## Compatibilism as One of Three Positions The free will debate is traditionally structured around three main positions, with compatibilism being one of them. A breakdown of the primary groups. --- 1. Compatibilism (or Soft Determinism) Core Thesis: Determinism is true (every event is causally necessitated by prior events), and this is compatible with free will. Free will is not about being uncaused, but about acting according to one's own desires, reasons, and character without external constraints. Prominent Examples: · [[David Hume]]: Free will is "the power of acting or not acting, according to the determinations of the will." An action is free if it is caused by one's own will and is not coericed. · [[Thomas Hobbes]]: "Liberty is the absence of external impediments." A free agent is one who is not prevented from doing what they desire to do. · Daniel Dennett: A leading contemporary defender. He argues that the kind of free will worth wanting—the kind that grounds moral responsibility—is entirely compatible with determinism. It involves being responsive to reasons, having the capacity for self-control, and being a product of a meaningful history of decision-making. · Harry Frankfurt: Famous for his "hierarchical model" and thought experiments (Frankfurt cases). Freedom requires that your first-order desires (to do X) are aligned with your second-order volitions (the desire to want to do X). This model tries to capture "free will" even in a deterministic world. · Strawson, Ayer, and many contemporary philosophers in the analytic tradition. --- 2. Incompatibilism Core Thesis: Determinism and free will are logically incompatible. You cannot have both. If determinism is true, free will is impossible. Incompatibilism branches into two opposite conclusions: A. Hard Determinism Core Thesis: Determinism is true, and therefore free will does not exist. Moral responsibility, in the traditional "desert-based" sense (deserving praise/blame for being the ultimate originator of an act), is an illusion. · Prominent Examples: · Baruch Spinoza: Viewed human beings as part of nature, subject to its deterministic laws. The feeling of freedom is an illusion born of ignorance of causes. · Paul-Henri Thiry (Baron d'Holbach): An Enlightenment materialist who argued that humans are complex machines wholly governed by physical laws. · Clarence Darrow: The defense lawyer who used deterministic arguments to argue his clients were not ultimately responsible for their crimes. · Modern proponents: Galen Strawson (with his "Basic Argument" that ultimate responsibility is impossible), Sam Harris (neuroscientist/philosopher who argues free will is an illusion both scientifically and introspectively), and many scientists in fields like neuroscience. B. Libertarianism (Metaphysical, not political) Core Thesis: Free will exists (and is required for moral responsibility), therefore determinism must be false. There is some form of indeterminacy or agent-causal power that breaks the deterministic chain of cause and effect. · Sub-types and Prominent Examples: · Agent-Causation: The agent, as a substance, is a distinct kind of cause that can initiate new causal chains. Events are caused by things (agents), not just prior events. · Thomas Reid (historical), Roderick Chisholm (contemporary). · Non-Causal Libertarianism: Free actions are not caused at all—neither deterministically nor by prior mental states. They are simply rational exercises of a power. · G.E.M. Anscombe (influential), some interpretations of Kant's noumenal self. · Event-Causal Libertarianism: Incorporates indeterminism (e.g., from quantum mechanics) into the decision-making process, arguing that decisions are not fully [[Determined - By Robert Sapolsky|determined]] but are not random because they are made for reasons. · Robert Kane: The most prominent modern defender. He argues for "self-forming actions" where effort of will in moral conflict creates an indeterminate break, making the agent the ultimate originator. --- 3. Other Significant Groups / Positions A. Illusionism Core Thesis: Free will (as commonly understood—implying ultimate authorship) is an illusion, but it may be a useful or necessary illusion for society and our sense of self. This is often a pragmatic cousin of hard determinism. · Example: · [[Friedrich Nietzsche]]: Called free will a "theologian's artifice" but saw the concept as deeply embedded in our language and moral practices. B. Pessimism (Impossibilism) Core Thesis: Free will, under any coherent definition (whether compatibilist or libertarian), is impossible. This is a more radical claim than hard determinism. · Example: · Galen Strawson's "Basic Argument": You are ultimately responsible for what you do only if you are responsible for how you are (your character, desires). But you cannot be causa sui (cause of yourself). Therefore, ultimate responsibility is impossible. C. Skepticism / No-Further-Problem Views Core Thesis: The traditional problem is a linguistic or conceptual confusion. Once we clarify our concepts (of freedom, causation, responsibility), the conflict dissolves. · Examples: · P.F. Strawson ("Freedom and Resentment"): Argued that our practices of moral responsibility are grounded in reactive attitudes (resentment, gratitude) that are part of our natural human framework. We cannot and need not justify them by reference to metaphysics. · [[Ludwig Wittgenstein]] and some ordinary language philosophers would see the problem as arising from misusing language. D. Revisionism Core Thesis: Our folk concept of free will is flawed or incoherent. We should revise it to align with science (determinism or naturalism) while preserving what's important about responsibility. · Example: · Manuel Vargas: Argues we should engineer a concept of "free will" that serves our moral and legal practices without requiring metaphysically dubious libertarian foundations. --- #### Summary Table | Group | Core Belief on Determinism & Free Will | Key Inference | Prominent Examples | |--------------------|------------------------------------------|---------------------------------------------------|--------------------------------------------------------| | Compatibilism | Compatible | Determinism can be true and we still have free will | Hume; Dennett; Frankfurt | | Incompatibilism | Incompatible | Determinism and free will cannot both be true | — | | → Hard Determinism | Incompatible | Determinism is true; therefore no free will | Spinoza; d'Holbach; Sam Harris | | → Libertarianism | Incompatible | We have free will; therefore determinism is false | Kane; Chisholm (Agent-Causation) | | Illusionism | — | Free will is a useful illusion | Nietzsche (influential) | | Pessimism | — | Free will is impossible under any definition | Galen Strawson | This landscape shows the debate is not just binary (compatibilist vs. incompatibilist) but includes nuanced positions about the nature, value, and even the coherence of the concept itself. --- #### let's imagine you're playing a giant, super-advanced video game. --- First, what are we talking about? The big question is: Do we really choose what we do, or is everything already set up like a movie playing out? Two ideas get mixed up: 1. "Cause-and-Effect" Set Path (Causal Determinism) · Think of a line of dominoes. You knock over the first one, and click-click-click—every domino after that has to fall in a certain way because of physics. Some people think the universe is like that: what you did yesterday causes what you do today, which causes tomorrow. One path. 2. "Math True Forever" Set Path (Logical/Mathematical Determinism) · Think about math: 2 + 2 will always equal 4. It’s always true, in the past, now, and future. Some people say: "If it’s TRUE right now that you’ll choose chocolate ice cream tomorrow, then it’s already fixed like a math fact—you can’t change it." --- What do the different teams think? Team 1: The "It’s All Set" Team (Hard Determinists) · They say: "The domino chain is real, and that means your future is as unchangeable as 2+2=4. You only feel free." · They mix the two ideas: cause-and-effect makes your future a math-truth. Team 2: The "We Choose Anyway" Team (Compatibilists) · They say: "Hold on! Just because dominoes fall (cause-and-effect) doesn’t mean it’s like math truth. You’re part of the domino chain! Your thoughts, wants, and decisions are the dominoes falling. That’s what freedom is—making choices through your own brain dominoes, not by magic." · They separate the ideas strongly: Cause-and-effect = normal. Math-truth = different thing. Don’t get them confused! Team 3: The "Magic Choice" Team (Libertarians) · They say: "Real choice means the domino chain has to break sometimes. We can start a new chain out of nowhere—like a special power. If everything was fixed like a math truth, we’d be robots." · They mix the ideas to show the problem: If cause-and-effect is total, then we’re trapped in math-like fate. So cause-and-effect must be incomplete! Team 4: The "Doesn’t Matter" Team (Skeptics/P.F. Strawson fans) · They say: "Guys, we’re overthinking this. Whether dominoes or math truths, we still get mad when someone trips us, and say 'good job!' when someone shares. That’s what matters—not the physics." --- Simple Picture Imagine a choose-your-own-adventure book. · Cause-and-Effect Set Path = The book is already written. When you pick page 10, page 20 happens next because the author linked them. · Math Truth Set Path = Someone already read the whole book and says: "It is TRUE you will end on page 50." That truth is fixed like 2+2=4. The fight is about: · "It's all written" vs. "But I'm the one choosing the pages as I go!" vs. "The book should have real multiple endings, not just one!" --- The bottom line: Some people think cause-and-effect = math-like fate (so no freedom). Others say cause-and-effect is just how choices work, not fate (so freedom is fine). It all depends on whether you blend the two ideas or keep them apart. `Concepts:` `Knowledge Base:`
