillity.Herejectsthisapproachmainlybecausehesupposesthat oncertainquestionstheresimplyisnopermittedignorance hencenoprospect
pointthatKantarguesforadoctrinalbeliefintheafterlife.SeeAndrewChignell, ‘BeliefinKant’ , PhilosophicalReview,116(3)(2007),323–60.
¹⁶ Kanttakes ‘metaphysics’—whenthetermisusedforsomethingdistinctfromanaturalpredisposition(B22) tohaveatleastthreemeanings(A843/B869).Initswidestsense,thetermconnotes thephilosophyofpurereason.Thisdividesintocritique(orpropaedeutic),ontheonehand,andthe systemofpurereasonontheother,thelatterqualifyingas ‘metaphysics’ inasecond,narrowersense. Thesystemofpurereasoninturndividesintothespeculativeuseofpurereason(or ‘metaphysicsof nature’),ontheonehand,andthepracticaluseofreason(or ‘metaphysicsofmorals’),ontheother. Kantsupposesthattheterm ‘metaphysics’ isusuallyusedforthemetaphysicsofnature.Sincedoctrinal beliefsareproductsofthespeculativeortheoreticaluseofpurereason,itisplausibletosupposethat they ortheargumentsjustifyingthematleast countasbelonging somewhatparadoxicallygiven theircontent tothemetaphysicsofnature.

Oneofthemorecatchyslogansofthe first Critique isKant’sconfessionthathe founditnecessaryto ‘deny’—orperhaps ‘annul’ [aufheben]—‘knowledge[Wissen] inordertomakeroomforfaith[Glaube]’ (B xxx).²¹Tantalizingly,heleavesthis signatureclaimsomewhatunder-elaborated.Whyexactly onewantstoknow shouldhavingknowledgeofcertainmatters oratleasttheambitiontoacquire it threaten,intheabsenceofthecriticalphilosophy,toleavenoroomforfaith?
