A polygraph and philosopher, the marquis de Caraccioli endeavors in this work intended to illuminate certain enigmas of Christian faith, to construct the foundations of a modern faith in accordance with the Enlightenment, thereby strongly opposing the deists. A preface was added for the second edition of le Mentor. This treatise on education had considerable success, more than all the marquis's other books; it bases educational excellence on a good tutor, and accuses the era of not producing great men for want of sound education.
