“Feelings are not as old as time. Just as there was a first instant when someone rubbed two sticks together to make a spark, there was a first time joy was felt, and a first time for sadness. For a while, new feelings were being invented all the time[…]It’s also true that sometimes people felt things and, because there was no word for them, they went unmentioned. The oldest emotion in the world may be that of being moved; but to describe it– just to name– must have been like trying to catch something invisible[…]Having begun to feel, people’s desire to feel grew. They wanted to feel more, feel deeper, despite how much it sometimes hurt. People became addicted to feeling. They struggled to uncover new emotions. It’s possible that this is how art was born. New kinds of joy were forged, along with new kinds of sadness: The eternal disappointment of life as it is; the relief of unexpected reprieve; the fear of dying. Even now, all possible feelings do not yet exist. There are still those that lie beyond our capacity and our imagination. From time to time, when a piece of music no one has ever written, or a painting no one has ever painted, or something else impossible to predict, fathom, or yet describe takes place, a new feeling enters the world. And then, for the millionth time in the history of feeling, the heart surges, and absorbs the impact.” --from Nicole Krauss' 'The History of Love'
