“And once the novelist has brought us to this state, in which, as in all purely mental states, every emotion is multiplied ten-fold, into which his book comes to disturb us as might a dream, but a dream more lucid and more abiding than those which come to us in sleep, why then, for the space of an hour he sets free within us all the joys and sorrows in the world, a few of which only we should have to spend years of our actual life in getting to know, and the most intense of which would never be revealed to us because the slow course of their development prevents us from perceiving them. It is the same in life; the heart changes, and it is our worst sorrow; but we know it only through reading, through our imagination: in reality its alteration, like that of certain natural phenomena, is so gradual that, even if we are able to distinguish, successively, each of its different states, we are still spared the actual sensation of change.”
