Overview
Medieval Islamic philosophy spanned several distinct currents; falsafa is not the whole of it. Falsafa was the creative engagement of Muslim thinkers with the Greek philosophical inheritance. It developed alongside, and often in tension with, kalām — the tradition of rational Islamic theology — as well as later Illuminationist and Sufi currents. Avicenna built influential theories of essence and existence, Al-Ghazali challenged the philosophers from within kalām, and Averroes defended philosophy's autonomy — debates that profoundly shaped both the Islamic world and the Latin West.
Key ideas
- Essence and Existence: Avicenna's groundbreaking distinction: in all beings except God, essence (what a thing is) is distinct from existence (that it is). Only in God are essence and existence identical.
- Philosophy and Revelation: Islamic philosophers debated whether philosophical reason and Quranic revelation are compatible. Averroes argued they are two paths to the same truth; Al-Ghazali defended revelation's supremacy.
- Emanation: Al-Farabi and Avicenna described creation as an eternal emanation from God through successive intellects — reconciling Greek cosmology with Islamic theology.

Influenced by
- Peripatetic School
Once the whole of Aristotle's corpus had been translated into Arabic, al-Farabi and Avicenna read it as one system of demonstrative science crowned by the Metaphysics, and Alexander of Aphrodisias's treatises shaped their cosmology and their account of the intellect.
- Neoplatonism
Arabic versions of Plotinus and Proclus, circulating under Aristotle's name as the Theology of Aristotle and the Book on the Pure Good, gave falsafa the hierarchy of One, Intellect, and Soul, and al-Farabi built on it his account of the world arising from the First by necessary, eternal emanation.
Later connections
- Averroism Influenced by this tradition
Siger of Brabant and other Paris arts masters read Aristotle with Ibn Rushd's commentaries, in Latin from about 1230, and took from them his thesis that there is one intellect for all human beings; Siger also took his view that human happiness lies in conjunction with the active intellect.
- Medieval Jewish Philosophy Influenced by this tradition
- Scholasticism Influenced by this tradition
From about 1230 Latin masters read Aristotle through Averroes's commentaries, which became the principal secondary literature of the universities once the Paris arts faculty made all of Aristotle's known works required reading in 1255.
- Sufism Influenced by this tradition
The engagement is that of the later Sufis, Ibn Arabi above all, who cast his teaching in the philosophers' technical vocabulary — wujud for being, and the distinction between what exists necessarily and what exists only possibly — turning those terms to mystical ends.
