The phrase "He who seeketh danger perisheth therein" from Miguel de Cervantes Saavedra's "Don Quixote" emphasizes the perils of recklessness and the consequences of pursuing dangerous undertakings. This idea suggests that those who are overly ambitious or naive in their pursuits may ultimately face harm or disaster, illustrating a cautionary message about the risks that come with the quest for glory or adventure.

In the context of "Don Quixote," this quote reflects the protagonist's misguided adventures as he boldly confronts imagined foes. His pursuit of chivalric ideals leads to hilarious yet dangerous situations, serving as a critique of romantic notions of heroism that may overlook the realities of risk and danger. Hence, Cervantes invites readers to consider the fine line between bravery and folly.
