Lesson 2.4: The Union Betwixt

Glossary

Key Terms

Causal Determinism: The philosophical proposition that every event is necessitated by prior conditions combined with the laws of nature.

Indeterminism: The view that some events are probabilistic or chance occurrences rather than causally necessitated.

Dilemma of Determinism: The philosophical argument that whether determinism is true (our actions are necessitated) or indeterminism is true (our actions are random chance), free will is ruled out under both alternatives.

Hard Determinism: The view that causal determinism is true, determinism is incompatible with free will, and therefore humans lack free will.

Metaphysical Libertarianism: The view that humans possess genuine free will, which requires that at least some human choices are neither causally determined nor purely random, rendering causal determinism false.

Agent Causation: The theory that agents (selves) can directly initiate new causal chains without being determined by prior physical causes.

Compatibilism (Soft Determinism): The view that free will and determinism are compatible, often defining freedom as the ability to act according to one’s desires, values, and motives without external coercion.

The Swerve (Clinamen): Epicurus's hypothesis of an uncaused, minute random deviation in the motion of atoms to preserve moral responsibility and avoid fatalism.

Theological Determinism (Fatalism): The position that human choices are predestined or necessitated by divine will or divine foreknowledge.

Attentional Autonomy: The capacity of an individual to exert voluntary, sustained control over where their attention is directed.

Situationism: The empirical view from social psychology that situational and environmental variables exert a far greater influence on human behavior than internal character traits, beliefs, or moral commitments.

Choice Blindness: A cognitive phenomenon in which individuals fail to detect discrepancies between their actual choices and an altered outcome, often proceeding to confabulate detailed justifications for the option they did not choose.

Apparent Causal Path: Daniel Wegner’s term for the subjective, illusory feeling that a conscious thought directly caused a bodily action, when both were actually triggered by unconscious brain mechanisms.

Confabulation: The production of fabricated or rationalized explanations for one's own behaviors or choices without conscious awareness that the explanation is false.

Important Figures

Epicurus (341–270 BCE): Ancient Greek philosopher who integrated atomism with "the swerve" to explain human moral agency.

Chrysippus (c. 279–c. 206 BCE): Stoic philosopher who addressed free will and causal necessity in Hellenistic thought.

David Hume (1711–1776): Scottish Enlightenment philosopher and classic compatibilist who argued that freedom is the regular union between internal motives, choices, and actions free from external constraint.

Immanuel Kant (1724–1804): German philosopher who argued that acting merely on unreflective desires is animal servitude; real freedom requires cultivating rationality and moral self-discipline. He dismissed Humean compatibilism as "petty word jugglery and a wretched subterfuge".

William James (1842–1910): American philosopher and psychologist who famously rejected compatibilism as a "quagmire of evasion" that obscures the factual problem of free will.

Mark Balaguer: Contemporary philosopher who critiques compatibilism for redefining terms rather than resolving whether humans have radical, indeterministic freedom.

John Doris: Contemporary philosopher who utilizes situationist social psychology experiments to challenge traditional notions of stable character and agent causation.

Chad Wellmon: Academic author of After the University, who argues higher education institutions historically privilege external goods (career placement, status) over internal goods (critical self-awareness, disciplined study).

Daniel Wegner (1948–2013): Social psychologist and author of The Illusion of Conscious Will, who modeled human intention as a post-hoc conscious narrative rather than the initiating cause of bodily action.

Michael Gazzaniga: Prominent experimental neuroscientist who argues modern brain science undermines traditional 17th-century accounts of conscious free will.

Yuval Noah Harari: Historian who highlighted the "Robo-Rat" experiments to illustrate how manipulated desires challenge compatibilist assumptions about felt freedom.

Key Arguments & Thought Experiments

The Killer Clown Argument: A critique against libertarianism showing that if an action is truly undetermined and disconnected from previous desires and character, it would be experienced as completely unpredictable, bizarre, and alienated from the agent (e.g., suddenly dressing like a clown to commit murder).

The Constant Union Argument: Hume's claim that without a deterministic causal link between an agent’s internal motives and their physical actions, actions would be erratic accidents rather than expressions of the agent's character.

The "Word Jugglery" Objection: The charge raised by Kant, James, and Balaguer that compatibilism solves the free will problem by trivializing it—trading the substantive question ("Could I have done otherwise?") for a linguistic distraction ("Did anyone stop me from doing what I wanted?").

The Robo-Rat Objection: The counterexample demonstrating that an agent can act completely in line with their subjective desires without feeling coerced while being entirely controlled from the outside (via implanted neural electrodes), proving that unhindered desire-satisfaction does not equal genuine freedom.

The Good Samaritan Experiment (Darley & Batson, 1973): A social psychology study showing that seminary students on their way to give a lecture on the Good Samaritan were primarily influenced by whether they were in a rush, rather than their religious or moral character traits, when deciding to help a person in distress.
