This book comprises various chapters which explore a variety of topics related to the manner in which ideological and epistemological changes in 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 the purpose of spreading ideas and demands. There are articles on ideological representations of linguistic differences and sameness; linguistic changes associated with loan words and the ideas they bring in modifying our communicative landscape; the role of the Catholic religion on the construction of our dictionary; analysis of some political discourses, ideologies and social imaginaries; new visions of old literature (a return to the parody in the Middle Ages to analyze its moderness) and postmodern narrative; discussions on contemporary Spanish poetry and Central American literature; a new return to the liberation philosophy by analyzing Ellacuría´s work; and several studies about concepts such as capitalism, patriarchy, identity, masculinity, homosexuality, globalization, and the Resistence in several forms of expression.
