The Kindi Circle (Arabic: دائرة الكندي, romanized: Dāʾirat al‑Kindī) was an intellectual group that flourished during the early Abbasid Caliphate.^[1][2][3] It was led by Arab polymath al-Kindi, the first self-identified philosopher in the Arabic tradition and the first peripatetic philosopher of Islam.^[4][5][6][7] He and his circle received official patronage from the Abbasid caliphs al-Ma'mun, al-Mu'tasim, and al-Wathiq.^[8]

The Kindi Circle was based in Baghdad, Iraq.^[9] It operated in the House of Wisdom.^[10] It was similar to the Hunayn Circle, led by Hunayn ibn Ishaq, which gave the Islamic world reliable Greek texts. But the Kindi Circle did more than translate Greek texts or Syriac translations. It created a philosophical language capable of expressing ideas that had never before been discussed systematically in Arabic. It included translators, editors, philosophers, physicians, mathematicians, and scholars.^[11][12]

The Kindi Circle was an informal but highly productive community united by a common purpose: to translate, understand, and ultimately extend the philosophical heritage of Ancient Greece. It was similar to the Hunayn Circle, which gave the Islamic world reliable Greek texts.^[13]

The Kindi Circle demonstrated that philosophy could flourish within an Islamic civilization without abandoning its Greek origins. Al-Kindi famously insisted that truth should be accepted regardless of its source. The Kindi Circle embodied this principle in practice. Greek philosophy, Syriac scholarship, Arabic language, Christian translators, and Muslim philosophers all contributed to a single intellectual movement.^[14]

Members of the circle translated and studied works on theology, metaphysics, medicine, mathematics, astronomy, optics, music, geometry, logic, and ethics.^[15][16][17]

The Kindi Circle believed Aristotelian natural philosophy and the neo-Platonic view of the creation of the world conformed to Islam.^[18]

Aristotle's natural philosophy explains nature as things that have their own motion, their own causes, and their own mixture of matter and form. It also explains the difference between the world on earth and the world in the heavens.^[19] Neoplatonism says that everything comes from the One through an eternal flow called emanation. The One produces Intellect, Intellect produces Soul, and Soul produces the material world. This is not creation in time, but a natural overflow from a perfect source.^[20]

The Kindian tradition sees harmony between Islam and Greek philosophy, especially the Platonism of Plotinus and Proclus.^[21]

Al-Kindi's philosophical treatises argued that the world is not eternal and that God is a simple One.^[22]

In order to legitimate their interest in Greek philosophy, al-Kindi and his successors, namely al-'Amiri, presented the ancient Greeks as having strong linkage to the Arabs. For example, al-Kindi believed the eponymous ancestor of the ancient Greeks (i.e., the Ionians), was a brother of Qahtan, the ancestor of the Arabs.^[23] Further, like many other Aristotelian Muslim philosophers, such as al-Farabi and Ibn Sina, he also defended the view that the Qur'anic figure Dhu al-Qarnayn was Alexander the Great (see: Iskandar Dhu al-Qarnayn).^[24] Similarly, al-'Amiri presented the Qur'anic sage Luqman as the first one who acquired wisdom and depicted Empedocles as a student of Luqman.^[25]

The philosophical teachings of al-Kindi were opposed by traditionalists such as Ahmad ibn Hanbal and the more rationally orientated Mu'tazila.^[26] Although al-Kindi reached conclusions similar to those of the Mu'tazila on many key issues, such as the oneness of God, the justice of God, and the creation of the Qur'an, the modern scholarly consensus is that he was not a Mu'tazilite theologian (mutakallim). His methodology was fundamentally different; he used philosophical demonstration (falsafa), rather than dialectical theology (kalam).^[27] He was an independent philosopher.^[28][29]

The direct influence of the Kindi Circle lasted only a few generations, yet its intellectual legacy proved enduring.^[30] The Kindian tradition, as an intellectual current, continued into the 10th century CE and was represented by first‑ and second-generation students of al-Kindi.^[31]

Members of the Kindi Circle established Arabic as a philosophical language. Before their work, philosophy largely existed in Greek and Syriac. After them, Arabic became the principal language of philosophical inquiry from Baghdad to Córdoba for nearly five centuries.^[32]

Many of the figures who would dominate later Islamic philosophy built directly upon foundations laid by the Kindi Circle. Al-Farabi inherited its logical vocabulary. Ibn Sina, known in the West as Avicenna, inherited many of its metaphysical concepts. Even philosophers who disagreed with al-Kindi continued to employ the technical terminology first stabilized by his collaborators.^[33]

Al-Kindi had an influence on early medieval Jewish thought mainly through Neoplatonic and early Arab-Islamic Aristotelian ideas. His impact came especially through the metaphysical tradition shaped by Plotinus and Proclus. Scholars describe a form of "Jewish Kindism", in which Medieval Jewish thinkers drew on ideas circulating through al-Kindi's Arabic and Christian Arabic followers.^[34]

Al-Kindi's circle wrote the De causis, an Arabic book that mixed ideas from Plotinus and Proclus. The book was translated into Hebrew four times, and it became an important source for many Medieval Jewish thinkers.^[35]

Al-Kindism is a modern intercultural curriculum idea that views al-Kindi as an intercultural educator. It uses interculturalism, interdisciplinary work, philosophy, theology, and intercultural dialogue, and teaches that intercultural learning is essential for true knowledge in the Arabic intellectual tradition.^[36]
