Final answer:
Chapter 7 of 'All Quiet on the Western Front' demonstrates the young soldiers' pessimistic outlook towards life post-war in contrast to older men who might be more optimistic, reflecting a general disillusionment with the war and its aftereffects.
Step-by-step explanation:
In Erich Maria Remarque's All Quiet on the Western Front, Chapter 7 provides a stark look at the differing perspectives between young soldiers and older men regarding life post-war. The young soldiers, having been directly exposed to the brutal realities of trench warfare, have developed a rather pessimistic view of what life might be like after the war. In contrast, the older men—who either have not experienced the front lines or who harbor memories of past wars less mechanized and impersonal—might hold onto a more optimistic vision, though the text leans towards suggesting a generally somber outlook overall. This reflects a broader loss of innocence and a realization that the pre-war world they knew has irrevocably changed, a theme echoed in the disillusionment expressed in post-war literature by authors like F. Scott Fitzgerald and Ernest Hemingway.
