Theseventeenthdiscussionofal-Ghazālī’sIncoherenceofthePhilosophershasbecome
famousforitscriticismofcausality.WhenSolomonMunk,thefirstWesternanalystofthe
Incoherence,readtheseventeenthdiscussion,heunderstoodal-Ghazālīassayingthat
“thephilosophers’theoryofcausalityisfalse,andthattheyarenotrightwhentheydeny
thatthingscanhappencontrarytowhattheycallthelawofnatureandcontrarytowhat

simplydeniedtheexistenceofcausalityintheoutsideworld.Forstudentsofphilosophy
andtheology,theseventeenthdiscussionoftheIncoherencehasbecomealocus

inAvicenna’scosmologyarecausalintermediariesbetweenGodandthesublunar
sphere.Foreventsinthesublunarsphere,al-Ghazālīnamestheactiveintellectasoneof
theircauses.Theintellectisnamedasthe“giverofforms”(wāhibal-ṣuwar)inthesphere
ofgenerationandcorruption.HereintheFirstPosition,al-Ghazālīacceptsthatthe“giver

thosewhosearchdiligentlyfortruthamongthephilosophers(muḥaqqiqūhum),al-Ghazālī
says.
AfterfindingcommongroundwiththeAvicennans,al-Ghazālīattackstheadversary’s

doesnotmeanthatitexiststhrough(bi-)it.27Concurrenteventsneednotbeconnected
withoneanother;andeveniftheyare,theconnectionmaybemuchmorecomplexthan
whatwewitness.
Byusingthisargument,al-GhazālīintroducessomeconfusionintothisFirstPosition.
Apparently,al-Ghazālīintendstoargueagainstthepositionthatfireistheabsolute
efficientcauseofthecotton’sburning,apointatwhichherightfullyclaimsagreementwith
theAvicennanfalāsifa.Butbyreferringtotheepistemologicalobjectionthatobservation

beenunderstoodasbeingmoreradical.Heseemstoobjectnotonlytothosewhoteach
thereare(absolute)efficientcausesotherthanGod,butalsotothosewhoteachthat
causeshaveefficacyontheireffects.
Thisisnotwheretheconfusionends.Whilearguingthatfirecannotbetheonlyefficient
causeforthecotton’scombustion,al-Ghazālībringsaverybriefsideargument:“Asfor
thefire,itisaninanimatebeing(jamād)andithasnoaction(fiʿl).” 28Hereal-Ghazālī
refersbacktoanobjectionhemadeinthethirddiscussionintheIncoherenceaboutwhat
canbecalledafāʿil,or,anagent(p.153) oranefficientcause.Motivatedby
considerationsthatwillbecomeclearlaterduringthisstudy,al-Ghazālīsimplyrejectsthe
terminologyofthefalāsifa—theAvicennansaswellasanyothergroup.ForAvicenna,for
instance,thewordfāʿilmerelydescribestheefficientcause:itisthethingthatgives
existencetoanotherthing.29InthethirddiscussionoftheIncoherence,al-Ghazālīrejects
thatusageonthegroundsthataccordingtocommonunderstanding,thewordfāʿil
describestheoriginatorofanact—al-Ghazālīusesapronounthatreferstoapersonand
notathing—whohasawill,haschosentheactfreely,andhasknowledgeofwhatis

showsafundamentaldisagreementbetweenhimandAvicennaaboutthemeaningofthe
wordfāʿil.Foral-Ghazālī,itmeans“voluntaryagent”;forAvicenna,simply“efficient
cause.”Intheseventeenthdiscussion,al-Ghazālīthrowsinthisearlierargumentwithout
furtherpursuingthepoint.Althoughprimarilydirectedagainstanonsecondary
understandingofcausality,thesentenceisultimatelyalsodirectedagainstAvicenna’s
particularunderstandingofsecondarycausality.InthecontextoftheFirstPositionhere,
whichdoesnotrepresentAvicenna’sviewoncausality,thesentenceissomewhat

interpreters.31

The Seventeenth Discussion of The Incoherence of the Philosophers
arguesthatallthingshaveacertainpredisposition(istiʿdād)thatdetermineshowthey
reacttootherthings.Thispredispositionispartofthething’snature(ṭabʿ).32Because
thesenaturescannotchange,thethingsreactnecessarilytogivencircumstances.Cotton,
forinstance,necessarilyburnswhenitcomesincontactwithfire.Here,al-Ghazālī
paraphrasesthepositionofAvicennaandotherAristotelians.Thephilosopherofthe
SecondPositionteachessecondarycausality;hebelievesinthenecessityofcausal
connectionandintheexistenceofnatures(ṭabāʾiʿ).
Al-Ghazālīdivideshisresponsetothispositionintotwo“approaches”(singl.maslak).The
FirstApproachcountersthisphilosophicalpositionwiththatofaconsistentoccasionalist.
Al-Ghazālīaskshisphilosopher-opponenttoconsiderthatnothinginthisworldfollowsits

Thephilosophersagree,al-Ghazālīsays,thatprophetshavebeengiventheabilitytolook

Avicenna’sviewofthemodalitiesisnotsignificantlydifferentfromthestatisticalmodelof

IntheWesternphilosophicaltradition,inwhichAvicennabecameaninfluentialcontributor

The Seventeenth Discussion of The Incoherence of the Philosophers
Ofcourse,aworldinwhichfiredoesnotcausecombustionincottonwouldberadically
differentfromtheoneinwhichwelive.Achangeinasinglecausalconnectionwouldlikely
implythatmanyotherswouldalsochange.Still,suchaworldcanbeconceivedinour
minds,whichmeansitisapossibleworld.God,however,didnotchoosetocreatesuch
analternativepossibleworld.Hechosetocreatethisworldamongalternatives.
Intheinitialsentenceoftheseventeenthdiscussion,al-Ghazālīarguesagainsttwotypes
ofadversaries.First,hearguesagainstthosewhoholdthatacausalconnectionis
necessarybyitself.Thisgroupincludespeoplewhoclaimthatanygivenproximate
efficientcauseisanindependentefficientcause(fāʿil)ofitseffect.Thisgroupalsoincludes
somenaturalphilosopherswhorejectsecondarycausalityaswellastheMuʿtazilites,who
arguethathumanscreatetheiractionsandtheimmediateeffectsofthem.Al-Ghazālī,
however,makesaclear(p.173) distinctionbetweentheteachingsoftheMuʿtaziliteand
thoseoftheAvicennanfalāsifa.141 TheAvicennanfalāsifaarethesecondgroupof
adversariesintheseventeenthdiscussion.Althoughal-Ghazālīdoesnotargueagainstthe
ideaofsecondarycausalityinAvicenna,hedoesrejectAvicenna’steachingthatthe
connectioncannotbeanydifferentfromwhatitis.Beingcontingentbyitself,accordingto
Avicenna,theconnectionbetweencauseandeffectisnecessaryonaccountofsomething
else,namely,God’snature.God’snaturecannotbeconceivedanydifferentlyfromwhatit
is.ForAvicenna,therecanbenoworldalternativetotheonethatexists.
Intheinitialstatementoftheseventeenthdiscussion,al-Ghazālīalsoclaimsthat“the
connection[betweencauseandeffect]isduetothepriordecision(taqdīr)ofGod.” 142
WhenheobjectstoAvicennaandstatesthattheseconnectionsarenotnecessary,alGhazālīwishestoexpressthatGodcouldhavechosentocreateanalternativeworldin
whichthecausalconnectionsaredifferentfromthoseofthisworld.Al-Ghazālīupholds
thecontingencyoftheworldagainstthenecessitarianismofAvicenna.Foral-Ghazālī,this
worldisthecontingenteffectofGod’sfreewillandHisdeliberatechoicebetween
alternativeworlds.
WhilerejectingthisnecessitarianelementinAvicenna’scosmology,al-Ghazālīdoesnot
objecttothephilosopher’sconceptofsecondarycausality.OfthetwopillarsinAvicenna’s
cosmology—secondarycausalityandnecessitarianism—al-Ghazālīrejectsonlythelatter.
IntheFirstPositionoftheseventeenthdiscussion,al-Ghazālīusessecondarycausalityto
refutetheviewthatproximatecausesareindependentefficientcauses.IntheSecond
Position,heofferstwoalternativeexplanations(“approaches”)ofpropheticalmiracles,the
firstbasedonoccasionalism,thesecond,onsecondarycausalityandtheexistenceof
natures(ṭabāʾiʿ).Inallthisdiscussion,al-GhazālīsaysnothingaboutwhetherGodactually

miracle.Foral-Ghazālī,theconnectionbetweenthecauseanditseffectiscontingent
evenifGodneverchangesHishabits.ThesolepossibilityofHisbreakingHishabit—that
wecouldconceiveofGodbreakingHishabit—orjustthepossibilitythatHecouldhave
