I don't believe that Hemmingway and F. Scott hated each other, however it is widely known that F. Scott was one of Hemmingway's biggest rivals, along with Faulkner. One can also see from the writing styles of these two authors, that they have very different views about the world and human beings in general. It is said that this piece of dialogue from "The Snows of Kilaminjaro" was actually a conversation between Hemmingway and Fitzgerald: "The very rich are different form you and me." "Yes, they have more money" This conversation alone shows the main difference between the two men.

I don't think Hem hated F. Scott. He had a problem with guys that couldn't hold their liquor and FSF was not ever very good at that. Hem also didn't like what he perceived as F. Scott's lax work ethic. In the Parisian days, the guy seemed to talk more about writing than actually write. And FSF was a little jealous that Hem was enjoying the success of The Sun Also Rises and FSF was blocked at the time. Then there was high-maintenance Zelda. I think Hem recongnized FSF's talent and tried to help him. Perkins probably encouraged the relationship, thinking Hem could get the guy off his ass and producing again. They went trout fishing in northern Spain together, camping, partying in the village, etc. You don't do that with a guy you hate. FSF was also a little insecure about his manhood, as he drunkenly verbalized one night in a Paris bistro men's room, which probably shocked Hem. But Hem pulled it together. They were taking a piss and FSF was whining about how small his penis was, among other things, and Hem just looked at him and said, "Of course it looks small, dumbass, you're looking down on it. They all look small from that angle. You worry too much." You don't help a guy out with a problem like that if you hate him. I think Hem was disgusted with FSF at times, and even lost patience with him enough to trash him a little, but I think he actually liked the guy.

Hemingway did, however, try to destroy almost everyone who ever tried to help him. Sherwood Anderson, for example (who was an early advocate of EMH's work), got skewered in the pages of "Torrents of Spring." Gertrude Stein (who taught EMH how to see clearly, by suggesting he look at paintings) was famously reduced by Hemingway into the witticism, "A bitch is a bitch is a bitch." In this vein, don't forget the gratuitous "Poor Scott Fitzgerald" remark in the short story, "Snows of K --" (I can never spell that placename without looking it up, and it's too late for that now). The business, in "A Movable Feast," about FSF's equipment is in keeping with this trend.
