One of the most beautiful "old" books to read (especially if English is your native tongue) is John Locke - Essay Concerning Human Understanding. It's a beautiful piece of text, more so if you can get an old Oxford Claredon Press edition edited by Peter Nidditch. I've read that Nietzsche and Schopenhauer are also delightful to read in the original. Schopenhauer's writing style is so good, even when translated to English by Saunders.
