A soldier who constantly reflected upon the knee-smashing, widow-making characteristics of his weapon, or who always thought of the enemy as a man exactly as himself, doing much the same task and subjected to exactly the same stresses and strains, would find it difficult to operate effectively in battle... Without the creation of abstract images of the enemy, and without the depersonalization of the enemy during training, battle would become impossible to sustain. But if the abstract image is overdrawn or depersonalization is stretched into hatred, the restraints on human behavior in war are easily swept aside. If, on the other hand, men reflect too deeply upon the enemy's common humanity, then they risk being able to proceed with the task whose aims may be eminently just and legitimate. This conundrum lies, like a Gordian knot linking the diverse strands of hostility and affection, at the heart of a soldier's relationship with the enemy.
