Abū Ḥāmid al-Ghazālī
Reason within its limits, mystical certainty beyond them — the Ash'arite synthesis of philosophy, law, and Sufism
Al-Ghazālī held the chair of theology at the Nizamiyya madrasa in Baghdad — the most institutionally consequential teaching post in the eleventh-century Sunni world — before a personal-spiritual crisis in 1095 led him to abandon it for eleven years of Sufi practice and travel. The "Incoherence of the Philosophers" (Tahāfut al-Falāsifa, c. 1095) is the systematic critique of Avicennian falsafa on twenty propositions, including the philosophers' claims that the world is eternal, that God does not know particulars, and that bodily resurrection is impossible — al-Ghazālī argued that the falsafa programme as Avicenna had developed it strayed into unbelief on these specific points. The same work develops occasionalism: God is the immediate cause of every event, and what we call natural causation is in fact God's habituated pattern of acting, which he could suspend at any moment. "The Revival of the Religious Sciences" (Iḥyāʾ ʿUlūm al-Dīn, c. 1106) is the encyclopedic synthesis of Sunni jurisprudence, kalām, and Sufi practice; "Deliverance from Error" (al-Munqidh, c. 1108) is the autobiographical account of the crisis and recovery.

Al-Ghazālī is the most institutionally consequential occasionalist in the Sunni Ash'arite tradition. The doctrine that what appears to be natural causation is in fact God's immediate continuous action — developed in the Tahāfut's seventeenth Discussion — became the dominant Sunni position and is the proximate source of Malebranche's later Christian occasionalism.
"The connection between what is habitually believed to be a cause and what is habitually believed to be an effect is not necessary." (Tahāfut, Seventeenth Discussion)
Al-Ghazālī's eleven-year Sufi practice and the Iḥyāʾ's integration of Sufi devotional discipline into mainstream Sunni religious life gave Sufism the institutional respectability it had previously lacked. He is one of the proximate sources of the later Sufi metaphysical tradition that Ibn ʿArabī systematised.
"I learned with certainty that it is, above all, the mystics who walk on the road of God." (Deliverance from Error)
A working but critical engagement: al-Ghazālī mastered Avicennian falsafa (writing The Aims of the Philosophers as a faithful exposition in order to refute it) and accepted much of its logic and natural philosophy even where he rejected its theology.
"He who denies the validity of logic denies the validity of his own argument." (Standard of Knowledge, on the place of logic in religious science)
A structural rather than confessional affinity: al-Ghazālī's emphasis on the immediacy of God's action, the limits of human reason in theology, and the priority of personal religious experience over institutional learning has been compared to Lutheran motifs in comparative theology.
"He whose worship is contemplation and whose knowledge is action — this is the gnostic." (The Niche of Lights)
The "Deliverance from Error" records a sceptical crisis in which al-Ghazālī systematically doubted sense-perception, then reason, before arriving at a divinely-given certainty of fitra (natural disposition toward truth). This is one of the most carefully described episodes of methodical doubt in pre-Cartesian philosophy.
"Knowledge of the truth is acquired by the divine light which God casts into the heart." (Deliverance from Error)
Internal Tensions
The Tahāfut's rejection of Avicennian falsafa was charged by Ibn Rushd in the Tahāfut al-Tahāfut (c. 1180) with destroying the philosophical foundations of natural science and natural theology. Western historiography long blamed al-Ghazālī for the decline of Islamic philosophy after the eleventh century; more recent scholarship (Frank Griffel, Ahmed El Shamsy) has substantially revised this picture, showing that al-Ghazālī integrated philosophical methods into the Sunni mainstream rather than excluding them.
I. Time
"Both" — God's eternity and the finite created order. Deterministic at the level of divine providence; the occasionalist doctrine makes every moment directly willed by God.
Attributes
II. Space
Substantival in the working medieval sense — the proper spatial physics is unaddressed.
Attributes
III. Matter
Non-conserved at the occasionalist level — God recreates the world at each moment, and what we call material continuity is the constancy of his habituated action, not of an enduring substance.
Attributes
IV. Observer
A single embodied person, plural among others. Passive in the technical sense that all action is finally God's. Personal metaphysical agency: the God of the Qur'an, immediately and continuously acting.
Attributes
V. Energy
Emergent within the occasionalist scheme — what we call energy is God's habituated pattern of action.
Attributes
VI. Information
Conserved at both scales by God's knowledge of all things and by the resurrection of the body.
