At the end of 21th Century, as result of the implementation of neoliberal policies, Costa Rica experienced an integral modification of the relations and social conditions of life; the relation structural-superstructural that supported the traditional scenario of daily life suffered a decline. The old and solid world of Costa Ricans lost his certainties. Uncertainty seizes existence. The centralization of meanings that supported life, thinking and the way people values hegemonies, lost compressibil- ity and coherence. This produced the consolidation of age groups, women, indigenous, emigrants and homosexuals as acting agents in a new scenario of daily life. For Costa Rican philosophy, the emergence of this new actors and human relations represents a challenge to develop a new type of philosophy: a hermeneutic of diversities. This new philosophy must configure a new social common sense, which integrate and dignifies people.
