About the author

Born in 1676 in Galicia, Benito Jerónimo Feijoo entered the Benedictine order and spent much of his career in Oviedo. He became known not just as a monk and scholar, but as a gifted public writer who wanted learning to reach ordinary readers rather than stay locked inside universities and monasteries.

His most famous books, Teatro crítico universal and Cartas eruditas y curiosas, gathered essays on medicine, science, history, religion, and everyday beliefs. Again and again, he tested popular claims against evidence and argument, earning a reputation as a patient debunker of errors, superstitions, and fashionable nonsense.

Feijoo died in 1764, but his influence lasted well beyond his lifetime. He is still remembered as a major figure in 18th-century Spanish thought: a writer who made curiosity feel practical, skepticism feel humane, and serious ideas accessible to a broad reading public.
