Ernest Hemingway book A Moveable Feast
Source: A Moveable Feast (1964), Ch. 8: 'Hunger Was Good Discipline'
Context: You got very hungry when you did not eat enough in Paris because all the bakery shops had such good things in windows and people ate outside at tables on the sidewalk so that you saw and smelled the food. When you were skipping meals at a time when you had given up journalism and were writing nothing that anyone in America would buy, explaining at home that you were lunching out with someone, the best place to do it was the Luxembourg gardens... There you could always go into the Luxembourg museum and all the paintings were heightened and clearer and more beautiful if you were belly-empty, hollow-hungry. I learned to understand Cézanne much better and to see truly how he made landscapes when I was hungry.
