Let me inform (or remind) you how philosophers standardly think
about action ...
‘What events in the life of a person reveal agency; what are his [sic] deeds and his doings in contrast to mere happenings in his history; what is the mark that distinguishes his actions?’
(Davidson, 1971, p. 43)
Davidson, 1971 p. 43
So what is the mark that distinguishes her actions?
The passage that I’ve quoted doesn’t fully answer the question.
(You need to know about basic actions too.)
But here you can see part of the answer.
Davidson holds that the mark is intention.
That is not to say we do only things that we intend to---after all, alerting the prowler is
something Davidson’s man without intending to do so.
Rather, the idea is this.
If you intend something, to turn the light on perhaps, and this intention is appropriately
related to an event, then that event is an action.
(This doesn’t yet tell us which events are actions.)
Brilliant theory, so simple.
But what’s missing here?
We are focussed entirely on an individual acting alone.
There’s a parallel question about joint action:
**What are our doings in contrast to things we merely happen to do in parallel?**
