This is the crucial scene for Abbey’s argument that animals and human beings are equal. In
Desert Solitaire, readers see Abbey engaging in a variety of conversations, but never is he so forthright, talkative, and eager as with Moon-Eye, a creature incapable of language. Though it’s silly to reason with a horse, Abbey’s point here is that people should at least think of animals as deserving of logic. That way, people will have a better sense of how their own species is just one element of a wider natural order. Notably, “old man” is a phrase that stresses this equality, and “boiled egg” is a poetically outlandish phrase that captures the strangeness of this animal’s appearance.
