History of Philosophy: al-Kindi
Abū Yūsuf Yaʻqūb ibn ʼIsḥāq aṣ-Ṣabbāḥ al-Kindī أبو يوسف يعقوب بن إسحاق الصبّاح الكندي, more widely known as al-Kindi, lived from about 801-873 CE and was an Arab Muslim philosopher, physician, mathematician, and music theorist who is regarded as the first Islamic Peripatetic philosopher, or following in the philosophical footsteps of Aristotle, and is considered the 'father of Arab philosophy'. He was born to an aristocratic family, his father the governor of Basra and al-Kindi received his early education there. He continued his education in Baghdad, where he found patrons of the Abbasid caliphs al-Ma'mun (who reigned from 813-833) and al-Mu'tasim (who reigned 833-842). He was appointed to the recently established House of Wisdom, the center for translating Greek scientific and philosophical works by al-Ma'mun, a position which was enhanced under al-Mu'tasim, when he appointed al-Kindi to tutor his son. Under al-Wathiq (who reigned from 842-847), al-Kindi lost his favored position, possibly due to rivals at the House of Wisdom, or possibly due to al-Wathiq's 'often violent persecution of unorthodox Muslims (as well as of non-Muslims)', with al-Kindi being 'beaten and his library temporarily confiscated' at one point. Caliph al-Mutawakkil (who reigned from 847-861) employed al-Kindi as a calligrapher at one point due to the beauty of his calligraphy. He reportedly died 'a lonely man' during the reign of al-Mu'tamid (who reigned from 870-892).
While philosophy itself was rarely objected to, the conclusions that philosophers reached could be objected to by theologians for extolling intellect, 'believing in the co-eternity of the universe with God, denying the bodily resurrection, and asserting that God only has knowledge of abstract universals, not of particular things'. Al-Kindi was 'fortunate enough to enjoy the patronage of the pro-Mutazillite Caliphs al-Ma'mun and al-Mu-tasim', which means they held to 'an Islamic type of rationalism' that allowed al-Kindi the freedom to explore his work with 'relative ease'. Some hold that al-Kindi's 'real role' was to set the ground for debate between philosophers and theologians, with his work containing 'all the seeds of future controversy that would be fully realized in al-Ghazali's [about 1058-19 December 1111] Incoherence of the Philosophers'.
After his death, al-Kindi's works were lost, partially due to al-Mutawakkil's suppression and partially due to the Mongols invasion and subsequent destruction of libraries from 1219-1258, as well as the popularity of other philosophers, like al-Farabi and Avicenna. He left behind at least 260 books, with 32 about geometry, 22 on medicine and philosophy, 12 on physics, and 9 on logic, with most lost through time, but some surviving due to Latin translations by Gerard of Cremona, an Italian translator who lived from about 1114-1187, and others being rediscovered, including 24 that were found in the mid-20th century in a Turkish library.
