how does the novel harry potter prove that friendship and bravery is indeed more important than intelligence(referring to hermione's qoute in philosophers stone)

Throughout the book, Rowling expresses the importance of friendship, particularly when it comes to overcoming challenges and difficult tasks. Before coming to Hogwarts, Harry is completely isolated. Not only does he not have a loving family environment, but he does not have any friends to serve as a support system. After becoming a student at Hogwarts, however, Harry quickly creates a large group of friends but, more importantly, a close relationship with Ron and Hermione. For most of the students at Hogwarts, a strong group of friends helps with homesickness and difficult classes. Yet, in Harry's case, Rowling draws a more obvious parallel between friendship and difficult life challenges: the only way that Harry is able to reach the Mirror of Erised in the dungeons of Hogwarts is with Ron and Hermione's help. Hermione and Ron both tackle specific challenges that Harry would have been unable to face on his own, specifically Professor McGonagall's challenge of the giant wizarding chess and Professor Snape's challenge of the potions. In this case, Harry's friendship with Ron and Hermione saves his life and allows him to keep Voldemort from finding the Sorcerer's Stone.

Harry's friendship with Ron and Hermione is also significant in the way that it further distinguishes Harry from Voldemort. Although Voldemort is far more powerful than Harry, he prefers to be isolated and independent from those around him. Even Professor Quirrell, who drinks unicorn blood for him, is nothing more than a servant to Voldemort. Because Voldemort lacks the ability to form lasting friendships, he is always alone and has only himself to rely on. Harry, on the other hand, is able to rely on himself while still drawing upon the support system and exceptional magical talents of his close friends.
