The Philosophical Trajectory of Atomism: From Ancient Materialism to Mulla Sadra's Metaphysics of Motion
Summary
The history of atomism reveals a profound evolution of thought, transforming from a metaphysical speculation on the nature of being into a systematic refutation of its own foundational principles. Originating in ancient Greece as a materialist philosophy, it posited a universe of eternal, indivisible particles (atomoi) moving through an infinite void (kenon) governed by mechanical necessity. This framework was later adapted and radically transformed by Islamic Kalam theologians, who repurposed its physics to demonstrate a universe entirely dependent on God's continuous, moment-by-moment creation (Occasionalism).
The culmination of this intellectual trajectory is found in the work of the 17th-century Persian philosopher Mulla Sadra. In his system of Transcendent Wisdom (Al-Hikmah al-Muta'aliyah), Sadra systematically deconstructs the static ontology underpinning all prior forms of atomism. He replaces the concept of reality as discrete, unchanging particles with a metaphysics of pure dynamism, built on three core pillars: the Primacy of Existence (Asalat al-Wujud), the Gradation of Existence (Tashkik al-Wujud), and, most critically, Substantial Motion (Haraka Jawhariyya). This last doctrine posits that the very substance of the universe is not a static "thing" but a constant, fluid process of becoming and intensification.
Sadra’s magnum opus, The Four Journeys of the Intellect, presents this philosophy as a comprehensive map for the soul's evolution. It details an intellectual and spiritual voyage that begins by piercing the illusion of a static, atomic world to grasp the flowing reality of Substantial Motion. The journey progresses to an understanding of the Divine Essence, and culminates in a return to the world to guide society with perfected wisdom. Ultimately, Sadra’s work represents the final synthesis in this lineage, dissolving the atom into a continuous stream of existence and transforming a theory of static matter into a profound vision of cosmic and spiritual evolution.

I. The Foundations of Ancient Atomism
The atomic theory first emerged not as a scientific hypothesis but as a grand metaphysical system attempting to reconcile the permanence of being with the reality of change. Its origins are traced through legendary accounts and philosophical schools that laid the groundwork for its classical formulation.
A. Legendary and Philosophical Origins
- Phoenician Tradition: Ancient testimony from figures like Posidonius and Strabo attributes the origins of atomism to a Phoenician thinker named Mochus of Sidon, who was said to have been active before the Trojan War. However, surviving Phoenician cosmogonical texts, such as that of Sanchuniathon, describe a "wet materialism" based on the evolution of a primeval slime (Mot) and wind (Pneuma), which is biological and fluid-dynamic rather than mechanically atomic. The Mochus tradition, therefore, likely represents a separate lineage or a later Hellenistic attempt to credit Greek philosophy with ancient "Oriental wisdom."
- Pythagorean Monadology: Pythagoras of Samos conceived of the Monad as the primordial, indivisible unity—a metaphysical "seed" of number and being. The term atomos ("that which cannot be divided") originally symbolized this concept of potent, sovereign unity. This differs significantly from the later materialist atom, as the Monad is an immaterial, metaphysical point, whereas the atom of Democritus is a physical, extended particle. Later esoteric interpretations often conflated these two distinct concepts.
B. The Democritean Model: Being, Non-Being, and Necessity
Leucippus and his student Democritus formulated the classical atomic theory, a strictly materialist system designed to explain the cosmos without divine intervention.
- The Binary of Existence: The universe was described as consisting of two co-eternal and infinite principles:
- Ens (Being): Represented by atoms—solid, immutable, and indivisible particles, infinite in number and varying in shape and magnitude.
- Non-Ens (Non-Being): Represented by the vacuum or void (kenon)—an infinite, empty space required for atomic motion. Leucippus asserted that this "non-being" exists just as much as "being."
- Motion and Necessity: The Greeks believed that atoms, though inert, were set into ceaseless motion by an agitating agent termed Necessity (Anankē). This was not a blind force but an immutable, inevitable law governing the collision, interlocking, and rebounding of atoms, leading to the formation of ordered worlds. Plato later characterized this principle as the "spindle of necessity."
- Perception and Qualities: Democritus argued that phenomenal qualities are subjective illusions. His famous dictum states: "By convention sweet and by convention bitter, by convention hot, by convention cold, by convention color; but in reality atoms and void." Secondary qualities like color and taste are merely sensory reactions to the shapes and arrangements of atoms.
C. The Atomic Soul and the Nature of Life
The atomists extended their materialist framework to explain life, consciousness, and even the divine.
- The Soul as Atomic Compound: The soul, mind, and emotions were considered aggregates of finer, subtler, and often spherical atoms. These soul-atoms could permeate the coarser atoms of the body, much as water permeates sand, allowing for a compound existence. Death was merely the dissolution of this compound, with the soul-atoms scattering.
- The Gods as Atomic Beings: Even the gods were envisioned as beings composed of highly refined atomic structures, occupying realms beyond ordinary perception and subject to the same universal laws of Necessity.
- Life and "Atomic Fission": Life was seen as a process of accumulating atoms, while death was the cessation of this replenishment. The ancients speculated on the dissolution of the atomic unit, viewing a voluntary, gradual release of potential (akin to spiritual enlightenment) as a return to pure life. In contrast, they feared a violent, instantaneous release of an atom's total potential, believing it would violate the boundary between "thing" and "nothing," resulting in total annihilation.
II. The Transformation of Atomism in Islamic Kalam Theology
When Greek philosophy entered the Islamic world, atomism was adopted by speculative theologians (Mutakallimūn) not to support materialism, but to defend the core tenets of Islamic monotheism against the Aristotelian doctrine of the world's eternity. This required a radical re-engineering of the atomic theory.
A. From Materialism to Occasionalism
The core goal of Kalam atomism was to prove that the universe is created (huduth) and therefore requires a Creator. The theologians achieved this by atomizing not only space but also time, leading to the doctrine of Occasionalism.
- The Singular Substance (al-Jawhar al-fard): The world is composed of indivisible, point-like units. Unlike the eternal Greek atoms, these are created by God.
- Accidents (‘Arāḍ): Properties like color, motion, and life are not inherent to atoms. They are distinct, real qualities created by God that "inhere" in the atom.
- The Denial of Enduring Accidents: The central principle of Occasionalism is that an accident cannot endure for two consecutive moments (la yabqa zamanayn). If an object remains red, it is because God creates the accident of "redness" in its atoms in every single instant.
B. The Doctrine of Continuous Re-creation
This framework leads to a universe radically dependent on the divine will, known as The Renewal of Likenesses (Tajaddud al-amthal).
- Cinematographic Reality: The universe has no continuity. It is a series of static frames, destroyed and re-created by God in each moment. The illusion of motion and causality arises from the rapidity of this divine act.
- Denial of Natural Causality: A fire does not burn cotton by its own nature. Rather, God creates the accident of "burning" in the cotton on the "occasion" of its contact with fire. There are no secondary causes or natural laws, only the direct, unmediated will of God.
C. A Contrarian View: Al-Naẓẓām and the "Leap" (Ṭafra)
The Mu'tazilite theologian Ibrahim al-Naẓẓām rejected the standard Kalam model of discrete atoms. He argued that matter was infinitely divisible, which exposed him to Zeno's Paradox of motion. To solve this, he proposed the theory of the Leap (Ṭafra), arguing that a moving body does not traverse every point in a continuous line but "leaps" from a starting point to an end point, skipping all intermediate points. This controversial theory, which suggested objects could teleport, was an early attempt to reconcile a continuous view of space with the physics of motion.
III. The Sadrian Synthesis: A Refutation of Static Ontology
Mulla Sadra (Sadr al-Din al-Shirazi) represents the climax of this philosophical lineage. He developed a comprehensive system that did not merely critique atomism but replaced its entire static foundation with a dynamic metaphysics of motion and process.
A. Foundational Pillars of Sadrian Thought
Sadra's "Transcendent Wisdom" is built upon three revolutionary principles that directly counter the premises of both Greek and Kalam atomism.
Pillar | Transliteration | Core Concept |
Primacy of Existence | Asalat al-Wujud | Existence (wujud) is the sole fundamental reality. Essence or "whatness" (mahiyyah) is merely a mental construct used to delimit the singular reality of existence. |
Gradation of Existence | Tashkik al-Wujud | Existence is not a binary state (on/off) but a single, continuous reality that differs in degrees of intensity and weakness, much like light ranging from dim to brilliant. |
Substantial Motion | Haraka Jawhariyya | The very substance (jawhar) of reality is in a constant state of flux, evolution, and becoming. Change is not something that happens to things; it is what things are. |
B. Sadra's Refutation of the Atom
Sadra systematically dismantles the concept of the "indivisible part" (al-juz' alladhī lā yatajazzā) by radicalizing Zeno’s paradoxes, arguing they prove that a reality made of discrete, static atoms is logically impossible.
- Proof of Contact (Burhan al-Tamass): If three atoms (A-B-C) are in a line, does the side of B touching A differ from the side touching C? If yes, atom B is divisible. If no, then A and C are touching the same point, and the universe collapses into a single, non-extended point. Since the universe has extension, the atomic premise is absurd.
- Proof of Alignment (Burhan al-Samt): If two lines of atoms move past each other, they must at some point be halfway aligned. In a discrete (atomic) space and time, there is no "halfway." One atom must "teleport" or "leap" (al-Tafra) past the other, which Sadra rejects as physically impossible.
- The "Diagonal" Argument: In a square made of atoms (e.g., 10x10), the diagonal must also be composed of a whole number of atoms. However, geometry dictates the diagonal is an irrational number (~14.14). Therefore, atomism makes basic geometry impossible.
C. The Nature of Time and the "Flowing Now"
Sadra resolves Zeno's Arrow paradox by redefining time itself. While atomists saw time as a series of discrete "nows" or instants, Sadra proposed the concept of the Flowing Now (al-ān al-sayyāl). He argues that time is not a container for change but is the very measure of the fluid transformation of substance. Static "instants" do not exist in reality; they are mental abstractions we impose upon the continuous flow of becoming.
IV. The Four Journeys: The Culmination of Sadra's System
Sadra’s Four Journeys of the Intellect is the ultimate expression of his philosophy, outlining a comprehensive path of spiritual and intellectual evolution that is made possible by the reality of Substantial Motion.
A. Journey One: From Creation to the Truth
This is the journey from the material world to the Divine Reality (Haqq). The traveler engages in ontological investigation, stripping away the illusion of independent essences to realize that all things are manifestations of a single, graded Existence. Through the lens of Substantial Motion, the traveler understands the evolution of being—from matter to vegetation, animal, and finally the human soul, which is "bodily in its origination but spiritual in its survival." The journey culminates in the station of annihilation (fana), where the illusion of the separate self dissolves in the reality of the Divine.
B. Journey Two: From the Truth to the Truth
Having transcended creation, the traveler now journeys within the Divine Essence, contemplating the Divine Names and Attributes. This stage includes Sadra's version of the Proof of the Truthful (Burhan al-Siddiqin), which proves God not from creation, but from the logical necessity of Existence itself. The journey culminates in the station of subsistence (baqa), where the traveler is reconstituted with Divine characteristics.
C. Journey Three: From the Truth to Creation
The traveler returns to the world of plurality, but now views it through the lens of divine unity. They see the universe not as a distraction but as a theophany—a mirror reflecting God's names. They understand the intricate hierarchies of being and the unfolding of Divine Will in the laws of nature, seeing the Face of God in every atom.
D. Journey Four: From Creation to Creation
In the final stage, the perfected traveler—the Perfect Human (Al-Insan Al-Kamil)—returns to society to guide others toward perfection. This journey encompasses practical wisdom, including psychology, eschatology (the nature of the afterlife, or Ma'ad), law, and politics. The goal is the elevation of all humanity, completing the cosmic cycle by bridging the finite self and the Infinite Truth.
V. Comparative Analysis of Ontological Systems
Feature | Greek Atomism (Democritus) | Kalam Atomism (Ash'ari) | Sadrian Theosophy (Mulla Sadra) |
Fundamental Unit | The eternal, solid, uncreated Atom. | The created, point-like singular substance (jawhar fard). | A specific intensity-degree of the singular reality of Existence (wujud). |
Nature of Substance | Static and immutable. Change is rearrangement. | Discontinuous. Destroyed and re-created by God every instant. | Fluid and dynamic. Substance is a process of continuous change. |
Cause of Motion | Mechanical Necessity (Anankē); collision and rebound. | God's direct and continuous will; there is no natural causality. | An intrinsic, teleological drive within substance itself to intensify and evolve. |
Status of the Void | Exists as non-being (kenon), essential for motion. | Accepted to separate atoms, but motion is a divine "placement." | Rejected. Reality is a plenum (a continuum) of graded existence. |
Nature of Time | A measure of atomic motion in the void. | A series of discrete, indivisible instants (ānāt). | The "fourth dimension" of matter; the quantitative measure of Substantial Motion. |
Metaphysical Goal | To explain nature without recourse to teleology or divinity. | To prove God's absolute power and the world's radical contingency. | To map the soul's evolutionary journey toward perfection and union with the Divine. |
The Sadrian Synthesis and the Rejection of Static Atomism
Your input text details the life and thought of Mullā Ṣadrā (Ṣadr ad-Dīn Muḥammad Shīrāzī). While Ṣadrā is a 17th-century thinker, his work represents a critical juncture in the reception history of Ancient Atomism and the Void. Ṣadrā does not adopt the atomism of Democritus or the kalām atomism of the Ash‘arites; rather, he deconstructs static ontology entirely in favor of dynamic gradation.
Core Thesis: Ṣadrā replaces the static "atom" ($atomos$) and the distinct "void" ($kenon$) with a continuum of Graded Existence ($tashkīk al-wujūd$) and Substantial Motion ($al-ḥaraka al-jawhariyya$).
The "Void" Problem: In Sadrian ontology, there is no absolute void ($khalāʾ$ or ‘adam maḥḍ); reality is a plenum of existence ($wujūd$) varying in intensity ($shidda/ḍu‘f$).
Lineage: His system synthesizes Aristotelian hylomorphism (matter/form), Neoplatonic emanation (Plotinus/Proclus), and Sufi metaphysics (Ibn ‘Arabī's Unity of Being).
1 Key Divergence: He rejects the Mutakallimūn (Islamic theologians) view of time as "atomic instants," proposing instead that time is the measure of substantial fluid motion.
Confidence: High regarding textual attestations in the Asfar; Medium regarding direct transmission lines from specific Presocratic fragments, which were likely mediated through doxographies (e.g., Pseudo-Ammonius).
Definition and Concept Framing
1. The Target Concept: Substantial Motion vs. Atomism
Ancient Atomism (Leucippus/Democritus) posits that reality consists of immutable particles ($atomoi$) moving in an empty void ($kenon$). Change is merely the rearrangement of these particles.
Mullā Ṣadrā’s Counter-Concept: Substantial Motion ($al-ḥaraka al-jawhariyya$). Ṣadrā argues that substance itself ($jawhar/ousia$) is not static. It is in a constant state of flux and becoming. Therefore, one cannot find an indivisible, static "atom" at the core of reality, nor a "void" separating them, but rather a continuous flow of being.
2. The Scope of "Void" (‘Adam / Khalāʾ)
For Ṣadrā, "Void" is conceptually linked to Non-Existence (‘adam). Since "Existence is the one and only reality" (Primacy of Existence), the Void has no ontological status—it is merely a mental abstraction representing the limit or absence of being.
Lexeme and Motif Map: From Greek to Arabic
The transition from Presocratic terminology to Sadrian Arabic involves complex translation movements (Greek $\to$ Syriac $\to$ Arabic).
| Language | Lemma / Transliteration | Literal Gloss | Conceptual Role in Tradition | Primary Refs |
| Greek | ἄτομος ($atomos$) | Uncuttable / Indivisible | The fundamental particle (Democritus). Rejected by Sadrā. | DK 68 B; Arist. De Gen. |
| Greek | κενόν ($kenon$) | Empty / Void | The container of atoms. Rejected by Aristotle & Sadrā. | DK 67 A; Arist. Phys. IV |
| Arabic | الجوهر (al-jawhar) | Jewel / Substance | Cognate to Greek ousia. Usually static; Sadrā makes it dynamic. | Asfar I.1; Shifā (Avicenna) |
| Arabic | الوجود (al-wujūd) | Finding / Existence | The sole reality. Replaces the "atoms" as the fundamental constituent. | Asfar I.1; Q. 2:115 |
| Arabic | العدم (al-‘adam) | Non-existence | The Sadrian equivalent of "Void" (non-being). Evil is defined as ‘adam. | Asfar I.3 |
| Arabic | الهباء (al-habā’) | Dust / Scattered motes | Quranic term often linked to atomism/materiality. | Q. 25:23 |
| Hebrew | תֹּהוּ וָבֹהוּ (tohu va-bohu) | Formless & Void | Biblical primordial chaos. Parallel to the Hayyūlā (Prime Matter). | Gen 1:2; Jer 4:23 |
Primary Attestations and Close Reading
1. The Presocratic/Hellenistic Backdrop (The View Rejected)
Democritus (DK 68 B 9): "By convention sweet and by convention bitter, by convention hot, by convention cold, by convention color; but in reality atoms and void ($atechnōs de atomoi kai kenon$)."
Philological Note: Sadrā encounters this view primarily through the critique of Aristotle and the Mutakallimūn. He accepts the reality of the external world (contra the sophists) but rejects the discrete nature of the atom.
2. The Sadrian Text (The Synthesis)
Source: Al-Ḥikma al-muta‘āliya fī-l-asfār al-‘aqliyya al-arba‘a (The Transcendent Theosophy in the Four Journeys of the Intellect), Vol 3.
"Existence ($wujūd$) is a single reality ($ḥaqīqa wāḥida$), graded in degrees of intensity and weakness ($bi-l-tashkīk$)... The motion of the substance is the renewal of the similitudes ($tajaddud al-amthāl*) appearing continuously."
Exegesis: Sadrā uses tashkīk (analogy/modulation) to solve the One and the Many. Instead of $X$ number of atoms making up a chair, the chair is a specific intensity of Existence.
The "Void" parallel: There are no gaps (voids) between degrees of existence, only gradations. Just as light fades to shadow without a hard line, existence fades toward non-existence (‘adam).
3. Quranic Substratum
Quran 27:88: "And you see the mountains, thinking them rigid, while they will pass as the passing of clouds ($wa-hiya tamurru marra al-saḥāb*)."
2
Reception: Sadrā frequently cites this verse as scriptural evidence for Substantial Motion. The world looks static (atomic/solid), but is actually in constant flux.
Comparative Analysis by Tradition
1. Presocratic & Platonic
Parallels: Sadrā’s system echoes Heraclitus (DK 22 B 12: "On those who step into the same rivers, different and again different waters flow"). Both prioritize becoming over being-static.
Divergence: Sadrā rejects the Democritean "Void." He aligns closer to the Stoic concept of pneuma (a tension field holding the universe together) and the Aristotelian plenum, though he radicalizes Aristotle by making the substance itself move, not just its accidents.
2. Neoplatonic & Hermetic
Neoplatonism: Sadrā is deeply indebted to the Theology of Aristotle (actually a paraphrase of Plotinus Enneads IV–VI). The concept of Emanation ($fayḍ$) is central.
Hermeticism: The input text notes Sadrā’s interest in "secret knowledge." The Hermetic principle "As above, so below" is reflected in Sadrā's unity of the intellect and the intelligible ($ittiḥād al-‘āqil wa-l-ma‘qūl$).
3. Abrahamic (Hebrew/Syriac/Arabic)
Creation: The standard Genesis/Quranic creation is ex nihilo.
Sadrian Reinterpretation: Sadrā interprets creation not as a moment in time (which implies a void before creation), but as an eternal dependence. The world is "temporally originated" ($ḥudūth zamānī$) in the sense that its being is fluid, constantly renewed by the Divine Breath (Nafas al-Raḥmān), akin to the continuous re-creation in certain Kabbalistic schools (e.g., the Zimzum of Lurianic Kabbalah, though the mechanisms differ).
Diachronic Timeline: The Transmission of "Motion" and "Void"
| Century | Source/Locale | Development | Transmission Status |
| 5th c. BCE | Abdera (Democritus) | Atomism established: Discrete particles + Void. | Rejected by Sadrā via Aristotle. |
| 4th c. BCE | Athens (Aristotle) | Plenum established: Rejection of void; Substance is static. | Modified by Sadrā (accepted plenum, rejected static substance). |
| 3rd c. CE | Rome/Alexandria (Plotinus) | Emanationism: Being is a graded light ($fos$). | Direct Influence (via Arabic trans). |
| 10th c. CE | Baghdad (Ash‘ari) | Occasionalism: God creates atoms/accidents every instant. | Critiqued by Sadrā as discontinuous. |
| 11th c. CE | Persia (Avicenna) | Essentialism: Essence ($mahiyya$) is distinct from existence. | Inverted by Sadrā (Primacy of Existence). |
| 12th c. CE | Aleppo (Suhrawardi) | Illuminationism: Reality is "Light of Lights." | Synthesized into Sadrā's ontology. |
| 17th c. CE | Isfahan/Shiraz (Sadrā) | Transcendent Theosophy: Substantial Motion + Primacy of Existence. | Culmination of the lineage. |
Textual and Manuscript Notes
The Asfar Tradition: The critical edition of the Asfar (ed. R. Lutfi et al.) relies on early Safavid manuscripts.
Variant Readings: In discussions of the "Void," Sadrā often engages with the term ‘adam. In early manuscripts, scribes sometimes conflate ‘adam (non-existence) with ẓulma (darkness/privation) in the margins, highlighting the Illuminationist influence where "Void" = "Absence of Light."
The "Khan School" Manuscripts: Manuscripts copied at the Khan School (Shiraz), where Sadrā taught, show heavy marginalia attempting to reconcile his radical "Substantial Motion" with orthodox Twelver Shi'a theology, indicating the controversial nature of his denial of static substance.
Scholarly Debates
1. Existentialism: Sadrā vs. Heidegger/Sartre
Debate: Western scholars (like Corbin) compare Sadrā to Heidegger.
Correction: As your input text notes, Sadrā's "existentialism" is cosmological, not anthropological. It is about the act of being ($esse$) of the Cosmos, not the angst of the human subject.
Philological Nuance: Sadrā’s aṣāla (primacy/fundamentality) is metaphysical. Heidegger’s Dasein is phenomenological.

2. The Nature of Time
Atomist View: Time is a sequence of "nows" (atomic instants).
Sadrian View: Time is the measure of the fluid transformation of substance. It is the "fourth dimension" of the body (long before Einstein, though purely metaphysical).
Conclusions and Confidence
Status of Atomism: Mullā Ṣadrā is definitively anti-atomist. He views the "atom" as a mental construct, not an external reality. Reality is a continuous, graded fluid of Existence.
Status of Void: He rejects the physical Void ($khalāʾ$) in favor of the metaphysical Non-Existence ($‘adam$) which serves as the "background" against which the intensity of God's Being is measured.
Transmission: Highly confident that Sadrā synthesized these views from a direct reading of Avicenna (Ibn Sīnā), Suhrawardi, and the Theology of Aristotle (Plotinus), reframing the ancient Greek "Problem of Change."
Executive Overview: Sadrā’s Deconstruction of the "Indivisible Part"
Mullā Ṣadrā’s refutation of the juz' alladhī lā yatajazzā (the indivisible part/atom) is a critical component of his physics found in the Asfar (specifically the Safar on Natural Philosophy). He does not merely repeat Peripatetic arguments but radicalizes them to prove his doctrine of Substantial Motion (al-ḥaraka al-jawhariyya).
His strategy utilizes Zeno’s Paradoxes of Plurality and Motion—not to prove that motion is impossible (as Zeno did), but to prove that discrete motion and discrete space are impossible. He argues that if reality were made of static atoms, Zeno’s paradoxes would hold true, and motion would be an illusion. Since motion is undeniably real (badīhī), the atomic premise must be false.
Lexeme Map: The Terminology of Refutation
| Language | Term / Transliteration | Literal Gloss | Conceptual Role in Sadrā’s Argument |
| Arabic | الجزء الذي لا يتجزأ al-juz' alladhī lā yatajazzā | The part that does not partition | The standard Kalām term for "atom." Sadrā targets this specifically. |
| Arabic | برهان التماس Burhān al-Tamāss | Proof of Contact | Sadrā’s primary geometric refutation (parallel to Zeno’s Paradox of Plurality). |
| Arabic | برهان السمت Burhān al-Samt | Proof of Direction/Alignment | A variant of Zeno’s Arrow/Stadium paradox regarding alignment during motion. |
| Arabic | الطفرة al-Ṭafra | The Leap / Jump | The specific absurd consequence (teleportation) that Sadrā argues atomism necessitates. |
| Arabic | الآن السيال al-ān al-sayyāl | The Flowing Now | Sadrā’s solution to Zeno: time is not atomic instants, but a flowing continuum. |
Primary Attestations: The Arguments
Sadrā employs three specific arguments in the Asfar (and his commentary on the Hikmat al-Ishraq) that directly utilize Zeno’s logic.
1. The Argument from Contact (Burhān al-Tamāss)
The Zenonian Logic: Paradox of Plurality (Argument from Denseness).
The Argument:
Sadrā asks us to imagine three atoms: A, B, and C, arranged in a line so that B is in the middle ($A-B-C$).
Does the side of B that touches A differ from the side of B that touches C?
Horn 1: If Yes (they differ), then B has distinct sides (a right side and a left side). Therefore, B is divisible. The "indivisible part" is divided.
Horn 2: If No (they are identical), then A and C are touching the exact same "point" of B. This implies that A, B, and C are all occupying the same coordinate. They have "interpenetrated" (tadākhul) rather than extended. The universe collapses into a single point.
Sadrā’s Verdict: Since the universe has extension (imtidād), the atomic premise leads to absurdity.
2. The Argument from Motion/Alignment (Burhān al-Samt / al-Taṭbīq)
The Zenonian Logic: The Paradox of the Moving Rows (Stadium Paradox).
The Argument:
Imagine two lines of atoms moving past each other.
Line 1: Atoms $X_1, X_2$
Line 2: Atoms $Y_1, Y_2$
If they move past each other, there must be a moment where $X_1$ is halfway past $Y_1$.
If time and space are atomic, there is no "halfway." $X_1$ must essentially "teleport" from being aligned with $Y_1$ to being aligned with $Y_2$ without ever passing the midpoint.
This necessitates The Leap (al-Ṭafra), a concept famously defended by the Mu'tazilite al-Naẓẓām but rejected by Sadrā as physically impossible.
3. The "Diagonal" Argument (Incommensurability)
The Zenonian Logic: Infinite Divisibility vs. Finite Magnitude.
The Argument:
If a square is made of $10 \times 10$ atoms, its side is 10 units.
Euclidean geometry dictates the diagonal is $\sqrt{10^2 + 10^2} = \sqrt{200} \approx 14.14$.
If the diagonal is made of atoms, it must be a whole number (you cannot have 0.14 of an atom).
Thus, atomism makes basic geometry impossible. Sadrā argues that denying geometry is to deny the evident order of the cosmos.
Sadrā’s Utilization of Zeno: The "Arrow" and the Solution
Sadrā treats Zeno’s Arrow Paradox most seriously.
Zeno's Arrow: At any single instant (ān), a moving arrow occupies a specific space equal to its size. If it occupies a space, it is at rest. If it is at rest at every instant, it never moves.
Sadrā’s Refutation: Zeno is correct if time is made of instants (ānāt).
The Sadrian Solution: Substantial Motion (al-ḥaraka al-jawhariyya).
Sadrā argues that "Time" is not a container filled with instants. Time is the measure of the flow of substance. There are no static "instants" in reality; they are only mental cuts (i'tibārāt dhihniyya) we make across the flow. The Arrow never "is" at any point; it is always "becoming."
Conclusion on Confidence:
High. Sadrā explicitly uses the Burhān al-Tamāss and the problem of Ṭafra (Leap) in the Asfar to dismantle the Ash'arite/Kalām atomism, directly mirroring Zeno’s paradoxes of plurality and the stadium.
Sadr al-Din al-Shirazi (Mulla Sadra), titled "The Transcendent Philosophy of the Four Journeys of the Intellect" (Al-Hikmat al-Muta'aliyah fi-l-Asfar al-'Aqliyyah al-Arba'ah).
The Foundations of Transcendent Wisdom
To understand the spiritual and intellectual voyage outlined in this work, one must first grasp the context of its author, Mulla Sadra (Sadr al-Din; sadr; chest/foremost/center). Writing in 17th-century Persia, Sadra achieved a monumental synthesis of the three previous dominant schools of Islamic thought: the rational Peripatetic philosophy, the intuitive Illuminationist school, and the mystical gnosis of Sufism. He unified these disparate strands into a cohesive system known as Al-Hikmah al-Muta'aliyah (Hikmah; h-k-m; wisdom/judgment) and (Muta'aliyah; 'a-l-w; transcendent/high).
This philosophy relies on three fundamental pillars.
The first is the Primacy of Existence, or Asalat al-Wujud (Wujud; w-j-d; finding/being/existence). Sadra argues that existence is the sole fundamental reality, while Mahiyyah (Mahiyyah; ma-huwa; what-it-is/quiddity), or essence, is merely a mental construct used to delimit reality.
The second pillar is the Gradation of Existence, or Tashkik (Tashkik; sh-k-k; gradation/ambiguity/doubt). Existence is not static; it acts as a single reality that differs in intensity and weakness, much like light varies from a dim candle to the blazing sun.
The third pillar is Substantial Motion, or Haraka Jawhariyya (Haraka; h-r-k; motion) + (Jawhar; j-w-h-r; substance/jewel). Unlike previous philosophers who believed motion only occurred in accidents (like color or position), Sadra posits that the very substance of the universe is in a constant state of flux and evolution toward perfection.
The First Journey: From Creation to the Truth
The spiritual wayfarer begins their odyssey within the realm of the material world, seeking to transcend the veil of plurality to reach the Divine Reality. This is the journey from the creature to the Haqq (Haqq; h-q-q; truth/reality/right). In this stage, the intellect engages in a rigorous ontological investigation. The traveler must strip away the illusions of independent essences to realize that all things are merely manifestations of a single, binding Existence.
Here, the intellect realizes that the world is not a collection of static objects, but a dynamic flow. Through Substantial Motion, matter evolves into vegetation, vegetation into animal consciousness, and animal consciousness into the human soul. The soul is bodily in its origination but spiritual in its survival. This phase requires the traveler to master the physical and metaphysical sciences, understanding the universe as a unified structure moving yearningly toward its Creator.
The culmination of this first journey is the attainment of the "station of annihilation" (fana). The traveler realizes that their own existence is virtually nothing compared to the absolute intensity of the Divine. The illusion of the separate self dissolves, and the wayfarer perceives only the blinding light of the Truth.
The Second Journey: From the Truth to the Truth
Having transcended the material realm, the wayfarer now travels within the Divine Essence itself. This is the journey "in the Truth by the Truth." The traveler no longer looks at creation but contemplates the Divine Attributes and Names. This stage is purely theological and mystical. The intellect moves from one Divine Name to another—from Mercy to Power, from Knowledge to Life—understanding how these attributes are unified in the singular Essence of God.
In this phase, Sadra presents his famous Burhan al-Siddiqin (Burhan; b-r-h-n; demonstration/proof) + (Siddiqin; s-d-q; truthful ones). Unlike other cosmological proofs that use the created world to prove a Creator (inferring fire from smoke), this "Proof of the Truthful" looks at Existence itself. Because Existence is a single reality without a second, and because it cannot not-exist, the necessary, infinite reality of God is proven through God Himself, without need for intermediaries.
The wayfarer achieves the "station of subsistence" (baqa). Having been annihilated in the first journey, the traveler is now reconstituted with Divine characteristics. They begin to see with God’s eyes and hear with God’s hearing, achieving a perfect knowledge of the Divine Unity (Tawhid).
The Third Journey: From the Truth to Creation
The journey does not end in mystical isolation. The wayfarer, now possessing the attributes of the Truth, must return to the world of plurality. This is the journey from the Truth to the Creature, but it is undertaken "with the Truth." The traveler does not fall back into the illusion that the world is separate from God. Instead, they view creation through the lens of their enlightened state.
This stage deals with God’s Acts and the hierarchy of emanation. The traveler witnesses how the Divine Reality cascades down through the Malakut (Malakut; m-l-k; dominion/kingdom), the angelic realms of intellect and souls, eventually manifesting as the physical universe. The traveler understands the "World of Command" and the intricate machinery of causality.
The traveler sees the universe not as a distraction, but as a theophany—a mirror reflecting God's names. They understand the laws governing the heavens and the earth, not just as physical mechanics, but as the unfolding of Divine Will. The wayfarer is no longer lost in the crowd of creation; they walk among creatures while their heart remains attached to the Creator, seeing the Face of God in every atom.
The Fourth Journey: From Creation to Creation
The final stage is the completion of the cycle. This is the journey from the Creature to the Creature, undertaken "with the Truth." This phase corresponds to the role of the Prophet or the Perfect Human (Al-Insan Al-Kamil). The traveler, having returned to society, now has the duty to guide others toward perfection. This journey focuses on Psychology, Eschatology, and Politics.
Sadra details the science of the Ma'ad (Ma'ad; '-w-d; return/place of return/resurrection). He explains the reality of the afterlife, arguing for a bodily resurrection that is "imaginal" in nature. The soul creates a body in the afterlife that befits its inner character—beautiful for the virtuous, and grotesque for the vicious.
The wayfarer acts as a spiritual guide, legislation giver, and moral compass. They apply the transcendent wisdom gained in the previous journeys to the practical realities of human life, law, and society. The ultimate goal is not just individual salvation, but the elevation of humanity. The traveler leads others through the gradation of existence, helping them traverse the path from the mineral state to the station of divine vicegerency.
Summary:
Mulla Sadra’s Four Journeys is a comprehensive map of the soul's evolution, merging philosophy with mysticism. It asserts that through the realization of the primacy and unity of existence, the human intellect can transcend the material world, realize the Divine Reality, and return to transform society, bridging the gap between the finite self and the Infinite Truth.

Comments:
[27:88: Cosmic Motion and Divine Precision]
This verse presents a striking eschatological or cosmological image: the apparent solidity of mountains contrasted with their actual, cloud-like fluidity. Classical exegesis (e.g., al-Ṭabarī, Ibn Kathīr) predominantly contextualizes this within the Yawm al-Qiyāmah (Day of Judgment), linking it to the blowing of the Trumpet (27:87) where mountains are uprooted and moved (cf. Q. 18:47; 78:20). However, the specific phrasing "artistry of Allah who perfected all things" (ṣunʿa Allāhi... ʾatqana) introduces a nuance of structural order often associated with the present creation, leading some contemporary exegetes to interpret this as a reference to the Earth's rotation, where mountains move with the planet while appearing stationary. Linguistically, the simile marra as-saḥāb (passing of clouds) evokes a silent, massive, externally driven motion, paralleling biblical imagery of divine theophany (cf. Psalms 97:4-5, "The mountains melt like wax"). Ultimately, the verse binds cosmic magnitude to moral accountability (khabīrun bimā tafʿalūn), asserting that the Creator of such precise mechanics is equally aware of human conduct.
