Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Ibn Sīnā (Avicenna)
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.
Space
Ibn Sīnā (Avicenna)
Substantival, finite — Avicenna inherits the Aristotelian-Ptolemaic finite cosmos. Three-dimensional, flat in the local sense, locally causal.
Matter
Ibn Sīnā (Avicenna)
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.
Observer
Ibn Sīnā (Avicenna)
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)
Energy
Ibn Sīnā (Avicenna)
Conventional Aristotelian: finite, substantival, conserved.
Information
Ibn Sīnā (Avicenna)
Conserved at both scales. The active intellect holds universal knowledge; the rational soul persists as a separable substance after the body's death.
Internal Tensions
Where each persona's working synthesis strains against itself.
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.
