About the author

Born around 1550 and dying in 1623, Francisco Sanches was a Hispano-Portuguese physician, philosopher, and author often linked with Renaissance skepticism. He came from a family of Sephardi Jewish background and spent his early years in the Iberian world before building much of his career in France.

He studied medicine at Montpellier and later taught philosophy and medicine in Toulouse. His best-known work, Quod nihil scitur (That Nothing Is Known), argued against easy claims of certainty and pushed back on inherited scholastic authority, especially the dominance of Aristotle.

What makes his work memorable is the tone as much as the argument: curious, critical, and unwilling to accept ideas just because they were traditional. For listeners interested in the history of doubt, science, and independent thinking, he offers a fascinating bridge between Renaissance learning and later modern philosophy.
