Power is one of those words that is easy to understand but hard to define in a precise manner. We know it means "clout" or "juice" or "muscle" or "the ability to make things happen." We know it comes from words implying the ability to act in a strong, compelling, and direct way, but we also know that power can be projected in a very quiet and indirect manner.

By "power" I mean "the capacity of some persons to produce intended and foreseen effects on others" (Wrong, 1995). This is a very general definition that allows for the many forms of power that can be changed from one to another, such as economic power, political power, military power, ideological power, and intellectual power (i.e., knowledge, expertise). It leaves open the question of whether "force" or "coercion" is always lurking somewhere in the background in the exercise of power, as many definitions imply.
