Prior and Posterior Analytics

Aristotle's major logical works — the systematic theory of syllogism and demonstrative science

Aristotle · c. 350 BC (the core logical works of the Organon) · Classical Greek · Two-part systematic treatise on logic

Tradition: Classical Greek philosophy / Aristotelian logic

The systematic theory of syllogism (Prior) and demonstrative science (Posterior) — Aristotle's major logical works at the heart of the Organon

The Prior Analytics and Posterior Analytics are Aristotle's major logical works, at the core of the Organon (after the Categories and On Interpretation, before the Topics and Sophistical Refutations). The Prior Analytics develops the systematic theory of the syllogism — the basic form of valid deductive argument, classified by mood and figure. The Posterior Analytics develops the theory of demonstrative science: the structure of scientific knowledge as syllogistic derivation from first principles, the requirements for proper demonstration (starting from premises that are necessary, true, and prior to and explanatory of the conclusion), the nature of induction and definition. The works founded Western logic and philosophy of science. The Prior Analytics remained the standard text of Western logic until Frege's nineteenth-century mathematical logic; the Posterior Analytics remains a major reference in philosophy of science.

The Analytics found Western logic and analytic philosophy of science. Frege, Russell, the broader analytic tradition develop from Aristotelian foundations.

"Aristotelian syllogistic as the foundation of Western logic." (Analytics, paraphrasing)
Rationalism 20%

Aristotle's confidence in the demonstrative-deductive structure of scientific knowledge is paradigmatically rationalist.

"Demonstrative-deductive structure of scientific knowledge." (Posterior Analytics, paraphrasing)
Realism 15%

A working metaphysical realism: real essences, real necessary relations, real scientific knowledge of demonstrable truths.

"Demonstration from necessary and explanatory premises." (Posterior Analytics, paraphrasing)
Catholic/Thomistic 15%

Medieval Catholic scholasticism develops directly from the Analytics. Aquinas's science is paradigmatically Aristotelian-demonstrative.

"Aquinas's Aristotelian-demonstrative science." (Analytics, paraphrasing the medieval reception)
Islamic Philosophy / Falsafa 10%

Falsafa develops from the Aristotelian logical tradition. Avicenna and Averroes wrote substantial commentaries on the Analytics.

"Falsafa engaging the Analytics." (paraphrasing)
Hylomorphism 5%

The Analytics presuppose the hylomorphic-substantialist metaphysics of the Categories and Metaphysics.

"Hylomorphic metaphysics presupposed in the logical analysis." (Analytics, paraphrasing)
Pragmatic Realism 5%

A complicated relation: subsequent pragmatic-realist philosophy of science engages Aristotelian demonstration critically (Dewey, the broader pragmatist tradition).

"Pragmatist engagement with Aristotelian science." (Analytics, paraphrasing)
Platonism (Classical) 5%

A complicated relation: Aristotle's demonstrative science engages and modifies Plato's dialectical method.

"Aristotelian demonstration as modification of Platonic dialectic." (Analytics, paraphrasing)

Internal Tensions

The Analytics' theory of demonstration has been sharply critiqued in modern philosophy of science (Hume on induction, Kant on the synthetic a priori, Popper's falsificationism, Quine's web of belief). Recent rehabilitations of Aristotelian science (Nussbaum, Lear, Charles) have engaged the Analytics constructively. The relation between the Prior and Posterior — formal logic vs philosophy of science — is itself a continuing interpretive theme.

How Prior and Posterior Analytics resolves each dilemma

51 resolved positions across 4 dimensions, including 3 distinctive where the majority of schools go the other way · 6 unaligned.

Each dimension is sorted so minority positions come first. Mainstream positions are folded into an expandable list.

Time · 9 dilemmas, all mainstream
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 universe running out of usable energy? Time is unbounded but matter is finite; usable energy can fail without time failing. 47% Are natural resources fundamentally finite, or only practically so? Time goes on but matter is bounded; we are eventually constrained even with infinite time. 47% Could we owe future generations more than is materially possible to provide? Time is unbounded but matter is not; we can owe more across long time than the matter can provide. 47%
Matter · 7 dilemmas, all mainstream
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? Human nature is a real biological kind given by reproductive biology or by creation; editing the germline transgresses what is given. 54%

Distinctive · only 6% of schools agree (12/202)
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%)
28 mainstream positions
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% 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% Does environmental harm in another country bind me morally? Moral obligation tracks the relations one is in; distance does matter, structurally. 50% 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% 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% What makes someone the same person over time? You are your body — continuity is bodily continuity. 36% Is the late-stage dementia patient still the person their spouse married? Same body, same person — even when the cognitive pattern has changed. 36% If a teleporter copied and destroyed you, would you have survived? Different body, different person — you died in the scanner. 36% 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%

Information · 4 dilemmas, all mainstream
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%
