At the end of the 19th century, Cardinal Mercier founded the Higher Institute of Philosophy (HIPh) in Louvain, an academic centre that sought to harmonise Thomistic doctrine with both modern science and philosophy. The Vasque priest Juan Zaragüeta Bengoechea was trained in the HIPh and occupied a prominent place in Spanish academic life during the first half of the 20th century, making important contributions to philosophy, pedagogy, psychology, and Spanish culture in general. This paper presents a portrait of Zaragüeta and briefly outlines some of the key aspects of his conception of psychology. [ABSTRACT FROM AUTHOR]
