Earlier quoted context omitted.
It's equally rare to meet someone whose undergraduate education takes them to the places that a simple undergraduate education will. I'm 23, so I have plenty of friends and coworkers who are just recently out of state schools, and the vast majority sure as hell don't remember the classic novels that they might have skimmed over the course of two weeks, three years ago. I generally can't detect that they know anything…
Which is why I intentionally used the word "exposed":) I can't really recall very many specifics from my world literature classes either. However my psychology class taught me that the exposure to those novels and their concepts informs my decision making in some small way even today.
I'm somewhat ambivalent on the question of whether my liberal arts education actually made a difference in my life, but "because I heard it in psych class" would be at the very bottom of my reasons to believe so. If you're going to hold the opinion that a liberal education teaches you how to learn and informs all your future decision-making, hold it because experiences have corroborated that, not because you read in a psych textbook that that's how it's supposed to work. Textbooks do lie, y'know. ;-)
Otherwise - well, you haven't really learned how to learn, have you? If the point of a liberal education is to make sense of the world around you and form your own opinions, and you're still regurgitating things you read in a book, that liberal arts education has failed.
