Mullā Ṣadrā and Metaphysics: Modulation of Being (review)

In Mullā Ṣadrā and Metaphysics: Modulation of Being, Sajjad H. Rizvi focuses on tashkīk (modulation), variously translated as the systematic ambiguity, analogical gradation, or just gradation of being from the perspective of Mullā Ṣadrā, comparing it with classical Islamic philosophy and contemporary Western philosophy. He states that he makes two major claims in this study. First, he argues that modulation is a hermeneutic concept that describes the threefold division of being and its gradation. Second, gradation and modulation occur in each mode of being. Each mode of being refers to a branch of Ṣadrā's philosophy: mental being is a discussion of epistemology and psychology; 'being-in-language' is critical to Sadrian semantic theory; being in re focuses on 'traditional metaphysics.' But the philosophy of Ṣadrā is not compartmentalized; being cuts across these fields and unites them. Each mode of being as modulated shares features of intensification. According to Rizvi, Ṣadrā has extended the normal understanding of modulation and of being beyond the simple division of the two realms of mental and concrete existence to bring out the semantics of being. This aspect of Islamic philosophy, according to Rizvi, has often been neglected (p. 3).

This study consists of an Introduction and two parts. In the Introduction, Rizvi states the problem of tashkīk as the central hermeneutic of Ṣadrian ontology. An analysis of this critical concept, according to Rizvi, facilitates our understanding of Ṣadrā's position on a wide variety of important philosophical issues such as predication, the problem of reconciling unity and plurality in being, and God-world relationship. It provides an answer to the age-old problem of the One and the many, and the median way between the ontological monism of Ibn ʿArabi and the metaphysical pluralism of Avicenna. Rizvi says that according to Ṣadrā there are four levels of being: the concept of being, its reality, its uttered manifestation (sound), and its written manifestation.

Part 1 consists of two chapters. In the first chapter Rizvi outlines his methodology and some of his assumptions about the cultural history of the period and the context of Ṣadrā. The significant contention, according to Rizvi, is that a proper understanding of Ṣadrā's philosophy requires an appreciation of philosophy in the Neoplatonic traditions "as a way of life" that is often closely related to spiritual practice and religious commitment. The aim of philosophical inquiry for Ṣadrā, according to Rizvi, is therapy for the rational soul and its perfecting and development in its path of return to its origins in the One.

Four methodological approaches are utilized in this study. (1) Tashkīk is seen as the central hermeneutic of Ṣadrian metaphilosophy, and not ontology; Rizvi argues that tashkīk is a central guiding principle in Ṣadrā's metaphilosophy and permeates all branches of his philosophical system. (2) The aporetic method is used in analyzing Ṣadrā's philosophy. (3) Rizvi maintains that Ṣadrā's philosophy is processual, for it represents a shift from substance to process metaphysics. (4) Ṣadrian hikmat (philosophy, wisdom) is approached as a metaphilosophical inquiry. Metaphysics is a foundational science for Ṣadrā, instrumental in the possibility of acquiring knowledge and in the construction of definitions and meaningful discourse. Hikmat, according to Rizvi, is doubly transcendent, (1) as a higher synthesis of Avicennan, Illuminationist, Sufi, and esoteric Shiʿite systematic thought, and (2) as a prophetic philosophy that claims to be derived from direct 'revelation.'

The second chapter introduces the tashkīk (modulation) of being. Rizvi traces its historical development from the Aristotelian pros hen homonym to Avicenna, Nasir al-Din Tusi, and Ibn ʿArabi, and offers an account of an intensifying scale of being toward a hierarchy of being that is singular but with multiple degrees defined by their intensity, that is, in terms of scales of intensification and deliberation. He makes explicit the Neoplatonic logic of being that this implies and examines how...
