Al-Razi (Rhazes)

c. 854–925 CE · Physician-philosopher; empirical clinician; rationalist critic of prophecy

Medicine over metaphysics, experience over authority — reason alone suffices for the good life

Abu Bakr Muhammad ibn Zakariyya al-Razi (Latinised as Rhazes) was the greatest clinician of the medieval Islamic world and its most radical philosophical nonconformist. Born in Rayy (near modern Tehran), he directed hospitals in Rayy and Baghdad and produced some two hundred medical and philosophical works. His "Kitab al-Hawi" (Continens) is an enormous medical encyclopaedia that shaped European clinical practice for centuries after its twelfth-century Latin translation. Philosophically, al-Razi broke with the Neoplatonic-Aristotelian consensus of the falasifa on almost every front: he affirmed five eternal principles (God, Soul, Matter, Time, Space) rather than a single emanationist hierarchy; he rejected prophecy altogether, arguing that reason is distributed equally among all humans and needs no prophetic supplement; and he championed the authority of clinical experience and observation over textual tradition. His "Spiritual Medicine" (al-Tibb al-Ruhani) is a practical ethical guide modelled on Platonic and Galenic psychology, teaching the regulation of the passions through reason — the physician of the soul mirrors the physician of the body.

Empiricism 35%

Al-Razi is the strongest empiricist in the classical Islamic tradition. His clinical method — systematic observation, case histories, experimental testing of remedies — places him closer to modern empiricism than to the rationalist Neoplatonic tradition of al-Farabi and Ibn Sina.

"All that is written in books is worth much less than the experience of a wise doctor." (Kitab al-Hawi, introduction, paraphrase)
Rationalism 25%

Al-Razi insists that reason ('aql) is God's greatest gift to humanity and is sufficient for all moral and intellectual guidance — prophecy is unnecessary and divisive. This is the most rationalist position in medieval Islam.

"Reason is the ultimate authority; by it we distinguish truth from falsehood and the beneficial from the harmful." (The Spiritual Medicine, ch. 1, paraphrase)
Islamic Philosophy / Falsafa 15%

Al-Razi belongs to the falsafa tradition by method and milieu, though he dissents from its Neoplatonic mainstream. His five-eternal cosmology was attacked by the Isma'ili philosopher Abu Hatim al-Razi and by virtually every subsequent faylasuf.

"I do not oppose Aristotle and Galen to agree with them blindly, but because I have tested their claims against observation." (Doubts Concerning Galen, preface, paraphrase)
Atomism 15%

Al-Razi's cosmology of five co-eternal principles — including absolute space, absolute time, and prime matter composed of indivisible atoms — is an atomist cosmology closer to Democritus (via the kalam atomists) than to Aristotle's hylomorphism.

"Matter is composed of indivisible particles separated by void, and space and time are absolute and eternal." (On the Five Eternals, paraphrase from Biruni's report)
Platonism (Classical) 10%

The ethical framework of the Spiritual Medicine is Platonic: the tripartite soul (rational, spirited, appetitive), the governance of the lower parts by reason, the philosopher as physician of the soul.

"The rational soul must govern the appetitive soul as a rider governs his horse." (The Spiritual Medicine, ch. 1, paraphrase)

Internal Tensions

Al-Razi's rejection of prophecy placed him outside the mainstream of both Islamic theology and Islamic philosophy. The falasifa attacked his five-eternal cosmology as incoherent (how can five independent principles produce an ordered cosmos?), while the theologians attacked his denial of prophetic authority as blasphemous. His empiricism in medicine sat uneasily with his speculative cosmology — the five eternals are not empirically verifiable. The deepest tension: if reason is equally distributed and sufficient, why do humans persistently disagree?

⧖

I. Time

Al-Razi posits time as one of the five co-eternal principles — absolute, infinite, and independent of matter. Time is not created; it is a primary substrate within which events occur. Discrete grain follows from his atomism: time consists of indivisible instants. Non-deterministic because reason grants genuine moral freedom; no necessitarian emanation.

Attributes
Extent: Infinite Ontological Status: Substantival Grain: Discrete Freedom: Non-Deterministic Traversability: Linear Direction: Uni-directional Dimensionality: One
✦

II. Space

Absolute and infinite — one of the five eternals. Space (al-khala', the void) exists independently of bodies, contra Aristotle's relational account. Al-Razi's space is closer to Newtonian absolute space than to anything in the Peripatetic tradition.

Attributes
Extent: Infinite Ontological Status: Substantival Curvature: not engaged Dimensionality: Three Locality: not engaged
◉

III. Matter

Prime matter is eternal, composed of indivisible atoms separated by void. Matter is conserved — atoms are neither created nor destroyed; they rearrange. This atomist cosmology breaks with the hylomorphism of the mainstream falasifa.

Attributes
Extent: Infinite Ontological Status: Substantival Conservation: Conserved Dimensionality: Three Locality: Local
◎

IV. Observer

The human observer is an embodied rational soul endowed with reason ('aql) as its primary instrument. Knowledge is gained through sensory experience and rational reflection, not through prophetic illumination. Fallible retainment: al-Razi insists that even Galen and Aristotle err, and that all claims must be tested empirically. Individual social unit: each person possesses equal rational capacity.

Attributes
Time Instance: Single Space Instance: Single Knowledge Extent: Immediate Knowledge Retainment: Fallible Physicality: Embodied Agency: Active Number: Plural Metaphysical Agency: Personal
⚡

V. Energy

Al-Razi's five-eternal cosmology implies that the causal efficacy of God and Soul upon Matter is infinite and conserved. The soul's entanglement with matter (a kind of cosmic fall) drives the dynamics of the world; God intervenes by granting reason to free the soul from material attachment.

Attributes
Extent: Infinite Ontological Status: Substantival Conservation: Conserved Dispersibility: Irreversible
⧉

VI. Information

Knowledge is acquired through experience and is not guaranteed by any prophetic or emanationist mechanism — hence non-conserved. The individual soul, once freed from matter, returns to its original disembodied state; al-Razi's soteriology does not clearly preserve personal identity, hence personal conservation is non-conserved. Discrete granularity follows from the atomist framework.

Is the universe running out of usable energy?
The heat death of the universe — entropy maxed out, no further work possible — is among the more sobering implications of mainstream physics. Whether it is structurally inescapable depends on what kind of finitude the cosmos has.
Both time and matter are unbounded; 'running out' is misframed.
On this view, the cosmos has neither a temporal horizon nor a material exhaustion point. The framing of running out presupposes bounds that the cosmos doesn't have. Energy gradients perpetuate; new configurations emerge; the categories that make heat-death scary don't apply at the cosmic scale.
Roads not taken Time is unbounded but matter is finite; usable energy can fail without time failing. (47%) · Time both has and lacks bounds depending on the level you ask at; finitude is conventional. (26%) · The cosmos has bounds; heat death is a real horizon. (12%)
Distinctive · only 15% of schools agree (31/202)
Are natural resources fundamentally finite, or only practically so?
Whether we can grow our way out of resource constraints — or whether the cosmos sets limits the economy ultimately must obey — depends on what kind of finitude matter has.
Resources are practically inexhaustible on cosmic scales; terrestrial limits are engineering.
On this view, matter and time are both unbounded at the largest scales. Terrestrial resource limits are real engineering and political constraints but not metaphysical ones; the cosmos can in principle support whatever expansion intelligence is capable of.
Roads not taken Time goes on but matter is bounded; we are eventually constrained even with infinite time. (47%) · The finitude question is level-dependent; resource ethics happens at the level that constrains us. (26%) · Resources are finite in the strict sense; living well requires accepting the limit. (12%)
Distinctive · only 15% of schools agree (31/202)
Could we owe future generations more than is materially possible to provide?
If we owe future people a habitable planet and the material means to flourish, and the cosmos is bounded in ways that make those obligations impossible at some scale, the obligation and the possibility come apart. Where they come apart turns on what kind of finitude we live in.
Both time and matter are unbounded; we cannot in principle owe more than is possible.
On this view, the cosmos has the resources to support whatever flourishing future generations are capable of, given sufficient time and intelligence. The impossibility concern is misplaced; the real questions are about trajectories and choices, not about resource ceilings.
Roads not taken Time is unbounded but matter is not; we can owe more across long time than the matter can provide. (47%) · The owing-and-possibility question is level-dependent; we owe what is appropriate at the level we act on. (26%) · The cosmos is bounded; our obligations to future generations are bounded with it. (12%)

Do you really choose? The future is open and you are a genuine origin of it. 69% Are addicts responsible for their addiction? The addict could have chosen otherwise — that's why recovery is real. 69% Should we hold AI systems responsible for what they do? An AI without a free will is not the kind of thing that can be responsible. 69% How much weight do future people deserve? Future people are as real as you are — and their interests count for as much. 47% Is regret rational? The past is as real as the present; regret is a real attitude toward a real thing. 47% Do we owe extinct species something we cannot give them? Extinct species are as real as we are; they have standing. 47%

Is the world created from nothing? Yes — matter was created and is conserved as a real substance. 55% Is the physical world fully real? Yes — the physical world is fully real, mind-independent, persisting. 55% Does matter have intrinsic moral standing? Matter is morally considerable insofar as it is created or conserved good. 55% What is money? Money is a real institution with intrinsic features. 54% What is a nation? A nation is a real moral community with intrinsic character. 54% What makes someone male or female? Sex is a real biological kind with given content. 54% Should we edit the human germline?

Is reality fundamentally digital?
Pancomputationalism, Planck-scale quanta, simulation theory and Kabbalistic letter-mysticism all say yes — but for very different reasons. The rest of the atlas says no.
Yes — but divinely-discrete: divine letters, momentary cognitions, atomistic theism.
On this view, the world is at bottom discrete, but the units are not bare bits. They are divine names, momentary cognitions, karmic atoms, sacred letters — the elementary acts of a creating or ordering agency. Discreteness is real and fundamental, and so is the …
Roads not taken No — continuous divine sustaining act, the Tao that knows no joints, the One's self-disclosure. (44%) · No — continuous fields, classical limits, analog deep structure. (37%) · Yes — bits, quanta, computational substrate. (13%)
Distinctive · only 6% of schools agree (12/202)
Are there indivisible units of experience?
Whiteheadian actual occasions, Buddhist moments of mind, Kabbalistic letter-cognitions, IIT phi-units — or the unbroken Jamesian stream? The atomism of experience cuts across naturalism and theism alike.
Yes, theistic atomism — actual occasions, divine letters, momentary cognitions.
On this view, the atoms of experience are not bare quanta but agent-laden moments: Whiteheadian actual occasions in which subjectivity and the divine lure meet, Kabbalistic letter-cognitions in which divine names act, Buddhist Abhidharma moments of mind, tantric ksana. The discreteness is real and so …
Roads not taken No — continuous divine presence; consciousness is the unbroken witness. (44%) · No — continuous Jamesian stream, phenomenological lived time. (37%) · Yes — naturalist quanta of experience. (13%)
Distinctive · only 6% of schools agree (12/202)
Is memory stored or reconstructed?
Engrams and traces — or continuous re-narration each time you remember? The cognitive-science debate has a theological cousin: divine memory holding each hair, or the ancestors' continuous remembering.
Stored — in divine memory's discrete particulars, or in karmic-record units.
On this view, memory is held in discrete particulars by an agency: the Lord who knows each hair, the karmic ledger that records each act, the angelic scribe who writes each deed, the Kabbalistic letters that spell each soul. Storage is real; the storer is …
Roads not taken Held in continuous divine or ancestral remembering — neither stored discretely nor purely reconstructed. (44%) · Reconstructed — continuous re-narrating, no fixed engrams. (37%) · Stored — discrete engrams, traces, weights. (13%)
Distinctive · only 14% of schools agree (29/202)
What makes someone the same person over time?
When dementia hollows out memory, when a coma resolves with no recall, when you imagine being uploaded — the question of whether the surviving person is still you turns on what kind of thing the 'you' was to begin with.
There was never a fixed self to either preserve or lose.
On these views, what we call a self was always a stream of experience, a constructed narrative, a process — never a thing whose continuity could be the question. Dementia, upload, transformation, death are stages in a process, not events that either preserve or destroy …
Roads not taken You are your body — continuity is bodily continuity. (36%) · You are a soul — what persists through change is the non-bodily aspect. (29%) · You span moments — identity is a pattern that need not be located at a single now. (9%)
Distinctive · only 14% of schools agree (29/202)
Is the late-stage dementia patient still the person their spouse married?
Loss of memory, of recognition, of the cognitive patterns that made the person — does this end the person, or merely the person you knew? The answer turns on what makes someone who they are.
There was no fixed person to lose; care is owed to whoever is here.
On these views, the person their spouse married was never a fixed thing whose continuation could be tracked across time. There has always been a stream of experiences, a developing character, a construction. Dementia is one of the more visible changes in the process; the …
Roads not taken Same body, same person — even when the cognitive pattern has changed. (36%) · The soul persists; the cognitive change is the body's, not the person's. (29%) · The person is the pattern across moments — diminished pattern, diminished person. (9%)
30 mainstream positions
If a teleporter copied and destroyed you, would you have survived? There was no fixed you to either survive or fail to; the question is malformed. 14% Does history have a direction or meaning? History recurs in cosmic cycles. 16% Could causation work backwards? Causation runs one way — the arrow of time is real and structural. 68% Is the asymmetry between memory and anticipation a real feature of time, or just of us? The asymmetry is real because time itself has a real direction. 68% Is the arrow of time a real feature of the cosmos, or only of how we describe it? The arrow is real and structural; the asymmetry isn't an artifact of description. 68% Is environmental damage ever truly permanent? Damage is real and permanent on the relevant timescales. There is no recovery; there is only limitation. 66% Can a civilization recover from collapse? Civilizational complexity is hard to build and easy to lose; recovery is at best partial. 66% Does the second law of thermodynamics mean something morally? Entropy is what time is. The moral weight, if any, is the weight of working against the current. 66% Is truth universal, tradition-bound, situated, or constructed? Truth is mind-independent, universal, accessible in principle to all. 65% When does a person begin? A person exists from conception — when a new being comes into existence. 54% What is marriage? Marriage has a given form — it’s a kind of thing we recognize, not make. 54% What is our place in nature? Active in a real nature — we cultivate, steward, transform. 48% Should we colonize space? Cultivating worlds beyond Earth is the next form of stewardship. 48% Is genetic engineering of food stewardship or domination? Genetic modification is cultivation by other means. 48% Who is the moral primary — the individual, the community, the cosmos, the class, or the species? The discrete person is the moral primary. 40% What happens to "you" when you die? A soul continues into another mode of being. 37% Can prayer for someone far away affect them? Prayer reaches because God or a cosmic ordering acts on the prayed-for. 37% Are coincidences ever more than coincidence? What looks like coincidence is providence — there is no such thing as a real coincidence. 37% Are the dead morally present to the living? The dead are present through divine memory, communion of saints, or ancestor presence. 35% Is divine omniscience compatible with human freedom? The human observer is in time, but God's vantage is not — and foreknowledge is not foreordering. 33% Does meditation reveal something genuinely timeless? Meditation participates in a real eternity — divine or cosmic — that the bounded human observer ordinarily cannot reach. 33% Does prayer change God's mind? God sees from outside time; prayer doesn't change God's mind, but it is part of how providence is enacted. 33% Should we trust expert testimony when we can't verify it? Trust expertise whose conclusions a competent mind can in principle reproduce. 32% Is religious revelation a real source of knowledge? Revelation is evaluable by reason — and not above it. 32% Does an LLM 'know' the things it correctly produces? An LLM can produce correct outputs but not reason to them; useful, not knowing. 32% Could an AI have a mind that matters? No — minds are not the kind of thing we engineer. 30% Do animals have moral standing comparable to humans? Moral standing comparable to humans requires what only humans have. 29% Could a fetal brain organoid in a petri dish be conscious? Without ensoulment, an organoid is tissue, not a person. 29% Does environmental harm in another country bind me morally? Distance doesn't dilute obligation; communion of saints / divine relation spans the cosmos. 29% How is knowledge of reality produced? Through controlled empirical investigation. 17%

Is anything truly lost when someone forgets? Information is lost when a mind forgets; matter and energy continue, but the pattern is gone. 51% Does deleting your data online destroy something real? Information is genuinely lost when the substrate that hosted it goes; deletion really destroys. 51% Could the dead, in principle, be brought back? The information dissipates with the substrate; restoration is in principle impossible. 51% Is forgiveness ontologically possible? The offense is locally constituted by its substrate; when the substrate dissolves, the offense genuinely passes away. 51%
