"There was an implicit value judgement in Greenfield's talk between the "purely sensory experiences" of raves or today's computer games, and the cognitive activities of reading a book or listening to a symphony, which, because they make us "see one thing in terms of another thing", involve a more mature mental engagement. For Greenfield, the Beethoven was a higher experience because it offered an "escape from the moment", where a rave was about losing yourself to the "thrill of the moment". I think that's a flimsy distinction, since both are about submitting to the sensory power of music. I'd like to see the difference in brain activity between somebody "escaping" life's mundanities and another person "thrilling" to the implacable now of the beat."
