Most of us intuitively assume that ourselves and others have the freedom to make conscious choices about how we behave, and that this freedom constitutes 'free will'. On the basis of this freedom, we further assume that people can be held responsible for their actions (if people are not free to make their own choices, how can they be held accountable?). These assumptions underpin law, religion, politics, feelings of guilt and accomplishment, and our interactions with each other. But many scientists and philosophers argue that free will, as commonly conceived, is an illusion, and does not exist.
Summary: Free Will outlines the three main approaches to the question of whether or not we have free will - hard determinism, compatibilism, and libertarianism - and for each approach considers the merits, and the implications for notions of personal responsibility.
