Why Sociology is mixed with "Arts" I have no idea... Another curiosity: "Social Sciences", where I come from, means only Sociology, Anthropology and Political Science; that is, Psychology is a Human Science, but not a Social Science. Go figure!
The problem is not in the names themselves, but in what they mean. And yes, I used to make fun of my friends at the Exacts Branch all the time... :-)
PS: Sweetchic, it's the Oxford Concise.
