In TWA Part 2, we saw how the Transcendental Argument for God (TAG) functions within Transcendental Worldview Analysis (TWA), with TAG’s Offense exposing non-Christian worldviews and its Defense presenting Christianity as the necessary foundation for intelligibility.
Now in Part 3, we unpack the Five Criteria of TWA which give us the structured lens through which you apply TAG in real conversations, worldview comparison, and apologetic engagement.
These criteria will sharpen your ability to:
- Diagnose worldview failures,
- Demonstrate the necessity of Christian theism,
- And dismantle assumptions with precision and consistency.
What Are These Criteria For?
TWA is about more than winning arguments; it’s about exposing whether a worldview can:
- Account for transcendentals (truth, goodness, logic, etc.),
- Justify the preconditions of intelligibility, and
- Provide a coherent, livable, and superior framework for reality.
Each of the five criteria targets a specific philosophical or existential test.
The Five Criteria of TWA
Criterion 1: Foundational Adequacy
Definition:
A worldview must provide a coherent and necessary metaphysical and epistemological foundation. This includes an account of ultimate reality (ontology/metaphysics) and of how knowledge of that reality is possible (epistemology). The foundation must be non-arbitrary, necessary, and structurally sufficient to sustain a worldview.
Guiding Questions:
- What is ultimately real in this worldview?
- Does it account for existence, causal order, and identity at the most basic level?
- How does it explain the possibility of knowledge and rational inquiry?
- Does it avoid brute facts and unjustified assumptions?
Includes:
- Metaphysics/Ontology: What ultimately exists, first principles of being, causal order, necessity vs. contingency.
- Epistemology: Reliability of reason, justification, possibility of knowledge.
- Structural Sufficiency: Whether the worldview’s foundation can bear the weight of further claims.
TWA Relevance:
If a worldview lacks an adequate metaphysical and epistemological foundation, it collapses before even reaching questions of morality, logic, or meaning.
Criterion 2: Intelligible Coherence
Definition:
A worldview must coherently account for the preconditions of intelligibility—those necessary truths, realities, and categories that make reasoning, knowledge, and discourse possible. Even if a worldview has a proposed foundation (Criterion 1), it fails if it cannot ground these conditions without contradiction or arbitrariness.
Guiding Questions:
- Can it ground the laws of logic as universal, immaterial, and invariant?
- Does it provide a basis for moral absolutes and duties?
- Can it explain meaning, purpose, language, and communication?
- Does it secure personal identity and continuity over time?
- Does it justify the reliability of induction and the uniformity of nature?
Includes:
- Logic
- Moral absolutes
- Knowledge and rationality
- External world and uniformity of nature
- Meaning, purpose, and language
- Personal identity
- Transcendentals as categories of thought and reality
TWA Relevance:
This criterion shifts from the structure (Criterion 1) to the fruit. A worldview may claim a metaphysical and epistemological foundation, but unless it delivers a coherent and justifiable account of intelligibility, it cannot sustain rational discourse or lived experience.
3. Internal Consistency
Definition:
A worldview must be logically self-consistent, avoiding contradictions, incoherent affirmations, or self-defeating claims.
Guiding Questions:
- Does this worldview affirm and deny the same thing?
- Are its truth claims logically compatible?
- Does it collapse under its own stated principles?
Includes:
- Logical consistency of core claims
- No violation of the law of non-contradiction
- No reduction to absurdity on its own terms
- Intra-systemic coherence
4. Existential Viability
Definition:
A worldview must be livable and congruent with real human experience, moral obligation, rational responsibility, and the human condition. It must avoid practical nihilism, reductionism, or incoherence with daily life.
Guiding Questions:
- Can someone live consistently with this worldview’s claims?
- Does it affirm or deny the existence of real moral responsibility, love, truth, and dignity?
- Does it align with how people actually live and think?
Includes:
- Practical livability
- Moral responsibility and freedom
- Human dignity and personhood
- Cognitive confidence (reason, language, memory)
- Harmony with our deepest intuitions and lived experience
5. Comparative Superiority
Definition:
Among all contending worldviews, one must be demonstrably superior in explanatory power, coherence, justification, and existential integrity. TWA aims not merely to show Christianity is consistent, but that it is uniquely necessary.
Guiding Questions:
- Does this worldview perform better than others on all the above criteria?
- Does it explain what others cannot — or collapse where others remain viable?
- Is the Christian worldview not only consistent, but exclusive in meeting the transcendental demands?
Includes:
- Comparative performance across all criteria
- Reductio of rival worldviews
- Positive justification for Christian theism
- Evidentiary support as a supplementary confirmation
- Unity of PoIs, evidence, and lived experience
Summary Table (Concise)
| # | Criterion | Focus | Core Concern |
| 1 | Foundational Adequacy | Accounting | Possession of the necessary categories |
| 2 | Intelligible Coherence | Justification | Preconditions of intelligibility |
| 3 | Internal Consistency | Logic | No contradictions or fallacious reasoning |
| 4 | Existential Viability | Practice | Real-world livability and alignment |
| 5 | Comparative Superiority | Evaluation | Outperforms all rival worldviews |
How to Use These Criteria
Together, these five tests form a transcendental framework:
- Use them to ask diagnostic questions in conversation.
- Use them to critique non-Christian worldviews (Offense).
- Use them to defend the coherence and necessity of the Christian worldview (Defense).
The criteria are not arbitrary. Every worldview must account for and satisfy them otherwise they would be incoherent, illogical, and/or impractical.
Conclusion: The Grid for Every Worldview
These five criteria give you a powerful tool for evaluating any worldview you encounter: atheism, Islam, Hinduism, moral relativism, progressive Christianity, etc. They help you stay grounded, stay consistent, and keep the conversation at the foundation, not just the surface.
In our next post (TWA Part4), we’ll explore how to use these criteria in conversation—how to do a transcendental critique, press internal inconsistencies, and reveal worldview dependency on the Christian system.
