In recent philosophicalliterature we find widespread acceptance of the distinction between things people do and things that happen to them. Some notion of causality is often introduced to explain this contrast between the two kinds of events. Our deeds are said to be the events we ourselves produce; and events to which we make no causal contribution are said to be things that befall uso These two analytical contentions are mutually independent. Why are they important? They seem to provide an economical account of what it is to act and what it is to undergo something.
