It’s easy to read the Harry Potter series as an allegory for trauma and recovery. Harry is psychologically scarred by the murders of his parents, leaving him vulnerable to external pressures – a condition we see most clearly in “The Prisoner of Azkaban.” As a result, though, others in his support network make special accommodations for him, teaching him advanced protective spells, feeding him emergency chocolate, and generally supporting him when necessary. The series, then, is a refreshingly optimistic story of how a young boy learned to overcome an sometimes crushing disability.
At the same time, though, it could be argued that his traumatic past is never Harry’s true disability. There’s a clear way in which being an immigrant in a foreign land is a disability in itself, and that’s exactly what the “muggle-raised” Harry is. His ignorance of the wizarding world makes him an endlessly useful literary device for Rowling, but it also makes him an eternal outsider, even when surrounded by his friends. Throughout all seven books, Harry has to familiarize himself with simple concepts like candy and receiving letters; his constant struggle is not just to fit in, but also simply recognize what he’s trying to fit in to – a struggle that’s still ongoing at the end of the series.
Are Harry’s friends and mentors as accommodating of this disability? They certainly seem helpful enough, but their help usually amounts to little more than above-average patience. They explain bizarre objects and creatures as they appear, on a sort of “need to know” basis, but I’m sure that even they recognize the futility of trying to explain everything. Their support is more reactionary than preventative of confusion.
Harry’s trauma physically manifests itself in the form of his scar, a constant reminder to others of one of the disabilities he faces. It signifies to others that he is someone special, and the physical pain it causes cues others that Harry is in need of protection. Harry’s more fundamental disability, however, lacks any physical sign other than his awkward cluelessness. Perhaps this is why it gets swept under the rug. The main focus of the series seems to be Harry confronting his demons and recovering from his trauma; he succeeds in this, but he’ll probably fight the battle against his endless otherness for the rest of his life.
