Victor Davis Hanson of Works and Days has a must-read post on why reading great books on a regular basis is essential. I believe he also make the case, without actually stating so, for liberal education. A sample:
The mind is a muscle. Without exercise, it reverts to mush. Watching most TV or using the normal electronic gadgetry does not tax us much — indeed that is by design the very purpose: to eliminate effort, worry, unease, and afterthought. None of us thinks back a year ago to a great video game session. Few off-hand can recall the Super Bowl winner of 2001. I remember the scenes in a Shane or Casablanca, but not many others in the other thousand of movies that I have watched.
By nature, our ways of expression and even thinking always fossilize and are withering away with age and monotony — a process accelerated by the modern electronic age and the neglect of replenishment through reading. The actual vocabulary of our present youth seems to me reduced to about 1,000 words or so. “Like,” “whatever,” “you know,” “cool,” and other pop culture fillers now substitute for entire phrases, a sort of modern porcine grunting. The Greeks used particles to accentuate vocabulary and guide syntax; we used them instead of vocabulary. Our syntax, both written and oral, is reverting to “Spot is a dog”: noun, verb, predicate — period. How did incomprehensible slang, spiced with vulgarity, become an object of emulation? I used to listen to farmers without college degrees speak wonderful English; now to listen to a member of Congress almost requires a translator.
Reading alone enriches our vocabulary; it teaches us that good writing requires a sense of melody as well as a command of grammar. Soon those well-read become the well-spoken.
