Action, is a concept of interest in
philosophy, it has developed into a sub-field called
philosophy of action. Action is what an
agent can do. For example, throwing a ball is an instance of action; it involves an intention, a goal, and a bodily movement guided by the agent. On the other hand, catching a cold is not considered an action because it is something which happens to a person, not something done by one. Generally an agent doesn't intend to catch a cold or engage in bodily movement to do so (though we might be able to conceive of such a case). Other events are less clearly defined as actions or not. For instance, distractedly drumming ones fingers on the table seems to fall somewhere in the middle.
Deciding to do something might be considered a mental action by some. However, others think it is not an action unless the decision is carried out. Unsuccessfully
trying to do something might also not be considered an action for similar reasons (for e.g. lack of bodily movement). It is contentions whether
Believing,
intending, and
thinking are actions since they are mental events.
