Power toandpower over: two distinct concepts of power?

In this article, I analyze the relations between the concepts of power to and power over. The distinction between these two interpretations of power is commonly based on the assumed relational nature of attributions of power over as opposed to the dispositional nature of attributions of power to. I argue, by contrast, that power to refers to social relations as well, and I suggest, accordingly, to consider power to and power over as describing the same category of social facts. As a consequence, they should not be thought of as two distinct concepts of power, but as representing two analytically distinguishable aspects of a single and unified concept of social power.
