one answer to this (and other ascetical puzzlers) can be found in the biography of st francis of assisi by gk chesterton.
chesterton points out that the church in the early medieval period experienced a very deep cleansing in the form of the ascetic, desert living, fasting, anti-pleasure monks and nuns.
he points out that in rome, all of the pleasures had been indulged in with such abandon, in such excess, and attributed to so many pagan gods, that every pleasure became, at least in their minds (and culture) tainted by the associations they conveyed.
to combat this excess, and to purify the collective mind (the zeitgeist, if you will) of the church, they engaged in extreme fasts and abstinences. after a time, this began to balance back out to a healthy combination of pleasure and mortification.
you see the same thing happen in a young christian. they take their faith VERY seriously, and often burn their secular music or abstain from any books that aren’t spiritual and avoid movies and so forth, to purify themselves from the ‘worldly influence’.
then, with maturity, most of them learn that taking things in moderation and learning a healthy appreciation of pleasure and good books, music, and movies is completely consistent with our call to holiness and to following our Lord.
both are good - the ascetic and the appreciation of beauty and goodness. there is a time for everything - turn, turn, turn.
