Here’s a set of technical explanations and reader-friendly notes for the symbolic logic in the content above, allowing a non-specialist to follow the reasoning without losing the rigor. We’ll move section by section, unpacking the notation and argument flow.


1. Language Domains – What the Symbols Mean

The document starts by defining the “language” of the formalization — essentially the symbols, constants, and predicates that will be used in the logical statements.

Variables and constants

  • G – the set of all proposed God-concepts. Each God-concept is represented by a variable like g or h.
  • s – a constant standing for the honest seeker (a person trying sincerely to figure out the truth).

Predicates (properties that can be true or false of a God-concept g)
Each predicate is a function that outputs true or false depending on g’s properties:

  • C(g)Coherence: g is internally logically consistent (no contradictions).
  • K(g)Consistency with record: g’s described actions or history don’t conflict with one another.
  • D(g)Desirability: allegiance to g promotes human well-being or trustworthiness.
  • O(g)Openness: g can be evaluated without restriction.
  • Cir(g)Circularity: g can only be evaluated by its own authority (self-referential).
  • W(g)Worthy of worship: g merits allegiance.
  • H(g)High-stakes: committing to g has major consequences for s.

Policy predicates

  • F(g) – Forbids questioning.
  • S(g) – Requires only its own standards.

Doxastic (belief-related) predicates

  • B(s,g) – s believes in g.
  • E(s,g) – s has evaluated g on all relevant dimensions.
  • P(s,g) – It is rationally permissible for s to believe in g.

Deontic operator

  • O_s φ – “The seeker ought that φ” (obligation relative to s).

2. Core Axioms / Premises – The Rules the System Assumes

Each P# is a premise; the logic builds from these.

  • P1 – If something is high-stakes, s ought to evaluate it.
  • P2 – All God-concepts are high-stakes.
  • P3 – If s has evaluated g, g must meet all the key conditions: coherence, consistency, desirability, openness, and non-circularity.
  • P4 – If g fails any of those conditions, it is not rationally permissible to believe in g.
  • P5 – Rational permission to believe requires that evaluation has taken place.
  • P6 – Worthy-of-worship concepts are open to independent evaluation. (Contrapositive: If g is not open, it’s not worthy.)
  • P7 – If s believes in g, then g must be worthy of worship.
  • P8a – If g forbids questioning, it’s not open to evaluation.
  • P8b – If g requires only its own standards, it’s circular.
  • P9 – If another God-concept competes with g, s ought to evaluate g.
  • P10 – Even if belief starts as “properly basic,” evaluation is still required later.

3. Immediate Derivations – Quick Consequences of the Premises

These are logical “shortcuts” the author derives without a full proof:

  • D1 – From P1 + P2: s ought to evaluate every God-concept.
  • D2 – From P5 + P3: Rational permission to believe requires the five conditions to hold.
  • D3a – From P8a + P4: Forbidding questioning removes openness → fails permission.
  • D3b – From P8b + P4: Requiring self-standards → circular → fails permission.
  • D4a – From contrapositive P6: Closed concepts are unworthy.
  • D4b – From P7: Belief presupposes worthiness → closed concepts block belief.
  • D5 – Summary norm: Evaluate all; failure of any key condition blocks rational permission.

4. Fitch-Style Proof – Step-by-Step Demonstration

This is a formal method showing exactly how the conclusions follow from the premises.

  • Goal 1 – Show (A) s must evaluate all g, and (B) if g fails any key condition, belief is impermissible.
    • Uses P2 + P1 to derive A.
    • Uses P4 directly to derive B.
  • Goal 2 – Show forbidding questioning or requiring self-standards defeats rational permission.
    • Forbidding → not open → fails P4 condition → no permission.
    • Self-standard → circular → fails P4 condition → no permission.
  • Goal 3 – Show forbidding questioning makes g unworthy and thus belief impossible.
    • Forbidding → not open → unworthy → fails belief-worthiness requirement.

5. Compact Sequent Summary – Condensed Logic Flow

  • Ought to evaluate all g (P1 + P2).
  • Any failure in the five conditions blocks permission (P4).
  • Forbidding or self-referentiality triggers such failures (P8a/b + P4).
  • Forbidding also destroys worthiness, which belief requires (P6 + P7).

6. “Properly Basic” Add-On – Handling Beliefs Held Without Evidence Initially

Some claim belief in God can start “properly basic” (not based on argument).
This framework says:

  • Even then, competing God-concepts (P9) and high-stakes status require evaluation.
  • P10 says evaluation must happen after belief onset.
  • Continued permission still depends on the five conditions (D2).

7. Plain-English Restatement

Any honest seeker ought to evaluate every proposed God-concept.
If the concept is incoherent, inconsistent with its record, undesirable, closed to scrutiny, or circular, then believing it is not rationally permissible.

  • The concept of the Holy Spirit’s indwelling is central to Christian belief, promising transformative experiences and divine insights.

  • This post exposes how Christian apologists attempt to escape the moral weight of 1 Samuel 15:3, where God commands Saul to kill infants among the Amalekites. It argues that the “hyperbole defense” is self-refuting because softening the command proves its literal reading is indefensible and implies divine deception if exaggerated.…

  • This post challenges both skeptics and Christians for abusing biblical atrocity texts by failing to distinguish between descriptive and prescriptive passages. Skeptics often cite descriptive narratives like Nahum 3:10 or Psalm 137:9 as if they were divine commands, committing a genre error that weakens their critique. Christians, on the other…

  • In rational inquiry, the source of a message does not influence its validity; truth depends on logical structure and evidence. Human bias towards accepting or rejecting ideas based on origin—known as the genetic fallacy—hinders clear thinking.

  • The defense of biblical inerrancy overlooks a critical flaw: internal contradictions within its concepts render the notion incoherent, regardless of textual accuracy. Examples include the contradiction between divine love and commanded genocide, free will versus foreordination, and the clash between faith and evidence.
