This book covers much of the History of Modern Philosophy, from the birth of Nicolas de Cusa to the death of Rousseau. It examines, therefore, the broad period between the emergence of Renaissance philosophical currents to the full maturity of the Enlightenment tradition, paying due attention to philosophical movements traditionally known as "empiricism" and "rationalism." The work, which uses different exposure procedures, always giving priority to the narrative thread, not only emphasizes figures that, as in the case of Nicolas de Cusa, have not been sufficiently received in Spanish historiography, but also presents other more Fortunate (Descartes, Locke) in a novel way. Finally, the work brings a considerable amount of information, highlighting the relationship that philosophy holds with other aspects of contemporary culture.
