The symbol of a setting for a Hemingway story is a boxing ring; for Borges, a library. On the other hand I think Nabokov was a writer quite close to Borges. He had the same rich literary culture, moved with great ease in different languages and traditions, and had a playful approach to literature-literature as an intellectual game, through which, of course, the real truths could appear. But apparently the game was for Nabokov just an exercise devoid of moral substance.
