Tradition: French Enlightenment

A portable Enlightenment — short, witty, polemical entries assaulting religious fanaticism and defending tolerance, reason, and natural rights

The Dictionnaire philosophique portatif (1764) is Voltaire's most concentrated mature work — a "portable" dictionary of 73 articles (later expanded to over 100) on theology, ethics, politics, and culture, designed to be readable in short doses and impossible to suppress because of its compact form. The articles cover topics from "Abraham" and "Atheism" to "Tolerance" and "Tyranny," with characteristic Voltairean wit, polemical sharpness against the Catholic Church, and defense of religious tolerance, freedom of thought, and rational natural-rights politics. Composed during the Ferney years when Voltaire had become the central figure of European Enlightenment, the work was condemned by the Sorbonne, burned by the Parlement of Paris (1765), and placed on the Index — and read everywhere despite all of it. The most concentrated statement of philosophical Enlightenment as a polemical and pedagogical programme.

The Dictionnaire is the most concentrated polemical statement of Enlightenment rationalism applied to politics, religion, and morals.

"Reason is the only torch we can light our way by; everything that is irrational is dangerous and should be examined with merciless suspicion." (Dictionnaire, article "Raison")

Voltaire is a Newtonian-Lockean empiricist; the articles on epistemology and natural philosophy defend empiricist principles against rationalist excess and against religious authority.

"All that we know we know through experience; whoever begins with abstract principles ends in contradictions." (Dictionnaire, article "Idées")
Deism 20%

Voltaire's mature religious position is deist: a creator God whose existence reason discloses, but no revealed religion, no priesthood, no inspired scriptures.

"If God did not exist, it would be necessary to invent him. But the God of the philosophers is not the God of the priests." (Dictionnaire, several articles)

Although polemically anti-clerical, the Dictionnaire's defense of religious tolerance and freedom of conscience is foundational for the broad liberal-theological tradition.

"Of all religions, the Christian is doubtless that which should inspire the most tolerance — yet hitherto Christians have been the most intolerant of all men." (Dictionnaire, article "Tolérance")

Voltaire's practical-meliorist orientation — judge religious and political institutions by their actual consequences for human welfare — is pragmatic-realist.

"Anything that wounds society is foreign to philosophy; whatever serves society is its natural object." (Dictionnaire, article "Philosophe")

The dictionnaire's scepticism — refusal of dogmatic certainty in matters where evidence does not warrant it — descends from the New Academic tradition Voltaire knew through Bayle.

"Doubt is not a comfortable state, but certainty is an absurd one." (Dictionnaire, attributed)
Realism 10%

Voltaire is realist about the historical-textual evidence for religious claims; his critique of biblical and ecclesiastical history operates by careful evidentiary scrutiny.

"To examine the holy books with the same impartial eye with which we read Livy or Tacitus is the duty of every rational reader." (Dictionnaire, article "Bible")

Internal Tensions

The Dictionnaire's sharpness made it a polemical-political event, not merely an intellectual one — it provoked condemnation, burning, and pursuit. Its enduring philosophical value vs. its dated polemical specifics is a continuing scholarly question; the Voltaire Foundation's ongoing critical edition has been recovering both dimensions.

Do you really choose?
If the brain is a physical system and physical systems are governed by laws, then every choice is also a chain of causes — which raises the question of what was really left to choose.
Choice is real within a determined order — agency and determinism aren’t opposites.
On this view, the future is determined and you are genuinely choosing. Those aren't contradictory because the determination runs through you rather than around you: your reasoning, deliberation, and assent are the way the determined outcome gets settled. Choice is what it feels like from …
Roads not taken The future is open and you are a genuine origin of it. (69%) · Choice is structural illusion — every event is fixed by the prior state. (10%) · Even if the universe is undetermined, you are not the chooser. (6%)

Are addicts responsible for their addiction?
Addiction looks from one angle like the textbook case of agency failing — a person doing what they don't, in any meaningful sense, want to do. From another angle it looks like agency at work in hard conditions. Which it is depends on what agency is.
The addict is genuinely responsible within a determined order.
On this view, the addict is acting within a determined order but is genuinely acting — making decisions, endorsing or resisting urges, seeking or refusing help. Responsibility attaches not because some uncaused choice happened, but because the addict is the kind of agent through which …
Roads not taken The addict could have chosen otherwise — that's why recovery is real. (69%) · The addict's behaviour is the outcome of causes; 'responsibility' is a useful fiction, not a metaphysical fact. (10%) · Even if the universe is undetermined, the addict isn't the chooser. (6%)

Should we hold AI systems responsible for what they do?
When an autonomous AI takes an action that harms someone, the question of who or what is responsible — the developer, the operator, the model itself — turns on whether the model is the kind of thing that can be a responsible agent.
The AI can be a genuine agent within determined conditions — and therefore genuinely responsible.
On this view, what makes a being responsible is not indeterminism but the kind of process the being is. An AI that deliberates, considers consequences, can be given reasons, and modifies its behaviour on reflection is doing what responsible agency is, even if its underlying …
Roads not taken An AI without a free will is not the kind of thing that can be responsible. (69%) · An AI's behaviour is fully determined by training and input; 'responsibility' applies if at all to its makers. (10%) · Neither AIs nor anyone else are the locus of free agency; the question is the wrong one. (6%)

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%)

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%)

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 …

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%)

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% 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% 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% What makes someone the same person over time? You are a soul — what persists through change is the non-bodily aspect. 29% Is the late-stage dementia patient still the person their spouse married? The soul persists; the cognitive change is the body's, not the person's. 29% If a teleporter copied and destroyed you, would you have survived? The soul accompanies the person; engineering can't transfer it. 29% Does environmental harm in another country bind me morally? Distance doesn't dilute obligation; communion of saints / divine relation spans the cosmos. 29%
