The editor of Political Theory asked us to respond to the question, 'What is political theory?' This question is as old as political theory or political philos- ophy. The activity of studying politics, whether it is called science, theory, or philosophy, always brings itself into question. The question does not ask for a single answer, for there are countless ways of studying politics and no univer- sal criteria for adjudicating among them. Rather, the question asks, 'What comparative difference does it (...) make to study politics this way rather than that?' Political theory or philosophy not only spans three millennia of study- ing politics in innumerable ways but also three millennia of dialogues among practitioners over various approaches, their relative merits, and the contest- able criteria for their comparison. Because there is no definitive answer, there is no end to this dialogue. Rather, it is the kind of open-ended dialogue that brings insight through the activity of reciprocal elucidation itself. Dialogue partners gain insight into what ruling, being ruled, and contesting rule is through the exchange of questions and answers over different ways of study-ing politics and different criteria for their assessment in relation to how they throw light on different aspects of the complex worlds of politics-and what counts as the 'different aspects of the complex worlds of politics' is also ques- tioned in the course of the dialogue.'.
