The spirit of humanism no longer lives in Classics. The two are not mutually exclusive by an means, but they are distinct. Classics is more of a modern, "scientific" endeavor--an observation of things classical. Latin (and Greek), therefore, is more of a tool of the trade. It is akin to the scientist's microscope. It gives him insight to another world, but it is not a goal in itself. Thus most classicists are perfectly content to be able merely to read Latin, but they read (usually by translating into a quasi English-Latin hybrid) just to get the info. Style and beauty of expression are seldom noticed or appreciated. I do not say never, but seldom and only secondarily.The spirit of humanism, on the other hand, is not primarily observation, but participation in things classical. This, I believe, is the distinguishing factor. Humanists don't just observe, they want to participate in Latin (and Greek). They don't just want to translate Latin to cull information; they want to read Latin, appreciate its beauty, speak it, live it. That sort of activity is the goal of humanism: improving the self, participating in studia humanitatis.
Sic. Which means that Greek and Latin aren't even at home in their own living room any longer. The Wittenberg approach to classical antiquity is not dissection, but living appropriation.
