Analytical Arguments
Cosmological Arguments
The cosmological argument was first introduced by Aristotle and later refined in western Europe by the celebrated Christian theologian, Thomas Aquinas (d.1274 CE). In the Islamic tradition, it was adopted by Al-Kindi, and Ibn Rushd (Averroes). The argument has several forms, the basic first-cause argument runs as follows. Every event must have a cause, and each cause must in turn have its own cause, and so forth. Hence, there must either be an infinite regress of causes or there must be a starting point or first cause. Aquinas and Al-Kindi reject the notion of an infinite regress and insist that there must be a first cause, and the first cause must be God, the only uncaused being.
Another form of this argument is based on the concept of a prime-mover. This is the Aristotelian form of the argument also propounded by Averroes. The premise being that, every motion must be caused by another motion, and the earlier motion must in turn be a result of another motion and so on. The conclusion thus follows that there must be an initial prime-mover, a mover that could cause motion without any other mover.
Two kinds of Islamic perspectives may be considered with regard to the cosmological argument. A positive Aristotelian response strongly supporting the argument and a negative response which is quite critical of it. Among the Aristotelian thinkers are Al-Kindi, and Averroes. Al-Ghazzali and Iqbal maybe seen as being in opposition to this sort of an argument.
Al-Kindi is one of the many major and first Islamic philosophers who attempt to introduce an argument for the existence of God based upon purely empirical premises. In fact, his chief contribution is the cosmological argument (dalil al-huduth) for the existence of God, in his On First Philosophy [Nasr, p. 168]. He presents four different versions of this argument, all are variation of the cosmological argument which require a cause.
One of the arguments revolves around the principle of determination (tarjjih), that is prior to the existence of the universe it was equally likely for it to exist or not to exist. The fact that it exists, implies that it required a determining principle which would cause its existence to prevail over nonexistence. This principle of determination is God [Kindi, p. 58].
This is similar to Leibniz's principle of sufficient reason [Russell, p. 568; Cassirer, p. 73]. Leibniz argues that everything in the world is contingent: that it may or may not have existed. Something will not exist unless there is a reason for its existence. This rests on his premise that the actual world is the best possible world, as such we can account for everything in it as being there for a specific reason. But the universe as a whole, requires a further reason for existence, and that reason for Liebniz is God.
It should be noted that Liebniz' theory of the best possible world is flawed. We can conceive of a better world than any possible 'best' world that can be created. An additional unit of pleasure or goodness can be added to it to make it better. Therefore, it seems implausible to think that a 'best possible world' could ever exist.
There are difficulties with this kind of an account of the universe. It seems to lead to the conclusion that all truths are necessary. That is, if everything exists because the reasons for its existence supersede the reasons for it nonexistence, then it will necessarily exist. Everything and anything with a sufficient reason to exist will exist. Therefore, the universe and everything in it, must necessarily exist. Since, the superiority of its potential existence over its nonexistence provides the required determining principle (of Kindi) or sufficient reason (of Liebniz), for it to exist.
It appears now that the bringing into being of the universe is not contingent upon the will of God, rather it is something that is as necessary as the existence of God Himself. This seems implausible. In response Liebniz argues that its existence is only theoretically necessary and God may or may not implement it. However, if God is all good, He would clearly be obliged to bring into being the best possible world [Sosa, p. 515].
A second argument of his draws its inspiration from Islamic and Aristotelian sciences. He argues that only God is indivisible, and everything other than God is in some way composite or multiple. Kindi describes his concept of God: He has no matter, no form, no quantity, no quality, no relation; nor is He qualified by any of the remaining categories (al-maqulat). He has no genus, no differentia, no species, no proprium, no accident. He is immutable He is, therefore, absolute oneness, nothing but oneness (wahdah). Everything else must be multiple [Sharif, p. 429].
This for Kindi was a crucial distinction upon which he rested some of his main arguments for God's existence. In Kindi's theory only God's oneness is necessary whereas that of all others is contingent upon God. Hence all other beings single or multiple must emanate from the ultimate essential being. In addition this first being must be uncaused, since it is the cause of everything else [Fakhry, p. 78].
The material world cannot exist ad infinitum because of the impossibility of an actual infinite (a concept borrowed from Aristotle). The material world can also not be eo ipso eternal, because of the impossibility of an infinite duration of time, since the existence of time is contingent upon the existence of bodies and motion, which have been shown to be finite. As such the world requires a creator, or rather a generator (mudhith) in Kindi's scheme, who could generate the world ex nihilo [Fakhry, pp. 74-79].
The other arguments he presents are similar versions of the first cause argument, and hence are subject to the same criticisms that apply to any cosmological argument. These criticisms come not only from western scholars but also Islamic ones. Ghazzali is unconvinced by the first-cause arguments of Kindi.
In response to them he writes, According to the hypothesis under consideration, it has been established that all the beings in the world have a cause. Now, let the cause itself have a cause, and the cause of the cause have yet another cause, and so on ad infinitum. It does not behoove you to say that an infinite regress of causes is impossible. [Tahafut, pp. 90-91]
Ghazzali thought that it is at least theoretically possible for there to be an infinite regress, and that there is nothing that necessitates a first-cause simply by pure deductive reason. He thus undermines one of the essential premises of the first-cause argument.
Muhammad Iqbal also rejects the argument stating, "Logically speaking, then, the movement from the finite to the infinite as embodied in the cosmological argument is quite illegitimate; and the argument fails in toto." For Iqbal the concept of the first uncaused cause is absurd; he continues:
It is, however, obvious that a finite effect can give only a finite cause, or at most an infinite series of such causes. To finish the series at a certain point, and to elevate one member of the series to the dignity of an uncaused first cause, is to set at naught the very law of causation on which the whole argument proceeds.
It is for these reasons that modern philosophers almost unanimously reject the cosmological argument as a legitimate proof for the existence of God. Kant for example also rejects any cosmological proof on the grounds that it is nothing more than an ontological proof in disguise. He argued that any necessary object's essence must involve existence, hence reason alone can define such a being, and the argument becomes quite similar to the ontological one in form, devoid of any empirical premises.
Al-Kindi's argument has been taken up by some contemporary western philosophers and dubbed the Kalam Cosmological Argument. Kalam being the Islamic science of dialectical reasoning. Among its chief proponents today is Dr. William Craig [Ramey]. It proposes to show, contrary to what Ghazzali thought, that the universe must have necessarily had a beginning. A contrast is drawn between two concepts, the "potential infinite" and an "actual infinite."
A potential infinite is a concept of an infinite series, to which more things can be added. For example, there maybe and infinite number of integers, however in any one set there will be a finite number of them. An "actual infinite" would be a set which would contain all possible integers.
This would be impossible, since there are an infinite number of integers. Once a set is defined, another integer can always be found to add to it. They can never actually exist. Ramey quotes a famous mathematician, David Hilbert:
the actual infinite is nowhere to be found in reality. It neither exists in nature nor provides a legitimate basis for rational thought -- a remarkable harmony between being and thought.
This forms an essential part of the argument, it demonstrates that an infinite regress could not exist, and that the universe can not possibly be actually infinite, in and of itself. The argument goes on to show that if the universe could not be actually infinite or eternal, given the principle of causality, it must have a first-cause or creator, which is God.
Now, it maybe argued, that if an actual infinite cannot exist, then how can God exist? Since the concept of God, is one of an uncaused and infinite being. Al-Kindi's answer is quite interesting. He states that it is not fair to ask this question of God, since God is not an "actual infinite." God is not a set or collection of things, He is one. God is an absolute unity, and hence on Al-Kindi's scheme God should not be thought of as an 'infinite' [Fakhry, p. 77].
It is not clear, however, if the Kalam argument successfully shows the impossibility of an infinite, a common response (which is also offered by Avicenna) has been to point out that there is no problem imagining an infinite that begins at the present and continues into the future, so it follows that it is entirely conceivable for the same infinity to continue in the past as well [Sharif, p. 503].
Contemporary supporters of this argument have reformulated the first-cause argument to take away the difficulty of explaining why an infinite regress would be impossible. Hick explains, "they interpret the endless series that it excludes, not as a regress of events back in time, but as an endless and therefore eternally inconclusive regress of explanations." Thus a move is made from an infinite regress of events to an infinite regress of explanations.
That is, if events can be explained with reference to other events there must be an ultimate reality of self-explanatory events behind this complex that would make the collective set comprehendible. Hence, no longer is a creator being sought, rather given the creation an ultimate reality is being sought which would explain, or make sense of, the complex and plethora of phenomena in the world. Even here, the non-theistic skeptic will ask what reason do we have to think that the universe is not simply an "unintelligible brute fact"? [Hick, p. 21].
Teleological Arguments
The version of the argument from design is best known in contemporary philosophy as presented by William Paley (1805) in his Natural Theology. He presents us with an analogy of a watch. Suppose that while walking in a deserted remote location one comes across a watch. Upon examining this device one may ask themselves how did this object come into existence.
Surely it could not be by pure chance, it is composed of intricate and complex internal design. We are likely to think that it was a product of an intelligent designer, i.e. there must be a watchmaker.
In the same way Paley argues that the universe is much more complex and manifestly designed. The extraordinary design is evident from planets and galaxies at the cosmic level to human cells and atoms at the quantum level. Therefore this world must have an intelligent creator.
This form of the argument can be seen as an inference to the best explanation. That is given the remarkable phenomena of the universe, the best possible explanation for this, must be the existence of God. Elliot Sober explains this in terms of the Likelihood Principle, which he defines as: "O" strongly favors "H1" over "H2" if and only if "H1" assigns to "O" a probability that is much bigger than the probability that "H2" assigns to "O" [Sober, pp. 31-33].
Here "O" is an observation, and "H" is a hypothesis. The likelihood may be mathematically written as [P (O/H)]: the probability of the observation given the hypothesis. The principle in probability theory form would state that "O" strongly favors "H1" over "H2" if and only if "P(O/H1) >> P(O/H2)." This Sober makes clear is not to be confused with the Probability Principle which states can be written as "[P (H/O)]."
These are two important distinct principles. Sober gives an example of the observation (O) that while sitting in a cabin one hears rumblings in the attic. On the basis of this one forms the hypothesis (H) that there are gremlins in the attic and they are bowling. Now it is clear that the P (O/H) is very high, that is, if there were gremlin's bowling (H) the likelihood of the rumbling noise (O) would be quite high.
But P (H/O) in this case is very low. Since given the rumbling noise (O), the probability of the explanation being bowling gremlins (H) is small. "The gremlin hypothesis has a high likelihood but a low probability given the noises we hear" [Sober, p. 32].
The Likelihood Principle a much better way to understand the inference to the best explanation, since in the case of God a hypothesis is being formed on the basis of observations, in the teleological sense.
Paley, according to Sober, is attempting to apply the Likelihood Principle to the watch example. That is, given that the watch is intricate and well-designed for timekeeping (O), the inference that it was designed by an intelligent creator (H1) is higher than the conclusion that it came into being via random natural processes. Symbolically written it would be stated: P(O/H1) >> P(O/H2).
Paley next argues that if one accepts the above reasoning one is then obliged to accept the reasoning he gives for the universe as a whole, which is as follows:
O - The world is intricate and well-designed for the purpose of supporting life. H1 - The world is the product of an intelligent designer. H2 - The world is the product of random physical processes.
Given the above, again Paley's claim would be that P(O/H1) >> P(O/H2). Both of the above are inferences to the best explanation on the basis of the Likelihood Principle outlined earlier [Sober, p. 33]. Sober later rejects the notion presented by Paley, and argues that the likelihood of an evolutionary hypothesis supersedes the likelihood of a creationist hypothesis.
Al-Kindi also attempts to make reference to the teleological proof (dalil al-'indyah) for the existence of God. He argues that "the orderly and wonderful phenomena of nature could not be purposeless and accidental" [Kindi, p. 61]. This is consistent with the Quranic verse "Not for (idle) sport did We create the heavens and the earth and all that is between!" [Yusuf Ali, Quran 21:16].
The teleological argument analyses the material world and infers from it an Artificer or a creator, a self-conscious being of unlimited intelligence and power, who created this extremely complex world for a purpose and that creator is God. Muhammad Iqbal once again criticizes this argument in the following terms:
At best, it [teleological proof] gives us a skillful external contriver working on a pre-existing dead and intractable material the elements of which are, by their own nature, incapable of orderly structures and combinations. The argument gives us a contriver only and not a creator; and even if we suppose him to be also the creator of his material, it does no credit to his wisdom to create his own difficulties by first creating intractable material, and then overcoming its resistance by the application of methods alien to its original nature. The designer regarded as external to his material must always remain limited by his material and hence a finite designer . [Iqbal, p. 24]
Iqbal is pointing out that any argument from design rests on the extraordinary complexity and almost perfect arrangement of the universe, so as to compel the observer to infer that there must be an intelligent designer. This is consistent with the watchmaker example presented by Paley. The two cases, the watch and the universe, are however, different.
Unlike the case of the watch, where its builder put the complex machine together given pre-existing material, the universe and its material itself created by God also. That is, there is no point in finding it extraordinary that God would be able to organize pre-existing "intractable" material in such an elegant fashion.
The only reason we would have of thinking so, would be if it was a difficult task to design the universe. But then why would God, first create a difficult task for Himself and then go on resolve the difficulty by arranging into a sophisticated pattern? In addition, God would be limited in what He could create by this pre-existing material.
This, to Iqbal, does not seem consistent with the Islamic concept of an omnipotent God. Iqbal writes, perhaps in response to Paley, "There is really no analogy between the work of the human artificer and the phenomena of Nature" [Iqbal, p. 24].
Bertrand Russell joins in this criticism, commenting on the teleological explanation, he professes, but if a man is so obstinately teleological as to continue to ask what purpose is served by the creator, it becomes obvious that his question is impious. It is, moreover, unmeaning, since, to make it significant, we should have to suppose the Creator created by some super-Creator whose purposes He served. [Russell, p. 85]
Both Iqbal and Russell point out that it is inappropriate for a person who believes in God to put forth an argument for His existence on teleological grounds.
The British philosopher David Hume also rejected the teleological argument, for different reasons. For him the argument from the best explanation is an inductive argument, and Hume had argued that inductive knowledge and causation is not possible. Hume rejected all theological works and claimed that they fail certain philosophical tests. He contended that metaphysical knowledge was not possible by either abstract or experimental reasoning. The problem of induction argues that it is impossible to make a justified inference from the observed to the unobserved. This is applicable to all such inferences.
An example of such an inference is the following: we observe that "the sun rises everyday and has risen everyday for over several thousand years" on the basis of this observation we make an inference that: "Hence that the sun will rise tomorrow". Hume claims that we are not at all justified in such an assumption.
He asks what makes such an inference justifiable? Hume recognizes that we spontaneously make such an inference and that perhaps we have no control over it. But he is asking what is our justification for this supposed causal relationship? He asserts where is the causal glue that links the rising of the sun yesterday to the rising of the sun tomorrow?
The only argument that can be made in support of it is that "Nature is uniform," i.e. Nature has been uniform and will remain uniform thus we are justified in making inferences to unobserved events on the basis of what we have been observing. However, it must be noted that this argument in itself is an inductive one and begs the question.
This is similar to the argument for the existence of God from induction, since the argument is being made that we can use empirical/inductive proofs, i.e. we can make inferences based upon what we observe (empirical) to the unobserved (God, Metaphysical). Hume denies that any such inference is at all logically justifiable.
Bertrand Russell in response to this attitude states, it is therefore important to discover whether there is any answer to Hume within the framework of a philosophy that is wholly or mainly empirical. If not, there is no intellectual difference between sanity and insanity . This is a desperate point of view, and it must be hoped that there is some way of escaping from it. [Russell, p. 646]
Most Muslim philosophers have attempted to get around this vexatious problem by simply recognizing the Quranic emphasis on the uniformity of nature, accepting it as such and thus avoiding this problem. The above problem of induction gave rise to modern skepticism and remains a fascinating unsolved puzzle.
Kant's Critique of Empirical Evidence
Kant raises a powerful objection to any theory that claims to grasp knowledge of God. He claims that in terms of knowledge there can be no jump from the physical to the metaphysical. Kant distinguishes between noumanal and phenomenal objects. The noumena are objects that lie beyond all possible experience, and the phenomena are the ones we directly experience.
Hence, for him the metaphysical is the noumenal realm. He argues that there can be no possible relation between two realms that have no connection between them. How can we prove that a certain noumanal object exists from phenomenal premises?, he asks.
Ernst Cassirer, in his book Kant's Life and Thought, comments:
It is especially discordant for Kant on the one hand to consign reason in its determination of actuality completely to the data of experience, and on the other to entrust to it the power of bringing us to unconditional certainty regarding an infinite being lying beyond all possibility of experience. [Cassirer, p. 76]
Although he does not deny that there are metaphysical objects (in fact he argues for their existence from practical reason), he rejects this particular avenue for arriving at what he calls synthetic and a priori objects.
Iqbal responds to Kant's criticism of metaphysical existence from empirical experience as follows: "Kant's verdict can be accepted only if we start with the assumption that all experience other than the normal level of experience is impossible. The only question, therefore, is whether the normal level is the only level of knowledge-yielding experience." He will argue, as we will see later, that there are other levels of experience that can bear knowledge as well.
Ontological Arguments
The modern form of the ontological argument in modern western philosophy was made famous by Anselm and Descartes. The argument rests on the premise that existence is a predicate that a being could have or lack. A summary of Anselm's argument is as follows:
P1) God is a being than which nothing greater can be conceived. P2) A being than which nothing greater can be conceived to exist in our thought. P3) Either a being than which nothing greater can be conceived exists in thought alone and not in reality or a being than which nothing greater can be conceived exists both in thought and in reality. P4)
If the greatest conceivable being existed in thought alone we could think of another being existing in both thought and reality. P5) Existing in thought and reality is greater than existing in thought alone. C) Therefore: A being than which nothing greater can be conceived (God) exists in thought and in reality.
Simply by pure reason, without any reference to the world, Anselm argues for God. A key feature of these kind of arguments is that they try to show not only that God exists, but that he necessarily exists. That is, He cannot, not exist.
The existence of God is an essential feature of its being just like the angles of a triangle always add up to 180 degrees. It would be impossible to think of God without it existing. Descartes writes, from the fact that I cannot think of a mountain without a valley, it does not follow that a mountain and a valley exist anywhere, but simply that a mountain and a valley, whether they exist or not are mutually inseparable. But from the fact that I cannot think of God except as existing, it follows that existence is inseparable from God.
Hence, the very essence of God, to even make the concept of God intelligible it must exist. This argument has been widely criticized.
Kant criticized the argument from two perspectives. First he points out that, although, the concept that all three sides of the triangle add up to 180 is an analytical concept, there is still nothing that shows that it must exist. Similarly the idea that existence analytically belongs to the concept of God is an illegitimate inference.
He writes, To posit a triangle, and yet to reject its three angles, is self-contradictory; but there is no self-contradiction in rejecting the triangle together with its three angles. The same holds true of the concept of an absolutely necessary being. [Kant 3:4]
Secondly, he rejects Descartes argument on the grounds that existence is not a predicate that can be added or taken away from a concept. That is, existence is not like any of the other properties that are associated with 'things.' To say that something exists, is simply to say that the concept is instantiated in the world. He claims this on the basis of his distinction between analytic and synthetic statements.
An analytic statement is one of the kind, "all bachelors are unmarried males," or "the sum of the angles of a triangle is 180." In these statements the predicates, "unmarried males" or "sum of angles is 180" does not add any new information to the concept of "bachelors" or "triangle." Analytic statements are true by virtue of their meaning alone.
A synthetic statement is something that adds more information about the object in question. For example, "all ravens are black," is synthetic. The predicate "are black" tells us more information about the subject "ravens." Kant's claim is that statements of the sort, "X exists" are analytic. It does not add anything additional to the concept. Hence the inference that existing in reality is greater than existence in thought alone is false. The reductio ad absurdum from pure thought to God, of Anselm and Descartes thus fails according to Kant.
The closest form of parallel thought to this can be found in the thought of Avicenna (981 &endash; 1037 CE). He also shared Descartes methodological doubt and proposed a somewhat similar ontological argument for the existence of God [Shiekh, p. 77]. Avicenna also propounded that God is a necessary being, however, his argument unlike Descartes is not a purely rational one.
Avicenna believed that we possess a direct intuitive apprehension of the reality and existence of this necessary being. He believed that it would be impossible to think concretely without the existence of such a being. Averroes, however, insists that there can be no rational proof for God's existence and it can only be grasped via the medium of intuition.
The God that Avicenna argues for is a Necessary Being. A being that necessarily exists, and everything else besides it is contingent and depends upon it for its existence. God has no other essence besides his existence. His essence (mahiyah: quidditas), just is His existence. Since, God is the only being in which the essence and existence are to be found together, the essence of all other beings precedes their existence. Thus He is absolutely simple, and no has no further attributes [Sharif, p. 501].
In his book al-Shifa Avicenna explains that since the Necessary Being has no genus or differentia it is both indefinable and indemonstrable. As such "neither its being or its actions can be an object of discursive thought, since it is without cause, quality, position or time" [Fakhry, pp. 153-154].
All other entities do not exist necessarily or essentially, rather they are merely contingent beings (per accidens). The characteristics of God offered by Avicenna drew major criticisms from the contemporary Muslim orthodoxy, who found his definition incompatible with Islamic doctrine. "not a particle remains hidden from God in the heavens or on the earth" [Quran]. How can God be omniscient if He has no attributes.
He does try to explain, however, how his description would be compatible with God having knowledge of the world. In knowing Himself, God is capable of knowing everything that emanated from Him. Since God does not have sense-perceptual knowledge He cannot know the particulars, but rather only the essences or universal principles.
But according to Avicenna this does not exclude him knowing the specifics of any given event. Knowing all the antecedents and consequences in the causal chain, allows God to place the event temporally and differentiate it from all other events.
Hence, his theory does not preclude God's knowledge of the specifics. Al-Ghazzali was not satisfied with this account and criticized Avicenna stating that the theory being presented would not allow for change in divine knowledge with the introduction of the time factor [Sharif. p. 502].
Another important characteristic of Avicenna's ontology was the fact that he believed that the universe is eternal. This was another belief, which was not acceptable to the Islamic orthodoxy. He thought the creative ability of God was linked to His intellectual nature and thus flowed eternally of rational necessity from Him.
Although the universe exists as an independent body, its existence is still contingent upon God. God and the world are different, but the existence of the world depends upon God. This can be seen as refinement, or rather 'islamization' of the Aristotelian view that God and the universe were two distinct beings which did not interact with each other.
