The paper explores the idea of social change towards democracy from the liberal and conventional perspective presented in the work of Francis Fukuyama and compares it with the proposal of social evolution made by Hauke Brunkhorst, who combines aspects of the Habermasian communicative theory and Marxian dialectical materialism. The objective is to present an idea of social transformation from the disruptive communicative actions carried out in the public sphere by social movements in a conflictive social context through the public expression of the experiences of injustice. © 2021 Ariadna Ediciones.
