Full Idea
Davidson's criterion for the identity of events is a mistake, because we cannot know the causes and effects of an event until we know what that event comprises.
Gist of Idea
You can't identify events by causes and effects, as the event needs to be known first

A Reaction
How many attempts by analytical philosophers to give necessary and sufficient conditions for things seem to founder in this way. Their predecessor is at the end of 'Theaetetus'; you have to know what the sun is before you can define it.
