The Encyclopedia of the Brethren of Purity (Arabic: رسائل أخوان الصفا و خلان الوفا Rasa'il ikhwan as-safa' wa khillan al-wafa; also variously known as the "Epistles of the Brethren of Sincerity", "Epistles of the Brethren of Purity" and "Epistles of the Brethren of Purity and Loyal Friends") was a large encyclopedia in 52 treatises (or "rasa'il") written by the mysterious Brethren of Purity of Basra, Iraq sometime in the second half of the 900s CE (or possibly later, in the 1000s). It had a great influence on later intellectual leading lights of the Muslim world, such as Ibn Arabi and was transmitted as far abroad within the Muslim world as Al-Andalus (Spain). The Encyclopedia contributed to the popularization and legitimization of Platonism in the Arabic world.
The identity and period of the authors of the Encyclopedia have not been conclusively established, though the work has been linked with as varied groups as the Isma'ili, Sufi, Sunni, Mu'tazili, Nusairi, Rosicrucians, etc.
|“||Turn from the sleep of negligence and the slumber of ignorance, for the world is a house of delusion and tribulations. – Encyclopedia of the Brethren of Sincerity||”|
Authorship of the Encyclopedia is usually ascribed to the mysterious "Brethren of Purity" (Arabic: Ikhwan al-Safa), a group of Arab scholars placed in Basra, Iraq sometime around 10th century CE. While it is generally accepted that it was the group who authored at least the 52 rasa'il, the authorship of the "Summary" (al-Risalat al-Jami'a) is uncertain; it has been ascribed to the later Majriti but this has been disproved by Yves Marquet (see the Risalat al-Jami'a section).
Further perplexities abound; the use of pronouns for the authorial "sender" of the rasa'il is not consistent, with the writer occasionally slipping from third person to first-person (for example, in Epistle 44, "The Doctrine of the Sincere Brethren"). This has led some to suggest that the rasa'il were not in fact written co-operatively by a group or consolidated notes from lectures and discussions, but were actually the work of a single person. Of course, if one accepts the longer time spans proposed for the composition of the Encyclopedia, or the simpler possibility that each risala was written by a separate person, sole authorship would be impossible.
The subject matter of the Rasa'il is vast and ranges from mathematics, music, logic, astronomy, the physical and natural sciences, as well as exploring the nature of the soul and investigating associated matters in ethics, revelation, and spirituality.
Its philosophical outlook was Neoplatonic and it tried to integrate Greek philosophy (and especially the dialectical reasoning and logic of Aristotelianism) with various astrological, Hermetic, Gnostic and Islamic schools of thought. Scholars have seen Ismaili and Sufi influences in the religious content, and Mu'tazilite acceptance of reasoning in the work. Others, however, hold the Brethren to be "free-thinkers" who transcended sectarian divisions and were not bound by the doctrines of any specific creed.
Their unabashed eclecticism is fairly unusual in this period of Arabic thought, characterised by fierce theological disputes; they refused to condemn rival schools of thought or religions, instead insisting that they be examined fairly and open-mindedly for what truth they may contain:
|“||...to shun no science, scorn any book, or to cling fanatically to no single creed. For [their] own creed encompasses all the others and comprehends all the sciences generally. This creed is the consideration of all existing things, both sensible and intelligible, from beginning to end, whether hidden or overt, manifest or obscure . . . in so far as they all derive from a single principle, a single cause, a single world, and a single Soul." - (from the Ikhwan al-Safa, or Encyclopedia of the Brethren of Purity; Rasa'il IV, pg 52) ||”|
In total, they cover most of the areas an educated person was expected to understand in that era. The epistles (or "rasa'il") generally increase in abstractness, finally dealing with the Brethren's somewhat pantheistic philosophy, in which each soul is an emanation, a fragment of a universal soul with which it will reunite at death ; in turn, the universal soul will reunite with Allah on Doomsday. The epistles are intended to transmit right knowledge, leading to harmony with the universe and happiness.
Organizationally, it is divided into 52 epistles. The 52 rasa'il are subdivided into four sections, sometimes called books (indeed, some complete editions of the Encyclopedia are in four volumes); in order, they are: 14 on the Mathematical Sciences, 17 on the Natural Sciences, 10 on the Psychological and Rational Sciences, 11 on Theological Sciences.
The division into four sections is no accident; the number four held great importance in Neoplatonic numerology, being the first square number and for being even. Reputedly, Pythagoras held that a man's life was divided into four sections, much like a year was divided into four seasons. The Brethren divided mathematics itself into four sections: arithmetic was Pythagoras and Nicomachus' domain; Ptolemy ruled over astronomy with his Almagest; geometry was associated with Euclid, naturally; and the fourth and last division was that of music. The fours did not cease there- the Brethren observed that four was crucial to a decimal system, as ; numbers themselves were broken down into four orders of magnitude: the ones, tens, hundreds, and thousands; there were four winds from the four directions (north, south, east, west); medicine concerned itself with the four humours, and natural philosophers with the four elements of Empedocles. The number of rasa'il was 51  (; 12 itself can be seen as - the last one on talismans and magic probably was somewhat of an after-thought).
Another possibility, suggested by Netton is that the veneration for four stems instead from the Brethren's great interest in the Corpus Hermeticum of Hermes Trismegistus (identified with the god Hermes, to whom the number four was sacred); that hermetic tradition's magical lore was the main subject of the 51st rasa'il.
Netton mentions that there are suggestions that the 52nd rasa'il is a later addition to the Encyclopedia, because of intertextual evidence: a number of the rasa'ils claim that the total of rasa'ils is 51. However, the 52nd rasa'il itself claims to be number 51 in one area, and number 52 in another, leading to the possibility that the Brethren's attraction for the number 51 (or 17 times 3; there were 17 rasa'ils on natural sciences) is responsible for the confusion. Seyyed Hossein Nasr suggests that the origin of the preference for 17 stemmed from the alchemist Jābir ibn Hayyān's numerological symbolism.
Besides the fifty-odd epistles, there exists what claims to be overarching summary of the work, which is not counted in the 52, called "The Summary" (al-Risalat al-Jami'a) which exists in two versions. The Summary, interestingly enough, has been claimed to have been the work of Majriti (d. circa 1008), although Netton states Majriti could not have composed it, and that Yves Marquet concludes from a philological analysis of the vocabulary and style in his La Philosophie des Ihwan al-Safa (1975) that it had to have been composed at the same time as the main corpus.
Like conventional Arabic Islamic works, the Epistles have no lack of time-worn honorifics and quotations from the Koran, but the Encyclopedia is also famous for some of the didactic fables it sprinkled throughout the text; a particular one, the "Island of Animals" or the "Debate of Animals" (embedded within the 22nd rasa'il, titled "On How The Animals and their Kinds are Formed"), is one of the most popular animal fables in Islam. The fable concerns how 70 men, nearly shipwrecked, discover an island where animals ruled, and began to settle on it. They oppressed and killed the animals, who unused to such harsh treatment, complained to the King (or Shah) of Djinns. The King arranged a series of debates between the humans and various representatives of the animals, such as the nightingale, the bee, and the jackal. The animals nearly defeat the humans, but an Arabian ends the series by pointing out that there was one way in which humans were superior to animals and so worthy of making animals their servants: they were the only ones Allah had offered the chance of eternal life to. The King was convinced by this argument, and granted his judgement to them, but strongly cautioned them that the same Koran that supported them also promised them hellfire should they mistreat their animals.
The first magic squares of order 5 and 6 appear in an encyclopedia from Baghdad circa 983 AD, the Brethren of Purity's Rasa'il Ikhwan al-Safa (Encyclopedia of the Brethren of Purity); simpler magic squares were known to several earlier Arab mathematicians.
Within the Ikhwan was recorded the first nine magic squares, including the first known example of a 6 by 6 magic square.
More metaphysical were the four ranks (or "spiritual principles"), which apparently were an elaboration of Plotinus' triad of Thought, Soul, and the One, known to the Brethren through the Theologia of Aristotle (a version of Plotinus' Enneads in Arabic, modified with changes and paraphrases, and attributed to Aristotle) ; first, the Creator (al-Bārī) emanated down to Universal Intellect (al-'Aql al-Kullī), then to Universal Soul (al-Nafs), and through Prime Matter (al-Hayūlā al-Ūlā), which emanated still further down through (and creating) the mundane hierarchy. The mundane hierarchy consisted of Nature (al-Tabī'a), the Absolute Body (al-Jism al-Mutlaq), the Sphere (al-Falak), the Four Elements (al-Arkān), and the Beings of this world (al-Muwalladāt) in their three varieties of animals, minerals, and vegetables, for a total hierarchy of nine members. Furthermore, each member increased in subdivisions proportional to how far down in the hierarchy it was, for instance, Sphere, being number seven has the seven planets as its members.
|“|| The Absolute Body is also a form in Prime Matter as we explained in the Chapter on Matter. Prime Matter is a spiritual form which emanated from the Universal Soul. The Universal Soul also is a spiritual form which emanated from the Universal Intellect which is the first thing the Creator Created." 
Not all Pythagorean doctrines were followed, however. The Brethren argued strenuously against transmigration of the soul. Since they refused to accept transmigration, then the Platonic idea that all learning is "remembrance" and that man can never attain to complete knowledge whilst shackled in his body must be false; the Brethren's stance was rather that a person could potentially learn everything worth knowing and avoid the snares and delusion of this sinful world, eventually attaining to Paradise, Allah, and salvation, but unless they studied wise men and wise books - like their encyclopedia, whose sole purpose was to entice men to learn its knowledge and possibly be saved - that possibility would never become an actuality. As Netton writes, "The magpie eclecticism with which they surveyed and utilized elements from the philosophies of Pythagoras, Plato, Aristotle and Plotinus, and religions such as Nestorian Christianity, Judaism and Hinduism, was not an early attempt at ecumenism or interfaith dialogue. Their accumulation of knowledge was ordered towards the sublime goal of salvation. To use their own image, they perceived their Brotherhood, to which they invited others, as a "Ship of Salvation" that would float free from the sea of matter; the Ikhwan, with their doctrines of mutual cooperation, asceticism, and righteous living, would reach the gates of Paradise in its care."
Another area in which the Brethren differed was in their conceptions of nature, in which they rejected the emanation of Forms that characterized Platonic philosophy for a quasi-Aristotelian system of substances:
|“||Know, O brother, that the scholars have said that all things are of two types, substances and accidents, and that all substances are of one kind and self-existent, while accidents are of nine kinds, present in the substances, and they are attributes of them. But the Creator may not be described as either accident or substance, for He is their Creator and efficient cause.||”|
|“||The first thing which the Creator produced and called into existence is a simple, spiritual, extremely perfect and excellent substance in which the form of all things is contained. This substance is called the Intellect. From this substance proceeds a second one which in hierarchy is below the first and is called the Universal Soul (al-nafs al-kullīyah). From the Universal Soul proceeds another substance which is below the Soul and which is called Original Matter. The latter is transformed into the Absolute Body, that is, into Secondary Matter which has length, width and depth." ||”|
The 14th edition (EB-2:187a; 14th Ed., 1930) of the Encyclopædia Britannica described the mingling of Neoplatonism and Aristotelianism this way:
|“||The materials of the work come chiefly from Aristotle, but they are conceived of in a Platonizing spirit, which places as the bond of all things a universal soul of the world with its partial or fragmentary souls."||”|
The text in the "Encyclopedia of the Brethren of Purity" demonstrates references to our modern day theory of evolution. The contexts of such passages are interpreted differently by scholars.
In this document some modern day scholars note that “chain of being described by the Ikhwan possess a temporal aspect which has led certain scholars to view that the authors of the Rasai’l believed in the modern theory of evolution” . According to the Rasa’il “But individuals are in perpetual flow; they are neither definite nor preserved. The reason for the conservation of forms, genus and species in matter is fixity of their celestial cause because their efficient cause is the Universal Soul of the spheres instead of the change and continuous flux of individuals which is due to the variability of their cause” . This statement is supporting the concept that species and individuals are not static, and that when they change it is due to a new purpose given. In the Ikhwan doctrine there are similarities between that and the theory of evolution. Both believe that “the time of existence of terrestrial plants precedes that of animals, minerals precede plants, and organism adapt to their environment” , but asserts that everything exists for a purpose.
"[These books] state that God first created matter and invested it with energy for development. Matter, therefore, adopted the form of vapour which assumed the shape of water in due time. The next stage of development was mineral life. Different kinds of stones developed in course of time. Their highest form being mirjan (coral). It is a stone which has in it branches like those of a tree. After mineral life evolves vegetation. The evolution of vegetation culminates with a tree which bears the qualities of an animal. This is the date-palm. It has male and female genders. It does not wither if all its branches are chopped but it dies when the head is cut off. The date-palm is therefore considered the highest among the trees and resembles the lowest among animals. Then is born the lowest of animals. It evolves into an ape. This is not the statement of Darwin. This is what Ibn Maskawayh states and this is precisely what is written in the Epistles of Ikhwan al-Safa. The Muslim thinkers state that ape then evolved into a lower kind of a barbarian man. He then became a superior human being. Man becomes a saint, a prophet. He evolves into a higher stage and becomes an angel. The one higher to angels is indeed none but God. Everything begins from Him and everything returns to Him."
Eloise Hart also describes the evolutionary thought in the work as follows:
"Another section describes the creation of worlds and the evolution of life in details that would have impressed Darwin. It explains how manifestation unfolds through successive layers, or stratified planes down to the mineral kingdom. Where, in this lowest kingdom, the most developed mineral entities live within its highest strata and blend imperceptibly into the next higher or vegetable kingdom. Likewise the vegetable kingdom contacts, at its highest level, the animal kingdom, whose culmination is man. The most evolved men contact higher spheres and, standing between the angelic and animal orders, serve on earth as vicegerents of God."
"...in so far as the sun is to the heavens what the king is to his kingdom and the planets are to it what soldiers, auxiliaries, and subjects generally are to the king, and the spheres are like regions and the constellations like countries and the degrees and minutes like towns, it was enjoined by divine wisdom that it should be located at the center of the universe."
The 48th epistle of the Encyclopedia of the Brethren of Purity features a fictional Arabic narrative. It is an anecdote of a "prince who strays from his palace during his wedding feast and, drunk, spends the night in a cemetery, confusing a corpse with his bride. The story is used as a gnostic parable of the soul's pre-existence and return from its terrestrial sojourn".
Editions & translationsEdit
Complete editions of the encyclopedia have been printed at least thrice:
- Kitāb Ikhwān al-Ṣafā' (edited by Wilayat Husayn, Bombay 1888)
- Rasā'il Ikhwān al-Ṣafā' (edited by Khayr al-din al-Zarkali with introductions by Tāha Ḥusayn and Aḥmad Zakī Pasha, in 4 volumes, Cairo 1928)

The Encyclopedia has been widely translated, appearing not merely in its original Arabic, but in German, English, Persian, Turkish, and Hindustani. Although portions of the Encyclopedia were translated into English as early as 1812, with the Rev. T. Thomason's prose English introduction to Shaikh Ahmad b. Muhammed Shurwan's Arabic edition of the "Debate of Animals" published in Calcutta translated excerpt, a complete translation of the Encyclopedia into English does not exist as of 2006, although Friedrich Dieterici (Professor of Arabic in Berlin) translated the first 40 of the epistles into German; presumably, the remainder have since been translated. The "Island of Animals" have been translated several times in differing completion; the fifth rasa'il, on music, has been translated into English as have the 43rd through the 47th epistles .

What they do lay claim to is system and completeness. The work does profess to contain a systematized, harmonious and co-ordinated view of the universe and life, its origin and destiny, formed out of many discordant, incoherent views; and it does claim to be a 'complete account of all things' - to contain, in epitome, all that was known at the time it was written. It refers to more profound and special treatises for fuller information on the several sciences it touches upon, but it does claim to touch on all sciences, all departments of knowledge, and to set forth their leading results. In effect, it is, by its own showing, a 'hand-encyclopedia of Arabian philosophy in the tenth century'. It is not easy to exaggerate the importance of this encyclopedia.

- ↑ Some have claimed that the Brethren were Ismaili, though this may be unlikely because of their very lukewarm embrace of the Imamate and other aspects of Ismailian theology, in addition to the lack of solid evidence in favor of such a hypothesis.
- This is not to say that there aren't some suggestive links between the Brethren and the Isma'ili. Heinz Halm notes in his "The cosmology of the pre-Fatimid Isma'iliyya" (as printed in Medieval Isma'ili History and Thought, ed. Farhad Daftary, 1996, ISBN 0-521-45140-X) that the Sunni theologian Ibn Taymiyya (d. 1328) asserted that the doctrines of the Brethren were exactly identical to the Ismaili's in one of his fatwas. Halm further notes that Paul Casanova had shown that the infamous Hashshashin had approved of the Encyclopedia and that their missionaries in Yemen even made use of it. Other sects apparently drew upon the Encyclopedia as well: "The theological treatises of the Tayyibi Ismailis of the Yemen contain ample quotations from the Rasa'il Ikhwan al-Safa', and in the 'Uyun al-akhbar by the Yemenite da'i Idris 'Imad al-Din (d. 1468), Ahmad b. 'Abd Allah b. Muhammad b. Isma'il b. Ja'far al-Sadiq, the ninth imam and the second of the leaders of the Isma'ili da'wa residing in Salamiyya, is explicitly named as the author as the Rasa'il." (pg 76) Indeed, the respect of some Ismaili was great indeed, some referring to it as "a Quran after the Quran" (Nasr, 1964, pg. 26). V. A. Ivanov remarks in his The Alleged Founders of Ismailism (Bombay, 1946), that "the work is accepted by the Isma'ili as belonging to their religion, and is still regarded as esoteric..."
- But there are more reasons to reject an identification of the Brethren with Isma'ili, such as the failure of Hamid al-Din al-Kirmani, an extremely important Islamic theologian, to make any mention of them. And other authors agree with this: "...the well-known modern Isma'ili scholar, H. F. al-Hamdani, although emphasizing the importance of the Rasa'il in the Isma'ili mission in the Yemen, disclaims Isma'ili authorship of the work and instead attributes the treatises to the 'Alids." (Amusingly, V. A. Ivanov attributes sponsorship of the work to the 'Alids' enemies, the Fatimids, instead, in his A Guide to Ismaili Literature, London 1933) From pg 26-27 of Nasr (1964).
- From pg 8 of Tibawi: "There is sufficient evidence in the tracts themselves to prove Isma'ili sympathies. Indeed, such sympathies have long been pointed out by Muslim authors, medieval and modern, who tried to turn sympathy into actual relationship. However, the balance of evidence tends to show that such relationship was a later development. There is as yet no proof that the formation of Ikhwan as-Safa and the publication of their Rasa'il was an Isma'ili movement, or even a movement concerted with any of the contemporary agitation of the Shi'a." From page 9: "A glaring example of the Ikhwan's independence is their advocacy of the principle that the office of imam need not be hereditary, for they argue that if the desired good qualities are not found in one single person but scattered among a group, then the group and not the individual should be 'the lord of the time and the imam. More surprising still is the denouncement of the belief in a concealed imam as painful to those who hold it and the discredit of the significance of 'number seven' and those who believe in it as contrary to the Ikhwan's creed."
- Compare this extract from one of the later rasa'il Netton provides on pg 102 of his Muslim Neoplatonists: "Know, O Brother, that if these qualities are united simultaneously in one human being, during one of the cycles of astral conjunctions, then that person is the Delegate (al-Mab'uth) and the Master of the Age (Sahib al-Zaman) and the Imam for the people as long as he lives, If he fulfills his mission and accomplishes his allotted task, advises the community and records the revelation, codifies its interpretation and consolidates the holy law, clarifies its method and implements the traditional procedures and welds the community into one; if he does all that and then dies and passes away, those qualities will remain in the community as its heritage. If those qualities, or most of them, are united in one in his community, then he is the man suited to be his successor in his community after his death. But if it does not happen that those qualities are united in one man, but are scattered among all its members, and they speak with one voice and their hearts are united in love for each other, and they cooperate in supporting the faith, preserving the law and implementing the sunna, and bearing the community along the path of religion, then their dynasty will endure in this world and the outcome will be happy for them in the next."
- ↑ "No one system satisfied these Brethren. They were too well acquainted with other creeds, and too well trained in the logical use of thought, to accept the common orthodox Islam which had contented the desert Arabs. Yet all other creeds and systems equally appeared open to doubt or refutation. In this confusion they found their satisfaction in an eclectic theory. All these conflicting views, they said, must be only different ways of looking at the same thing..." or "These fragments of truth were to be found in every system of faith and every method of philosophy; if men failed to detect them, the fault lay in their own imperfect intelligence - it was only the skill to read between the lines that was wanted to build up a harmonious whole out of the fragments of truth scattered about in sacred books and the writings of wise men and the mystic doctrines of saints."
