Free University Courses on the Internet
I just happened upon this list of free courses on the Daily Kos. There are plenty of courses covering many subjects at many top notch universities.
Yale University Prof. Tamar Gendler lectures on Aristotle: Virtue and Habit
Aside from Yale, MIT, U. of Michigan, Notre Dame, U. of California and many others offer free courses. Outside the U.S. there are many resources as well including the University of Capetown. If you are just interested in learning and not paper credentials the Internet is a treasure trove of free quality material. Again the link to the list is here.
