In Cormac McCarthy's "All the Pretty Horses," the protagonist reflects on his experiences in the deserts of Mexico, recounting his battles and the horses that fell during these conflicts. He draws a deep connection between the souls of horses and those of men, suggesting that they share an intrinsic understanding of each other that often goes unrecognized. This connection indicates that both horses and men are intertwined in their love for war.

The protagonist argues that true learning comes from a profound emotional resonance, implying that only those with a certain depth can fully grasp the nature of war and its impact. He posits that understanding transcends mere experience; it requires a heart open to the complexities of existence. This exploration of war reveals deeper truths about humanity and the animal world, blurring the boundaries between them.
