Modernity based on reason postulated utopian societies where justice, equality, fraternity and peace would reign in contrast to events such as the 30 Years War in Europe and the exploitation and discrimination produced by the feudal regime and absolute monarchies. Modernity had an important development through industrialization, the construction of nation-states and the republican political regime, using science and technology as the fundamental lever of development and social progress. However, it has also shown contradictions, crises and facts that escape the rational and express that irrationality in many moments overflows rationality.In the face of these contradictions and crises, various critical currents and movements have arisen in poetry, painting, literature and architecture, and lately in philosophy, which appeared as postmodernism (literary current) and is now becoming a philosophical current with pretensions of having a civilizing scope, which is called postmodernity.
