How Do the Six Philosophical Commitments Work Together


How Do the Six Philosophical Commitments Work Together


ChatGPT:

They form a single, internally coherent philosophical stack. Each commitment does a specific job. None is redundant. Remove one, and the structure collapses or degrades into relativism, determinism, or psychologism.


What follows is a clean systems-level account, not a survey.



---


1. Substance Dualism


What it secures: a genuine internal domain


Claim:

There are two irreducible kinds of reality:


Mental (rational, normative, choosing)


Physical (causal, extended, mechanistic)



Function in the system:

Substance dualism explains why judgment, assent, and choice are not physical events reducible to neural causation.


Without it:


Thought becomes brain activity


Judgment becomes computation


Responsibility becomes a fiction



Structural role:

Substance dualism grounds the internal/external distinction.

It explains why some things are up to you in principle.

2. Metaphysical Libertarianism


What it secures: real choice and real error


Claim:

Rational agents can genuinely choose among alternatives; choices are not fully determined by prior physical states.


Function in the system:

Libertarian freedom explains:


Why error is possible


Why responsibility is justified


Why correction makes sense



Without it:


False judgment is just malfunction


Moral responsibility evaporates


“Ought” reduces to conditioning



Structural role:

Metaphysical libertarianism activates substance dualism.

A non-physical mind that cannot choose is inert.



---


3. Ethical Intuitionism


What it secures: direct moral cognition


Claim:

Some moral truths are known immediately by rational insight, not inferred from consequences, culture, or emotion.


Function in the system:

Ethical intuitionism explains:


Why moral recognition is immediate


Why moral deliberation is not empirical


Why error feels like recognition gone wrong, not ignorance



Without it:


Morality becomes sociology


Norms become preferences


Moral reasoning never gets off the ground



Structural role:

Ethical intuitionism supplies the input channel for moral knowledge.



---


4. Foundationalism


What it secures: termination of justification


Claim:

Justification must bottom out in non-inferentially justified beliefs, or else reasoning is circular or infinite.


Function in the system:

Foundationalism explains:


Why moral knowledge is possible at all


Why intuition is not arbitrary


Why reasoning has stopping points



Without it:


Every moral claim requires another reason


Moral skepticism becomes unavoidable


Intuition collapses into assertion



Structural role:

Foundationalism stabilizes ethical intuitionism.



---


5. Correspondence Theory of Truth


What it secures: truth as answerability to reality


Claim:

A judgment is true if it corresponds to how things actually are, not merely to coherence, usefulness, or consensus.


Function in the system:

Correspondence explains:


Why judgments can be false


Why error matters


Why correction is meaningful



Without it:


Truth becomes internal consistency


Moral disagreement becomes incommensurable


“Right” means “fits the system”



Structural role:

Correspondence theory is the truth-condition of all judgments in the system.



---


6. Moral Realism


What it secures: objective moral facts


Claim:

There are stance-independent moral truths; moral claims describe reality, not attitudes.


Function in the system:

Moral realism explains:


Why moral disagreement is substantive


Why some actions really are wrong


Why reform, not accommodation, is required



Without it:


Ethics becomes expression


Blame becomes taste


Moral education becomes persuasion



Structural role:

Moral realism is the ontological commitment that makes the rest worth having.

How They Interlock (System View)


[Substance Dualism]

        ↓

[Metaphysical Libertarianism]

        ↓

[Responsible Rational Agency]

        ↓

[Ethical Intuitionism]

        ↓

[Foundational Moral Knowledge]

        ↓

[Correspondence Truth]

        ↓

[Moral Realism]


Each layer presupposes the one above it.

What the System Explains That Rivals Cannot


This stack explains, simultaneously:


Why judgment is internal and sovereign


Why error is blameworthy, not pathological


Why moral recognition is immediate


Why moral reasoning can terminate


Why disagreement is about truth, not preference


Why self-correction is rationally obligatory



No single commitment can do this alone.



---


Bottom Line


This is not an eclectic bundle.

It is a single integrated metaphysical-epistemic-ethical architecture.


Substance dualism gives you a mind


Libertarianism gives it freedom


Intuitionism gives it access


Foundationalism gives it structure


Correspondence gives it truth conditions


Moral realism gives it something to answer to



Remove any one, and the system degrades into either:


Determinism


Relativism


Expressivism


Skepticism


Or moral psychology dressed up as ethics



This stack does not soften morality.

It explains why morality can be strict, demanding, and correctable.
