Yes.I don't believe there is enough emphasis on liberal arts. Liberal arts is more than just memorizing a series of data and regurgitating it later. Knowledge retention is and has been looked at extensively, and in my field it's of particular importance since in physics many students who take it will end up retaining nothing. However, there is a more important aspect associated with liberal arts and that comes through the use of critical thinking. And it's here that one can say one of the true powers of liberal arts education lies. Even if we forget what we've memorized, we are able to keep the critical thinking. Liberal arts should teach people to question and think about answers more so than learning which way to turn a wrench to loosen a bolt (I use the right hand rule). The ability to critically think is something which I feel is really leaving the American populace. Too much people want to opposite of liberal arts education, they want to know how what they're learning is going to fit into the cog necessary to do their job; and that's not so much liberal arts as it is more accurately labeled as vocational. That focus I fear has driven away intellectual and academic pursuit and has caused us to lose a lot.
In the end you don't just want a cog. A cog can be replaced with an appropriate robot. You want thinkers, you want people who can analyze and question circumstances, who can weigh out the data in front of them and come up with intelligent solutions. It's imperative not just for the success of the individual to be able to think, but for the Republic as a whole. And on this front, we should be doing more.
And the point is training the mind to reason critically and solve problems, not to learn a trade.
