Wanderlust World Wanderlust World The definition of "folly" has shifted subtly over centuries while retaining its core essence: foolishness, unwisdom, or impracticality.
Historically, "folly" carried heavy moral and ethical weight, describing actions deemed sinful, reckless, or contrary to divine wisdom—think of the "fool" in biblical wisdom literature. In medieval and Renaissance literature, folly was often personified as a character representing human absurdity (e.g., Erasmus's In Praise of Folly).
Today, the term has lightened considerably. It's frequently used in a humorous, affectionate, or architectural context ("a decorative folly in the garden"). Yet the fundamental idea—an action or idea lacking good judgment or practical value—remains unchanged. Whether describing a disastrous military campaign or a whimsical garden pavilion, "folly" still marks the boundary between wisdom and its absence.
