The different receptions of the work of Martin Heidegger represent a significant aspect to understand the evolution of the Spanish Philosophy of the second half of century XX. In a context of crisis of the modernity and the search of a philosophical solution up to the task of its time period, the philosophical reception of Ortega was polemical and has been object of different interpretations. Early received by his disciples Zubiri and Gaos, and of special relevancy for Zambrano, the work (...) of Heidegger contributed to oust both Ortega and his heritage during the times of Madrid School during Francoist dictatorship. From the scholastic philosophy of the forties, and from Heidegger his-self, he abandoned The Idea of Principle in Leibniz, work that has been just published as a new official edition including previous work notes. In this way, in our work we will make a critical itinerary about that initial reception and its most relevant readings, this time analyzed under the methodological frame provided by the Sociology of Philosophy.
