"Aline et Valcour, ou Le Roman Philosophique. Tome 3" by Marquis de Sade is an epistolary novel written between 1786-1789 while the author was imprisoned in the Bastille. The work interweaves the virtuous love story of Aline and Valcour with exotic travel narratives through southern Europe and Africa. At its heart lie two contrasting kingdoms: the brutal, cannibalistic African realm of Butua and the utopian Pacific island of Tamoé, ruled by philosopher-king Zamé—a philosophical exploration of vice versus virtue in radically different societies.
