Rowling uses the various settings of Harry Potter and the Sorceror's Stone to address Harry's perception of himself. In the novel, Harry's sense of identity as a person is very closely tied to his environment. When he is at the Dursley's living in their broom closet, Harry feels undervalued and out of place, but as soon as he learns of his 'secret' heritage as a wizard and takes his rightful place at Hogwarts School of Witchcraft and Wizardry, Harry begins to establish his new identity as a valuable member of wizarding society.
Sense of place becomes extremely important as Harry searches for his role within Hogwarts and the wizarding community; children often identify themselves with their surroundings, and Harry is no exception. As he begins to assert himself and take charge of his own destiny, Hogwarts begins to feel like the home he has never had.
