Abstract
THE CONCEPT of basic action rests upon a not especially controversial observation and a standard sort of philosophical argument. The observation is that there occur a great many actions in which what is said to be done—say a—is not done directly but rather through the agent doing something b, distinct from a, which causes a to happen. Thus I move a stone by pushing against it, and the pushing, itself an action, causes the locomotion of the stone when all relevant conditions are supposed benign. Sometimes an agent m performs an action in which b is done and another occurrence a is caused by b, but as a is only a consequence of b and is not itself said to be done, such cases fall outside the circumference of the observation just described. What falls within that circumference I designate nonbasic actions, leaving it open that there may be species of nonbasic actions other than those specified by this observation.
