In "Harry Potter and the Philosopher's Stone," J.K. Rowling uses the Mirror of Erised as a significant plot device to delve into the innermost desires of Harry's heart, thereby fleshing out his character for the reader. The mirror shows the deepest, most desperate desire of a person's heart, a concept that is beautifully woven into the story to enhance Harry's depth as a character and to advance the narrative. When Harry discovers the Mirror of Erised, he sees himself surrounded by his family, specifically his deceased parents who he never had the chance to know. This reveals a few key aspects of Harry's character: 1. **Longing for Family and Belonging**: The image Harry sees reflects his profound sense of loss and yearning for the loving family he never knew. Despite his brave face and often stoic demeanor, it underscores that his deepest wish is for familial connection and to understand who he is and where he comes from. 2. **Innocence and Purity of Heart**: Unlike other characters who might see wealth, fame, or power (as Ron Weasley sees himself as a celebrated and successful individual), Harry's vision is not one of personal glory or ambition but of love and connection. This pure-hearted desire paints him as a sympathetic figure and highlights his innocence, setting him apart from characters who might fall prey to the more corrupting influences of desire. 3. **Conflict Between Desire and Duty**: The Mirror of Erised also serves as a narrative tool to develop the theme of desire versus duty. Dumbledore warns Harry about the dangers of becoming lost in dreams and forgetting to live, drawing attention to Harry's internal conflict. Harry must learn to balance his personal desires with the reality of his situation and his responsibilities, a key part of his growth as a character. 4. **Empathy and Relatability**: For the reader, Harry's longing to be with his family makes him an incredibly empathetic character. Many readers can relate to the pain of loss or the universal desire to be loved and to belong, which strengthens the emotional connection between Harry and the audience. As a result of these revelations, Harry becomes a more three-dimensional character, and readers are offered deeper insight into his motivations and vulnerabilities. This moment in the story, where Harry encounters the Mirror of Erised, thus becomes critical in shaping our understanding of him and charting his development as a protagonist who must grapple with his inner desires while facing grand external challenges.
