Crisis de valores y conciencia de cambio en "Don Quijote de la Mancha" y "El Burlador de Sevilla"

Starting whith the triple dimensionality of the languages (diachrony, diatopy and diastraty)I try to approach in this essay the intervention of literature in the social, especially in times of crisis, given itsintervention in discourses and collective imaginaries. An analysis of"El Burlador de Sevilla" by Tirso de Molina as an example of a text, simple echo of the crisis of its time and its Spain, illustrates my general proposal, and an analysis of "Don Quijote" shows the cosnsciousness of the crisis by Cervantes and hisintervention in it through the ironic distance.
