Uncommon first edition in good condition, bound with the arms of Antoine Paul Jacques de Quélen de Stuer de Caussade, count, then 1st duke of La Vauguyon.
La Vauguyon who gives here a work of philosophy affirming that man is absolutely free of his choices and tends naturally towards his well-being, was tutor of the future Louis XVI and his brothers. We owe him this famous shortcut on his pupils whom he nicknamed "The 4 Fs": according to him, the Duke of Burgundy was the strong one; Berry, the weak one; Provence, the false one; Artois the frank one.
