All creation is necessarily and eternally dependent upon God. It consists of the intelligences, souls, and bodies of the heavenly spheres, each of which is eternal, and the sublunary sphere, which is also eternal, undergoing a perpetual process of generation and corruption, of the succession of form over matter, very much in the manner described by Aristotle. The immortality of individual souls
There is, however, a significant exception to this general rule: the human rational soul. One can affirm the existence of one’s soul from direct consciousness of one’s self (what one means by “I”), and one can imagine this happening even in the absence of external objects and bodily organs. This proves, according to Avicenna, that the soul is indivisible, immaterial, and incorruptible substance, not imprinted in matter, but created with the body, which it uses as an instrument. Unlike other immaterial substances (the intelligences and souls of the spheres), it is not pre-eternal but is generated, or made to exist, at the same time as the individual body, which can receive it, is formed. The composition, shape, and disposition of its body and the soul’s success or failure in managing and controlling it, the formation of moral habits, and the acquisition of knowledge all contribute to its individuality and difference from other souls. Though the body is not resurrected after its corruption, the soul survives and retains all the individual characteristics, perfections or imperfections, that it achieved in its earthly existence and in this sense is rewarded or punished for its past deeds. Avicenna’s claim that he has presented a philosophic proof for the immortality of generated (“created”) individual souls no doubt constitutes the high point of his effort to harmonize philosophy and religious beliefs. Philosophy, religion, and mysticism
Having accounted for the more difficult issues of creation and the immortality of individual souls, Avicenna proceeded to explain the faculty of prophetic knowledge (the “sacred” intellect), revelation (imaginative representation meant to convince the multitude and improve their earthly life), miracles, and the legal and institutional arrangements (acts of worship and the regulation of personal and public life) through which the divine law achieves its end. Avicenna’s explanation of almost every aspect of Islam is pursued on the basis of extensive exegesis of the Qurʾān and the Hadith. The primary function of religion is to assure the happiness of the many. This practical aim of religion (which Avicenna saw in the perspective of Aristotle’s practical science) enabled him to appreciate the political and moral functions of divine revelation and account for its form and content. Revealed religion, however, has a subsidiary function also—that of indicating to the few the need to pursue the kind of life and knowledge appropriate to rare individuals endowed with special gifts. These individuals must be dominated by the love of God to facilitate the achievement of the highest knowledge. In many places Avicenna appears to identify these individuals with the mystics. The identification of the philosopher as a kind of mystic conveyed a new image of the philosopher as a member of the religious community who is distinguished from his coreligionists by his otherworldliness, dedicated to the inner truth of religion, and consumed by the love of God.
Avicenna’s allegorical and mystical writings are usually called “esoteric” in the sense that they contain his personal views cast in an imaginative, symbolic form. The esoteric works must, then, be interpreted. Their interpretation must move away from the explicit doctrines contained in “exoteric” works such as the Shifāʾ and recover “the unmixed and uncorrupted truth” set forth in the “Oriental Philosophy”—the existence of which, as noted above, is spurious. This dilemma has made interpretation both difficult and rewarding for Muslim philosophers and modern scholars alike. The Western philosophers Background and characteristics of the Western Muslim philosophical tradition
Andalusia (in Spain) and western North Africa contributed little of substance to Islamic theology and philosophy until the 12th century. Legal strictures against the study of philosophy were more effective there than in the East. Scientific interest was channelled into medicine, pharmacology, mathematics, astronomy, and logic. More general questions of physics and metaphysics were treated sparingly and in symbols, hints, and allegories. By the 12th century, however, the writings of al-Fārābī, Avicenna, and al-Ghazālī had found their way to the West. A philosophical tradition emerged, based primarily on the study of al-Fārābī. It was critical of Avicenna’s philosophic innovations and not convinced that al-Ghazālī’s critique of Avicenna touched philosophy as such, and it refused to acknowledge the position assigned by both to mysticism. The survival of philosophy in the West required extreme prudence, emphasis on its scientific character, abstention from meddling in political or religious matters, and abandonment of the hope of effecting extensive doctrinal or institutional reform. The teachings of Ibn Bājjah Theoretical science and intuitive knowledge
Ibn Bājjah (died 1138) initiated this tradition with a radical interpretation of al-Fārābī’s political philosophy that emphasized the virtues of the perfect but nonexistent city and the vices prevalent in all existing cities. He concluded that the philosopher must order his own life as a solitary individual, shun the company of nonphilosophers, reject their opinions and ways of life, and concentrate on reaching his own final goal by pursuing the theoretical sciences and achieving intuitive knowledge through contact with the Active Intelligence. The multitude live in a dark cave and see only dim shadows. Their ways of life and their imaginings and beliefs consist of layers of darkness that cannot be known through reason alone. Therefore, the divine law has been revealed to enable human beings to know this dark region. The philosopher’s duty is to seek the light of the sun (the intellect). To do so, he must leave the cave, see all colours as they truly are and see light itself, and finally become transformed into that light. The end, then, is contact with Intelligence, not with something that transcends Intelligence, as taught by Plotinus, Ismāʿīlism, and mysticism. Ibn Bājjah criticized the latter as the way of imagination, motivated by desire, and aiming at pleasure. Philosophy, he claimed, is the only way to the truly blessed state, which can be achieved only by going through theoretical science, even though it is higher than theoretical science. Unconcern of philosophy with reform
Ibn Bājjah’s cryptic style and the unfinished form in which he left most of his writings tend to highlight his departures from al-Fārābī and Avicenna. Unlike al-Fārābī, he is silent about the philosopher’s duty to return to the cave and partake of the life of the city. He appears to argue that the aim of philosophy is attainable independently from the philosopher’s concern with the best city and is to be achieved in solitude or, at most, in comradeship with philosophic souls. Unlike Avicenna, who prepared the way for him by clearly distinguishing between theoretical and practical science, Ibn Bājjah is concerned with practical science only insofar as it is relevant to the life of the philosopher. He is contemptuous of allegories and imaginative representations of philosophic knowledge, silent about theology, and shows no concern with improving the multitude’s opinions and way of life.
