Harry begins the story as a very insecure young boy; he has been mistreated and neglected by his aunt and uncle. He also does not really feel as though he belongs any where. As Harry meets Hagrid for the first time, Hagrid is shocked to discover that the Dursleys have never told Harry anything about his true potential
“Do you mean ter tell me," he growled at the Dursleys, "that this boy—this boy!—knows nothin' abou'—about ANYTHING?" (chapter four)
Learning that the was part of a secret world of magic astounds Harry, but he accepts his new role, gladly relishing the chance to be a part of something and learn about who he really is. Identity becomes an important theme in Harry Potter and the Sorcerer's Stone. Ultimately, Harry comes into his own and begins to trust himself and his new friends by the end of the novel when they must make their way past the challenges and obstacles lying before the philosopher's stone.
In this first Harry Potter book, Harry is on the initial part of his journey of self-discovery - learning about who he is, his background and his purpose in life. This journey is developed throughout the remaining books, tracing Harry's journey to adulthood.
In addition, he learns the importance of teamwork and friendship - without which he would not have found the Sorcerer's stone.
