It was necessary for the purposes of a clerical education, that he should quit his paternal roof. There was a university at Cahors, not far distant, and the abbé de Fénélon (as he was then called) was sent there, at the age of twelve. He did not at first enter on the course of philosophy; although sufficiently advanced, it was feared that his young mind was not as yet capable of the attention that it required, and that he might be disgusted by its dryness, and the difficulties presented. He began, therefore, with a course of rhetoric, which forced him to retread old ground, and to relearn what he already knew. Being so well advanced, he was, of course, greatly superior in knowledge to his equals in age: but this excited no vanity; he felt that he owed the distinction to the cares bestowed on his early years. By the age of eighteen, he had finished his course of theology; he took his degree in the university of Cahors, and returned to his family.
The marquis de Fénélon, his uncle, invited him to his house in Paris, and treated him as his son. The marquis was lieutenant-general of the armies of the king, a man of distinguished valour, and a friend of the great Condé, who said of him, that "he was equally qualified to shine in society, in the field, and in the cabinet." He added piety to his more worldly qualities, and soon perceived and took pride in the admirable dispositions of his nephew. At the age of nineteen, the abbé preached sermons that were generally applauded. This success alarmed his uncle. He perceived the pure and upright character of his nephew; but, aware of his sensibility, he feared that public applause might spoil him, and substitute vanity for the holy love of duty that had hitherto actuated his conduct. From these reasons, he counselled him to retire from the world, and to enter a seminary, where in solitude and silence he might cultivate the virtues best suited to an ecclesiastic. Fénélon yielded; he entered the seminary of Saint Sulpice, and put himself under the direction of the abbé Tronson, who was its superior-general. The house was celebrated for its piety, its simple manners, its pure faith, and, added to these, its studious and laborious pursuits. He passed five years in this retreat, devoted to his duties and to the acquirement of knowledge. Thus were the ardent years of early youth spent in religious silence and obedience--in study and meditation. There was no worldly applause to flatter, no fame to entice; his happiness consisted in loving his companions, and being attached to his duties. His mind became strengthened in its purposes by example, and his virtues confirmed by habit. At the age of twenty-four he entered holy orders; and his future destiny as a priest was unalterably fixed.
