Abstract

Philosophy is the search of truth. This means that philosophers are those which are looking for the truth, no matter where it could be. As a consequence, the study of previous philosophers can only have the role of an aid in order to reach this task. They are only means, not ends in themselves. The rest is ‘scholasticism’. As a true philosopher, Zubiri was changing all his life his mind and progressing in the analysis of reality. In this paper some important differences between their two major works, On essence (1962) and Sentient intelligence (1980-1982) are analyzed. At the first glance it seems that both are talking about the same, ‘reality’, but the first is the analysis of what Zubiri calls ‘real-thing’ (cosa-realidad), while the goal of the second is the description of ‘reality’ as such, understood as the formality of the intellectual human approach to things. This difference, which seems minimal at the beginning, is at the end plenty of consequences, not only in the field of Metaphysics, but also in Anthropology and Theology.
