A Treatise of Human Nature
Hume's first major philosophical work in three books — on understanding, the passions, and morals

Reason is and ought to be the slave of the passions — and the most rigorous Newtonian science of human nature
A Treatise of Human Nature is Hume's first major philosophical work and the most systematically developed statement of his philosophy. Published anonymously when Hume was 28, the work develops in three books: Book I (Of the Understanding) presents his empiricist epistemology, the famous critique of induction, the bundle theory of personal identity, and the scepticism about external objects; Book II (Of the Passions) analyses human emotional life; Book III (Of Morals) develops a sentimentalist moral philosophy with the famous distinction of "is" from "ought." Hume famously reported that the Treatise "fell dead-born from the press"; he later reworked its content into the more accessible Enquiry Concerning Human Understanding (1748) and Enquiry Concerning the Principles of Morals (1751). Modern philosophy has recovered the Treatise as Hume's most ambitious work.

School Embodiments
Empiricism
40%
The Treatise is the most rigorous classical British empiricist work. Locke and Berkeley supplied premises; Hume drew the conclusions.
"All the perceptions of the human mind resolve themselves into two distinct kinds, which I shall call IMPRESSIONS and IDEAS." (Treatise I.I.1)
Phenomenalism
15%
The bundle theory of the self and the analysis of external objects as constancy of impressions are the most rigorous early statements of phenomenalism.
"I never can catch myself at any time without a perception." (Treatise I.IV.6)
Pyrrhonism
15%
The Treatise's mitigated scepticism — suspending judgement on metaphysical questions while following custom in practice — is the most rigorous modern revival of Pyrrhonism.
"Nature has determined us to judge as well as to breathe and feel." (Treatise I.IV.1)
Naturalism
15%
The Treatise programmatically applies the Newtonian-empirical method to human nature; this is one of the founding projects of modern philosophical naturalism.
"Reason is, and ought only to be, the slave of the passions." (Treatise II.III.3)
Constructivism
10%
Hume's moral sentimentalism — morality is rooted in feeling rather than reason — has been read by modern constructivists as a precursor of socially-constituted moral epistemology.
"Vice and virtue may be compared to sounds, colours, heat and cold, which are not qualities in objects, but perceptions in the mind." (Treatise III.I.1)
The Vienna Circle read Hume as a major precursor; the is/ought distinction and the verificationist instinct both descend from him.
"In every system of morality... the author proceeds for some time in the ordinary way of reasoning... when of a sudden I am surprised to find that instead of the usual copulations of propositions, is and is not, I meet with no proposition that is not connected with an ought." (Treatise III.I.1)
Internal Tensions
The Treatise's alternation between rigorous scepticism and endorsement of common-sense belief was acknowledged by Hume himself ("having taken a glass of wine and played a game of backgammon, I find these speculations cold and strained"). The relation between books I, II, and III — whether the moral philosophy presupposes the epistemology or stands independently — has been the subject of major scholarly debate (Stroud, Norton, Garrett).

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 …

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 …

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 …

An AI without a free will is not the kind of thing that can be responsible. (69%) ·

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.

Time is unbounded but matter is finite; usable energy can fail without time failing. (47%) ·

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.

What is money?
The question of what money is — a measured store of real value, an agreed-on practice, a relational ledger of debts, or just a name we apply to many different things — sits behind every argument about inflation, cryptocurrency, debt, and the state.
“Money” names a family of practices — the definition question is nominal.
On this view, gold, fiat currency, cryptocurrency, frequent-flyer miles, prison cigarettes, and the IOUs scribbled on a bar napkin are not all the same kind of thing. They share family resemblances but no common essence. Trying to define money univocally is asking a question that …

What is a nation?
Whether a nation is a real moral community with intrinsic character, a constructed legal-political artifact, a web of kinship and shared history, an imagined community, or a conventional partition of a deeper unity — these are real ontological positions with sharply different political downstream.
“Nation” names a family of practices imaginatively held together.
On this view, what we call nations are large-scale imagined communities — necessarily imagined because their members will never meet most other members, necessarily imagined as bounded and sovereign. The imagination is real and consequential; the underlying kind is not.

What makes someone male or female?
Whether sex is a real biological kind, a constructed social category, a relational identity, a label applied to varied phenomena, or a conventional distinction within a deeper unity is the ontological question the contemporary dispute about gender is mostly about.
“Male” and “female” are family-resemblance terms — no single essence.
On this view, the everyday categories of male and female pick out overlapping clusters of features — anatomy, physiology, social role, self-understanding, behaviour — that do not reduce to a single essence. The categories are useful but lossy; the demand for a single definition is …

Should we edit the human germline?
Whether human nature is a given biological kind, a constructed category, a relational achievement, a family-resemblance cluster, or a conventional distinction within deeper unity is the ontological question the policy debate over heritable gene editing is mostly about.
'Human nature' is a cluster term without a single essence; the editing question is empirical, not metaphysical.
On this view, 'human nature' picks out an overlapping cluster of features — anatomical, developmental, cognitive, social — without a single essence the cluster reduces to. The question of whether germline editing is permissible doesn't turn on transgressing an essence (there isn't one) but on …

Is the world created from nothing?
Creatio ex nihilo is one of the most distinctive Western-theological claims. Whether matter was created from nothing, eternally exists, or is sustained moment-by-moment turns on what kind of thing matter is.
Matter is constituted by relations; the question of 'from what?' presupposes substance.
On this view, matter is not a stuff but a patterning — the standing relations among things, ancestors, processes, and places. The creatio-ex-nihilo question doesn't quite arise, because the ontology has no slot for a free-standing substance to be created or eternal. What persists is …

When does a person begin?
The political question of abortion sits atop an older ontological one: at what point does there exist a someone — a being with moral standing — rather than merely the materials from which one will form?
The question presupposes a fact of the matter that isn’t there.
There is no point at which an unchanging core "comes into being"; there is a stream of conditioned arising that we choose to mark, or not mark, at various places. The political and moral question of how to treat developing humans is real; the metaphysical …

What is marriage?
Behind every disagreement about how marriage should be defined is a prior disagreement about what kind of thing it is — a given order to be recognized, a practice to be negotiated, or a web of relations to be woven.
“Marriage” names a family of practices — the definition question is nominal.
On these views, “marriage” is a name applied to many overlapping but distinct social configurations across cultures and across history. To ask “what is marriage, really?” is to ask a question that doesn’t have a single answer — because there isn’t a single thing whose …

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 — bits, quanta, computational substrate.
On this view, the world is at bottom discrete and law-governed, with no metaphysical agency above or behind the substrate. Reality reduces to bits or their physical analogues; the continuous appearance of fields and flows is coarse-graining over discrete underlying structure.

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 — naturalist quanta of experience.
On this view, experience comes in discrete units defined by the substrate: information-theoretic phi-units, computational frames, discrete neural events. There is no further metaphysical agency that knits them; the appearance of a stream is the way many discrete events present to introspection.

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 — discrete engrams, traces, weights.
On this view, memory is the readout of discrete information stored in the substrate: engrams, synaptic weights, file-like records. Reconstruction at retrieval is real but secondary; without the stored bits there would be nothing to reconstruct from.
