Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

Metaphysics of The Book of Healing

Time is the measure of motion, in the Aristotelian sense. The world is eternal in the sense that there is no first temporal moment — God's creative act is eternal, not temporal (a position al-Ghazālī attacks as incompatible with Islamic orthodoxy). Within created order, time is linear, deterministic in the sublunary domain through the chain of celestial causation.

Space

Metaphysics of The Book of Healing

Standard Aristotelian-Ptolemaic cosmology: finite spherical cosmos, place as the inner boundary of the containing body. Substantival, three-dimensional, locally interactive.

Matter

Metaphysics of The Book of Healing

Hylomorphic. The active intellect ("giver of forms," wāhib al-ṣuwar) imparts substantial forms to receptive matter. Matter is real, conserved across substantial transformations, the substrate of corporeal substance.

Observer

Metaphysics of The Book of Healing

The Avicennan observer is the rational human soul, embodied in this life but capable of disembodied existence (Avicenna's "flying man" thought experiment argues for the soul's essential separability from the body). Knowledge is total in principle through conjunction with the active intellect. Active in the philosophical-prophetic ascent. The metaphysical agency is personal: the Necessary Existent is the creative cause of all that is, providential in a sense compatible with Islamic theology.

Energy

Metaphysics of The Book of Healing

The Necessary Existent's creative act is the eternal, continuous source of all derived being. Energy in the created order is substantival, conserved across transformations, dissipative within finite processes.

Information

Metaphysics of The Book of Healing

The active intellect contains the substantival forms that are imparted to matter and grasped by the human intellect. Personal information is conserved across death: the rational soul is incorruptible (Shifā Psychology V.4), survives the body, and reaches perfection in conjunction with the active intellect.

Internal Tensions

Where each work's argument pulls against itself.

Metaphysics of The Book of Healing

Al-Ghazālī's Incoherence of the Philosophers (Tahāfut al-Falāsifa, 1095) attacked three Avicennan positions as incompatible with Islamic orthodoxy: the eternity of the world, the denial of God's knowledge of particulars, and the denial of bodily resurrection. The dispute shaped subsequent Islamic philosophical theology decisively. Modern Avicenna scholarship (Marmura, Adamson, Wisnovsky) reads the positions more charitably than al-Ghazālī did, but the tension between philosophical demonstration and revealed orthodoxy is genuinely in the text.
