Virginia Aspes erudite Approaches to the Theory of Freedom offers a new interpretation of Primero Sueno probably the highest Spanish-written poem, written by the nun Sor Juana Ines de la Cruz . Aspe considers the philosophical and theological influences regarding Sor Juanas development of her concept and ideal of freedom. With vast erudition, Aspe helps advance the field of Sor Juana studies beyond what Paz was able to accomplish. She emphasises the influence of the Jesuit theology of the University of Coimbra. New perspectives and references available to the Spanish speaking world, such as the recent translation of several previously unknown Latin texts from Sor Juanas Mexican contemporaries, provide insights that help Aspe take our understanding of the poem further and cast new lights on her idea of freedom, as well as her background and references. Approaches to the Theory of Freedom help us to become familiar with the way this magnificent poem becomes a defense of freedom. That is why this book means a significant contribution to our understanding of Sor Juanas thought and the poetry of Sor Juanas period.
