Abstract
After the last very deep and intense investigations on Zubiri’s thought carried out in recent decades, this essay aims to contribute to make an assessment of the current state of the matter, examining several fundamental problems concerning human knowledge, which has been masterfully elucidated by the Spanish thinker: the question of truth and its modalities; the link between truth, knowledge and reality (the question of realism, types of scepticism and the question of hermeneutic). It is also about seeing the question of the limits and possibilities from human Knowledge, attending to the articulation between human cognitive activity and the ontological structure of man (spiritual and corporeal at once). All of this is about seeing the achievements of Zubiri’s approach - placing his proposal in the context of the history of Western thought, and in particular, in the context of current thinking - emphasizing the possibilities it opens in the future, but its difficulties too.
