Dogmatism, prejudice and bigotry are becoming ever more evident on the contemporary political scene and dissent is one of their main targets. The Politics of Dissent explores the negative impact this shift is having on public life, with radically-oriented governments striving to close down dissenting voices in both their political opponents and the mainstream media. It defends dissent as a critical element in the democratic process which ought to be encouraged instead of allowing ourselves to fall into an state of despair, as is increasingly occurring on the political left in the face of the dramatic rise of right-wing populism. The concept is explored in a wide sense to identify how it works in philosophy, religion, science and the arts as well as in politics.
