How does Stefan Zweig use imagery in Beware of Pity?

Imagery

"I realized that there was no point in denying oneself a pleasure because it was denied another, in refusing to allow oneself to be happy because someone else was unhappy. I realized that all the time one was laughing and cracking silly jokes, somewhere in the world someone was lying at the point of death; that misery was lurking, people starving, behind a thousand windows; that there were such things as hospitals, quarries and coal-mines; that in factories, in offices, in prisons countless thousands toiled and moiled at every hour of the day, and that it would not relieve the distress of a single human being if yet another were to torment himself needlessly." p. 33

"No envy is more mean than that of small-minded beings when they see a neighbor lifted, as though borne aloft by angels, out of the dull drudgery of their common existence; petty spirits are more ready to forgive a prince the most fabulous wealth rather than a fellow sufferer beneath the same yoke the smallest degree of freedom." p. 118
