The nearest I have yet got to an answer [to the question of why we should read] is that we seek an enlargement of our being. We want to be more than ourselves. Each of us by nature sees the whole world from one point of view with a perspective and a selectiveness peculiar to himself. And even when we build disinterested fantasies, they are saturated with, and limited by, our own psychology… We want to see with other eyes, to imagine with other imaginations, to feel with other hearts, as well as with our own. We are not content to be Leibnitzian monads. We demand windows. Literature as Logos is a series of windows, even of doors. One of the things we feel after reading a great work is “I have got out.” Or from another point of view, “I have got in”; pierced the shell of some other monad and discovered what it is like inside.
…[Literature] admits us us to experiences other than our own… It may be beautiful, terrible, awe-inspiring, exhilarating, pathetic, comic, or merely piquant. Literature gives the entree to them all. Those of us who have been true readers all our life seldom realize the enormous extension of our being that we owe to authors… My own eyes are not enough for me.
…In reading great literature I become a thousand men and yet remain myself. Like the night sky in a Greek poem, I see with a thousand eyes, but it is still I who see. Here, as in worship, in love, in moral action, and in knowing, I transcend myself; and am never more myself than when I do.
