I don't know if Einstein specifically studied any of the "Liberal Arts" in college, or not. But what if he didn't? Is it necessary to take a formal class of study in a particular subject, in order to be able to appreciate it? I majored in physics and geology, but I still understand the importance of chemistry, biology, and the Arts.
The purpose of obtaining a liberal arts education, is to acquire general knowledge, and more importantly, to develop intellectual skills. It is primarily about learning how to be an independent thinker. Historically, a liberal arts education consisted of the study of several subjects, including philosophy, literature, languages, history, math, and science. Over the years, however, it seems as though math and science have been spun off by many universities into their own department. This has created a sort of "rift" in the educational system, and we see it in this thread. It's us (scientists) against them. And I think that is a damn shame.
The written and spoken language is how we convey ideas and thoughts. And learning to master that language is surely beneficial to anyone's life. Someone who speaks eloquently, most assuredly makes a better impression than someone who doesn't. Could any book be written without some ability to articulate ideas? Imagine trying to comprehend a technically correct, but poorly written, physics or math textbook. Imagine trying to write a technical paper, without having the ability to clearly express your ideas and theories.
Think about the subject of history, for a moment. Imagine if we had no knowledge of what happened in the world last week, or last year, or five hundred years ago. Or imagine a world without any philosophical thought. Philosophy, a word of Greek origin, which literally means "love of wisdom".
Imagine having no books to read, plays to see, music to listen to, news to comprehend, or Star Trek to watch. Read any of the classic books, and tell me they are a waste of your time. Take The Count of Monte Cristo, for example. A brilliant work of art, written by Alexandre Dumas, more than 160 years ago. 1300+ pages, not one of which, is boring or repetitive. Only a creative mind and master of the written language could have penned such a wonderful story.
The Arts (liberal and fine) enhance our lives. I'm not sure I would want to live in a world without them. Closing your mind to the Arts is so self limiting. And so sad.
