Amsterdam, Chez Pierre Mortier, 1746; two volumes in 12, basane fauve jaspée, spines decorated with red morocco, arms stamped in the center of the boards, red edges. First edition of Condillac's first book, which immediately brought glory to its author. Copy with the arms of Alexandre de la Rochefoucauld, duc de la Rochefoucauld, 1690-1762, who first embraced a military career, then became grand master of the king's wardrobe, but was disgraced in 1744.
