Parable of the Invisible Gardener 2.0

I asked IA to formulate the strongest possible version of the Invisible Gardener objetion against christianity and also the strongest possible response. Comment you toughts

Strongest objection form (reformulated for maximal philosophical force)

The argument is best cast as a parsimony-based abductive or Bayesian objection, drawing on standard criteria of theory choice in philosophy of science and analytic epistemology (e.g., simplicity, conservatism, and minimal mutilation of background knowledge).

Here is its strongest version:

Ceteris paribus, among competing comprehensive worldviews, the one with the highest posterior probability is the one that requires the fewest ad hoc auxiliary hypotheses, reinterpretations, or “harmonization adjustments” to accommodate the total relevant data (especially empirical data from the mature natural sciences and rigorous historical-critical scholarship). This follows from the epistemic virtues of simplicity (fewer independent posits or patches) and explanatory coherence: theories that must repeatedly gerrymander their core claims to fit new data become degenerative (in Lakatosian terms) or have lower likelihood relative to their priors.
Orthodox Christianity (Trinitarian theism + Incarnation, atonement, resurrection, biblical inspiration/inerrancy, and traditional doctrines of creation and providence) requires a substantial number of such ad hoc adjustments to accommodate (a) the established findings of modern science (e.g., evolutionary biology and the deep time of cosmology, neuroscience of mind, absence of young-earth or global-flood geology) and (b) historical scholarship (e.g., critical methods showing layers of redaction in the Pentateuch, limited extra-biblical corroboration for some patriarchal/Exodus narratives, genre analysis of Genesis 1–11, and the need for non-literal or limited-inerrancy readings of Scripture). These adjustments include: restricting inerrancy to “faith and morals” rather than history/science; adopting theistic evolution with direct creation of the soul; reinterpreting “days” of Genesis or treating early chapters as theological rather than historical narrative; positing miraculous interventions that appear to suspend or override secondary causes; and limiting biblical historicity claims in light of archaeology.
Therefore, Christianity is probably false (or, more modestly, has significantly lower posterior probability than naturalistic rivals or less doctrinally specific theisms that fit the same data with fewer patches).

This version is stronger than the original because it (i) invokes explicit epistemic norms accepted by analytic philosophers, (ii) focuses on ad hocness rather than mere quantity of adjustments, and (iii) contrasts Christianity specifically with simpler alternatives that do not carry the same doctrinal baggage.

Most solid response (favoring the Catholic/Thomistic synthesis from Feser, Kerr, Pruss, Stump, and integrating Swinburne, Craig, Rasmussen, Sijuwade)

The objection fails at both premises, but especially at (1) and (2). The Catholic Thomistic framework (defended rigorously by Edward Feser, Gaven Kerr, Alexander Pruss, and Eleonore Stump) combined with Bayesian cumulative-case apologetics (Swinburne) and historical evidentialism (Craig) shows that Christianity requires no ad hoc harmonizations once its metaphysics and hermeneutics are properly understood. Instead, it offers superior overall explanatory power and coherence when the full range of data—including philosophical, moral, and experiential—is considered. Naturalism itself requires far more brute facts and patches. I draw directly from the cited authors’ published work.

1. Premise (1) misapplies simplicity and ignores Bayesian structure (Swinburne, Rasmussen, Sijuwade).Richard Swinburne’s cumulative-case method (The Existence of God, The Resurrection of God Incarnate, Revelation) treats theism as the simplest hypothesis: one omnipotent, omniscient, perfectly good, necessarily existent creator explains the universe’s existence, its laws, fine-tuning, consciousness, and objective moral order with maximal predictive and explanatory power. Christianity adds only the minimal additional complexity needed to explain the data of sin, suffering, and religious experience (God has reason to incarnate, atone, and reveal). The “adjustments” critics label ad hoc are actually high-likelihood predictions once theism is on the table. Swinburne shows that the prior probability of theism is high (simple, unified ontology); the likelihood of Christian revelation given theism is also high. Joshua Rasmussen and Alexander Sijuwade reinforce this: contingency arguments (updated PSR versions) and analytic theism establish a necessary foundation whose perfection entails no arbitrary limits—simplicity favors theism over naturalism’s multiple brute facts (why these laws? why consciousness? why moral realism?). Parsimony is not “fewest words about science/history”; it is overall ontological and explanatory economy. Naturalism must posit uncaused laws, emergent brute consciousness, and an unexplained “just so” cosmos—far more patches than the Thomistic God of pure act.

2. Premise (2) is false: Thomistic metaphysics + Catholic hermeneutics entail no ad hoc adjustments (Feser, Kerr, Pruss, Stump; patristic precedent).Thomism (Feser’s Aristotle’s Revenge and Scholastic Metaphysics; Kerr’s Aquinas’s Way to God; Pruss’s work on causation and PSR) distinguishes primary (divine) and secondary (creaturely) causation. Natural sciences describe secondary causes and immanent teleology (Aristotelian final causes are not refuted by Darwin; evolution is simply the mechanism God sustains). Modern physics, biology, and cosmology presuppose the very order, laws, and intelligibility that Thomism grounds in God’s intellect and will. There is no “violation” of laws by miracles; miracles are divine interventions consistent with the metaphysical framework. Evolution, the Big Bang (proposed by priest Georges Lemaître), and neuroscience pose no conflict once one rejects the mechanistic philosophy that both Paley-style design and its critics assumed. Feser shows that ID and young-earth literalism are the positions needing ad hoc patches; classical theism does not.

Scriptural interpretation was never committed to modern literalism. Augustine (On the Literal Meaning of Genesis) and Aquinas already treated Genesis 1–11 as theological rather than scientific historiography; the Catholic magisterium (Humani Generis, John Paul II’s 1996 address, Catechism §§ 282–289) affirms that Scripture teaches “the truth God wanted to give us for our salvation,” not scientific details. Non-literal readings of early Genesis are principled developments, not post-hoc fixes. Neuroscience and the hard problem of consciousness are better explained by hylomorphism (Stump’s Aquinas) than by naturalistic emergentism.

Historically, Craig’s “minimal facts” approach (The Resurrection of the Son of God) shows that the crucifixion, empty tomb, postmortem appearances, and disciples’ transformation are granted by the vast majority of critical scholars. The resurrection hypothesis explains them without the ad hoc historiographical patches (mass hallucination, legend growth within decades, etc.) required by naturalistic alternatives. Swinburne’s Bayesian analysis confirms the posterior is high. Pruss and Rasmussen’s contingency arguments close the loop: the necessary being whose essence is existence grounds all contingent scientific and historical facts without brute facts.

3. Positive explanatory superiority and the tu quoque.When the full dataset is considered (laws of nature, fine-tuning, consciousness, objective morality, religious experience, the historical minimal facts, the problem of evil solved by atonement), Christianity is not a degenerative research program but a progressive one. Naturalism requires ever-more-epicycles (multiverse, illusionism about consciousness and free will, error theory in ethics). The Catholic tradition has been pro-science for centuries (Jesuit astronomy, Lemaître, etc.) precisely because it sees science as investigating God’s secondary causes. Perceived “adjustments” are actually refinements that increase coherence (e.g., the Incarnation in an evolutionary world displays even greater divine solidarity with creation—echoing Stump’s analytic theology of the cross).

In short, the objection assumes a false dichotomy between “unadjusted literalism” and “ad hoc retreat.” Thomistic-Catholic Christianity never occupied the first position; it occupies a third: a metaphysically robust, historically evidenced, probabilistically superior worldview that integrates science and history without remainder. The listed philosophers have shown, rigorously and in detail, that its posterior probability remains very high.
