Under the pretense of defending an obscure treatise by a Catalan theologian, Sebond, Montaigne attacks the philosophers who attempt rational explanations of the universe and argues for a skeptical Christianity based squarely on faith rather than reason. The result is the Apology for Raymond Sebond, a classic of Counter-Reformation thought and a masterpiece of Renaissance literature.This new translation by Roger Ariew and Marjorie Grene achieves both accuracy and fluency, conveying at once the nuances of Montaigne’s arguments and his distinctive literary style.
