The shortest comparison

Position | Fundamental reality | What is a local subject? | Physical world | Main unresolved problem | Inexternalist difference |
------------------------------- | ------------------------------------------------------------------------------ | ---------------------------------------------------------------- | -------------------------------------------------------------- | ---------------------------------------------------- | -------------------------------------------------------------------------------------------------------------- |
Analytic idealism | One universal phenomenal consciousness | Dissociated alter of cosmic consciousness | Appearance of mental processes across a dissociative boundary | Why dissociation produces genuinely private subjects | Local subjects are distinct concrete process-tokens; universal consciousness is unnecessary |
Advaita Vedānta | Nondual Brahman as pure consciousness | Apparent individual produced through ignorance/limiting adjuncts | Ultimately dependent appearance | Why appearance and plurality arise at all | Finite subjects and physical processes are real token organizations, not merely ignorance-produced appearances |

1. Difference from analytic idealism

rnardo Kastrup’s analytic idealism holds that universal phenomenal consciousness is all that ultimately exists; nature consists of patterns of excitation within it. The central individuation proposal is that personal minds are dissociated segments or “alters” of the universal consciousness. ([PhilArchive][1])

s architecture is:

\infty
rightarrow{\mathrm{dissociation}}
1,D_2,\ldots,D_n.

e physical body and brain are then generally understood as what an alter’s inner mental activity looks like from across a dissociative boundary.

erture Inexternalism instead says:

i^\ast
quiv
i.

e concrete embodied process is not merely the external appearance of an already individuated mental alter. It is part of what objectively constitutes and selects that subject.

Exact differences

Analytic idealism begins with one subject

\infty=\text{primary}.

cal subjects must be derived through dissociation.

Aperture Inexternalism begins with concrete processes

_1^\ast,O_2^\ast,\ldots}

e objectively individuated through causal and temporal closure.

does not deny a common ground, but it does not need one.

Analytic idealism makes the physical derivative from mentality

ext{physical world}
===================

ext{extrinsic appearance of mentation}.

Inexternalism makes “physical” and “phenomenal” modes of access

peratorname{Ext}(O_i^\ast)
==========================

ext{physical organization},

peratorname{Int}(O_i^\ast)
==========================

ext{experience}.

ither side is an image manufactured inside the other.

Analytic idealism has a dissociation problem

must explain why one phenomenal field divides into genuinely private fields and why those divisions correspond so precisely to organisms.

Inexternalism has an aperture-selection problem

must show that maximal closure really tracks phenomenal fields.

is is empirically sharper because it predicts that subject boundaries should move with concrete closure, not with an unexplained cosmic dissociation process.

Sharp distinction

oxed{
ext{Analytic idealism: bodies represent dissociated minds.}

oxed{
ext{Inexternalism: embodied apertures are the concrete}

oxed{
ext{tokens whose intrinsic existence is mindedness.}

2. Difference from Advaita Vedānta

vaita treats Brahman as nondual pure consciousness and ultimate reality. The individual self and world are understood through ignorance, superimposition, and limiting conditions; liberation consists in realizing the identity of ātman and Brahman. ([Stanford Encyclopedia of Philosophy][2])

s basic structure is:

ahman
idyā/upādhi
ightarrow
ext{apparent individual and world}.

erture Inexternalism rejects three Advaitic commitments.

First: finite individuality is not merely apparent

r Inexternalism:

i\neq D_j

a real token distinction.

e subjects may share a type or underlying ontological character, but their privacy is not simply ignorance of an already existing identity.

Second: the physical world is not māyā in the deflationary sense

e world is a real network of concrete processes.

s extrinsic description is incomplete with respect to intrinsic existence, but it is not merely false appearance.

Third: liberation does not reveal numerical identity as a theoretical necessity

transformation may weaken:

narrative ego;
ownership;
rigid self–world division;
value fixation.

t that phenomenological transformation does not prove:

i=D_j=Brahman.

Sharp distinction

oxed{
ext{Advaita: plurality is ultimately sublated in nondual}

oxed{
ext{pure consciousness.}

oxed{
ext{Inexternalism: plurality is real at the level of}

oxed{
ext{concrete process-tokens, even if intrinsic existence}

oxed{
ext{has a common general nature.}

externalism is therefore non-reductively monist, but not necessarily existence monist.

ere may be one kind of reality without there being only one subject.

3. Difference from Pratyabhijñā

is is the closest nondual relative.

atyabhijñā regards ultimate reality as one self-manifest, freely creative consciousness—Śiva. Finite selves are contractions of its powers, and the world is a real manifestation rather than a mere illusion. It differs from Advaita precisely by emphasizing consciousness’s freedom, activity, and genuine world manifestation. ([Wikipedia][3])

s structure is:

\infty
rightarrow{L_i}
i,W_i,

ere (L_i) is contraction.

erture Inexternalism retains almost the complete finite architecture:

egin{aligned}
ext{jñāna}&\rightarrow\text{manifest discrimination},\
ext{smṛti}&\rightarrow\text{retention},\
ext{apohana}&\rightarrow\text{determination},\
ext{anusandhāna}&\rightarrow\text{connective synthesis},\
ext{vikalpa}&\rightarrow\text{counterfactual generation},\
ext{rāga}&\rightarrow\text{value weighting},\
ext{deha-bheda}&\rightarrow\text{embodied individuation},\
ext{pratibimba}&\rightarrow\text{inter-stream influence}.
nd{aligned}

t it suspends the universalization:

i,D_j
ext{ possess the same type of intrinsic nature}

es not prove:

i=D_j=C_\infty.

Exact point of separation

Pratyabhijñā

oxed{
ext{All local manifestation is numerically the activity}

oxed{
ext{of one universal subject.}

Inexternalism

oxed{
ext{Each local aperture is a numerically distinct token}

oxed{
ext{whose intrinsic nature is manifest, reflexive,}

oxed{
ext{temporally unified, and valenced.}

common manifest ground remains an optional extension:

i=\pi_i(M_0),

t part of the minimal theory.

Why this matters

atyabhijñā solves the hard problem by making consciousness fundamental.

t it does not fully solve the decomposition problem:

oxed{
ext{Why does one universal consciousness generate genuinely}

oxed{
ext{private fields that cannot perform connective synthesis}

oxed{
ext{across one another?}

externalism answers with concrete aperture boundaries rather than cosmic self-contraction alone.

4. Difference from Yogācāra

gācāra analyses experience through cognition-only or representation-only doctrines, dependent construction, karmic seeds, and multiple causally continuous cognitive processes. It is often misrepresented as simple universal-mind idealism; major interpretations instead emphasize an analysis of cognition and the absence of independently existing subject–object duality. ([Stanford Encyclopedia of Philosophy][4])

e closest convergence is:

oxed{
ext{the experienced world is actively structured rather}

oxed{
ext{than passively copied from a finished external object.}

t Inexternalism differs in four ways.

It affirms a concrete subject process

gācāra generally rejects a permanent substantial self.

externalism agrees that the subject is not an immutable substance, but posits:

i^\ast
======

ext{a real, temporally persistent process-token}.

It preserves a real extrinsic world

e external world is not simply representation.

is the extrinsically accessible relational structure of concrete processes.

It treats intrinsic nature as phenomenal

gācāra can explain the construction of objectivity without settling contemporary intrinsic–extrinsic identity.

externalism adds:

peratorname{Int}(O_i^\ast)=D_i.

It gives embodiment stronger individuating force

erture boundaries are selected through embodied memory, value, and reciprocal control—not karmic stream-continuity alone.

Sharp distinction

oxed{
ext{Yogācāra: subject and object are dependently constructed}

oxed{
ext{within cognitive streams.}

oxed{
ext{Inexternalism: one concrete process is intrinsically}

oxed{
ext{a cognitive-phenomenal stream and extrinsically an}

oxed{
ext{embodied causal organization.}

5. Difference from Russellian monism

ssellian monism is perhaps the nearest contemporary analytic position. It argues that physics describes structural, relational, or dispositional features while leaving the intrinsic or categorical nature of matter unspecified. A single underlying set of properties may ground both consciousness and the entities described by physics. ([Stanford Encyclopedia of Philosophy][5])

s generic form is:

ext{physics}
============

ext{extrinsic structure},

ext{consciousness}
==================

ext{clue to intrinsic nature}.

erture Inexternalism strongly agrees with:

oxed{
ext{extrinsic physical description does not exhaust}

oxed{
ext{the intrinsic nature of concrete reality.}

t it differs from many Russellian views in three ways.

1. It is macro-process-first, not micro-property-first

ssellian panpsychist forms often place phenomenal or proto-phenomenal categorical properties at the microphysical base.

en they face:

ext{How do micro-intrinsics combine into one subject?}

externalism instead says:

oxed{
ext{subjecthood belongs to the maximal concrete closure,}

t to each microcomponent.

e components need not be micro-subjects.

2. It identifies the intrinsic nature of an organized token

e intrinsic side is not assigned separately to each elementary constituent and then assembled.

belongs to:

i^\ast

one causally active process.

3. It adds an explicit individuation criterion

ssellian monism is primarily an account of what physics leaves out.

erture Inexternalism additionally asks:

oxed{
ext{Which exact physical whole has an intrinsic side}

oxed{
ext{constituting one subject?}

s answer is maximal aperture closure.

Sharp distinction

oxed{
ext{Russellian monism: consciousness reveals the intrinsic}

oxed{
ext{nature underlying physical structure.}

oxed{
ext{Aperture Inexternalism: the intrinsic phenomenal token}

oxed{
ext{is the intrinsic existence of a specifically selected}

oxed{
ext{macro-process, not a sum of micro-intrinsics.}

is makes Aperture Inexternalism a macro-Russellian process monism.

6. Difference from dual-aspect monism

al-aspect views say that mental and physical are two irreducible aspects of one underlying reality.

neric form:

ightarrow
egin{cases}
{\mathrm{mental}},\
{\mathrm{physical}}.
nd{cases}

erture Inexternalism resembles this but rejects the implication that a third neutral substance (X) stands behind both aspects.

s structure is:

i^\ast
======

egin{cases}
peratorname{Int}(O_i^\ast)=D_i,\
peratorname{Ext}(O_i^\ast)=\Sigma_i.
nd{cases}

hysical” and “phenomenal” are not two properties displayed side by side.

ey are two epistemic orientations toward the same event:

extrinsic relational access;
intrinsic existence.

Why this is more precise

aditional dual-aspect theory often leaves unanswered:

Which entities have both aspects?
At what scale?
Why is one aspect unified?
Why does one body correspond to one mind?

erture Inexternalism supplies:

i^\ast
======

peratorname{MaxClosure}
eft(
ext{memory},
ext{value},
ext{generation},
ext{determination},
ext{control}
ight).

Sharp distinction

oxed{
ext{Dual-aspect monism says reality has two aspects.}

oxed{
ext{Inexternalism says one selected process has an}

oxed{
ext{intrinsic existence and an extrinsic relational profile,}

oxed{
ext{and specifies what selects that process.}

is therefore best understood as asymmetric dual-access monism, not generic dual-aspect monism.

e access is asymmetric because:

peratorname{Ext}(O_i)
ot\vdash
peratorname{Int}(O_i),

though they are numerically identical.

7. Difference from neutral monism

utral monism says ultimate reality is of one kind that is intrinsically neither mental nor physical; mental and physical phenomena are constructed or organized from that neutral basis. ([Stanford Encyclopedia of Philosophy][6])

neric form:

ightarrow
egin{cases}
ext{mental organization},\
ext{physical organization}.
nd{cases}

erture Inexternalism rejects neutrality at the subject level.

r a conscious aperture:

peratorname{Int}(O_i^\ast)

not neutral between experience and non-experience.

is experience.

at remains neutral is only the general ontology of process before the subject-selection condition is satisfied.

oxed{
ext{all reality may be processual,}

oxed{
ext{only some maximal processes are intrinsic phenomenal}

oxed{
ext{centres.}

Sharp distinction

oxed{
ext{Neutral monism: the basic stuff is neither mental}

oxed{
ext{nor physical.}

oxed{
ext{Inexternalism: physicality is extrinsic description;}

oxed{
ext{for conscious apertures, intrinsic existence is}

oxed{
ext{positively phenomenal rather than neutral.}

8. Difference from Whiteheadian process philosophy

ocess philosophy makes becoming, activity, and event-like entities fundamental rather than static substances. In Whitehead’s system, basic “actual occasions” are integrations of prior conditions; Whitehead’s metaphysics attributes physical and mental poles to actual entities and treats human consciousness as a higher form rather than the only form of mentality. ([Stanford Encyclopedia of Philosophy][7])

is is extremely close in ontology:

oxed{
ext{reality consists fundamentally of events and processes.}

t there are decisive differences.

Whitehead is panexperiential

perience or mentality reaches down to fundamental actual occasions.

erture Inexternalism does not require:

ext{every basic event has its own experience}.

Whitehead builds macro-organisms from societies of occasions

is raises a version of the combination problem:

ext{How do many occasions constitute one human field?}

externalism reverses the priority:

oxed{
ext{the maximal aperture is the primary phenomenal token.}

s parts are constitutive physical processes but need not remain independent subjects.

Whitehead’s occasions are highly momentary

erture Inexternalism places more emphasis on temporally extended closure:

amma_i
athcal M_i
athcal C_i.

subject is not merely a succession of experiential atoms; it is one persistent mnemonic, evaluative, counterfactual regime.

Sharp distinction

oxed{
ext{Whitehead: reality is composed of experiential}

oxed{
ext{micro-events that form societies.}

oxed{
ext{Inexternalism: reality is processual, but subjecthood}

oxed{
ext{appears only at maximal, temporally extended}

oxed{
ext{aperture closure.}

is therefore process monism without panexperiential atomism.

9. Difference from panpsychism and cosmopsychism

Against constitutive panpsychism

npsychism assigns consciousness or proto-consciousness to fundamental physical entities and attempts to explain macro-consciousness through combination. The standard problem is how many micro-experiences combine into one unified subject. ([Stanford Encyclopedia of Philosophy][8])

externalism says:

oxed{
ext{intrinsic nature}
eq
ext{micro-subjecthood}.

neuron, molecule, or particle can be part of the concrete realization without possessing a separately bounded phenomenal field.

e phenomenal subject is:

i^\ast,

um_k D_k^{\mathrm{micro}}.

Against cosmopsychism

smopsychism begins with one cosmic subject and derives local subjects through decomposition.

externalism begins with local maximal closures.

remains agnostic about whether reality as a whole has an intrinsic phenomenal unity.

Sharp location

oxed{
ext{Inexternalism lies between micro-panpsychism}

oxed{
ext{and cosmopsychism: intrinsic nature is fundamental,}

oxed{
ext{but subjecthood is aperture-relative and locally selected.}

10. Difference from standard physicalism

ysicalism usually says that all facts, including consciousness facts, are fixed or constituted by physical facts.

erture Inexternalism can accept token physical identity:

i=O_i^\ast,

ile rejecting the completeness of “physical” when physical means exclusively:

structural;
relational;
behavioural;
third-personal.

says:

oxed{
ext{physics describes what the process does and how it}

oxed{
ext{relates; experience is how that same process exists}

oxed{
ext{intrinsically.}

is therefore not anti-physical.

is anti-extrinsic-definition physicalism.

e theory could be called:

oxed{
extbf{intrinsic process physicalism}

ovided “physical” is expanded beyond public relational description.

t “inexternalism” is clearer because it emphasizes that:

ext{inside and outside are neither separate substances}

ext{two externally visible aspects}.

ey are the same token approached through different access relations.

11. The exact coordinate of the theory

erture Inexternalism combines five commitments:

Ontological monism

ere is one category of concrete reality:

ext{process}.

Epistemic dual-access

ncrete processes may be known:

ext{extrinsically}

exist:

ext{intrinsically}.

Phenomenal token identity

r conscious apertures:

peratorname{Int}(O_i^\ast)=D_i.

Process individuation

bjects are selected by maximal closure:

i^\ast
======

peratorname{MaxClosure}
eft(
athcal M,
athcal V,
athcal I,
athcal E,
athcal C,
amma,
ight).

Non-universalist pluralism

stinct closures yield distinct subjects:

i^\ast\neq O_j^\ast
ightarrow
i\neq D_j.

inference to one cosmic subject is required.

Its nearest philosophical formula

e most exact description is:

oxed{
extbf{Aperture Inexternalism is a non-panpsychist,}

oxed{
extbf{macro-Russellian, process-based, dual-access}

oxed{
extbf{identity monism with real phenomenal pluralism.}

ch modifier matters:

non-panpsychist: not every entity is a subject;
macro-Russellian: intrinsic nature belongs to selected macro-processes rather than being assembled from micro-subjects;
process-based: events and trajectories, not substances, are primary;
dual-access: intrinsic and extrinsic are modes of access, not separate properties;
identity monism: mind and physical aperture are one token;
phenomenal pluralism: subjects are genuinely multiple and private.

Final positional statement

Aperture Inexternalism holds that reality is composed of concrete processes rather than mental or material substances. A conscious subject is a maximally closed, embodied, temporally persistent process whose intrinsic existence is one private, valenced phenomenal field and whose extrinsic profile is the physical organization studied by science. Local minds are genuinely distinct process-tokens, not dissociated fragments, illusory selves, combinations of micro-subjects, or appearances inside one cosmic mind. Universal consciousness is permitted as a further hypothesis but is not required by the core theory.

at places the theory closest to:

oxed{
ext{Russellian monism}
ext{process philosophy}
ext{dual-access identity theory}

t with the crucial additions:

oxed{
extbf{maximal-closure subject selection}
extbf{real phenomenal plurality}.

ose two additions are what make it a distinct position rather than a renaming of an existing monism.
