In this conversation with RevDem assistant editor Lorena Drakula, Michael Freeden – leading political theorist and author of the new book Concealed Silences and Inaudible Voices in Political Thinking – discusses the various forms of political silences; the problems of superimposing and inventing voices; the effects of the unnoticeable and the unknowable in political thinking, with the aim of understanding the complex and often hidden aspects of silence that shape our political beliefs and actions.
