Huarte was a distinguished Spanish physician and psychologist. His Examen, which gained for him a European reputation, was the first attempt to show the connection between psychology and physiology. English translation by Richard Carew as The Examination of mens wits (London, 1594), and Lessing translated the book into German. Over the next two centuries Examen was published "in six different languages: in Spanish fifteen times, twenty-five in French, six in Italian, five in English, three in Latin and one in Dutch. In total nine translators rendered this work into other tongues, and the book was printed in twenty different European cities" (Carew translation, edited by R. G. Sumillera; see No. 8705).

Includes a very significant historical introduction, particularly concerning the very wide influence of this work on literature and philosophy as well as medicine.
