1095 (Baghdad, immediately before his crisis and withdrawal) · Classical Arabic
Philosophical-theological treatise in twenty discussions · Medieval Islamic theology / Ash'arite kalam

The philosophers contradict themselves on twenty crucial points — and on three of them (the eternity of the world, divine knowledge of particulars, bodily resurrection) they contradict the Quran

Dimension-by-Dimension Evidence

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

Time

The Incoherence of the Philosophers

Al-Ghazālī defends the createdness of time against the Avicennan-Aristotelian eternal-world doctrine. The kalām cosmological argument turns on temporal finitude.

Space

The Incoherence of the Philosophers

Standard medieval cosmology. The atomism of Ashʿarite kalām treats space as discrete grids of atomic positions.

Matter

The Incoherence of the Philosophers

Ashʿarite kalām atomism treats matter as discrete occasionally-re-created atoms. The Incoherence's occasionalist position runs in parallel.

Observer

The Incoherence of the Philosophers

The Ghazalian observer is the Muslim believer whose rational engagement with philosophy must be subordinated to revealed truth. Passive in the sense that real causal power belongs to God alone; active in consenting to and seeking God.

Energy

The Incoherence of the Philosophers

God's direct activity is the only real causal power. Energy as "natural force" is denied; what appears as natural energetics is the customary pattern of God's acts.

Information

The Incoherence of the Philosophers

God's knowledge is total, including of particulars (against the Avicennan position that God knows only universals). Personal information is conserved across death; bodily resurrection is real.

Internal Tensions

Where each work's argument pulls against itself.

The Incoherence of the Philosophers

Averroes's Tahāfut al-Tahāfut is a point-by-point rebuttal of the Incoherence; the resulting debate is one of the central exchanges in medieval philosophy. Whether al-Ghazālī's position is itself a rigorous philosophical position or a fideist deconstruction of philosophy has been disputed. Modern scholarship (Marmura, Frank Griffel) generally defends the work's philosophical seriousness.
