I previously answered this question insufficiently

In our interviews last summer, Chilly asked me "Why Politics?" I answered something you may all see one day on a DVD- - - but the answer was flacid and uninteresting. Today in my political theory class I found a more suitable answer. I'll warn you that I am really dorky and this may seem lame/dry/boring/alloftheabove, but this stuff seriously gets me excited and so I wanted to share. (Disclaimer: This is Aristotle and I only understand it because a brilliant professor has lectured on it for 4 - 5 days... so take this for what you think it's worth. I don't necessarily agree with everything said, but I think the principle is incredibly interesting.)

"Knowledge of the good would seem to be the concern of the most authoritative science, the highest master science. And this is obviously the science of politics, because it lays down which of the sciences there should be in cities, and which each class of person should learn and up to what level. And we see that even the most honourable of faculties, such as military science, domestic economy, and rhetoric, come under it. Since political science employs the other sciences, and also lays down laws about what we should do and refrain from, its end will include the ends of the others, and will therefore be the human good. For even if the good is the same for an individual as for a city, that of the city is obviously a greater and more complete thing to obtain and preserve. For while the good of an individual is a desirable thing, what is good for a people or for cities is a nobler and more godlike thing. Our enquiry, then, is a kind of political science, since these are the ends it is aiming at." -Aristotle's Nichomachean Ethics
