The following is a list of the rasa'il (epistles) which compose the influential Neoplatonic encyclopedia, the Encyclopedia of the Brethren of Purity composed by the Brethren of Purity in the tenth century CE in Basra, Iraq.
The following tabulation of the rasa'il is principally drawn from a work entitled "Notices of some copies of the Arabic work intitled "Rasàyil Ikhwàm al-cafâ"", written by Aloys Sprenger, originally published by the Journal of the Asiatic Society of Bengal (in Calcutta) in 1848. Doubts have been raised by A. L. Tibawi as to the accuracy of Sprenger's catalogue: "But it is unfortunate that his account is marred by loose translation and too many misreadings of or misprints in the Arabic, and his collection omits the fourteenth tract, merges the eighth with the ninth, and leaves the text of the twelfth and thirteenth confused."

Islamic philosophy is philosophy that emerges from the Islamic tradition. Two terms traditionally used in the Islamic world are sometimes translated as philosophy—falsafa, which refers to philosophy as well as logic, mathematics, and physics; and Kalam, which refers to a rationalist form of Scholastic Islamic theology which includes the schools of Maturidiyah, Ashaira and Mu'tazila.
Early Islamic philosophy or classical Islamic philosophy is a period of intense philosophical development beginning in the 2nd century AH of the Islamic calendar and lasting until the 6th century AH. The period is known as the Islamic Golden Age, and the achievements of this period had a crucial influence in the development of modern philosophy and science. For Renaissance Europe, "Muslim maritime, agricultural, and technological innovations, as well as much East Asian technology via the Muslim world, made their way to western Europe in one of the largest technology transfers in world history." This period starts with al-Kindi in the 9th century and ends with Averroes at the end of 12th century. The death of Averroes effectively marks the end of a particular discipline of Islamic philosophy usually called the Peripatetic Arabic School, and philosophical activity declined significantly in Western Islamic countries, namely in Islamic Spain and North Africa, though it persisted for much longer in the Eastern countries, in particular Persia and India where several schools of philosophy continued to flourish: Avicennism, Illuminationist philosophy, Mystical philosophy, and Transcendent theosophy.
The microcosm–macrocosm analogy refers to a historical view which posited a structural similarity between the human being and the cosmos as a whole. Given this fundamental analogy, truths about the nature of the cosmos as a whole may be inferred from truths about human nature, and vice versa.
Abū Bakr Muḥammad ibn Yaḥyà ibn aṣ-Ṣā’igh at-Tūjībī ibn Bājja, best known by his Latinised name Avempace, was an Andalusi polymath, whose writings include works regarding astronomy, physics, and music, as well as philosophy, medicine, botany, and poetry.
Jacob ben Machir ibn Tibbon, of the Ibn Tibbon family, also known as Prophatius, was a Jewish astronomer; born, probably at Marseilles, about 1236; died at Montpellier about 1304. He was a grandson of Samuel ben Judah ibn Tibbon. His Provençal name was Don Profiat Tibbon; the Latin writers called him Profatius Judæus. Jacob occupies a considerable place in the history of astronomy in the Middle Ages. His works, translated into Latin, were quoted by Copernicus, Reinhold, and Clavius. He was also highly reputed as a physician, and, according to Jean Astruc, Ibn Tibbon was regent of the faculty of medicine of Montpellier.
This article covers the conversations between Islamic philosophy and Jewish philosophy, and mutual influence on each other in response to questions and challenges brought into wide circulation through Aristotelianism, Neo-platonism, and the Kalam, focusing especially on the period from 800–1400 CE.
Early Islamic law placed importance on formulating standards of argument, which gave rise to a "novel approach to logic" in Kalam . However, with the rise of the Mu'tazili philosophers, who highly valued Aristotle's Organon, this approach was displaced by the older ideas from Hellenistic philosophy. The works of al-Farabi, Avicenna, al-Ghazali and other Muslim logicians who often criticized and corrected Aristotelian logic and introduced their own forms of logic, also played a central role in the subsequent development of European logic during the Renaissance.
Ibn Miskawayh, full name Abū ʿAlī Aḥmad ibn Muḥammad ibn Yaʿqūb Miskawayh al-Rāzī was a Persian chancery official of the Buyid era, and philosopher and historian from Parandak, Iran. As a Neoplatonist, his influence on Islamic philosophy is primarily in the area of ethics. He was the author of the first major Islamic work on philosophical ethics entitled the Refinement of Character, focusing on practical ethics, conduct, and the refinement of character. He separated personal ethics from the public realm, and contrasted the liberating nature of reason with the deception and temptation of nature. Miskawayh was a prominent figure in the intellectual and cultural life of his time.
Abu Ya'qub Ishaq ibn Ahmad al-Sijistani or al-Sijzi (السجزي), also known as Bandaneh, was a 10th-century Persian Ismaili missionary active in the northern and eastern Iranian lands. His life is obscure, but he was a prolific writer, who played a crucial role in the infusion of Neoplatonic ideas into Isma'ili theology.
Nous, from Greek: νοῦς, is a concept from classical philosophy, sometimes equated to intellect or intelligence, for the faculty of the human mind necessary for understanding what is true or real.

The Encyclopedia of the Brethren of Purity 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 is an Islamic encyclopedia in 52 treatises (rasā'il) written by the mysterious Brethren of Purity of Basra, Iraq sometime in the second half of the 10th century CE. 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.
In medieval philosophy, the active intellect is the formal (morphe) aspect of the intellect (nous), according to the Aristotelian theory of hylomorphism. The nature of the active intellect was a major theme of late classical and medieval philosophy. Various thinkers sought to reconcile their commitment to Aristotle's account of the body and soul to their own theological commitments. At stake in particular was in what way Aristotle's account of an incorporeal soul might contribute to understanding of deity and creation.
Abu al-Husayn Ahmad ibn Abd Allah ibn Muhammad ibn Isma'il, commonly known as Muhammad al-Taqi, was a descendant of the Islamic prophet Muhammad and the ninth of the Isma'ili Imams, succeeding his father, Ahmad al-Wafi. Like his father, he lived primarily in Salamiyah, and Abd Allah ibn Maymun al-Qaddah, the chief missionary, continued to serve as the hijab for him. Known by the title Ṣāḥib al-Rasāʾil, al-Taqi is said to have prepared with his followers an encyclopedic text called the Encyclopedia of the Brethren of Purity. He died in 840 in Salamiyah and was succeeded by his son al-Husayn.

Before his death in 881, he entrusted the care of his son and successor, Abd Allah al-Mahdi who was then around 8 years old to his full brother, Sa'id al-Khayr, also known as Abu'l-Shalaghlagh.

Abū aṣ-Ṣalt Umayya ibn ʿAbd al-ʿAzīz ibn Abī aṣ-Ṣalt ad-Dānī al-Andalusī, known in Latin as Albuzale, was an Andalusian-Arab polymath who wrote about pharmacology, geometry, Aristotelian physics, and astronomy.
