YAf.{Y A AL-NAI;IWİ AND AL-GHAZALİ ON THE PROOFS OF
CREATION
Introduction
The purpose of this paper is to follow the traces of the sixth~century Ale
} xandrian Christian philosopher Ya(ıya al-Nabwf (John Philoponus) in the text of
Abii Ham id ai-Ghazalf (d. lll 1 ), chiefly in his Talıafut al-faliisifah (lncoherence
of the Philosophers) and to illustrate the extent to which Pbiloponus' main proofs
of creation were reproduced by al-GhazaU. It is wortb s tating that Philoponus was
known among the ancients with his arguments and counter arguments against the
philosophers mainly Proclus andAristotle on the issue ofthe etemity of the world
to which he devoted three works1• We know that these works were translated,
partially or totally, into Arabic2• SimiJarly, al-Ghazali was known in the Islamic
world for the same refutations of the argumeots provided by the philosophers who
taught that the world is etemaL lt is perhaps for this reason that it is often taken
for granted that aJ-GhazaiT reproduced Philoponus's proofs in his Tahiifut (wit
hout providing any serious evidence that Abü Ham id had indeed in his hand one
or more ofYaJ:ıya al-NaJ:ıwl's books). It is alsa wortb reminding that al-Baybaql
' stated in his Ta timmat Siwan al-lfikma that "the most of w hat is adduced by hıyjat
al-Islöm (the proof ofis lam) al-Ghazali, m ay Allah have mercy on him, in Tahafut
al-falösifah is a report of Yabyii al-Na/:ıwi's words"[my translation].3 Many sub
sequeot allusions have been made to this supposed influence ofYalJya al-NaJ:ıw1.4
An autbor may think that "it can be inferred that al-Ghazall read Philoponus in

Arabic translation from the fact that Maimonides, in the I 2th century, said that
John the Grammarian, meaning Philoponus, had been translated into Arabic'"';
for another: "since Proclus and Philoponus' books were widely known in the Isla
mic world, it is very natural that al-Ghazaii knew Proclus' proofs and Philoponus'
refutations",6 and yet for anotber there is no doubt that al-Ghazaii was "familiar
with Philoponus' works about creation of the world from nothing".7
The main question then is: to wbat extent was ai-Gbazali intluenced by
Yal:ıya ai-Nai:ıwi? And tberefore did he have direct access to Philoponus' work?
As far as I know, there is no single work exclusively devoted to this question.
Al-Gbazali's arguments for the eternity of the world as discussed in Talıöfut al
falösifah are well studied by many scholars. Michael Marmura, for example,
discusses the metapbysics underlying ai-Ghazall's arguments, but not in re la tion
with Philoponus' arguments. Only the work of H. Wolfson8 andA. H. David
son9 may be said to provide an outstanding study of the influence of John Phi
loponus' proofs of creation on Medieval Muslim and Jewish thinkers, among
wbom there is al-Ghazali. l will demonstrate, in my talk, that there is no evideoce
that ai-Ghazali drew directly from YaJ:ıya ai-Na}Jwi, but he certainly made use of
some of Philoponus' arguments as they were widely used by the Mutak.alJimün
and Falasifa within the lslamic tradition, in a slight different way. I will begin
by a glimpse at Philoponus' main arguments of creation in lslamic theology;
then I will move to some first evidence concerning Philoponus' flfst and second
arguments in ai-GhaziHi's text, and briefly focus on the contrast between Against
Proclus and Tahöfut; and finally I will discuss the striking similarities between
the two pbilosophers with respect to Philoponus' third argument and some other
issues actually reproduced not only by al-Ghazali but also by al-Mutakallimün
before him and those who came after.

ı. Pblloponus' arguments of creation in Islamic theology
There is a very extensive literature of refutations of the arguments of the
eternity of the world in the period that separates Yal)ya al-Nal)wT in the sixth
century and al-Ghazali in the eleventh century. Many works in Arabic were
i devoted to this topic, yet the most known philosophical book is ai-GhazalT's
· Tahafitt al-falösifah. It goes without saying that Philoponus' proofs of ere
} ation were well known to the theologians and philosophers in the Islami c ; , world, widely accepted by the Mutakallimün and the platooic philosophers
and refuted by the peripatetic pbilosophers. As it was stated above, Wolfson
and Davidson have already demonstrated the extensive use of Philoponus'
proofs by Muslim and Jewish theologians. I will focus on three main proofs of
creation provided by Philoponus and known to Muslims: the argument from
the fınitude of the power of the body, the argument from composition, and the
argument from time.
The argument from the finitude of the power of the body appears in his
De Contengencia Mundi10 in the following passage: "If the world is a fınite
body (an Aristotelian premise)[ ... ]and every power of every fınite body is finite
(another Aristotelian premise) [ ... ] it follows necessarily that the world(. .. ] is
,generated, it comes to be after it does not exist" (a non-Aristotelian conclusion)
.(my translation].11
The Christian peripatetic philosopher Ibn Siwar12 reformu
' lated it in the following syllogism(s): "every body is fınite, and the world is a
body, then the world is finite; and every finite body has a finite power, then its
power is finite; and the powers of eternal things are fınites, then the world is not
etemal"(my translation).13
1 O lt appears in the first pages of the fırst argument in Agalnst Proclus, repeated in Agaiııst
A.rlstatle and reproduced in De Conliııgentla Mımdi.
ll Philoponus, fi o/-da/ölat 'a/ö lıodaılı al'ö/onı (De Collfe11gencia Mımdi), in O. Troupeau, 'Un
Epitome Arabe du u De Contingentia Mımdt' de Jean Philopon,'op. cit., p. 79. He states:

13 Ibn Siwar, inA. Badawi, ol-ajlaüniyyôt a/-Mulıdatlıat 'indo al- 'orab, Kuwaiı: 1977, p. 246.
According to Ibn Siwar, this argument is more accepted than the kalarn argument because
it is based on essential things and the Mutakallimün's 'false' argument "is derived from ac
cidents". But Ibn Siwar was not aware that this arguınent too, ascribed to ai-Mutakallimün,
was presuınably derived from anoıher argument of Philoponus himself, i. e. the argument of
composition as Herben Davidson has well illustrated.
IV.OTIJRUM 363
The argument from composition appears in two forms "composition of matter
and form" 14 and "composition offinite parts". In the fust one, Philoponus confirms
that "the nature of matter is such tb at matter cannot retain any form indefinitely.
TI1erefore nothing composed of matter and form can be indestructible".15 Philopo
ous' second type of the argument from "composition offinite parts" was repeated in
rnany and different statements: 16 "that which consists of finite [parts] is finite".17
Philopoous' third argument which is much known in the kalarn tradition in
depeodently, or as part, of tbe argument from accidents, is the argument of the
impossibility of an infinite succession of time. Philoponus provided three inter
conoected forms of this argument: 18
A) The argument that the infinite cannot be traversed19; It is not possible to
14 The argument of composition of matter and form appears in Plıilponus 'AgoitısT Arislot/e and in De Contengencio Mundi in at least n.vo fonnulations: in the fırst he confınns that "the nanıre of matter is such that matter cannot retain any form indefinitely. Therefore, nothing composed of matter and form can be indestructible", and while demonsırıuing that the power of the universe is finite, Ya_tıyii aJ-Na.tıwi argues in the second: "The heavens are composite. Wbatever is composlte contains the grounds of its dissolution and therefore does not contain infinite power"; Simplicius, Commellloıy on tlıe Physics, p. 1331, Cf. H. Davidson, "John 'Philoponus asa Source ofMedievaJ lslamic and Jewish Proofs ofCreation", p. 362.
15 !dem. 16 lt appears in Agahıst Proclus as foUows: "tbe number of men or plan ts or of individuals of any
other kind that have come to be is finite, since each of them has had its existence in a finite time, it would al so be necessary for the whole of time i o be fınite; for w hat that w hi ch consists of fınite (parts) is finite", Agoinst Proc/us on the Eternity of tlıe World, 1-5, ıranslated by Michael Sh are, Duckworth: 2004, p. 24. In the second chapter 'maqiila' of De Comengencia
Mundi (fi lıadot al- 'ii/am) an argumenı from finite parts, and thus from generated parts, is provided as follows: all things that are composed from fınite parts are finite and thus they are generated. Philoponus presents it in the following syllogism: the world is composed from individuals that are generated and corrupıed and the duration of each ofthem is finite; then the
world is composed from durations of this finite individuals; and what is composed from things wlıicb each of lbem is finite in itself it is necessary fınite too; lben the world is not etemaL
17 Agoinst Proclus, 1-5, p. 24. 18 Which are repeated in many places of his aforementioned three trearises devoted to the que
tion. 11ıree supporting arguments that are very closer to each other could be discemed and at least two oftbem appears in al-IGncWs demonsıration on the crearion of the world.
19 lı reproduces an Aristotelian aıgumeot and reorients it against its original conclusion: everything that is infinite cannot be traversed. Aristotle, PITysics, VUJ, 8,263a, 7: "it is impossible to ıraverse distances intinite in number," meaning th.at an infi.nite number cannot be counted. And, in De
Coelo, I, 5, 272a, 3: 'ibe infinite cannot be traversed." In his Agoftıst Proclııs, Ya.tıyii ai-Na}.ıwi' affinns that the traversing of the infi.nite is impossible; i. e. to "counting it olfunit by unit [ ... ] even
364 900. VEFAT YIUNDA İMAM GAZZAIJ
traverse the i.nfin.ite "for the infinite is by its nature uotraverseable; otherwise it wo
uld not b~ infin.ite". He gave an example, wh.ich became weU laıown to Mustims, of "successive generations of [human] race, advancing individual by individual, have
desc~nded through an i.nfin.ite number of individuals to those that ex.ist oo\1/';20 tben,
. if it were infini te, the in:finite would become lraverseable, whicb is impossible. For the 1
. generations of the race have reached down to each of us, thenit is finite in number.21
} . b) The argument that an infinite cannot be increased22: the infinite is one
' and undivided; otherwise "many infini te things would be the same thing, which is
impossible. He gave many examples Like Socrates, the infini te number of species,
and the mavement of the spheres: "if the world had no beginning and the number
of men living before, say, Socrates was infinite; and those living from Socrates
until the present time have been added to it, there will be something greater than
the infınite, which is impossible".23
c) The third form of this argument, that an infınite cannot be multiplied, is
explained by the example of the unequal periods of the spheres' revolution. This
argument is very connected with the form er one. "If the motion of the heavens is
without a beginning" and the spheres "do not move with equal periods of revo
lution", then "it is necessary that the sphere of Satum" (which revolves once in
thirty years) "has rotated with an infinite number of revolutions, and the sphere
of Jupiter (which revolves once in twelve years) with nearly three times more
revolutions than that. The revolutions of the sun (which revolves once ina year)
will be thirty times greater in number than the ones of Satum, the revolutions of
the moon (which revolves ooce ina month) 360 times, and the revolutioos of the
sphere of the fixed stars (whicb revolves once in one day) more than ten thousand
times greater".24
The result is that the infinite will be multiplied, which is impos-
if the cowıter were everlasting" . "I mean the ttav~ing of the infini te by, as it were, cowıting it off unit by unit-is impossible, even if the cowıter were everlasting"; Against Proclus, 1-5, p. 24.
20 ldem.
21 "for the infini te is by i ts narure untraverseable ; otherwise it would not be infinite. So if the infinite is wıttaverseable, but successive generations of(buman] race, advancing individual by individual, have descended through an infinite number of individuals to those that ex.ist now, then the infini te has become traverseable, which is impossible. Therefore the number of earlier individuals is not infinite. for [if it were] the generations of the race would not have reacbed down to each of us, for it is impossible to traverse the infinite"; Against Proclus, 1-5, p. 24.
22 It reproduces also an Aristotelian principle: the infini te is undivided. 23 Agahıst Proclus, 1-5, pp. 24-25.
24 Pbiloponus, Agalnst Aristotle, translated by Christia.n Wildberg, Duckworth, 1987, p. I 46.

sible. Philoponus concludes that "It is not possible that the world is ungenerated
and without a beginning. For in that case the infini te will be traverseable and wiU
exist in actuality, and the infinite will necessarily always be growing and never
stop getting bigger than itself and roany times, not to say an infini te number of
times, infinity".25
There is no doubt that many of these arguments appear in ai-Mutakallimün
and al-Falasifa, accepted by the MutakaJlilun and al-K.indi (c. 800-870) and refu
ted by the peripatetic philosopbers. Al-.Kindi reproduces partially the fırst argu
ment but totally the second and the third ones.26 The argument from accidents,
as demonstrated by Davidson, is a reformulation of philoponus' argument from
composition of matter and form. Plıiloponus argument from the impossibility of
an infinite succession in time is largely reproduced as an independent proof or
as part of the argument from accidents. It is reproduced large Iy and in many for
mulatioos by the early and Iate Mutakallimün alike. AI-Nap,.am (d. 845) uses all
the three forms of this argument and it is this argument that al-khayy~t (d. 939)
deseribes as the best argument provided by al-Mutakallimün against etemaüsm.
The argument that an infinite cannot be increased is well known since al-Farabi
and fbn Sina as the method of app1ication. The argument from the impossibiliry
of an infini te number appears in lbn I:Iazm (d. 1 064) and al-JuwaynT (1 028-85) who was the fust to ineJude the third argument as fourt11.principle of the argument
from accidents.
Having said this, it is not wrong to expect that al-Ghazali as well will rep
roduce some of these arguments in his Tahöfut exclusively devoted to refute the
arguments provided by the philosophers.
2. Pbiloponus' arguments in al-Gbazali's text
That ai-GbazaiT never mentioned Yal;lya al-Nal)wi, nor any of his work, is
explicitly clear. He is not an exception in this matter; Philoponus is rarely cited in Arabic sources, in general, and when his name is cited, it is often confused witb
other Christians Ilke Yahya Ibo Adi. AI-Ghazlill's dealing with Philoponus' proofs
of creation is no exception, too.
25 Philoponus, Agailıst Proclus, 1-5, p. 25.

Proofs of Creation", presented at the 8th Intem~tional Colloquiwn of the SIHSPAI, London:
December 3-5,2010.

Indeed, Tbere is no textual ev idence that can support the cia im that Abü
Hamid ~as been directly influenced by Pbiloponus' work. In fact, the evidence provided by those who claim that al-Ghazii!T drew directly from Pbiloponus, al-~ayhaqi among the ancients, and recently Abderrahman Badawi and others, remains undefeoded. Although it is one of the strongest proofs, Philoponus' fırst argument does not defınitely appear among al-GhaziUi's arguments formulated against the philosophers. It seems that it was generally not known to al-Mutakllirnün whereas it is formulated by Ibn Siwar and known to the most ofperipatetic philosophers who refute it I ike lbn Rushd.27 The argument from composition is provided by al-GhazalT, like every Mutakallim, as part of the
kalarn argurnent from accidents, and it can be said that it is the same for the argurnent from the impossibility of an infini te time as we shall see later. Thus, from the two facts that the first argument is neitber adduced by al-Ghazali nor by any of the Muslim Mutakallimün, and that the second is present as a mere kalarn proof, we can deduce that the sources of ai-Ghazali's material, in his arguments formulated against the pbilosophers, are indeed the previous books
ofKalam.
Al-bayhaqi's view seems, as Shlomo Pines had already well noted, to be very exaggerated.28 In the same way, Badawi considers that all proofs provided
. by ai-Gbazali are a reformulation ofphiloponus' argument from Against Proc/us
. witb no substantial addition; "the difference consists just of formulations, con, cepts and the way of argumentation".29 Hence, ai-Gbazali's first argument, ac-
cording to him, reproduced Philoponus' third argument; the second is the same as Philoponus' fifth; and the third argument is equivalent to the second proof in Against Proclus. Tben Badawi adds that it goes for all al-Gbazali's arguments on the etemity of the world, time and mavement that have the ir equivalents in Against Proclus mainly the seventb, the eighth and the ninth proofs.30 However,
27 However, al- GhazzlilT, !ike al-K.indi and al-Mutakallimlin, argues from the finitude of the
body of the universe.

Badawi does not provide any seri o us comparison of passages, formulations and
exampl~s of the two philosophers.
In opposition to what is suggested by BadawT, it seems that al-Ghazali's ar
gumeots of creatioo have oothing to do, in general, with Philoponus' book Against
P1·oclus-except for some general similarities due, on the one hand, to the fact that
Philoponus' argumeots were widely usedin lslamic theology as stated above, and
on the other, to their similar religious and philosophical background (i. e. Monot
heism and Neo-Platonism).
In the third argument, Proclus asserts that if a cause (the creator) is actual,
"that which is caused willlikewise be actual"; Philoponus, armed with the Aris
totelian canception ofactuality and potentiality, observes how Proclus "does not
specify with refereoce to which sense of actuality he is hypothesising that the
creator is an actual creator"/1 However, al-Ghazali's critique of the proof of the
philosophers, especially based on the ash'arite canception of the etemal will,
defends, thus, the idea that "the world was an object of the etemal will at the
time when it actualized".32 In this context abü bamid reproduces the third form
of Philoponus' argument from the impossibility of an infini te sucession in time.
Nevertheless, neither the problem of the etemal will nor the third form of Phi
loponus' third argurnent, as presented by al-Ghazali, are present in Philoponus

third argument nor in any other argument provided in Against Proclus. lnste
ad, the influence of Against Aristat/e on al-Ghazali's fust argumeot is indirectly
observed?3
fJ-Gbaziili's second argument that "God is prior to the world in essence not
1 in time", in fact, does not reproduce Philoponus' proof as it is provided in his
·. refutation of the Proclus fıfth proof from time in spite of the appareot similarity
J betwe~n the two arguments. the argument refuted is likely the same, and !ike
~ Philoponus, ai-Ghazall.uses the same method but not the same arguments nor the
same concepts. In addition, al-Gbazall's argumentation seems to be more general;
it discusses this argument as the argument of the philosophers in generaiJ.4 where
as Philoponus dea ls exclusively with Proclus argument, sometimes word by word,··
referring to Plato's Timaeus and its interpretations.
Finally, while Proclus' second argument deals wiıh forms as etemal world
patterns w hi cb necessitate that a copyas well should also be etemal,3s al-Ghaziilr's
third argument from the possibility suggests that if the world "is supposed to have
existed for ever, it will not be an originated thing. Accordingly, the actuality will
not be commeosurate with the possiblity, but incongruent with it''.36 Despite the
broad similarity with Proclus second argument (pattemlcopy and actuallity/possi
biliy), al-Ghaziiii's objection is very different from Yahya al-NahwT's, not only in
'"formulations, concepts and way of argumentation" as suggested by BadawT but
; aıso in the body of the argument itself.
33 ai-Ohaz.zalr refutes Aristotle and the Muslim Aristotelians, but not directly Proclus. Maııy
themes and arguments caıı be located in the fragıneniS preserved from Agahıst Arlstotle: the
arguınent from the revolution of the spberes; that the celesıial movement isa natural movement; the issue of the void; ... ete .. In addition, ai-Ghazzalrs argument, that the number of
people who suppon the idea that the world was generared is greater than the number of those
who support i ts etemity, reminds us of as imilar statement in Philoponus Agamst Arostotle's.
34 lt should be noted that ai-Ghazzaır does not mention Proclus among the philosophers conce -ned directely by his refutation.
35 For Proclus, if the pattem of the world were etemal, the world would necessary be etemal. Proclus'
argument is based on aııalogy, the pattem aııd the copy presupposes each other, aııd if one of them
is etemal the other would necessaıy be etemal too. Philoponus aıgues that "even though the Forms
are eıemal, it is not at all necessary that the ir copies (I mean the perceptible substaııces) should also
always exist[ ... ] ifthere isa copy, a pattem must exist; but even ifa pattem exits, though not [me
rely] asa pattem but because it is also a substaııce, it is not necessary for a copy to exist as well"

However, in wbat concems the argument of the impossibility of an infinite
number, besides some other issues as we shaU see, the similarities seem to be
striking between the two philosophers.
3. al-Ghazali's argumeot from the impossibility of ao infini te by succession
The most known argument to al-Mutakalimun and al-Ghazali is the ar
gument from the impossibility of an infinite succession of time. Al-Ghazali
reproduces the second and the third form of this argument and provides two
of philoponus' examples: the spheres' revolutions and the infınite number
of souls.
ln the flfst objecrion to the first argument, al-Ghazali formulated Philoponus
third argument in the foUowing passage:
"How will you disprove your opponents if they say: "The etemity of the
world is impossible. For it leads to the affinnation of spherical revolurions which
are infinite in number, and consist of innumerable un.its. The fact is that these
revolutions can be divided into one-sixth, or one-fourth, or a half. For instance,
the sphere of the Sun completes one revolution in one year, w bile that of Satum
makes one in thirty years. Therefore, the revolurions of Saturo are one-tbirtietb
of those of the Sun. And the revolutions of Jupiter are ooe-twelfth of those of the
Sun, for Jupiter completes one revolution in twelve years"? You maintain that, in spite of the fact that the revolutions ofSatum are one-thirtieth of the Sun, they are
equally infınite. Nay, you would assert that the revolutioos of the S tellar Sphere,
each ofwbich takes thirty-six thousand years, are as infinite as the East-West mo
vement of the Sun, w hi ch takes only a day and ni gbt. If someone says that this is
an impossible thing, and that its impossibility is self-evideot, how will you silence
his criticism?".37
1n fact, al-Ghazali reproduced the same example provided by Philopoous in his third form of the argumeot from time and movemeot, ina slight different way.
Since the spheres do not revolve at equal speed and iftheir mavement has no be
ginning, it necessarily follows that an infini te wiU be multiplied, i.e, for instance,
the revolution of the spbere of the fixed stars (which revolves once in one day) has
rotated more than ten thousaod times greater than Saturo (wbicb revolves once in
thirty years), as have shown above.

Indeed, similarities are striking betweea the two formulatioos of the same
argumeot of the impossibility of ao infınite by successioa based upoo the exaınple
of the revorution of the celestial spheres. Both Philopoaus and al-Ghazali were on
the position of refuting the idea of the eternity of the world. Many elemeats and
premises ofPbilopoous argument are present in al-Ghazali's argument. They used
the same Aristotelian premisses and arrived at the same non-Aristotelian conclusi
~n. Except the moon, al-Ghazali mentions all the other four spheres (Satum, Sun, (
Jupiter iınd the fix.ed stars) but with a different order. Moreover, both of them,
independently of each other, argue that an infini te movement is impossible, for it
leads "to the affinnation of spbericaJ revolutions which are infini te io number, and
consist of innumerable units", and, therefore, to an impossible consequen·ce that
an infinite is greater than another.
The second form of the argument is from addition, the infınite cannot be
increased; al-Gbazali provides the exaınple of an iofinite number of souls; be
demonstrates:
"if you assert that the past eveats are existing neither at preseat nor in any
:>ther state, and that the non-existeat cannot be deseribed as limited or unlimited,
then you will have to take a similar view of the human souJs which have departed
from bodies. For, according to you, they do not perish. And the number of souls
~xisting after their separation from the body is ir~finite. A sperm is continually ge
ıerated from a man, and a man from a sperm, and so on iadefınitely. And this soul
:s by number different from the soul of those who died before, or after, or togetber
.vith, this man. If all the souls were by species one, then, according to you, there
Nould exist at any time an unlimited number of souls".38
And further, he adds:
" if we suppose that every day such an imper~shable thing cam e in to existence
o last forever, obviously, by this time, there should have accumulated ao i.nfinite

number of such beings. For even if a circular were transitory, stili the appearance
in it of an everlasting being should not be impossible. So by this supposition the
diffıculty is reinforced. It is irrelevant here whether this everlasting thing is the
soul of aman, or ajin, or a devi!, or an angel, oranother being you may suppose.
For the difficulty will arise, wbatever point of view they may have taken. And it
will arise because they have posited spherical revolutions which are infınite in number".39

There is no doubt that this example is ultimately derived from Pbiloponus.
Nevertheles, the presence ofthese two examples in al-Gbazali does not mean that
he quotes directly from Against Aristotle. Four remarks are worthy of considera
tion here: First, al-Ghazau reforrnuJated an argument which was widely used and
reproduced in rnany formuJations by the Muslim theologians and philosophers.
It was already stated that it was reformulated by many Muslim theologians like
al-Na.ı?am, Ibn ijazın, and reproduced by ·aı-Juwayni as a fourth principle of the
kalarn prooffrom accidents. Second, al-Ghazali does not produce the full third ar
gurnent as in Philoponus: the first form of this argument that the iniinite cannot be
traversed does not appear in Tahiifut al-falasifah n or elsewhere in the work of al
Ghazali. Unlike al-Na.ııam for example, al-Ghazali produces only the second and
the third form. Furthermore, he does not clearly and totally reproduce these two
forrns, but only some Philoponus' examples explaining this argument. And the
two same examples are provided by al-GhazaiT, as we have shown, in a different
formulation. Third, al-Ghazali cl early reproduced the example of the unequal re
volution of the sp bere and the example of infini te souls in order to demonstrate the
impossibility of an infinite by succession in time. However, while it is clear that
the fırst is derived ultimately from Philoponus, the second is not. The argument
from the number of souls seems to be a Muslim variation of Philoponus' argu
ment. Instead of the infınite number ofraces (men, fathers, horses and dogs), the
Muslims preferred to use the infini te number of souls just as they preferred the use
of the prophet's bej ra (migration from Mekka to Medina) instead of the example
of Socrates. The second example is derived from a very laıown argument used by
39 Talıöfut al-falasifalı (Jncolıerence af tlıe Plıilosoplıers), English translation, p. 95; Bouyges' edition, p. 142. He states:

al-FarabT, Ibo s-ına and by ai-Mutakallimiin; it is called the method ofapplication.40
Fourth, ai-JuwaynT is strongly thougbt to be the source of ai-Gha.zali's two argu
meots. It seems that these arguments are based on ai-Juwa~'s proof from the
impos~ibility of infı.nite revolutions (among other supposed kalarn sources) but
rot directly on Philoponus' text. The formulation ofthese two argumeots (examp
les), chiefly the second one, reminds us ofai-JuwanT's statement41 and even ofbis
~ay of ıırgumentation (from the spbere revolution); ai-GhazaiT's formulation and
words are closer to al-Juwayni's statement than to Philoponus's.~2
However, ai-Gbazalı-·s formulation of the argument is stili clearer and more
complete compared with al-Juwayni's. It is worth noting bere that the second
and the third fonn of the argumeot from the impossibility of an infini te successi
on, unlike ai-GhazaiT, appear clearly, with the same examples, in fbn H.azm who
"contends that over an eternity the number of men, the number of horses and
the total of the two would be infini te, leading once again to the absurdity of one
infınite's being larger than another".~3 However, Like al-Na..?+am, al-Kindi, fbn
H.azm, al-Juwayni and al-Shabrastaıü, al-Ghazali argues from the finitude ofbody
(not the power ofbody) to the finitude oftimejust as in ai-KindT. He states: "what
bad happened to tbese pbilosophers who deny, on the one hand, the possibility of
bodies arraoged above one another in space ad infinitum: but admit, on the other
band, the possibility ofbeing existing before one another in time ad infinitum ı is
~ot this an arbitrary, groundless and unconvincing position?" . .ı.ı What Pbiloponus
deseribes as "the most scientific explanation of these things" remains the follo
wing: s ince the infınite (in magnitude or in number) cannot exist in actuality as
40 Philoponus gave the exampıe of the number of souıs but ina differenı way: God knows prevousıy the number of so u ıs that will paıticipate in bodiıy life in the furure as well as the number ofheavens' revoıutions.

proved by Aristotle and "agreed to be so by all witbout exception", "it is absolu
tely necessary that the number ofthings be fınite. And this being so, it is ridicuJo
us to ask why more things do not exist".4s
On the other band, there are other similarities that can be illustrated. Accor
ding to Philoponus as well as to al-Ghazalr, God "brings all things ioto existence
by pure thought al one whenever He wills it. And since God passesses the concepts
ofthings neither more nor less in consequence oftheir being or not being, it would
follow that in God's case capacity and activity in no way differ.''46 For al-Ghazili
too "activity and capacity are the same and one".47 However while Philoponus
argues from God's knowledge, al-Gbazali demonstrates from God's etemal will.
Both ai-Ghazali and Ya.l).ya al-Na.l).wi point out clearly that God "brings all tbings
into being just by willing them" and they both agree that "no alteration will be
apprehended in God as a result of his producing at one time and not producing a
thing or does not produce it[ ... ]The will of God is therefore one and simple and
is always the same and unchanging."48 Stili, there aresome differences bet:ween
the two philosophers. It is true that they both assert that "there is no necessity that
a thing should exist the moment God thinks of it'',49
yet in what concems Phi
loponus, the world was present in God's foreknowledge, not really in the etemal
will of God because "Will brings all things into existence at the instant He wills
them".$0 It is worth noting bere that philoponus' view is closer to the view of the
Mu'atazilites than to the ach'arites like al-Ghazali who is not just refuting the
view of the philosophers without iovolving his ach'arism, as he claims, but he
indeed defends his acb'arite canception of creation that the world was created at
a time it was created by God's eternal will.
Conc.lusion
Finally, the similarities between the two philosopbers do not stand as eviden
ce that al-Ghazali had read Pbiloponus' work. Al-GhazaJI was indeed influenced
by Yal)ya al-Nal)wi, but indirectly. He does not seem at all to have bad direct
access to Philoponus' text. It is obvious that we cannot infer from the fact that

Philoponus was translated into Arabic that al-Ghazaii formulated his arguments against the philosophers on the issue of the eteruty of the world as derived from YaJ:ıya al-NaJ:ıwi. In fact, Philoponus' third argument was widely reproduced in many_foı:mulations by the Mutakallimün, among whom we find al-Ghazali him-1self, and there is no indication that al-GhazalT drew directly from Against Proclus
.. or from any other work ofPhilponus.51
