LOGIC, ABSTRACTION, AND THE GROUND OF ALL THINGS

LOGIC, ABSTRACTION, AND THE GROUND OF ALL THINGS, 2026

This essay examines the presuppositionalist argument that the existence of logic entails the exis... more This essay examines the presuppositionalist argument that the existence of logic entails the existence of God, advancing five determinate conclusions: the central unargued premise-that only a personal being can ground normative logical structure-is not defended but assumed; conditionalism clarifies the grounding debate but does not resolve it; absolute nothingness is self-undermining as a metaphysical possibility; theological voluntarism destroys the presuppositionalist argument from within; and the most defensible position is a structural realism in the Logos tradition-the view that logical structure is the minimal form of intelligibility and determinacy, prior to the distinction between minds and objects, and constitutive of rational agency as such. The existence of logic supports metaphysical realism about rational structure, but not the conclusion that the specifically Christian God is its necessary ground.

AND THE ORIGIN OF THE GENETIC CODE A Comparative Abductive Assessment

AND THE ORIGIN OF THE GENETIC CODE A Comparative Abductive Assessment, 2026

The origin of life requires not only molecular complexity but instructional information: a system... more The origin of life requires not only molecular complexity but instructional information: a system in which carrier sequences are mapped to functional outcomes through physically instantiated translation machinery. This paper defines instructional information by three criteria: a mapping not fully chemically necessitated by the carrier; convention-dependent translation operative only within a pre-calibrated reading apparatus; and physically distinct interpretive machinery whose own specification is contained within the system it decodes. We compare two hypotheses — unguided physicochemical processes (H₁) and intelligent agency (H₂) — using abductive inference as the formal framework. H₂ is specified minimally as the causal activity of a goal-directed agent capable of selecting among alternative symbolic mappings and implementing a physically instantiated translation system; it is not identified with any particular theological position. We survey three sequential obstacles in prebiotic chemistry and assess the principal naturalistic model classes for code origin, crediting genuine experimental advances while identifying what each leaves unexplained. The argument is comparative: intelligent agency is the only cause independently known to produce systems satisfying all three criteria, while current naturalistic models address partial aspects without demonstrating their joint emergence. Proposed counterexamples are shown to be within-system phenomena. Falsifiability criteria are specified, and the designer-regress objection is addressed. We conclude that, on present evidence, intelligent agency provides a stronger abductive explanation for the origin of biological instructional information than unguided chemistry alone, while holding this assessment explicitly open to revision.

The Information Problem in Macroevolution

The Information Problem in Macroevolution, 2026

The claim that natural selection acting on random genetic variation is the unifying, well-substan... more The claim that natural selection acting on random genetic variation is the unifying, well-substantiated explanation for biological complexity rests on a category error: it conflates the optimization of pre-existing systems, which is well-evidenced, with the origination of novel hierarchically integrated systems, which is not. This paper argues that the gene-centric framework of the Modern Synthesis is structurally inadequate to the explanatory task assigned to it, for three independent reasons. First, biological information is not localized in the genome; it is distributed across at least six non-redundant layers-genomic, regulatory, epigenetic, splicing, extracellular-positional, and maternal-cytoplasmic-only the first of which the Synthesis was designed to address. Second, the origination of integrated developmental architecture requires the coordinated establishment of multiple co-dependent components whose intermediates lie in fitness valleys, rendering them inaccessible to the standard adaptive walk; we develop the populationgenetic mathematics showing that the binding constraint is not the supply of genetic parts-which neutral drift can furnish cheaply-but their coordinated integration into function, and that the waiting time for coordinated change through an unselected intermediate exceeds available time in the small, slowreproducing populations where that constraint bites hardest. Third, the fossil record documents not gradual divergence but the abrupt, fully-equipped appearance of disparate body plans-a pattern that recurs at every major transition and that leading evolutionary theorists (Koonin, Müller, Noble, Shapiro) now explicitly acknowledge the Synthesis cannot explain-though each proposes a naturalistic, not a design-based, remedy. These convergent lines do not constitute a gap argument. They identify a positive signature-specified, hierarchically integrated, multiplexed information-whose only presently observed sufficient cause is intelligent agency. The paper presses this as an explicitly abductive and defeasible inference to the best explanation-not a demonstrative proof-and states the conditions under which it would fail. The deep-time framework is granted throughout, arguendo; the argument is that the mechanism falls short even on the timescale most favourable to it.

The Nachash of Eden Was No Ordinary Snake

The Nachash of Eden Was No Ordinary Snake, 2026

That single three-letter root — נ-ח-שׁ — carries at least three distinct meanings simultaneously: a crawling creature, the act of divination, and bronze-like shining brilliance. The creature that speaks to Eve reasons, predicts, and possesses theological knowledge no animal should have. It behaves less like a reptile and more like a being of oracular intelligence.
In my new article, I trace what two thousand years of scholars, scribes, mystics, and translators made of this word — from the Septuagint's fateful narrowing, to the Gnostics who made the serpent the hero, to Maimonides' purely allegorical reading, to the bronze serpent Moses raised in the desert that Jesus himself invoked.

THE TWO GREAT LEAPS From the First Multicellular Cell to Homo sapiens A Design Perspective on the Staircase of Complexity

THE TWO GREAT LEAPS From the First Multicellular Cell to Homo sapiens A Design Perspective on the Staircase of Complexity, 2026

The history of life contains a small number of transitions so discontinuous in complexity that th... more The history of life contains a small number of transitions so discontinuous in complexity that they stand apart from ordinary evolutionary change. Biologists generally recognize four candidates for this rank: the origin of life from chemistry; the origin of the eukaryotic cell from prokaryotic precursors; the origin of complex multicellularity; and the emergence of a large-brained, language-using, technologically capable primate. This essay focuses on the last two-here called the First Leap and the Second Leap-for a specific reason: they are the transitions for which the fossil record provides firm anchor points, population-genetic timescales can be estimated, and the molecular systems involved are characterized in sufficient detail to make the complexity argument precise. The origin of life and the prokaryote-to-eukaryote transition are equally formidable problems and are treated at length in the companion volume^12; they are bracketed here not because they are less challenging, but because the two leaps examined-from the first demonstrably multicellular eukaryote, Bangiomorpha pubescens, to Homo sapiens-already constitute, on their own, an argument whose evidentiary demands have not been met by the mechanisms currently on offer. One point of method should be stated at the outset. This essay grants the conventional deep-time framework-the radiometric and geochronological dates, the ~1.05-billion-year age of Bangiomorpha, and the billion-year budget that follows-entirely for the sake of argument (arguendo). The aim is to show that the mechanisms run short even on the timescale most favorable to them. This is a deliberate strategy, not an endorsement: where the companion volume^12 contests that timescale on independent grounds, the disagreement is real, and granting deep time here should be read as conceding the opponent's most generous assumptions rather than as a settled commitment.

12 Shroud of Turin image Requirements ( a revision from previous 25 )

14 Shroud of Turin image Requirements ( a revision from previous 25 ), 2026

Earlier enumerations — including the author’s previous “25 requirements” list and comparable lists by Rucker, Fanti, and the STURP team — are valuable but share a methodological weakness: several listed “requirements” are not logically independent. Some describe a single underlying phenomenon in more than one way, which inflates the count and makes “meets all 25” sound stronger than it is. This revised edition reorganizes the constraints into genuinely independent families, demotes derived properties to sub-features of their parent, and adds well-attested characteristics the earlier list under-weighted. The result is a leaner, more defensible set of roughly a dozen independent constraints — harder to attack, and therefore more useful — against which candidate mechanisms are then evaluated. This paper is the direct successor to the author’s earlier 25-constraint framework and paper (Grasso 2025), consolidating and superseding that flat enumeration while preserving all of its underlying evidence.

The Pot and the Potter On Human Moral Judgment of God

The Pot and the Potter On Human Moral Judgment of God, 2026

Critics point to divinely commanded warfare, the deaths of children, and the regulation of slavery, and conclude that the biblical God falls beneath the ethical standards of enlightened humanity. The implicit claim is striking: the creature has appointed itself judge over the Creator.
This essay does not attempt to make that difficulty disappear. There is genuine moral difficulty in these texts, and a Christian should not pretend otherwise. Anyone who reads of the killing of children and feels nothing has not understood what he is reading. The aim here is different — to show four things: first, that the critic’s posture of final moral judgment over God rests on shakier ground than it appears; second, that God does not merely demand submission but actually argues His own case, submitting His justice to scrutiny; third, that the God of the Old Testament and the God of the New are not two characters but one — the one triune God, fully revealed in Jesus Christ; and fourth, that the deepest answer to the problem is not an argument at all, but the cross.

Infinity and the Eternal Past Mapping the Philosophical Debate on Temporal Infinity Temporal succession, completed infinitude, and the limits of what philosophy can establish

Infinity and the Eternal Past Mapping the Philosophical Debate on Temporal Infinity Temporal succession, completed infinitude, and the limits of what philosophy can establish, 2026

It proceeds in three movements. First, it distinguishes infinity from merely large finite quantities and surveys the structural laws of infinite arithmetic that make the question non-trivial. Second, it examines the two principal arguments against a beginningless past: the argument that actual infinites cannot exist in concrete temporal reality (illustrated by Hilbert's Hotel), and the argument that a series formed by

The left panel (green) documents what the scientific and forensic evidence actually shows: the Shroud is the most studied relic on earth, its image formation remains unexplained by any known medieval technique, its wounds match the Gospel accounts of the Passion with forensic precision, and it has proven a powerful tool for evangelism among skeptics. The right panel (amber) documents what the institutional church does in response: the Shroud is largely absent from pulpits worldwide, frequently dismissed alongside fringe claims, viewed with Protestant unease as a Catholic relic, and unknown to the vast majority of believers. At the center, the negative photographic image of the full burial cloth-front and dorsal views of the crucified figure-as revealed by Secondo Pia's landmark 1898 photographs. The caption below the image states the essay's governing paradox: the stronger the evidence becomes, the louder the silence from those best positioned to proclaim it.

THE PHOSPHORUS PROBLEM Geochemical Scarcity, Biochemical Necessity, and the Fine-Tuning Required for the Origin of Life on the Primitive Earth

THE PHOSPHORUS PROBLEM Geochemical Scarcity, Biochemical Necessity, and the Fine-Tuning Required for the Origin of Life on the Primitive Earth, 2026

It forms the backbone of DNA and RNA, constitutes the high-energy currency of metabolism in adenosine triphosphate (ATP), and is essential to membrane lipids and enzyme cofactors. Yet on the primitive Earth, bioavailable phosphorus was vanishingly scarce. The dominant crustal mineral, apatite, is nearly insoluble under most geochemical conditions. Aqueous environments capable of dissolving phosphate were transient or geographically restricted. Competing ionsparticularly calcium, iron, and magnesium-precipitate phosphate out of solution before it can participate in prebiotic chemistry. This paper surveys the geochemical and biochemical dimensions of the phosphorus problem, examines proposed resolutions, and evaluates the degree to which a habitable planet capable of supporting abiogenesis would require precise fine-tuning of planetary parameters-including crustal composition, volatile delivery, impact flux, redox chemistry, and hydrological cycling-to make sufficient phosphorus available at the right time, place, and concentration for the assembly of the first self-replicating molecules.

After the Grounding Argument: Limitations, Honest Alternatives, and the Case for Rational Axiomatic Theism

This follow-up does three things. First, it honestly confronts the principal weaknesses of that argument: the grounding relation remains analogical rather than fully explained; the Principle of Directional Expression is structurally circular; and the modal collapse problem is managed but not dissolved. Second, it examines all plausible alternatives-physics, brute fact, necessary existence, dissolution of the question, temporal theism, and idealism-with equal rigor, acknowledging what each achieves and where each fails. Third, it arrives at what it takes to be the most defensible honest position: that foundational commitments about ultimate reality function as axioms rather than derivable conclusions, that the choice between axioms is a real and consequential judgment rather than an arbitrary one, and that the theistic axiom-a necessarily concrete rational ground that has always existed-remains comparatively better supported than its competitors, not because it solves the problem but because it provides the most unified terminus for the cluster of questions that remain. The paper ends by naming what cannot be named away: a genuine and possibly permanent cognitive limit at the edge of the timelessness-to-time transition.

It rejects the standard production picture, because a timeless source cannot first wait, then decide, then act; that sequence already presupposes time. The alternative developed here is non-temporal metaphysical dependence: time is the finite expression of directed rational order within a concrete physical world. This is the paper's central insight: the arrow of time has a pre-temporal prototype in the rational structure of the ground, and finite creation is where that prototype acquires a temporal body. The bridge is not a mechanical step but a grounding relation: the universe is the finite realization of the same directedness that exists eternally in God.

Esamina come i papi e le autorità ecclesiastiche che si sono succeduti abbiano riconosciuto, regolamentato, autorizzato o commentato la reliquia nel corso di sette secoli di storia documentata. La rassegna distingue tra autorizzazioni liturgiche (feste, messe, uffici, voci del breviario); concessioni di indulgenze; riconoscimenti canonici; permessi di devozione; e dichiarazioni papali moderne. L'articolo sostiene che la Chiesa cattolica non ha mai emanato una definizione dogmatica vincolante riguardo all'autenticità storica della Sindone. Tuttavia, la documentazione cumulativa dell'azione pontificia rivela un atteggiamento istituzionale costante e insolitamente forte nei confronti della Sindone come oggetto sacro degno di venerazione pubblica. Particolare attenzione è riservata alla decisiva fase liturgica sabauda del XVI secolo, in particolare agli atti di Giulio II del 1506, all'approvazione della Festa, della Messa e dell'Ufficio della Sacra Sindone, e alla successiva formula liturgica Tuam Sindonem veneramur, Domine; tuam recolimus Passionem.

The Historical Position of the Catholic Church on the Authenticity of the Shroud of Turin

The Historical Position of the Catholic Church on the Authenticity of the Shroud of Turin, 2026

This article surveys the documented history of papal and pontifical engagement with the Shroud of... more This article surveys the documented history of papal and pontifical engagement with the Shroud of Turin, or Sindone, from the earliest attested ecclesiastical references through the pontificate of Leo XIV. It examines how successive popes and ecclesiastical authorities have recognized, regulated, authorized, or commented upon the relic across seven centuries of documented history. The survey distinguishes between liturgical authorizations (feasts, Masses, Offices, breviary entries); indulgence grants; canonical recognitions; devotional permissions; and modern papal statements. The article argues that the Catholic Church has never issued a binding dogmatic definition concerning the historical authenticity of the Shroud. Nevertheless, the cumulative record of pontifical action reveals a sustained and unusually strong institutional posture toward the Shroud as a sacred object worthy of public veneration. Particular attention is given to the decisive Savoyard-liturgical phase of the sixteenth century, especially the acts of Julius II in 1506, the approval of the Feast, Mass, and Office of the Holy Shroud, and the later liturgical formula Tuam Sindonem veneramur, Domine; tuam recolimus Passionem.

PRECISION BY DESIGN ATOMIC GEOMETRY IN LIFE'S ESSENTIAL ENZYMES

This article extends the argument inward-to the active sites of enzymes that are indispensable for life. Using peer-reviewed structural data, we show that life's most essential enzymes-polymerases, proteases, kinases, and metalloenzymes-function only because their atoms are arranged in precise three-dimensional geometries measurable in ångströms and degrees. We demonstrate that (1) these geometries are not physically necessary-chemistry alone does not force them; (2) they cannot plausibly arise by chance, and natural selection-even where it operates-cannot explain the origin of the very replication and catalytic machinery on which selection itself depends; and (3) they carry unmistakable hallmarks of specified, functional complexity. The inference to intelligent design emerges not from ignorance, but from recognising what kind of cause is known to produce such coordinated atomic precision. 1. Fine-Tuning Beyond the Cosmos The fine-tuning argument is usually staged against the backdrop of the universe. The gravitational constant, the cosmological constant, the nuclear strong force, the mass ratio of the electron to the proton-these fundamental parameters appear to inhabit extraordinarily narrow ranges that permit stable matter, long-lived stars, carbon chemistry, and habitable planets. Physicists such as Martin Rees and Roger Penrose have quantified just how precisely some of these values must fall for a universe capable of sustaining complex life to exist at all. But fine-tuning does not stop at the cosmic scale. It continues into the cell-and more specifically, into the active sites of the enzymes that sustain every living thing on Earth. At the molecular level, life depends not only on having the right atoms, but on those atoms being placed in exact three-dimensional arrangements. Enzymes are not simply chemical catalysts. They are atomic positioning systems: molecular scaffolds that hold reactive groups at specific distances, angles, and orientations so that the correct chemistry-and only the correct chemistry-takes place.
