The Hierarchy of Knowledge between Avicenna’s Falsafa and al-Kirmānī’s Ismaili Neoplatonism


In April 2026, Wissam Saadé delivered four lectures at the University of Bologna. The first, at the invitation of Professor Giovanni Giorgini, entitled “The Prophet and the Philosopher: The Hierarchy of Knowledge between Avicenna’s Falsafa and al-Kirmānī’s Ismaili Neoplatonism,” is presented here in a revised and expanded version, published as a series of ten articles.
The series explores the intellectual landscape of Islamic Neoplatonism through a comparative reading of Avicenna and al-Kirmānī. While both thinkers share a broadly Neoplatonic horizon, shaped by a metaphysics of emanation, a hierarchy of being, and a synthesis of Aristotelian and Platonic thought, they develop distinct philosophical projects: Avicenna within the tradition of Peripatetic falsafa, and al-Kirmānī within the framework of Ismaili theology. Despite these different intellectual contexts, their systems remain engaged in a continuous dialogue over the nature of knowledge, the relationship between reason and revelation, and the ascent of the soul. Their respective projects also embody contrasting conceptions of the political, illuminating different ways of understanding the place of philosophy in relation to authority, law, and the organization of the community. This article constitutes the fifth installment of this ten-part series.
V - Between Ineffability and Necessity: The Cairene Crisis and the Ontological Turn
The arrival of Ḥamīd al-Dīn al-Kirmānī in Cairo must be understood against the background of one of the most intense theological and political crises in the history of the Fatimid Ismaili daʿwa: the final years of the reign of al-Ḥākim bi-Amr Allāh (r. 996–1021). This crisis culminated in the “Druze dissidence.” The primary cause was the declaration by certain agitators that the Caliph-Imam al-Ḥākim was not merely the “Proof of God” (Ḥujjat Allāh) or a “Pillar of the Pleroma,” but the absolute manifestation of the Godhead itself. Historically, al-Ḥākim’s own attitude toward these figures remained fluctuating, a mercurial stance that only further fueled the antinomian impulse of the movement. These dissidents argued that, because the “End of Times” and the “Final Truth” had been realized in the person of al-Ḥākim, the external religious law (ẓāhir), including prayer, fasting, and pilgrimage, had become obsolete. In their view, the mediation of the Law was no longer necessary in the face of radical, unmediated presence.
From the perspective of the official Fatimid daʿwa, this development represented a dangerous deviation. Traditional Ismaili doctrine maintained a strict metaphysical distinction: God is absolutely transcendent and beyond all predication, while the Imam is a uniquely chosen human being who serves as the authoritative interpreter (muʾawwil) of divine revelation. Any collapse of this distinction into notions of incarnation (ḥulūl) or divine manifestation threatened the very structure of Ismaili monotheism.
It is within this context of doctrinal rupture that al-Kirmānī was summoned to Cairo by the central institution of the Fatimid daʿwa. As one of the most intellectually sophisticated Ismaili philosophers of his time, he was uniquely equipped to respond to this crisis. Against the emerging tendencies toward the deification of al-Ḥākim, al-Kirmānī reasserts a strictly hierarchical cosmology. In his system, God remains absolutely transcendent; from Him proceeds the First Intellect through divine origination (ibdāʿ), followed by a structured hierarchy of intellects and cosmic principles. Within this architecture, no human figure, including the Imam, can occupy the level of divinity or incarnation. The Imam remains an essential epistemic and hermeneutical authority, but strictly within the created order.
Al-Kirmānī’s thought is inseparable from a triple task and a three-dimensional tension. First, he sought to establish Fatimid Ismailism as an institutionalized Islam rooted in a scholarly jurisprudential tradition, a project centrally shaped by the work of al-Qāḍī al-Nuʿmān. Second, he aimed to build Ismailism simultaneously as a proselytizing movement (daʿwa), both within and beyond the borders of the empire, and as an imperial religion. Third, the objective was to frame Ismailism as a philosophical and, by the standards of the time, scientific religion, deeply rooted in the cosmology and astronomy of the era.
All of this raises a central question: how can an esoteric doctrine govern an exoteric state, and conversely, how can a visible empire be grounded in an invisible metaphysics? For a thinker like al-Kirmānī, the answer lies in the theory of correspondence between the celestial and terrestrial orders: everything in the higher world has its analogue in the lower. The structure of the Imamate thus mirrors the cosmic hierarchy.
The Quietude of the Intellect
In rectifying the previous Neoplatonic model inherited from al-Sijistānī, al-Kirmānī expunged even the slightest imperfections from the highest realm. By doing so, he sought to bring earthly life into alignment with a form of concordia, a harmony based on the “Quietude of the Intellect.” This state is achieved once the intellect realizes that the First Intellect is the first originated and the first existent; that its origination stems from a Source that is eternally and infinitely veiled; that any inquiry into what lies “beyond” it is strictly precluded; that what lies “below” it is both intellect (ʿāqil) and intelligible (maʿqūl); that the Imamate is the earthly image of this system of Intellects; and that the Imamate serves as the link to the light of these Intellects, rather than as a manifestation of the Veiled One, who never manifests.
Al-Kirmānī coupled this with an attempt to preclude any form of intellectual independence in which the intellect might assert its own self-sufficiency rather than humble itself to receive the teachings of the Imam, who alone possesses the key to esoteric interpretation (taʾwīl). He further emphasized a rigorous balance between the esoteric (bāṭin) and the exoteric (ẓāhir), between philosophical gnosis (ʿirfān) and jurisprudence (fiqh), and between the two forms of worship: the intellectual and the practical.
From Cairo to Alamut
The period of al-Ḥākim bi-Amr Allāh (386–411 AH / 996–1021 CE) represents the “critical” or “dramatic” moment in Ismaili history. It exposed the latent fissures between the multiple dimensions of the Ismaili project. When al-Ḥākim bi-Amr Allāh mysteriously disappeared one night in 411 AH, the “bridge” al-Kirmānī was attempting to reinforce collapsed. A segment of the daʿwa, especially in the Levant, refused to believe that al-Ḥākim was dead. They viewed his disappearance as “Occultation” (ghayba). This led to the emergence of the Druze faith, which broke entirely with the Fatimid imperial framework.
This demonstrated that the “imperial” dimension could no longer contain the “revolutionary” calling. The caliphs who followed al-Ḥākim, al-Ẓāhir and then al-Mustanṣir, were forced to adopt a highly conservative line in order to preserve the throne. They marginalized the “dangerous” cosmic and philosophical dimensions that had nearly destroyed the state, focusing instead on traditional imperial governance.
Missionaries in Persia and Khorasan, such as Nāṣir-i Khusraw (1004–c. 1088 CE) somewhat later, found themselves confronting a vast gap. While they preached about a Cosmic Imam who would transform history, they saw a court in Cairo sinking into the petty struggles of viziers and palace guards. This tension eventually led to the Great Schism: the Nizārī-Mustaʿlī conflict.
The final rupture occurred with the rise of Ḥasan-i Ṣabbāḥ and the establishment of the state at Alamut. Recognizing that the Fatimid center in Cairo had traded its revolutionary soul for the trappings of a stagnant empire, the Eastern Ismailis, the Nizārīs, severed ties with the Cairene caliphate. In the rugged mountains of Persia, the “revolutionary calling” was finally decoupled from the “imperial dimension.” Alamut transformed the Ismaili project into a decentralized, militant network of fortresses, replacing the formal jurisprudence of Cairo with the doctrine of taʿlīm, the authoritative instruction of the Imam. This shift represented the ultimate triumph of the “Hādī” spirit, militant, secretive, and philosophically intense, over the compromised political structures that al-Kirmānī had once hoped to save.
From Ineffability to Necessity
The intellectual trajectory of the Ismaili daʿwa presents a striking paradox: the transition from Cairo to Alamut was marked by a shift from radical apophaticism toward an ontological, Avicennian framework.
Early Fatimid thinkers such as al-Sijistānī and al-Kirmānī upheld a strict apophatic theology. They maintained that the Originator (al-Mubdiʿ) was so transcendently “Other” that He stood beyond existence and non-existence. This “double negation” was designed to protect tawḥīd from any human or material association, placing the Divine beyond the reach of language and logic.
In contrast, the Alamut period, catalyzed by the declaration of the Qiyāma, a transformative event proclaimed at Alamut in 1164 CE that prioritized the spiritual essence of the ḥaqīqa over the formal requirements of the sharīʿa, and later refined by Naṣīr al-Dīn al-Ṭūsī (1201–1274 CE), incorporated the language of the wājib al-wujūd, the Necessary Existent. As Avicennian metaphysics became the standard for high philosophy in the twelfth and thirteenth centuries, Alamut’s thinkers adopted these categories to ensure intellectual rigor. While al-Kirmānī’s Neoplatonism was a dense, elitist system, the besieged state of Alamut required a more direct metaphysical grounding. By embracing the “Necessary Existent,” Alamut theology tethered the cosmic order more firmly to the authoritative instruction (taʿlīm) of the Imam, providing a stable ontological foundation for a community in a state of permanent revolution.
When the Mongols under Hülegü Khan destroyed Alamut in 1256, al-Ṭūsī surrendered alongside the last Imam, Rukn al-Dīn Khurshāh. He soon became a chief adviser to Hülegü and helped establish the Maragheh Observatory.
From this point onward, al-Ṭūsī’s public works shifted toward Twelver Shiʿism. He wrote the Tajrīd al-Iʿtiqād (The Catharsis of Faith), which became a foundational text of Twelver theology.
Paradoxically, the systematization of the intelligible world undertaken by al-Kirmānī in his masterwork, Rāḥat al-ʿAql, likely exerted a more profound influence on the Druze Unitarians than on any other group. Although his mission to Cairo was initially intended to refute the founding fathers of this community, his cosmological rigor became the very intellectual foundation upon which they constructed their own doctrinal edifice.
