Having established that religion has apparent and inner meanings, symbolic for the common people and hidden for the learned, Ibn Rushd endeavours in his book: al-Kashf `an Manahij al-Adillah to find out the way to God, i.e., the methods given in the Qur'an to attain to the belief in the existence of God and to the knowledge of His attributes, according to the apparent meaning, for the first knowledge that every reasonable man is entitled to obtain is of the way which leads to the belief in the existence of the Creator.
Since this book was written in a theological form, Ibn Rushd began to review the methods of the various Islamic sects, which he classified into five principal kinds: the Ash'arites, the Mu'tazilites, the Batinites, Hashawites, and the Sufis.16 It was but natural that he should have reserved for his contem¬poraries, the Aah'arites, the greatest part of his discussion, but strangely enough he never referred to the Batinites mentioned in the above classifica¬tion. The Mu'tazilites were briefly discussed along with the Ash'arites, but not separately through their original writings which had not, as he later stated, reached the Maghrib.
The Hashawites maintain that the way to God is listening through oral transmission (al-sama’)17 and not through reason. They mean that faith in God is received from the Prophet and that reason has nothing to do with it. But this contradicts what is mentioned in the Sacred Book which calls men in general to believe through rational proofs.
The Ash`arites hold that the way to God is through reason, but their method is different from the religious way which the Qur'an has called man to follow. They lay down certain dialectical premises from which they start, such as: the world is temporal; bodies are composed of atoms; atoms are created; the agent of the world is neither temporal nor eternal. Their arguments, however, are far from being understood by the common people, and are inconsistent and unconvincing.18
Another Ash`arite way is that of Abu al-Ma`ali.19 It is based on two premises, that the world is probable (ja'iz), and that what is probable is temporal. But this way abolishes the wisdom of creating the creatures as such. The way of Ibn Sina20 is in some respects similar to that of Abu al-Ma`ali; only he substitutes the probable by the possible.
The Sufis21 follow the mystic way. They say that the knowledge of God is thrown into the soul from high above, after we have got rid of our earthly desires. But, this way is not accessible to all mankind, and it abolishes specu¬lation for which people are exhorted all through the Qur'an.
What, then, is the true way to God which is suitable for all mankind? Two ways are mentioned in the Qur'an, called by Ibn Rushd the proof of providence and the proof of creation. The first is teleological and the second cosmological, both starting from man and other beings, not from the universe as a whole.
The proof of providence depends on two principles: the first is that all beings are suitable for the existence of man; and the second is that this suitability is by necessity due to an agent intending to do so by will, since this suitability cannot be achieved by chance. All beings are created for the service of man: stars shine at night for his guidance, his bodily organs are fit for his life and existence. A whole theory of value can be developed from this view.
The proof called creation takes into consideration the animals, plants, and heavens. It is also based on two principles: that all beings are created, and that everything created is in need of a Creator. The examples given refer to animated beings. When we see that bodies devoid of life are endowed with life, we know by necessity that there is a Creator of life, i.e., God. Heavens, also, are commanded to move and take care of the sublunary world. God says in the Holy Book: “Verily, those on whom ye call beside God could never create a fly if they all united to do so.” 22 He who wants to know God should know the essence and uses of things to attain to the knowledge of true creation.
These two ways are common both to the learned elite and the masses. The difference between their knowledge lies in the degree of details.23 Common people are content with the sensuous knowledge, which is the first step to science. The elite are convinced only by demonstration.
The significance of God's unicity is expressed in the Qur'anic principle “No God but He.”24 Negation of other deities is considered here to be an addi¬tional meaning to the affirmation of God's unicity.25 What would happen if there were more than one God? The world would be subject to corruption: one god would be superior to the others, or the rest of the gods would find some device to dethrone the one in power.26
God is qualified by seven main attributes:27 knowledge, life, power, will, audition, sight, and speech. They are human qualifications considered in their absolute perfection. Three positions can be taken as regards the relation between God's essence and His attributes. The first is the negation of the attributes. This is the position of the Mu'tazilites. The second is to affirm them in a state of complete perfection. The third is to conceive them as trancendent and beyond human knowledge. They are in the sphere of the unknowable.
As a matter of fact, the Qur'an asserts the attributes and yet states that “Nothing is similar to Him,”28 which means that He is unknowable. The common people may believe according to the apparent meaning of the text that He sees, hears, speaks, etc. The people of demonstration should not expound their interpretation before the masses.
The doctrines of both the Mu'tazilites and the Ash'arites are unsound. Ibn Rushd criticizes their solutions in his book al-¬Manahij and at length in the Tahafut. He holds that in the case of the attri¬butes, without affirming or negating them, one must follow the apparent meaning mentioned in the Qur'an. As to philosophical interpretation, this must be kept esoteric.
The acts of God are reduced to five principal ones: creation, sending the prophets, predestination, justice, and resurrection.29 They constitute the relationship between God and the world and man.
Creation is an act of God. He created the world providentially, not by chance. The world is well ordered and is in a state of the most perfect regularity, which proves the existence of a wise Creator. Causality is presupposed. All the Rushdian proofs depend on the belief that nothing comes to be without a cause, and that there is a definite series of causes emanating from a Prime Cause.
He says: “He who, in the artificial things, denies or cannot understand the caused resulting from causes would have no knowledge of the art or the artisan; similarly, he who denies the existence in this world of the depend¬ence of effects on causes would deny the wise Maker.30
The proof for sending prophets is based on two principles mentioned in the Qur'an. The first is that men of this type are those who prescribe the laws through God's revelation, not through human learning. The act of a prophet is to prescribe laws which if followed by men would bring them ever¬lasting happiness. The second principle is that he who is found to be qualified to perform this act of lawgiving is a prophet.
Just as the act of the physician is to cure the body, and he who effects this cure is a physician, so the act of the prophet is to prescribe laws and he who is found to do this act is a prophet. Theologians assume that our belief in the truth of the prophets lies in the belief in their miraculous acts, which are supernatural. But the Qur'an refuses to follow this way which was common to previous religions.
When the Arabs told Muhammad that they would not believe in him unless he made a spring flow from dry earth, he answered through God's revelation: “I am only a human being, a messenger.”31 The only miracle of Islam is its Holy Book, the Qur'an, which comprises the laws necessary for the well-being of man. Thus, there is nothing supernatural,32 since everything goes on according to natural laws resulting from the close association of causes and effects.
Predestination is a very difficult problem about which the opinions of the Muslim thinkers oscillate from absolute fatalism to absolute free-will. Fatalism abolishes man's freedom, and, consequently, his responsibility. The Mu'tazilites are in favour of free-will which is the ground of man's responsibility for his good and bad doings. If this view is assumed, God has nothing to do with man's acts, man being creator of his own acts. And, consequently, there would be other creators besides the Creator.
The Ash`arites maintain a mid¬way position saying that man is predestined and yet he acquires the power to act. This is their famous doctrine concerning the acquisition (al-kasb). But this solution is, in Ibn Rushd's view, self-contradictory. Their doctrine leads to fatalism.
Man is predisposed neither to fatalism nor to free-will. He is determined. Determinism is the production of acts according to their appropriate causes. Causes are external or internal. Our acts are accomplished both through our will and the compatibility of external happenings. Human will is determined by outer stimuli which are subject to definite regularity and harmonic order according to the universal will of God.
Not only are our acts determined by causes from without, they are also related to causes from within ourselves. The determined regularity in external and internal causes is what we call predestina¬tion.33 God's knowledge of these causes and of what results from them is the reason for their being.
God is just and never does injustice to man, as declared in the Qur'an. The nature of man is not absolutely good, although good is dominant. The majority of mankind are good. God has created good essentially, and bad accidentally for the good. Good and bad are similar to fire which has many uses for the well-being of things, yet in some cases it may be harmful. This Rushdian theory supports the optimism that prevails in the world.
All religions are in accord as to the reality of resurrection. They differ only as to whether it is spiritual or bodily. Spiritual resurrection is the survival of the soul after its separation from the body. Belief in bodily resurrection is more suitable for the minds of the masses who are short of understanding the spiritual immortality of the soul.
