Radical democracy is a type of democracy that advocates the radical extension of equality and liberty. Radical democracy is concerned with a radical extension of equality and freedom, following the idea that democracy is an unfinished, inclusive, continuous and reflexive process.
Within radical democracy there are three distinct strands, as articulated by Lincoln Dahlberg. These strands can be labeled as agonistic, deliberative and autonomist.
The first and most noted strand of radical democracy is the agonistic perspective, which is associated with the work of Laclau and Mouffe. Radical democracy was articulated by Ernesto Laclau and Chantal Mouffe in their book Hegemony and Socialist Strategy: Towards a Radical Democratic Politics, written in 1985. They argue that social movements which attempt to create social and political change need a strategy which challenges neoliberal and neoconservative concepts of democracy. This strategy is to expand the liberal definition of democracy, based on freedom and equality, to include difference.
According to Laclau and Mouffe "Radical democracy" means "the root of democracy". Laclau and Mouffe claim that liberal democracy and deliberative democracy, in their attempts to build consensus, oppress differing opinions, races, classes, genders, and worldviews. In the world, in a country, and in a social movement there are many (a plurality of) differences which resist consensus. Radical democracy is not only accepting of difference, dissent and antagonisms, but is dependent on it. Laclau and Mouffe argue based on the assumption that there are oppressive power relations that exist in society and that those oppressive relations should be made visible, re-negotiated and altered. By building democracy around difference and dissent, oppressive power relations existing in societies are able to come to the forefront so that they can be challenged.
The second strand, deliberative, is mostly associated with the work of Jürgen Habermas. This strand of radical democracy is opposed to the agonistic perspective of Laclau and Mouffe.
