The Epistemology of Protest offers a polyphonic theory of protest as a mechanism for political communication, group constitution, and epistemic empowerment. The book analyzes the communicative power of protest to break social silences and disrupt insensitivity and complicity with injustice. Philosopher José Medina also elucidates the power of protest movements to transform social sensibilities and change the political imagination. Medina's theory of protest examines the obligations that citizens and institutions have to give proper uptake to protests and to communicatively engage with protesting publics in all their diversity, without excluding or marginalizing radical voices and perspectives. Throughout the book, Medina gives communicative and epistemic arguments for the value of imagining with protest movements and for taking seriously the radical political imagination exercised in social movements of liberation.

Medina's theory sheds light on the different ways in which protest can be silenced and the different communicative and epistemic injustices that protest movements can face, arguing for forms of epistemic activism that resist silencing and communicative/epistemic injustices while empowering protesting voices. While arguing for democratic obligations to give proper uptake to protest, the book underscores how demanding listening to protesting voices can be under conditions of oppression and epistemic injustice. A central claim of the book is that responsible citizens have an obligation to echo (or express communicative solidarity with) the protests of oppressed groups that have been silenced and epistemically marginalized. Studying social uprisings, the book further argues that citizens have a duty to join protesting publics when grave injustices are in the public eye.
