Causation is a concept that plays an essential role in reasoning with 
  <I>commonsense.</I> It is a property inherent to the dynamics of
  changing environments. Therefore, it should follow that causation
  should also play an essential role in the theories of action and
  change. However, in this article we postulate that causation is a form
  of <I>abstraction.</I> As a consequence of this view, one should not
  attempt to model causation as a primitive relationship between
  entities. Rather, causation should be viewed as an abstract
  relationship, which can be derived from observations (as a
  correlation) or derived from our knowledge of the structure of the
  world.

In this article, we explore the modeling of two types of problems
  where causation appears to be necessary. We illustrate the problems with some
  simple examples found in the literature. We show that by decreasing
  the level of abstraction one can obtain the right results.
