As exercise becomes tedious and painful when we make use of it only as the means of health, so reading is apt to grow uneasy and burdensome, when we apply ourselves to it only for our improvement in virtue. For this reason, the virtue which we gather from a fable, or an allegory, is like the health we get by hunting; as we are engaged in an agreeable pursuit that draws us on with pleasure, and makes us insensible of the fatigues that accompany it.
Joseph Addison (1672-1719) English essayist, poet, statesman
Essay (1709-03-18), The Tatler, No. 147
