Free Will and Moral Responsibility

The debate over free will is one of the oldest and most important in philosophy. It has profound implications for ethics: if human beings do not have free will — if our actions are determined by prior causes beyond our control — then it seems unfair to hold people morally responsible for what they do. The AQA A-Level specification requires you to understand hard determinism, soft determinism (compatibilism), libertarianism, and the theological perspectives of predestination.

Key Definition: Free will is the capacity of rational agents to choose between different possible courses of action. The debate over free will asks whether this capacity is genuine or merely an illusion.

Hard Determinism

Hard determinism holds that all events, including human actions and decisions, are entirely determined by prior causes operating according to natural laws. Free will is an illusion — we feel as though we choose freely, but in reality, every thought, desire, and action is the inevitable product of preceding causes.
