There is no need at all to go to college to study liberal arts.
You can do it on your own for free. The funny thing is that the public is convinced that they have to spend tens or hundreds of thousands of dollars to read a book.
Wow. You are so wrong. Most of those books were written by persons who attended a
University or (in the distant past) had at least a single mentor. And today, most survey courses in the liberal arts can be taken at a Community College where the student can live at home and pay less per unit.
In a university graduate seminars allow one to study a narrow field with assigned reading and then spend a semester in a small group testing their own theories, getting and giving feedback, asking questions and answering them.
Liberal Arts allows one to study a single topic within the structure of different disciplines. For example, in my sophomore year I had separate courses in the Philosophy, Political Science and History departments all of which were focused on ancient Greece.
A Liberal Arts education provides perspective. A cure for myopic 'thinking' which dominates too many threads on the USMB.
