From The Four Fists in F. Scott Fitzgerald’s Flappers and Philosophers. This being the conclusion of the story, there’s something in the way of a spoiler so the (very brief) full tale can be read here instead.

The setup is a charmingly simple morality tale where a man’s social and moral failings always earn him a punch when manifested. Each punch yields a life-reforming reflection and he goes forward a better man, having shed another bad quality.

I suppose that there’s a caddish streak in every man that runs crosswise across his character and disposition and general outlook. With some men it’s secret and we never know it’s there until they strike us in the dark one night. But Samuel’s showed when it was in action, and the sight of it made people see red. He was rather lucky in that, because every time his little devil came up it met a reception that sent it scurrying down below in a sickly, feeble condition. It was the same devil, the same streak that made him order Gilly’s friends off the bed, that made him go inside Marjorie’s house.

If you could run your hand along Samuel Meredith’s jaw you’d feel a lump. He admits he’s never been sure which fist left it there, but he wouldn’t lose it for anything. He says there’s no cad like an old cad, and that sometimes just before making a decision, it’s a great help to stroke his chin. The reporters call it a nervous characteristic, but it’s not that. It’s so he can feel again the gorgeous clarity, the lightning sanity of those four fists.

From The Great Gatsby, overall better observed but shallower than I remembered:

No telephone message [from Daisy] arrived but the butler went without his sleep and waited for it until four o’clock—until long after there was any one to give it to if it came. I have an idea that Gatsby himself didn’t believe it would come and perhaps he no longer cared. If that was true he must have felt that he had lost the old warm world, paid a high price for living too long with a single dream. He must have looked up at an unfamiliar sky through frightening leaves and shivered as he found what a grotesque thing a rose is and how raw the sunlight was upon the scarcely created grass. A new world, material without being real, where poor ghosts, breathing dreams like air, drifted fortuitously about . . . like that ashen, fantastic figure gliding toward him through the amorphous trees.

From The Great Gatsby:

Reserving judgments is a matter of infinite hope. I am still a little afraid of missing something if I forget that, as my father snobbishly suggested, and I snobbishly repeat, a sense of the fundamental decencies is parcelled out unequally at birth.
