Meta-meta: some thoughts on the limitations of viewing Snape as a nerd
Original poster: peignoir
this is partly a response to this essay, this essay, and this thread.
My discomfort with analyzing Snape as an instance of the nerd archetype comes from the fact that I see it as an insufficient description. I'm not saying that it never makes sense to look at Snape in the context of the nerd in fiction, or say that a few aspects of Snape's personality could be described as nerdy (it does help to explain his intellectual motives for studying the Dark Arts, for instance). But there is also something diagnostic about the term: it covers a constellation of traits without revealing something more about what the sum of them means. What information does it add about Snape and his experience to call him a nerd? On the other hand, what information is reduced or left out by this reading?
Snape is too much to describe using the nerd archetype, I think. The nerd carries a connotation of ivory-tower intellectual detachment, a sense of being not quite of the world. Snape is anything but—he's entangled in the world. He chooses, he acts; there's blood on his hands. The primary journey his character makes is a moral one, not a truth-quest. The archetypal nerd also tends to be the benign victim of bullying at school, so associating Snape with this identity puts the emphasis on the passive, victimized side of Snape, and gives too little attention to the active side. We identify with the lonely nerd, or at least many of us do; perhaps calling him that exculpates him a little—maybe these essays hope to reach other readers and convince them to view Snape with the same empathy that we already do. But it's actually his culpability, that responsibility for his choices from which he can't be fully excused, that makes his character remarkable by giving him the heaviest of burdens. While some parts of his character may be illuminated by looking at him through the nerd lens, others, like his central moral entanglement with the world, get obscured.
Other, relatively more minor, aspects of Snape's character are also excluded: what can a Snape-as-nerd reading say about the Snape who was taken under the wing of Lucius Malfoy, who learned to affect membership in the upper class well enough to shock Bellatrix when she first saw his house? About his skill in Legilimency and ability to hold a class's attention without effort, proof of his instinct for people? About the Snape who may have maligned Quidditch jocks, but was also the only faculty member besides Madam Hooch whom we know was qualified for refereeing, and whose ability to fly unsupported suggests some physical grace and skill? About the eloquent, droll conversationalist and the convincing actor?
