This quote, often attributed to Albert Einstein, argues that fairy tales are not mere entertainment but a powerful tool for developing a child's intellect. It suggests that imaginative stories cultivate creativity, curiosity, and the capacity for abstract thought — qualities essential for deep intelligence. By encouraging repeated exposure to such narratives, the quote challenges the notion that only factual or "serious" learning builds a sharp mind. Its enduring popularity reflects a widespread belief in the value of nurturing imagination alongside analytical skills.
