    Isaac Israeli took many of the definitions in his Book of Definitions, among them those of philosophy, from al-Kindi’s treatise on definitions, and followed his Neoplatonic Aristotelianism, departing from it on the emanation of each stage as the “shadow” of the higher.

Works

  • The first treatise of Arabic metaphysics: philosophy as the search for truth from whatever source, arguments that the world cannot be eternal, and God as the True One beyond all description.

Position

Al-Kindi was the first major philosopher writing in Arabic and was honoured as “the philosopher of the Arabs”. He argued that truth should be welcomed from wherever it comes, even from foreign peoples, and that philosophy and prophetic revelation agree. In his metaphysics God is the “True One”, the cause of all being and unity. Unlike later Aristotelians, he argued that the world cannot be eternal but was created in time. His treatises on the intellect and on dispelling sorrow, which draws on Stoic ideas, brought Greek concepts into Arabic and shaped its philosophical vocabulary; al-Farabi and Avicenna built on other foundations.

Life & context

Born around 801 in Kufa into a prominent Arab family, al-Kindi worked in Baghdad under the Abbasid caliphs al-Ma’mun and al-Mu’tasim, at the height of the translation movement that brought Greek science into Arabic. He supervised translations, tutored a caliph’s son and wrote on mathematics, optics, medicine and music. Under al-Mutawakkil he lost favour; he died around 873.
