La Mothe le Vayer, François (1588–1672)

French man of letters. Born in Paris, he was preceptor to the duc d'Orleans and also later, for a time, to his elder brother, the young Louis XIV, and wrote a series of manuals for the prince, such as La Géographie du prince 1651 and La Logique du prince 1658. He also published various discours, petits traités, and (under the pseudonym Orasius Tubero) Dialogues which continue the Pyrrhonism of Montaigne and the scepticism of the freethinkers.

In his Considérations sur l'éloquence française de ce temps 1638 he criticized the French grammarian Claude Favre de Vaugelas (1585–1650), who replied in the preface to his Remarques sur la langue française 1647.
