The centuries-dominant philosophical traditions of determinism and freedom, Compatibilism and Incompatibilism, are examined. According to the first, determinism is consistent with our freedom and moral responsibility; according to the second, it is inconsistent with them. Honderich considers Compatibilism's argument that our freedom consists in voluntariness, doing what we desire and not being coerced; hence its conclusion that determinism and freedom can go together. He also examines Incompatibilism's argument that our freedom consists in origination or free will, our choosing without our choosing's being caused; hence the conclusion that determinism and freedom are inconsistent.
