Abstract
This article is a tribute to Prof. Jorge Ayala, to his kindness and integrity, in both a personal and intellectual sense. In order to contextualise the meaning of Ayala’s contribution, this article refers to a particular conception of coherence between thought and existence which can be traced in part to the main course of Western intellectual history: a way of experiencing the thought, values and beliefs through which our intellectual choices reflect a way of being –an understanding which is very close to Baltasar Gracián’s notion of «moral truth».
