Politics (from Greek politikos "of, for, or relating to citizens") as a term is generally applied to the art or science of running governmental or state affairs, including behavior within civil governments, but also applies to institutions, fields, and special interest groups such as the corporate, academic, and religious segments of society. It consists of "social relations involving authority or power" and to the methods and tactics used to formulate and apply policy.

Modern political discourse focuses on democracy and the relationship between people and politics. It is thought of as the way we "choose government officials and make decisions about public policy".

The word politics comes from the Greek word Πολιτικά (politika), modeled on Aristotle's "affairs of the city", the name of his book on governing and governments, which was rendered in English mid-15 century as Latinized "Polettiques". Thus it became "politics" in Middle English c. 1520s (see the Concise Oxford Dictionary). The singular politic first attested in English 1430 and comes from Middle French politique, in turn from Latin politicus, which is the latinisation of the Greek πολιτικός (politikos), meaning amongst others "of, for, or relating to citizens", "civil", "civic", "belonging to the state", in turn from πολίτης (polites), "citizen" and that from πόλις (polis), "city".

Slavoj Žižek (pronounced [ˈslavoj ˈʒiʒɛk]; born 21 March 1949) is a Slovenian philosopher and cultural critic working in the traditions of Hegelianism, Marxism and Lacanian psychoanalysis. He has made contributions to political theory, film theory and theoretical psychoanalysis.

He has been a visiting professor at, among others, the University of Chicago, Columbia University, London Consortium, Princeton University, New York University, The New School, the University of Minnesota, the University of California, Irvine and the University of Michigan. He is currently the International Director of the Birkbeck Institute for the Humanities at Birkbeck, University of London and president of the Society for Theoretical Psychoanalysis, Ljubljana.

Žižek uses examples from popular culture to explain the theory of Jacques Lacan and uses Lacanian psychoanalysis, Hegelian philosophy and Marxist economic criticism to interpret and speak extensively on immediately current social phenomena, including the current ongoing global financial crisis. In a 2008 interview with Amy Goodman on the New York City radio show Democracy Now! he described himself as a "communist in a qualified sense" and in another appearance on the show in October 2009 he described himself as a "radical leftist".
