1
used to imply that a foolish person will remain foolish no matter how many opportunities or experiences they have
The origin of the proverb "send a fool to market and a fool he will return" is found in early English literature, with variations appearing in works from the 16th century. The proverb reflects the idea that no amount of experience or exposure to new situations can change someone's inherent lack of wisdom or good judgment. It serves as a reminder that certain qualities, such as foolishness, are deeply ingrained and difficult to change, regardless of external influences or experiences.
