This week’s survey by the National Endowment for the Arts “indicates that people who read for pleasure are many times more likely than those who don’t to visit museums and attend musical performances, almost three times as likely to perform volunteer and charity work, and almost twice as likely to attend sporting events. Readers, in other words, are active, while nonreaders — more than half the population — have settled into apathy. There is a basic social divide between those for whom life is an accrual of fresh experience and knowledge, and those for whom maturity is a process of mental atrophy. The shift toward the latter category is frightening.”
