 Francisco Sanches/Sánchez (1551–1623) was a physician and a philosopher. As professor of both medicine and philosophy at the University of Toulouse, he was the author of a number of treatises on both medicine and philosophy, but gained notoriety as the sceptical philosopher who penned Quod Nihil Scitur (1581), or That Nothing is Known (1988, TNK). As a philosopher who took a sceptical view of knowledge, and who famously ended his writings with the Latin interrogative “quid?” even the question of whether he was Portuguese or Spanish by birth, has been the subject of much debate. This has led to the confusing dual spelling of his last name: with an “s” by Luso-Brazilian scholars (Sanches); with a “z” by Spanish scholars (Sánchez); and commonly with an “s” (with some exceptions) by English-language scholars. Here the latter spelling will be used solely in keeping with English language scholarship and translations, while referring to Sanches, as an Iberian philosopher. This confusion over his rightful birth place, is curiously reflected in Elaine Limbrick’s Introduction to That Nothing is Known, where she refers to him as “the Portuguese philosopher and doctor” on page 1 and then a few pages later writes that “Francisco Sanches (Franciscus Sanchez) was probably born on July 16, 1551, in Tuy, a city of northwestern Spain…” (Limbrick 1988: 4): situated across the border from the Portuguese city of Braga, with which it shared an archdiocese (Cazac 1903, 1904). Supposedly, a distant cousin of Michel de Montaigne, and born to a family of “conversos” (Orden Jiménez 2012, in Other Internet Resources), in 1562 the Sanches family moved to the Bordeaux region where the cultural and political climate was much more amicable towards Jews and converts (Limbrick 1988: 5). It was in Bordeaux that Sanches attended the prestigious Collège de Guyenne between the years 1562 and 1571. The Collège de Guyenne, whose course of study ranged from secondary school to college, included a curriculum that emphasized the rhetoric of Aristotle and the scholastics.
