One criticism of some schools with very classical education is their lack of preparation for the "real world". Many schools didn't bother teaching computer skills until years after the rest of the world had started, despite having the means (i.e. money) to do so. Learning the classics, learning Latin, and learning poetry can make someone an excellent guest at a dinner party, and that's great, but I think the average person would be better off with a little more practicality.
Einstein said, "Education is what is left after you've forgotten everything you've learned." Isn't it all about teaching a sort of... meta-skill? Teaching people to learn how to learn? When they no longer remember what Lord of the Flies was about or not being able to recite The Raven, they should still be able to retain the skills required to go back, look at the writing, and figure it out again. I would argue that it should be the same for things like rhetoric. When you're 26 and you have to give a speech at work for the first time in ten years, you should remember some stuff from high school. You may forget the lame topic you were assigned to give a speech on, and you may forget what sources you used, but the skills of doing that research, preparing that speech, and talking in front of others all helped you. Not only do they help with that speech at work, but also in normal, everyday conversation. I really think there's a good case here for teaching some more practicality, despite my love of all the things I learned in my English classes.
Of course, it should be noted that I am not in the educational field and I am a complete layman on this topic.
Until I turned 30 I never understood the point of learning poetry in school. My mother got ill, and I recalled the poem "Do not go gentle into that good night" by Dylan Thomas, and it helped me make sense of my feelings. When politicians equivocate, I am reminded of a core theme in Macbeth. I have never discussed Macbeth at dinner, but it helped me understand an important aspect of the world. My English teachers helped give me a framework for understanding as an adult, though their analysis of the literature we studied. I taught myself computers at home, and studied CS at university, but I am glad that we did an intensive study of the English language in high school. School is the last opportunity for many people, particularly those who are technically inclined, like me, to be exposed to the humanities, and without it, we are at risk of being stunted as adult citizens. (Incidentally, it has been pointed out that many modern terrorists have engineering backgrounds- perhaps it is even more important for us to be exposed to the classics to help make sense of the world.)
"Who is the most original and the most versatile intellect that the Americas have so far produced? The answer "Charles S. Peirce" is uncontested, because any second would be so far behind as not to be worth nominating. [He was] mathematician, astronomer, chemist, geodesist, surveyor, cartographer, metrologist, spectroscopist, engineer, inventor; psychologist, philologist, lexicographer, historian of science, mathematical economist, lifelong student of medicine; book reviewer, dramatist, actor, short story writer; phenomenologist, semiotician, logician, rhetorician and metaphysician.
He was, for a few examples, the first modern experimental psychologist in the Americas, the first metrologist to use a wave-length of light as a unit of measure, the inventor of the quincuncial projection of the sphere, the first known conceiver of the design and theory of an electric switching-circuit computer, and the founder of "the economy of research." He is the only system-building philosopher in the Americas who has been both competent and productive in logic, in mathematics, and in a wide range of sciences. If he has had any equals in that respect in the entire history of philosophy, they do not number more than two."
