In Steinbeck's "The Moon Is Down," the character Lanser expresses a cynical view of human nature, asserting that there are no truly peaceful or friendly individuals. This perspective suggests a deep skepticism about the goodness of people, emphasizing their propensity for conflict and hostility. Lanser's statement challenges the idealistic notions of camaraderie and harmony among individuals, urging readers to confront a harsher reality.

The quote highlights a theme central to the book: the complexities of human relationships during times of war and oppression. It suggests that, in times of turmoil, the veneer of friendliness can quickly disappear, leading to a more primal struggle for survival and power. Steinbeck's exploration of these themes invites readers to reflect on the nature of humanity and the moral choices people make under pressure.
