The core issue is whether human actions can be both caused and free. Hard determinists argue that if every event is caused by prior conditions, then people do not have free will. Libertarians argue that genuine free will requires real alternatives and is incompatible with determinism.
Compatibilists argue that freedom can mean acting from your own desires and reasons, even if those desires have causes.
Key Facts
- Determinism is the view that every event, including every human action, is fully caused by prior events and the laws of nature.
- Free will is often defined as the ability to choose or act in a way that is genuinely up to the agent.
- Hard determinism says determinism is true, free will is false, and moral responsibility must be rethought.
- Libertarian free will says free will is real and determinism is false, so some choices are not fully fixed by prior causes.
- Compatibilism says determinism and free will can both be true if free action means acting according to one's own reasons, values, or desires.
- The consequence argument can be stated as: If determinism is true, our actions follow from the past and laws of nature; we do not control the past or laws; therefore we do not control our actions.
- The compatibilist reply can be stated as: A person acts freely when the action comes from their own internal motives rather than external force or coercion.
- Moral responsibility usually requires that the person understood the action, had some control over it, and was not forced or severely impaired.
Vocabulary
- Determinism
- The view that all events and actions are fixed by earlier causes and the laws of nature.
- Free Will
- The ability of a person to choose or act in a way that is meaningfully their own.
- Compatibilism
- The view that free will and determinism can both be true at the same time.
- Hard Determinism
- The view that determinism is true and that humans do not have free will.
- Libertarianism
- In philosophy of free will, the view that humans have free will and determinism is false.
- Moral Responsibility
- The condition of being rightly praised, blamed, rewarded, or punished for an action.
Common Mistakes to Avoid
- Confusing determinism with fatalism is wrong because determinism says events are caused, while fatalism says outcomes will happen no matter what anyone does.
- Assuming compatibilists deny causation is wrong because compatibilists usually accept causation and redefine freedom as acting from one's own motives without coercion.
- Treating randomness as automatic freedom is wrong because a random action may not be controlled by the person or guided by reasons.
- Using free will to mean only doing whatever you want is incomplete because philosophers also ask whether your wants, values, and choices are under your control.
- Claiming moral responsibility is impossible without considering the argument is too quick because some theories ground responsibility in reasons, character, intentions, or social practices.
Practice Questions
- 1 A student says, 'If my decision was caused by my personality and experiences, then it was not free.' Which position does this statement most closely support: hard determinism, libertarianism, or compatibilism?
- 2 In a case with 3 possible explanations for an action, one explanation says the person was physically forced, one says the person acted from their own values, and one says the action was random. Which explanation best fits compatibilist freedom?
- 3 Write the consequence argument in 3 steps using these ideas: the past, laws of nature, control, and present actions.
- 4 A person steals food because they are threatened with serious harm if they refuse. Explain whether this action seems free, unfree, or partly free from a compatibilist point of view.
