On the Soul

Tertullian's 'De Anima' (c. 208-12) — the first Latin Christian treatise on psychology, against the Gnostic Hermogenes

Quintus Septimius Florens Tertullianus · c. 208-212 · Latin · Theological-psychological treatise (58 chapters)

Tradition: North African Latin patristics / proto-orthodox-Christian psychology

Tertullian's c. 208-12 'De Anima' — first Latin Christian treatise on the soul, against the Gnostic Hermogenes

Composed during Tertullian's Montanist period c. 208-12, 'De Anima' (On the Soul) is his fullest treatment of the nature of the human soul and the first sustained Latin Christian psychology. In 58 chapters, Tertullian defends the corporeality of the soul (against Gnostic-dualist conceptions), its single uniform substance (against Platonist tripartition), its origin via traducianism (each new soul as offspring of the parents' souls, not separately created), and its survival of bodily death. The treatise polemically engages Plato, the Stoics, and the Gnostic Hermogenes, and is a foundational document of Christian-philosophical anthropology.

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%)
6 mainstream positions
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 both has and lacks bounds depending on the level you ask at; finitude is conventional. 26% Are natural resources fundamentally finite, or only practically so? The finitude question is level-dependent; resource ethics happens at the level that constrains us. 26% Could we owe future generations more than is materially possible to provide? The owing-and-possibility question is level-dependent; we owe what is appropriate at the level we act on. 26%
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%
Observer · 37 dilemmas, all mainstream
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% 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% Should we trust expert testimony when we can't verify it? Defer to credentialed traditions; experts are the modern analog. 28% Is religious revelation a real source of knowledge? Revelation is the paradigm case of authoritative knowledge. 28% Does an LLM 'know' the things it correctly produces? An LLM has no soul to whom revelation could be addressed; the question doesn't apply. 28% Are there indivisible units of experience? — — Does history have a direction or meaning? — — How is knowledge of reality produced? — — Is memory stored or reconstructed? — — Is reality fundamentally digital? — — Is salvation, liberation, or fulfillment individual or communal? — — Is truth universal, tradition-bound, situated, or constructed? — — What kind of religious-theological authority does the tradition recognize? — — Who is the moral primary — the individual, the community, the cosmos, the class, or the species? — —
Information · 4 dilemmas, all mainstream
Is anything truly lost when someone forgets? Information is conserved — the personal pattern is held even when an individual mind loses it. 39% Does deleting your data online destroy something real? Information at the cosmic level isn't destroyed; deletion only obscures access. 39% Could the dead, in principle, be brought back? The information that constitutes a person is conserved; restoration is in principle possible. 39% Is forgiveness ontologically possible? The offense persists ontologically; forgiveness is real moral work, but it doesn't erase what was. 39%
