Ibn Sīnā (Avicenna)
The distinction between essence and existence, the Necessary Being, the floating-man argument — Aristotelian metaphysics in Islamic dress
Avicenna's "Kitāb al-Shifāʾ" (Book of Healing, a vast philosophical encyclopaedia covering logic, natural philosophy, mathematics, and metaphysics) and "al-Qānūn fī al-Ṭibb" (Canon of Medicine, the standard medical textbook of the Islamic world and Latin Europe for six centuries) are the two great works. The metaphysics develops Aristotle's system in a Neoplatonist direction: the famous distinction between essence (what a thing is) and existence (that it is), the proof of God as the Necessary Being whose essence is identical to existence, the emanative cosmology of the ten intelligences, the active intellect as the source of human knowing. The floating-man thought experiment — a man created in mid-air, perceptually isolated, who would still be aware of himself — anticipates Descartes' cogito by six centuries.

Avicenna is the central figure of the mature falsafa tradition. His system became the standard framework against which al-Ghazālī, Ibn Rushd, and subsequent Islamic theology defined themselves.
"Existence is an accident which befalls essence." (Metaphysics of the Shifāʾ, I.5 — the foundational doctrine of the Avicennian distinction)
The Aristotelian doctrine of substances as matter-form composites is the metaphysical substrate of Avicenna's natural philosophy and his account of the soul, even where the Neoplatonist framework supplements it.
"The soul is the first perfection of a natural body possessed of organs and capable of life." (De Anima of the Shifāʾ, drawing on Aristotle's definition)
The emanative cosmology — the Necessary Being from which proceeds the first intelligence, from which the second, and so on through the ten — is straight Plotinian, mediated through the Theology of Aristotle (in fact extracts from Plotinus' Enneads attributed to Aristotle in the Arabic transmission).
"From the One only one proceeds." (Metaphysics of the Shifāʾ, IX.4, the principle of emanation)
Internal Tensions
Avicenna's necessitarian cosmology — the cosmos eternally emanates from the Necessary Being and could not be otherwise — drew the central charge of al-Ghazālī's "Incoherence of the Philosophers" (c. 1095): that the doctrine eliminates divine freedom and contradicts the Quranic teaching of creation in time. Ibn Rushd later defended a different version of the falsafa programme in response; the dispute is one of the great philosophical confrontations in Islamic thought.
I. Time
Eternal in extent (the cosmos is eternally emanated from the Necessary Being) but with directional uni-directional change within the sublunary realm. Deterministic at the level of the celestial intelligences; non-deterministic at the level of human will — a tension Avicenna handled through the doctrine of the rational soul's knowledge of universals.
Attributes
II. Space
Substantival, finite — Avicenna inherits the Aristotelian-Ptolemaic finite cosmos. Three-dimensional, flat in the local sense, locally causal.
Attributes
III. Matter
Emergent from the lower intelligences. Conserved through the four elements and their transformations. The rational soul is a separable substance, distinguishable in principle from the body it inhabits.
Attributes
IV. Observer
A single embodied person whose rational soul is in principle separable. Active agency through the cultivation of the rational soul's connection to the active intellect. Personal metaphysical agency: God as the Necessary Being. The floating-man thought experiment establishes self-awareness independently of sensation. (De Anima of the Shifāʾ I.1)
Attributes
V. Energy
Conventional Aristotelian: finite, substantival, conserved.
Attributes
VI. Information
Conserved at both scales. The active intellect holds universal knowledge; the rational soul persists as a separable substance after the body's death.
