(c) They maintain that the universe exists from all eternity and will never end.
None of these propositions has ever been admitted by Moslems.
Besides this, they deny that God has attributes, and maintain that he knows by his essence only and not by means of any attribute accessory to his essence. In this point they approach the doctrine of the Mutazilites, doctrines which we are not obliged to condemn as irreligious. On the contrary, in our work entitled, "Criteria of the Differences Which Divide Islam from Atheism," we have proved the wrongness of those who accuse of irreligion everything which is opposed to their way of looking at things.
(5) Political Science. The professors of this confine themselves to drawing up the rules which regulate temporal matters and the royal power. They have borrowed their theories on this point from the books which God has revealed to his prophets and from the sentences of ancient sages, gathered by tradition.
(6) Moral Philosophy. The professors of this occupy themselves with defining the attributes and qualities of the soul, grouping them according to genus and species, and pointing out the way to moderate and control them. They have borrowed this system from the Sufis. These devout men, who are always engaged in invoking the name of God, in combating concupiscence and following the way of God by renouncing the pleasures of this world, have received, while in a state of ecstasy, revelations regarding the qualities of the soul, its defects and its evil inclinations. These revelations they have published, and the philosophers making use of them have introduced them into their own systems in order to embellish and give currency to their falsehoods. In the times of the philosophers, as at every other period, there existed some of these fervent mystics. God does not deprive this world of them, for they are its sustainers, and they draw down to it the blessings of heaven according to the tradition: "It is by them that you obtain rain; it is by them that you receive your subsistence." Such were "the Companions of the Cave," who lived in ancient times, as related by the Koran (xviii.). Now this mixture of moral and philosophic doctrine with the words of the Prophet and those of the Sufis gives rise to two dangers, one for the upholder of those doctrines, the other for their opponent.
The danger for their opponent is serious. A narrow-minded man, finding in their writings moral philosophy mixed with unsupported theories, believes that he ought to entirely reject them and to condemn those who profess them. Having only heard them from their mouth he does not hesitate in his ignorance to declare them false because those who teach them are in error. It is as if some one was to reject the profession of faith made by Christians, "There is only one God and Jesus is his prophet," simply because it proceeds from Christians and without inquiring whether it is the profession of this creed or the denial of Mohammed's prophetic mission which makes Christians infidels. Now, if they are only infidels because of their rejection of our Prophet, we are not entitled to reject those of their doctrines which do not wear the stamp of infidelity. In a word, truth does not cease to be true because it is found among them. Such, however, is the tendency of weak minds: they judge the truth according to its professors instead of judging its professors by the standard of the truth. But a liberal spirit will take as its guide this maxim of the prince of believers, Ali the son of Abu Talib: "Do not seek for the truth by means of men; find first the truth and then you will recognize those who follow it." This is the procedure followed by a wise man. Once in possession of the truth he examines the basis of various doctrines which come before him, and when he has found them true, he accepts them without troubling himself whether the person who teaches them is sincere or a deceiver. Much rather, remembering how gold is buried in the bowels of the earth, he endeavors to disengage the truth from the mass of errors in which it is engulfed. The skilled coin-assayer plunges without hesitation his hand into the purse of the coiner of false money, and relying on experience, separates good coins from bad. It is the ignorant rustic, and not the experienced assayer, who will ask why we should have anything to do with a false coiner. The unskilled swimmer must be kept away from the seashore, not the expert in diving. The child, not the charmer, must be forbidden to handle serpents.
As a matter of fact, men have such a good opinion of themselves, of their mental superiority and intellectual depth; they believe themselves so skilled in discerning the true from the false, the path of safety from those of error, that they should be forbidden as much as possible the perusal of philosophic writings, for though they sometimes escape the danger just pointed out, they can not avoid that which we are about to indicate.
Some of the maxims found in my works regarding the mysteries of religion have met with objectors of an inferior rank in science, whose intellectual penetration is insufficient to fathom such depths. They assert that these maxims are borrowed from the ancient philosophers, whereas the truth is that they are the fruit of my own meditations, but as the proverb says, "Sandal follows the impress of sandal."[11] Some of them are found in our books of religious law, but the greater part are derived from the writings of the Sufis.
But even if they were borrowed exclusively from the doctrines of the philosophers, is it right to reject an opinion when it is reasonable in itself, supported by solid proofs, and contradicting neither the Koran nor the traditions? If we adopt this method and reject every truth which has chanced to have been proclaimed by an impostor, how many truths we should have to reject! How many verses of the Koran and traditions of the prophets and Sufi discourses and maxims of sages we must close our ears to because the author of the "Treatise of the Brothers of Purity" has inserted them in his writings in order to further his cause, and in order to lead minds gradually astray in the paths of error! The consequence of this procedure would be that impostors would snatch truths out of our hands in order to embellish their own works. The wise man, at least, should not make common cause with the bigot blinded by ignorance.
Honey does not become impure because it may happen to have been placed in the glass which the surgeon uses for cupping purposes. The impurity of blood is due, not to its contact with this glass, but to a peculiarity inherent in its own nature; this peculiarity, not existing in honey, can not be communicated to it by its being placed in the cupping-glass; it is therefore wrong to regard it as impure. Such is, however, the whimsical way of looking at things found in nearly all men. Every word proceeding from an authority which they approve is accepted by them, even were it false; every word proceeding from one whom they suspect is rejected, even were it true. In every case they judge of the truth according to its professors and not of men according to the truth which they profess, a ne plus ultra of error. Such is the peril in which philosophy involves its opponents.
