THE highest use of the great masters of literature is not literary; it is apart from their superb style and even from their emotional inspiration. The first use of good literature is that it prevents a man from being merely modern. To be merely modern is to condemn oneself to an ultimate narrowness; just as to spend one’s last earthly money on the newest hat is to condemn oneself to the old-fashioned. The road of the ancient centuries is strewn with dead moderns. Literature, classic and enduring literature, does its best work in reminding us perpetually of the whole round of truth and balancing other and older ideas against the ideas to which we might for a moment be prone. The way in which it does this, however, is sufficiently curious to be worth our fully understanding it to begin with.
— GK Chesterton, On Reading (in the book called The Common Man)
