Alongside those of life and circumstantiality, the notion of profoundity emerges as one of the most significant in Ortega y Gasset’s philosophy. He examines it in a specific and detailed manner in Meditaciones del Quijote (1914) and refers to it in more than twenty of his works. Moreover, it is a concept that informs some of his most important and influential philosophical ideas. This article seeks to analyse Ortega’s conceptions regarding the nature and meaning of the profound, its characteristics, and its importance.
