After having become acquainted with the general method of the
inductive argument based on the computation of probabilities, and evaluated it through the
foregoing applications, we shall now proceed to apply it to the demonstration of the
existence of the wise Creator. We shall follow the same steps as before.
1. We notice a constant concord between a vast number of individual phenomena and man's
needs as a living being and the continuation of life for him. We find for instance, that
any change or substitution of any of these phenomena could mean the extinction of human
life on this earth, or at least its paralysis. We shall now give a few examples of these
phenomena.
The earth receives from the sun a quantity of heat sufficient for the development of
life and the fulfillment of the needs of living beings for heat, no more and no less. It
has been observed that the distance separating the earth from the sun is-in complete
harmony with the-amount of heat required for the existence of life on this earth. Had this
distance been double its present measure, there would have not been enough heat to support
life on earth. Conversely, if it were half its present measure, the heat would have been
too intense for life to endure. We observe further that the earth's crust and the oceans
together contain in their various chemical compounds a preponderant quantity of oxygen,
such that it constitutes eight-tenths of all of the water in the world. In spite of this,
and in spite of the great tendency of oxygen to combine with other chemical elements,
still a portion of it remains free in order for it to participate in the formation of air.
This portion provides one of the most essential conditions of life because all living
beings, humans as well as animals, require it for breathing. Were all the oxygen on earth
to be combined with other elements, it would not have been possible for life to exist. It
has been further observed that the quantity of pure oxygen available accords perfectly.
with ,man's needs in his everyday; practical life.
The air contains twenty-one percent oxygen had this ratio been greater, the environment
would have been constantly, threatened with outbreaks of fire. Had this ratio, on the
other hand, been smaller, life would have been difficult if not impossible. Nor would fire
have been available in: sufficient quantity to fulfill its proper functions.
We observe another natural phenomenon which repeats itself millions of times throughout
life. It is an activity which ensures the availability of a specific quantity of oxygen
all the time. When humans and animals breathe in air, they inhale oxygen which is received
by the blood and distributed throughout the body. Oxygen then begins the process of
combustion of the food in the body, from which carbon dioxide is produced. Carbon dioxide
then passes into the lungs and is exhaled, thus ensuring a constant flow of this gas.
Carbon dioxide is in turn a necessary condition for plant life. Plants separate oxygen
from it, which they breathe out into the air, purified and ready to be breathed in again.
Through this exchange between animals and plants, it is possible to retain a constant
quantity of oxygen and without it- this gas would have been unavailable and human life
would never have been possible.
This exchange, moreover, is the result of thousands of natural phenomena which have
coincided in order to produce this specific phenomena which is in perfect accord with the
requirements of life. We further observe that nitrogen, because it is a heavy gas, has a
tendency to descend. Thus when it combines with oxygen in the air it becomes light enough
to be useful for life on earth. We observe also that the quantities of both oxygen and
nitrogen which remain free in the air are in perfect proportion for the one to lighten the
other. Were oxygen to increase or nitrogen to diminish, this process could not take place.
We notice that the air in the earth remains at a constant amount, not exceeding one
millionth of the global mass. This quantity is just right to ensure the possibility of
human life. Had it been greater or smaller, life would be difficult or even impossible.
This is because its increase would have meant a greater pressure on human beings which
they would not have been able to support. Like wise, any decrease in it would make it
possible for meteors, which we see every day to burn all living things, and- even to
penetrate the earths itself.
We further notice that the earth's crust, which absorbs carbon dioxide and oxygen, is
so, structured that it cannot absorb them completely. Had it been thicker, it would have
absorbed them, and plants, animals and men would have perished. Similarly, the distance of
the moon from the earth is of a specific measure necessary for making human life on earth
possible. Had this distance been relatively smaller, the tide caused by the moon would
have been so strong as to move mountains from their places.
We observe many instincts in living beings. Even though an instinct is an abstract
notion, incapable of observation by direct sense experience, the conduct which such
instincts express is not abstract. It is, rather, a phenomenon perfectly capable of
scientific observation. Instinctive conduct resulting from thousands of instincts with
which we become acquainted in our daily life and scientific investigation, is in constant
accord with the aim of promoting and protecting life. Such instinctive conduct is often on
a high level of complexity and technical skill. If we were to break down this conduct into
its individual components, we see that every component is perfectly suited for the
promotion and protection of life.
The physiological structure of man exhibits millions of natural, physiological
phenomena. Yet each phenomenon, both in its physiological role and structure, as well as
in its close link with all other phenomena is always suited to the job of promoting life
and protecting it. Let us consider, for instance, the group of phenomena which work
together to produce the faculty of sight and help us to sense things around us in useful
ways. The lens in the eye refracts images onto the, retina which is made up of nine
layers. The last layer contains millions of rods and cones all arranged in such a way as
to make possible the faculty of sight. There is one anomaly, namely, the image which is
reflected onto the retina, which is reversed. This, however, is only a slight anomaly,
because sight itself is not involved at this stage. Instead, the image is corrected by
millions of nerves leading to the brain, where it is transmitted from the eye. Only then
is the process of seeing complete, at which stage it begins to play its important role in
the overall purpose of promoting life.
Even beauty, fragrance and splendour as natural phenomena are found to exist in
environments - suited for their role of promoting life.
Thus flowers which are usually pollinated by insects are especially attractive,
possessing bright, beautiful colours and enticing fragrances in order to attract the
insect and therefore facilitate the process of pollination. Flowers, which are pollinated
by air, on the other hand, do not possess these characteristics. The phenomenon of sexual
pairs or mates in its general similarity between the physical structure of male and female
in man, animals and plants, and in sexual interaction for the perpetuity of life, is yet
another manifestation of the harmony of nature with the function of promoting life.
If you were to reckon up the dimensions of God's favour, you would not be able to
compute them; surely God is ever forgiving, ever merciful (Qur'an, 16:18)
2. We find that, in millions of cases, the continuous harmony between natural phenomena
and the process of insuring and promoting life may be explained by a single hypothesis
which postulates a wise Creator of this universe who willed to provide this earth with the
elements of life and Himself direct their functions. This hypothesis presupposes all these
instances of harmony.
3. In the third step, we pose the following question: If the hypothesis of a wise
creator were not actually demonstrable, what would the possibility of the existence of all
these congruences between natural phenomena and the process of life preservation be
without there being an intended purpose for this order? It is clear that the probability
of this alternative must presuppose a vast number of coincidences. If, as we saw in a
previous example, the possibility is very remote that the letter you received was not from
your brother but from another person resembling him in all respects (since the possibility
of resemblance of one thousand characteristics is very small), how great do you think is
the probability that this earth on which we live was the creation of non-teleological
matter, one which resembles the wise Creator in millions of attributes?
4. In the fourth step we conclude that the hypothesis presented in: the second step
which postulates a Wise creator, is valid.
5. In the fifth step, we connect this prevailing possibility with the small probability
which we postulated in the hypothesis of the third step. Since probability decreases as
the number of coincidences in the contrary increases, it is natural for the degree of this
probability to become so small that it cannot in any way compare with the high probability
of the third step in the demonstration of any scientific law. This is because the number
of coincidences which must be postulated in the third step is greater than that of the
possibilities of the opposite case. Hence, every probability of this kind must in the end
disappear. [12] Thus we reach the incontrovertible
conclusion: that there is a wise creator of this universe as the innumerable signs (ayat)
of His power and wisdom in the universe testify.
We shall show them our signs in the furthest regions and in, themselves so that
it may become manifest to them that it is the truth. Is it not sufficient that your Lord is
witness over all things? (Qur'an, 41:53)
Surely in the creation of the heavens and the earth; and the alternation of night
and day; and the ship which sails over the sea, laden with goods useful to humankind; and
the water which God has sent from heaven to revive with it the earth after its death, and
dispersed in it every kind of beast; and the change of the winds; and the clouds, made to
serve between heaven and earth, are signs for people who understand (Qur'an,
2:164)
Turn your gaze again (to heaven) do you perceive any flaw? Then turn your
gaze twice again; your sight shall return to you dull and discomforted. (Qur'an,
67:3 -4)
[12]. There are two further problems which must be
over-come. First, it may be observed that any probable substitution for the wise Creator,
in accordance with the method of inductive argument, requites that every phenomenon be
fully adjusted to the process of life preservation and be the creation of a blind
necessity in matter. It further requires that matter, in spite of inner contradictions and
Its effects in itself, be the cause of whatever phenomena take place in it. The purpose of
the inductive method is to establish a preference for the hypothesis of a wise creator
over any substitute theory. This is because that hypothesis requires only one a priori
supposition, namely, a wise being. Any substitute theory, on the other hand, pre-supposes
practical necessities in matter equal to the number of the phenomena under investigation.
The probability of such a substitute would be the probability of a large number of events
and coincidences; it would therefore increasingly diminish until it completely disappears.
This would be the case only if the hypothesis of a wise creator is not presupposed in
explaining a large number of occurrences and coincidences. This appears to be the case
because a wise creator, who would be an explanation for all the phenomena in the universe,
must himself possess aspects of knowledge and power equal to their number. Hence, the
number which this hypothesis must pre-suppose should equal the number of blind necessities
which any substitute theory must presuppose. The question, then, must be asked: Which of
the two hypothesis should be preferred?
In answer, it must be said that a preference arises from the fact that these blind
necessities are completely unrelated, in that the presupposition of any one of them in no
way determines the possibility of the existence or non-existence of any other one. This
means in the language of the computation of probabilities that each occurrence must be
independent from any other one, or at least the degree of probability of each must be
independent from that of any other one. In contrast, the knowledge and potencies which are
required by the hypothesis of a wise creator behind the phenomena under investigation, are
not independent because what is required in the way of knowledge and power as cause of
some of the phenomena, must also be required for all. Thus the presupposition of any
number of aspects of knowledge or power is not in-different to the presupposition of any
other number. Rather, the one is inherently required by the other. This further means, in
the language of the computation of probabilities, that the possibility of the entire
cluster of aspects of knowledge and power is conditioned by the fact that the possibility
of some as inferred from the possibility of others is so high that it often reaches the
level of absolute certainty.
If we wish to evaluate the aggregate of knowledge and power (which we must presuppose
the wise Creator to possess) and compare it with its counterpart of blind necessities, as
to their degree of probability, we must follow the method of the multiplication of the
degrees of probability which is based on the principle of computation of probabilities.
The value assigned to each member of this, aggregate must equal the of every other member,
and so on. This computation, as we know, leads to the decrease of probability and as the
computation factors diminish in number, the degree of improbability diminishes in like
proportion. The multiplication principle, whether it be conditioned or independent, can
demonstrate mathematically that in conditional probabilities we should multiply the degree
of one with that of another; though we must presuppose the existence of the first member,
which is often certain or very close to certainty. Thus the multiplication could not lead
to absolute invalidation or to a very small degree of probability. This is in contrast to
independent probabilities, each member of which would be neutral with regard to any other.
In the first instance the computation would lead to great contradictions in value. From
this would also result the necessity of a detailed application of one method in favour of
the other, in order to explain the conditional principle of multiplication as well as the
independent principle. ( For further clarification of the principle of independent and
conditional probability, see al Usus al mantiqiyyah li'l istiqra, pp. 153-154.)
The other problem is that arising from assigning a value to the prior probability
(Ihtimal qabli) of the case which has been demonstrated inductively. In order for this to
be clarified, a comparison must be made between the inductive proof of the Creator, and
its application in our previous example demonstrating that the letter you had received in
the mail was actually from your brother. This example implies that the speed with which a
person arrives at the belief that the letter he received was actually sent by his brother
(even before opening the letter and reading it) is directly influenced by the probability
of the case. This we call `the prior probability of the case.' If, before opening the
letter, he supposes fifty per cent probability that his brother would send a letter to
him, then he would quickly arrive at the belief that the letter was actually from his
brother, in accordance with the five steps of the inductive argument already discussed.
If, on the other hand, the possibility of receiving a letter from his brother is
negligible, because there is a high degree of probability that his brother was dead, he
would not so quickly conclude that the letter was from his brother, unless he receives
further evidence.
What, then is the way to demonstrate the existence of the Creator on the analogy of the
principle of prior probability of the case? In reality, the case of the existence of the
wise Creator, praised be He, does not fall under the law of probability. It is rather, an
a prior truth whose 'certainty man's native intuition (fitrah) and conscience or
pure sentiment (wijdan) assert. If, however, we suppose that it is a case of
probability and wish to demonstrate' it by the inductive method, then we would determine
the value of its prior probability in the following manner.
We begin by considering every phenomenon under investigation independently. Two
possibilities would then present themselves: One is that of a wise creator, the other of a
bend necessity in matter. Since we are faced with two possibilities without any prior
justification for preferring either one over the other, we should divide the numerical
ratio of certainty equally between them, so that each would be assigned fifty per cent.
Since, however, the probabilities in favour of a wise creator are interconnected and
conditioned, in contrast with those of blind necessity, which are independent and
unconnected, the multiplication results constantly in a decrease of the probability in the
hypothesis of blind necessity and a constant in-crease of the probability of the
hypothesis of a wise creator.
I have observed, however, after long study, that the reason why the inductive
scientific argument does not meet with much approval in European thought and is rejected
by thinkers like Bertrand Russel is the inability of those thinkers to overcome the two
problems which we have here indicated and solved. (For an indepth discussion of the
application of the inductive argument for the existence of a creator and the way in which
it is possible to overcome these two problems, see al-Usus . . ., pp. 441-451.)
