It occurred to me a while back that, as much as Gryffindor and Slytherin are sometimes portrayed as two sides of the same coin, Slytherin is just as much a foil to Hufflepuff as it is to Gryffindor. After all, ambition and work ethic go hand-in-hand. Both houses are more practical and focused on the real world, whereas Gryffindors and Ravenclaws tend to be more abstract and idealistic. And while Slytherins tend to be ruthless and harsh, whereas Hufflepuffs are kind and selfless, that’s certainly not universal. Zacharias Smith is far from selfless, and there’s nothing harsh or ruthless about Professor Slughorn. Both houses are even defined by their loyalties – or, rather, Hufflepuffs are defined by their loyalty, while Slytherins are the opposite: not necessarily disloyal, but very selectively loyal, fighting amongst themselves to prove themselves to Voldemort or betraying their side for a single person.
Couldn’t we also say, though, that Slytherin is a foil to Ravenclaw? Both houses value intelligence. However, with Ravenclaws it’s creativity, wisdom, and the pursuit of knowledge for its own sake that is valued. Slytherins, on the other hand, are sly and cunning, using their minds as weapons and their knowledge as a tool to help them get what they want. When I did my Divergent Sorting Hat Saturday posts, I found that most Erudite characters fit into Slytherin, even though their Faction aligns more closely with Ravenclaw at first glance. Even the mascots each reflect the other house’s traits if you know your heraldry: the snake was a symbol of wisdom, while the eagle represented power.
Is it fair to say that Ravenclaw and Slytherin represent two ways of valuing intelligence, that Hufflepuff and Slytherin represent two types of hard work and loyalty, and that Gryffindor and Slytherin represent two ways of taking action for what you think is important?
I talk a lot on this blog about how Slytherin doesn’t have to mean evil. I’ve sorted a lot of positive characters there (and a lot of negative ones into other houses). But within the series itself, looking at the contrast between the different houses, does it make sense to say that Slytherin is the “dark side” to all three “good” houses? I would say so.
