Political science focuses on the theory and practice of government and politics at the local, state, national, and international levels. We are dedicated to developing understandings of institutions, practices, and relations that constitute public life and modes of inquiry that promote citizenship. Political theory is concerned mainly with the foundations of political community and institutions. It focuses on human nature and the moral purposes of political association. To clarify these concepts, political theorists draw on enduring political writings from ancient Greece to the present and on various writings by moral philosophers. Political theory also focuses on empirical research into the way political institutions function in practice. Here political theorists subject beliefs about political life found in important political writings to re-examination in the light of ongoing human behavior. In either case, political theory seeks to ultimately deepen political thinking and to spur citizens to responsible and creative political action. Political science, the systematic study of governance by the application of empirical and generally scientific methods of analysis. As traditionally defined and studied, political science examines the state and its organs and institutions. The contemporary discipline, however, is considerably broader than this, encompassing studies of all the societal, cultural, and psychological factors that mutually influence the operation of government and the body politic.
