Scanlon contractualism evolutionary debunking arguments normative objectivity Sharon Street

### Analytic Metaethics and Evolutionary Naturalism In contemporary analytic philosophy, philosophical naturalism—the view that reality contains only the entities and causal mechanisms recognized by the natural sciences—poses a foundational challenge to normative objectivity. The debate centers on **Evolutionary Debunking Arguments (EDAs)**: if human evaluative judgments were shaped by natural selection solely to promote reproductive fitness, can moral claims retain stance-independent truth? ### Key Figures and Primary Texts The debate was crystallized by **Sharon Street** in *“A Darwinian Dilemma for Realist Theories of Value”* (2006). Street presents normative realists with a fork: 1. **Deny a link** between evolutionary pressures and objective normative truths, which makes any alignment between them an improbable “matter of sheer luck,” collapsing into radical moral skepticism. 2. **Assert a link** (e.g., that tracking objective moral truth was fitness-enhancing), which Street rejects as scientifically unparsimonious compared to the naturalistic hypothesis that such tendencies merely facilitated survival and genetic transmission. Street concludes that objectivity cannot be mind-independent; instead, she defends metaethical constructivism, where normative facts are constituted from within an agent’s practical standpoint. In contrast, **T. M. Scanlon** defends both contractualism—defining moral wrongness as acts disallowed by principles that no one could reasonably reject (*What We Owe to Each Other*, 1998)—and **Reasons Fundamentalism** (*Being Realistic about Reasons*, 2014). Scanlon advances a non-naturalist cognitivism: normative claims express irreducibly normative truths about reasons that do not require causal interaction with physical entities, drawing a direct parallel to mathematical truths. ### Concepts and Internal Tensions * **Reflective Equilibrium:** Scanlon argues that normative knowledge is secured through rational deliberation and systematic coherence. While our initial, unreflective starting points may be biologically conditioned, reflective equilibrium allows reasoners to scrutinize, revise, and discard evolutionary biases. * **The "Garbage In, Garbage Out" Counter:** Debunkers like Street respond that reflective equilibrium cannot vindicate realism. If evolutionary forces “thoroughly saturated” our initial evaluative tendencies, coherently organizing those starting points merely systematizes Darwinian contaminants rather than tracking stance-independent truth. ### Scientific and Epistemic Status Mainstream evolutionary biology confirms that human sociality, kin altruism, and reciprocal cooperation evolved via natural selection. However, whether this genealogy epistemically undermines normative objectivity remains an open philosophical debate, dividing the discipline into metaethical naturalists, non-naturalist realists, and constructivists.

evolutionary psychology altruism to strangers evolutionary mismatch maladaptation kin selection peer reviewed

### Position & Internal Schisms In evolutionary biology, anthropology, and the behavioral sciences, altruism toward genetically unrelated strangers presents an evolutionary puzzle. Classical evolutionary theory posits that self-sacrificing behaviors evolve via **kin selection** (W. D. Hamilton’s inclusive fitness theory, where altruism spreads if $rB > C$) or **reciprocal altruism** (Robert Trivers, direct/indirect reciprocity where assistance is repaid). Because costly aid to anonymous strangers in one-shot interactions yields neither genetic return nor future reciprocity, researchers disagree on whether such behavior is an evolutionary accident or an evolved adaptation. Two prominent theoretical branches explain this divergence: 1. **The Evolutionary Mismatch (Maladaptation) Hypothesis**: Classical evolutionary psychologists (such as Leda Cosmides and John Tooby) argue that contemporary altruism toward strangers is an evolutionary byproduct or "misfire." Because ancestral hominins evolved in small, Pleistocene foraging bands where individuals were closely related or engaged in repeated interactions, natural selection forged psychological heuristics geared for reciprocity and reputation. In modern mass societies, these mechanisms operate in an evolutionarily novel environment, producing altruism that is biologically maladaptive. 2. **Gene-Culture Coevolution and Cultural Group Selection**: Anthropologists and behavioral economists—notably Robert Boyd, Peter Richerson, Samuel Bowles, and Joseph Henrich—contest the mismatch model. In landmark cross-cultural studies (e.g., Henrich et al., *Foundations of Human Sociality*, 2004) and theoretical papers such as Fehr and Henrich’s *"Is Strong Reciprocity a Maladaptation?"* (2003), they demonstrate that humans exhibit **strong reciprocity**: a predisposition to cooperate and punish norm violators in one-shot anonymous interactions. They argue that intergroup competition favored cultural norms and group-beneficial social institutions, which in turn selected for genuinely prosocial human psychologies. ### Epistemic Status & Consensus Mainstream biology broadly agrees on kin selection and direct reciprocity as foundational pillars of animal sociality. However, the ultimate driver of human large-scale cooperation remains a contested, active frontier: while standard evolutionary psychology treats one-shot stranger altruism as a cognitive spillover from ancestral living, cultural evolutionists regard it as a distinct, co-evolved adaptive architecture central to human ultrasociality.

Christian theological response evolutionary debunking morality agape natural law Thomas Aquinas

### The Christian Response to Evolutionary Debunking Arguments Evolutionary debunking arguments (EDAs) posit that because human evaluative faculties evolved to promote reproductive fitness rather than track objective reality, moral realism is epistemically defeated. Mainstream Christian theology (Catholic, Orthodox, and Protestant) rejects this conclusion. While accepting the scientific consensus that cooperative instincts and social behavior have evolutionary roots, theologians distinguish this biological fact from the unproven philosophical claim that natural origins undermine moral objectivity. Instead, Christianity views biological processes as secondary causes (*causae secundae*) through which divine providence operates. ### Aquinas, Natural Law, and Practical Reason In the Catholic tradition, Thomas Aquinas provides the classical framework reconciling biological inclinations with moral truth. In the *Summa Theologiae* (I-II, q. 94, a. 2), Aquinas defines natural law as the rational creature’s “participation of the eternal law” (*participatio legis aeternae in rationali creatura*). Rather than viewing basic animal drives as moral illusions, Aquinas argues that biological inclinations—such as self-preservation and the protection of offspring—are baseline natural goods that practical reason discerns, integrates, and directs toward a higher *telos*. Grace does not negate this evolutionary substrate; as Aquinas famously states, “Grace does not destroy nature, but perfects it” (*gratia non tollit naturam, sed perficit*, *ST* I, q. 1, a. 8, ad 2). ### Distinctive Concepts, *Agape*, and Confessional Tensions A central theological rejoinder concerns *agape*—the sacrificial, self-giving love exemplified in Christ and commanded toward strangers and enemies (Matthew 5:44; Romans 5:8). Theologians like Stephen J. Pope (*Human Evolution and Christian Ethics*) point out that while natural selection accounts for kin selection and reciprocal altruism, it cannot fully account for or explain away radical *agape*, which consistently overrides evolutionary self-interest and genetic proliferation. Key internal branches navigate this dynamic with distinct emphases: * **Roman Catholicism:** Leverages Thomistic natural law, holding that human reason can reliably discern real moral obligations embedded in human nature. * **Protestantism:** While modern scholars utilize Alvin Plantinga’s “Evolutionary Argument Against Naturalism” to argue that secular naturalism self-defeats cognitive reliability, historic Reformed thought emphasizes the noetic effects of the Fall, maintaining that sin distorts natural reason and necessitates divine revelation. * **Eastern Orthodoxy:** Interprets creation teleologically through the *logoi* (as formulated by Maximus the Confessor), viewing humanity's evolved nature as an incomplete baseline destined for healing and deification (*theosis*), where biological instincts are transfigured by divine energies.

Buddhist metaethics karuna universal compassion evolutionary biology conventional truth paramartha satya

### Buddhist Metaethics: Compassion, the Two Truths, and Evolutionary Constraints #### 1. Core Position and Philosophical Architecture In Buddhist metaethics, moral obligation is inextricably anchored in ontology. Compassion (*karuṇā*)—the drive to alleviate suffering (*duḥkha*)—is not merely an affective preference but the rational consequence of seeing reality accurately. This rests upon the **Two Truths doctrine** (*satyadvaya*): * **Conventional Truth (*saṃvṛti-satya*)**: The pragmatic, everyday realm of conventional persons, karmic cause-and-effect, and normative duties. * **Ultimate Truth (*paramārtha-satya*)**: The irreducible reality that all phenomena and persons lack intrinsic essence (*svabhāva*) and an enduring, separate self (*anātman*). Mahāyāna ethicists argue that because persons are conceptual fictions rather than ultimate ontological entities, suffering is ultimately "ownerless". Impartial, universal compassion necessarily follows: without an ontologically bounded self, there is no rational ground for prioritizing one stream of suffering over another. #### 2. Canonical Foundations and Primary Texts * **Nāgārjuna (*Mūlamadhyamakakārikā* XXIV.8–10)** establishes that ethical action cannot function without both truths: *"Without relying on everyday convention, the ultimate cannot be expressed; without realizing the ultimate, nirvāṇa cannot be attained"*. * **Śāntideva (*Bodhicaryāvatāra* VIII.90–103)** provides the classical locus for Mahāyāna moral reductionism, arguing for the equalization and exchange of self and other (*parātmasamatā*): *"Suffering has no owner; all of it without distinction is to be prevented simply because it is suffering... just as the hand protects the foot from pain, so must each protect all"*. #### 3. Tensions, Branches, and Dialogue with Evolutionary Biology * **Internal Branches**: Theravāda traditions typically cultivate *karuṇā* as one of the four *brahmavihāras* (sublime states) within an individual path toward *arahantship*, often characterized by contemporary philosophers (e.g., Damien Keown, Charles Goodman) as a virtue ethic or rule-consequentialism. Mahāyāna and Vajrayāna frame *karuṇā* indivisibly from emptiness (*śūnyatā*), requiring the bodhisattva vow to indefinitely postpone private liberation for all beings. * **Evolutionary Biology Divergence**: Mainstream evolutionary biology explains human altruism via kin selection (Hamilton’s rule) and reciprocal altruism (Trivers), which naturally hardwire parochial, preferential in-group favoritism and self-preservation. Contemporary scholars of Buddhist ethics (such as Mark Siderits and John Dunne) demonstrate that Buddhism naturalizes ethical intuition while overturning its biological limitations. Conventional evolutionary mechanisms explain *how* empathy arose biologically, but Buddhist ultimate analysis deconstructs the cognitive illusion of a bounded ego, transmuting partial, genetically biased kin-care into radical, species-blind universal impartiality.

Islamic moral realism fitra evolutionary ethics objectivity of ethical obligations

### Islamic Theology, *Fiṭrah*, and the Objectivity of Ethical Obligations Islamic thought affirms that moral obligations possess transcendent, objective authority, though classical and contemporary thinkers debate whether that objectivity is grounded intrinsically in the nature of actions or extrinsically in divine command. #### Internal Theological Branches: The *Ḥusn* and *Qubḥ* Debate The central meta-ethical dispute in classical *kalām* (scholastic theology) concerns *al-ḥusn wa-l-qubḥ* (the moral goodness and reprehensibility of acts): * **Muʿtazilism and Imāmī Shīʿism** argue for strong **moral realism and ethical rationalism** (*al-ḥusn wa-l-qubḥ al-ʿaqliyyān*). Thinkers like the Muʿtazilite Qāḍī ʿAbd al-Jabbār (d. 1025, *Al-Mughnī*) and Shīʿī theologian al-Sharīf al-Murtaḍā maintain that acts possess intrinsic, stance-independent moral properties discernible through unassisted human intellect (*ʿaql*). Revelation (*sharʿ*) confirms and provides specific legal details for these objective moral realities. * **Ashʿarism** (dominant historically in Sunni thought) espouses **theological voluntarism** (*al-ḥusn wa-l-qubḥ al-sharʿiyyān*). Figures like al-Ghazālī (d. 1111) and Fakhr al-Dīn al-Rāzī (d. 1210) argued that actions carry no mind-independent moral essences; an act is good solely because God commands it and evil because God prohibits it. Moral objectivity is rooted entirely in God’s sovereign decree. * **Māturīdism** adopts a mediating position: the intellect can intuitively grasp the objective rational qualities of good and evil in fundamental virtues (such as gratitude or justice), but binding moral accountability and eternal sanction (*taklīf*) are strictly activated by prophetic revelation. #### Distinctive Concept: *Fiṭrah* and the Epistemic Access to Moral Truth The epistemological bridge between human nature and objective morality is ***fiṭrah***—the primordial, divinely instilled normative orientation. * Scripturally anchored in **Surah Ar-Rūm (30:30)**—*“Adhere to the fiṭrah of Allah upon which He has created mankind”*—and the *ḥadīth* that *“Every child is born upon the fiṭrah”* (Ṣaḥīḥ al-Bukhārī), it implies an innate moral compass that perceives justice and truth. * Traditionalists like **Ibn Taymiyyah** (d. 1328, *Darʾ Taʿāruḍ al-ʿAql wa-l-Naql*) elevated *fiṭrah* as an innate cognitive and ethical capacity uniting reason, conscience, and revelation. * In Sufism, moral life is framed as spiritual purification (*tazkiyat al-nafs*) to restore the clouded *fiṭrah* and actualize the Divine Names within creation. #### Contemporary Engagement with Evolutionary Ethics Contemporary Muslim philosophers and theologians explicitly distinguish the **mainstream empirical consensus** of evolutionary biology (which models proximate mechanisms like kin selection and reciprocal altruism) from **philosophical evolutionary ethics** and anti-realist "debunking arguments" (which reduce moral norms to survival heuristics). Islamic thinkers argue that evolutionary adaptations explain descriptive behavioral tendencies, but cannot bridge David Hume’s is–ought divide or ground normative duty. Objective moral duties (*taklīf*) require an ontological ground—whether God's will or God's purposeful design embedded within the *fiṭrah*. Without this transcendent grounding, human conscience is unmoored from truth.

Mencius ren child falling into well moral origins evolutionary debunking innate goodness

### Moral Origins and Innate Goodness in East Asian Thought In classical Confucianism, Mencius (*Mengzi*, 4th century BCE) posits that human nature (*xing*) possesses innate moral inclinations (*xing shan*). In *Mengzi* 2A6, he illustrates this through the thought experiment of a bystander witnessing an infant about to perish: > “Suppose someone suddenly saw a child about to fall into a well: anyone in such a situation would have a feeling of alarm and compassion—not because one sought to get in good with the child’s parents, not because one wanted fame among one’s neighbors... From this we can see that if one is without the feeling of compassion, one is not human.” Mencius identifies this spontaneous reaction as a moral “sprout” (*duan*). The four sprouts—unreflective compassion, shame, deference, and discernment—are latent affective capacities that, through deliberate reflection (*si*) and ethical practice, mature into the cardinal virtues: benevolence (*ren*), righteousness (*yi*), propriety (*li*), and wisdom (*zhi*). #### Internal Tensions: Xunzi and Daoism This optimistic developmental model sparked foundational debates: - **Xunzi** (3rd century BCE) countered that human nature is inherently unruly (*xing e*); morality is not an innate botanical unfolding, but a difficult artificial straightening (*wei*) achieved through external rites (*li*) and strict teacher authority. - **Daoism** (*Daodejing*, *Zhuangzi*) attacked both Confucian camps, arguing that rigid virtues like *ren* and *yi* reflect a decay of natural balance (*decline of Dao*), warning that codified moral cultivation calcifies and perverts spontaneous, unforced alignment with the cosmos (*ziran*). #### Contemporary Science and Evolutionary Debunking Contemporary comparative philosophers (e.g., Owen Flanagan in *Moral Sprouts and Natural Teleologies*, Bryan Van Norden) connect Mencian sprouts to modern moral psychology. * **Consensus vs. Speculation**: Mainstream empirical work in evolutionary anthropology and developmental psychology confirms that humans possess innate, early-emerging prosocial instincts—such as spontaneous empathy and early cooperation—shared in rudimentary form with other primates. * **Evolutionary Debunking**: Philosophers note that evolutionary debunking arguments (which claim moral instincts were selected strictly for reproductive fitness rather than tracking objective metaphysical truths) challenge Western platonism more than Mencius. For Mencius, *ren* is not an abstract metaphysical deduction, but an embodied, biological endowment that ethical communities must cultivate into mature virtue.

cognitive neuroscience prosocial behavior stranger empathy domain general moral reasoning vs hardwired instincts

In mainstream cognitive neuroscience, cognitive science, and neuropsychiatry, prosocial behavior toward strangers is understood not as the product of a dedicated, hardwired “moral organ,” but as the dynamic convergence of evolutionarily ancient affective circuits with domain-general computational systems. Empirical consensus models this architecture across three interconnected networks: 1. **Affective Resonance:** Witnessing distress recruits the vicarious “pain matrix”—chiefly the anterior insula (AI) and anterior midcingulate cortex (aMCC)—which mirrors sensory and emotional suffering. 2. **Mentalizing / Theory of Mind:** Inferring the beliefs, intentions, and perspectives of unfamiliar agents recruits the temporoparietal junction (TPJ), precuneus, and medial prefrontal cortex (mPFC). 3. **Domain-General Valuation:** Decisions to help rely on the same reward and reinforcement circuitry that computes non-social value (the ventral striatum and ventromedial prefrontal cortex [vmPFC]), providing a “common neural currency” for evaluating costs and altruistic payoffs. A foundational tension within the field concerns the boundary between instinctual empathy and cognitive deliberation. Evolutionary and social neuroscience demonstrate that default affective empathy is intrinsically prone to **parochial altruism**—an ingrained bias favoring kin and in-group members over outgroup strangers. In a landmark fMRI study on intergroup suffering, Hein, Singer, and colleagues (2010) demonstrated that while observing an in-group member’s pain triggered AI activation that directly predicted costly helping, viewing an outgroup stranger’s suffering diminished this response and could instead elicit counter-empathic activation in the nucleus accumbens. Extending moral concern to outgroup strangers typically requires top-down cognitive overrides. In Joshua Greene’s influential **dual-process theory of moral judgment**, fast, emotionally driven intuitions mediated by the amygdala and vmPFC are modulated or overridden by deliberative, domain-general cognitive control hosted in the dorsolateral prefrontal cortex (dlPFC). As developmental and affective neuroscientists Jean Decety and Jason Cowell (2014) conclude, “empathy is not the only moral motivator and does not systematically lead to moral decisions”; raw empathy can exacerbate parochial bias, whereas universal prosociality demands domain-general executive reappraisal and abstract moral principles. While fringe theories occasionally propose fully innate “moral grammar” modules, current empirical consensus views stranger-directed prosociality as an evolutionary kludge: ancient mammalian caregiving and attachment mechanisms expanded and governed by domain-general executive functions.
