This book is formed by various chapters where we will see a variety of topics related to the manner in which ideological and epistemological changes of the 19th, 20th and 21st centuries shaped the Spanish language, literature, and film, among other forms of expression, in both Spain and Latin America, and how these media served to the purpose of spreading some ideas or demands. There are articles on ideological representations of linguistic difference and sameness, linguistic change associated to loan words and the ideas those bring modifying our communicative landscape, and the role of Catholic religion on the construction of our dictionary; analysis of some political discourses, ideologies and social imaginaries; even new visions of old literature (a return to the parody in the Middle Ages to analyze its modernnes), and postmodern narrative; discussions on contemporary Spanish poetry and contemporary Central American literature; a new return to the liberation philosophy by analyzing Ellacuria's work; and several studies about concepts such as capitalism, patriarchy, identity, masculinity, homosexuality, globalization, and the Resistence in several forms of expression.
