Some Ambiguities in the Notion of Power

The notion of power is often said to be central to the analysis of politics. But while that analysis is a very ancient activity, the conceptual clarification of the notion of power has been undertaken only in the past generation. The reason for this discrepancy I leave to the historians of political ideas. In this introduction I merely observe that the clarification has not proceeded as far as is needed, so that we are still not at all sure of what we are talking about when we use the term. Nevertheless there is light ahead, owing especially to some formal definitions that have been offered in recent years by Shapley and Shubik, March, Dahl, Cartwright, and Karlsson. By reason of the formality of these definitions the issues of meaning have been more sharply delineated than was previously possible. Hence we have reached the point, I believe, where we may confront definitions with each other and specify precisely how they differ. In so doing we may be able to resolve some of the ambiguities remaining in the concept of power. In that hope this essay is written.
