The organically formed universe, created and made to cohere by God, consists of a series of entities of different degrees. Next to the Deity are the pure spirits, which are simple, and not composed of matter and form, and consequently partake most of the divine nature. Their necessary existence is proved philosophically, because many phenomena in the universe best admit of explanation through them. These pure spirits, these "forms free of matter," Judaism and Holy Writ call "angels." Among them must be assumed a spirit or angel who is the originator of thoughts or ideas, the active world-spirit or creative reason (Sechel ha-Poel).

In the degree next to the pure spirits are entities which must certainly be considered as composed of matter and form, whose matter, however, is not heavy and coarse, but of an ethereal nature. These ethereal entities are the heavens and the brilliant world of stars, which possess an ever uniform motion, and are therefore not subject to the change of genesis and dissolution, but revolve in the firmament in constant brightness and with unbroken regularity. These form and influence the lower circle of entities. The stars are divided into four spheres—into the sphere of the fixed stars, of the moving stars (planets), of the sun and the moon. These spheres must be considered as endowed with life and intellectual power. Below the sphere of the moon there exists a grade of entities which are generated from coarser matter, but are susceptible of form, shape, and motion. This is the world of the four elements, which are in their turn fashioned into four spheres, one above the other. Within these spheres are formed, through manifold evolutions, influenced by the world of stars, lifeless minerals, plants, self-moving animals, and men capable of intelligence.

But how is the influence of God upon this multiform universe to be understood? The changes cannot proceed immediately through Him. The animated orbs of stars, which are the cause of all transformations on earth, are not set in motion by God, but are impelled towards Him in longing and love, in order to partake of His perfection, His light, and His goodness. Through this ardent striving of the heavenly bodies to God comes their regular revolution, and in this manner they cause all changes in the world below the moon, in the circle of genesis and dissolution, through the reception and loss of peculiar forms and shapes. This theory of God, of the universe, and the various motions of the different beings, Maimuni found indicated in Holy Writ and in many utterances of the Agada, but only in obscure allusions, as these writings, being designed for every one, not solely for the philosopher, could not and durst not, at the risk of occasioning gross misunderstanding, unveil the complete image of truth.

More important than the analysis of this conception of the world is Maimuni's presentation of his ideas on matters more nearly concerning mankind. Since God, the creator of the world, is perfect and all-good, the world cannot have been made otherwise than good, and in accordance with a purpose. "God saw that all was good," "From on high there comes no evil." The evils which exist in the world are not to be looked upon as the work of God, but merely as the absence of the good and the perfect, since gross matter is incapable of partaking of the good and the divine. God did not create sin, but sin arises from the nature of the coarse matter, which is defective in its constitution, and which can only receive and retain defectively that which is good. But this evil must be overcome. God has implanted in the soul of man, who is superior to all entities composed of gross matter, the capacity and instinct for knowledge. If the soul follows this instinct, it is assisted by the active reason which has been specially created for the purpose of opening up to the soul the source of the divine spirit, in order that it may understand the structure of the world and God's influence upon it, and that it may be enabled to lead a worthy life. Man can thereby raise himself to the higher degree of the angels, and can conquer the frailties which arise out of his material body. Through this elevation to the higher abode of thought and to moral purity, and through mastery of his animal nature, man by his own will acquires a soul; he makes himself a super-earthly being, he wins for himself the immortality of the soul, and becomes united with the all-governing world-soul. The possibility of gaining this highest degree is vouchsafed to man with his freedom of will.

And man can acquire and in a manner win God's special providence in the same way as he can acquire and win immortality through the action of his soul. For God's care extends only to what remains and endures. Even in the lower world of the four elements, this is felt in the preservation of the species, which by reason of their form and purpose are of a spiritual nature. If man raises himself to the degree of a spirit, if he becomes master over matter, the providential eye of God will not pass him over. And as man can gain for himself, through moral and intellectual discipline, an immortal soul, so he incurs the highest penalty if his spiritual light is quenched through a sinful life, and is crushed by his material nature.

Man has the power of acquiring still more; he can, through an ideal life, come to possess the prophetic faculty, if he opens his mind by constant communion with God to the influences of the active reason. But it requires on the part of man cultivation and concentration of the imagination, and on the part of God the emanation of His spirit. Since a lively, continually active imagination is the chief qualification for prophecy, it can develop only in a state similar to a dream, when the disturbing activity of the senses is relaxed, and the mind may freely resign itself to the influences from above. The prophesying of the prophets always occurred in a kind of dream. The Scriptural accounts of the actions and experiences of the prophets during their ecstatic condition, are not to be understood as being accounts of actual occurrences, but only of processes of the soul, as visions of the imagination. There are also different degrees of prophecy, according to the greater or less capacity requisite for them. Thus many miraculous tales in the Bible cease to appear supernatural and surprising, just as the hyperbolical style of the prophets is explicable on this theory. All this arises from the rule of the imagination and dream visions. Miracles are certainly not impossible. The same Creator who has established the laws of nature can also suspend them, but He does so only temporarily, that the old order may soon return, as when the waters of the Nile were changed into blood only for a short time, and the sea divided itself for the Israelites but for a few hours. The number of miracles in the Bible is, however, limited. Wonders are not, generally speaking, the means of verifying and confirming the declarations of the prophets; they must be proved by the prophecies themselves, and the fulfilment of what they predict. Miracles do not prove them true.

The most perfect of all prophets was that man of God with shining countenance, who brought to the world a religion which has exercised the profoundest sway over men's minds. The prophecy of Moses differed from that of later prophets in four essential points. He received the revelation without the mediation of another spiritual being, that is, without the influence of the active reason or of an angel, but communed with the Deity "face to face and mouth to mouth." Secondly, Moses communed with God, not in a dream, when all activity of the senses ceases, but the higher teaching was granted to him whilst he was in an ordinary frame of mind. Moreover, his being was not disturbed or dissolved by it, as in the case of other prophets when the spirit of God came upon them, but he could maintain himself under it. Finally, Moses was continually in the prophetic mood, whereas this power came upon other men of God only after longer or shorter intervals, and then only after careful preparation. Moses possessed this prophetic perfection only because, through the elevation of his mind, he had liberated himself from the tyranny of his senses, from desire, and even from his imagination, and had won for himself the degree of an angel, or of a pure spirit. All coverings which blindfold the eye of the human mind, and disturb its view, he tore off, and penetrated to the fountain-head of truth. He attained to a degree such as no other mortal has reached, and therefore he was able also to recognize the Deity and His will with the undisturbed gaze of a pure spirit. The truth of the highest Being irradiated him without intermediation, and in transparent clearness, without word or speech. That which he perceived at such a height he brought to his people as a religion, as a revelation, and this truth, radiating immediately from the divinity, is the Torah.

This revealed religion, originating from God, is unique, just as the mediator, through whom the truth was conveyed to man, is the only one of his kind. Being a divine doctrine it is perfect, and consequently there can be none which can abrogate its authority, and supersede it, just as there was none previous to it.

The divinity of the Torah is proved by its contents as by its origin. It contains not only laws and precepts, but also dogmas upon questions most important for man, and this two-fold character is likewise a mark to distinguish it at once from other codes and from other religions. Besides, the laws of the Torah all aim at a higher purpose, so that there is nothing in it superfluous, nothing unnecessary, nothing gratuitous. The design of the revelation brought down by Moses can be thus summarized: it was to promote the spiritual and physical welfare of those who received it, the one by inculcating correct ideas of God and His government of the world, the other by enjoining principles of virtue and morality. Maimuni made an attempt to show that the six hundred and thirteen laws of the Torah, or of Judaism, tend to establish a true theory as to the Deity and His relation to the world, to oppose false and pernicious opinions, to uproot false ideas, to remove wrong and violence, to accustom men to virtue, and finally to eliminate immorality and vice. Maimuni arranged all the obligations of Judaism under fourteen groups according to his scheme.

Maimuni's ideal labor, to raise Judaism to the height of a philosophical system, was of the most wide-spread effect. For the thinkers of his time, Maimuni's religious philosophy was, indeed, a "Guide of the Perplexed." For to these men, who were dominated by the same principles, whose thinking, on the one hand, was Aristotelian, and whose feeling, on the other hand, was Jewish, but who, nevertheless, were conscious of a deep gulf between their thinking and their feeling, nothing could have been more welcome than the discovery of a bridge which led from the one to the other. Many things which had appeared to them offensive, or at least trivial, in the Bible, received through Maimuni's ingenious manner of interpretation a higher importance, a deeper sense, and became clear to their understanding. To posterity his philosophical work was both stimulating and suggestive. Judaism, viewed in the light of Maimuni's philosophy, no longer appeared to Jewish students as something strange, belonging to the past, an extinct and mere mechanical system, but as something which belonged to themselves, a part of their consciousness, existing in the present, living in their thoughts and animating them. Jewish thinkers of all times after Maimuni have consequently had recourse to Maimuni's "Guide," have derived fruitful ideas from this source, and have even learnt from him to advance beyond his standpoint, and to combat him. And since in the end thinkers will always remain the guides and leaders of men, and the designers of their future, it can be said with justice, that Judaism is indebted to Maimuni for its rejuvenescence. So exclusively did he hold sway over men of intellect, that for a long time his work completely supplanted the systems of his predecessors from Saadiah to Ibn-Daud.
