In Praise of Folly (Latin: Moriae Encomium or Stultitiae Laus) is an essay originally written by the great Dutch classicist Desiderius Erasmus while staying in London with Sir Thomas More, who is the subject of a punning reference in its Latin title.
The work is written from the perspective of Folly herself, whose self-praise provides the vehicle for a wide-ranging satire of contemporary society.
