What the thing is
Free will is a tripartite philosophical construct: the capacity to choose among alternatives, the control required for moral responsibility, and the status of being the ultimate originator of action.
Where it came from
It originated in ancient Greek philosophical literature. The term ‘free will’ (liberum arbitrium) entered usage in 4th-century CE Christian philosophy. Compatibilist accounts appear in Aristotle (4th century BCE) and Epictetus (1st century CE); incompatibilist accounts are attributed by Susanne Bobzien to Alexander of Aphrodisias (3rd century CE).
What it gets right
It correctly ties free will to moral responsibility, praise, and culpability. Actions must be freely chosen for those judgments to apply.
What it gets wrong
It conflates three distinct capacities — alternative choice, control for responsibility, and origination — as one concept. That blurs analytical precision.
Why it matters now
Because debates over automation, AI agency, criminal sentencing, and neuroscientific determinism all rest on unstated assumptions about which of the three capacities — choice, control, or origination — actually grounds responsibility.
Is it worth your time
Yes — if you care about moral responsibility, not metaphysics.
