Abstract
The concept of power has long played a significant role in political thought, and recent decades have witnessed many attempts to analyze power and provide criteria for its measurement. In spite of this impressive literature, however, our understanding of power remains inadequate. Specifically, no fully comprehensive conceptual framework exists within
which questions about power can be formulated precisely and dealt with systematically. In the absence of such a framework it is difficult to investigate empirical questions, such as the extent to which a country is dominated by a 'power elite,' and it is hard to discuss normative issues, such as the relationship between power and freedom, or the relationship between equality of power and justice. In this paper I shall outline a theory of power the ultimate aim of which is to shed light on empirical and normative questions in the political domain.
