In This Essay Chisholm Argues That Free Actions Are Possible

In this essay Chisholm argues that free actions are possible because they are caused not by indefinitely long sequences of preceding events but rather by an agent (or self) . He calls the former kind of causation "event causation" and the latter "agent causation." In his view, when we act freely, we act like God-a prime mover that is itself unmoved, an uncaused cause of events.
