How does the following quote from A Farewell to Arms illustrate the effect new methods of warfare had on people’s beliefs? “Change was the only constant for Americans in the early 20th century. In 30 short years, they faced a world war, an economic boom followed by the Great Depression, shifting attitudes toward women’s place in society, and a mass culture that isolated and alienated the individual. In this swirl of uncertainty, traditional values seemed to slip out of reach or were actively discarded as Americans—writers and non-writers alike—searched for truths in what felt like a whole new world.”

The new methods of warfare affected people's beliefs. The given quote reflects this change in people's beliefs towards warfare.

Explanation:

World War I was a new kind of war waged where many nations were involved and took millions of lives. With a new kind of war came new weapons such as machine guns, poison gases, submarines, and airplane bombers.

"A Farewell to Arms" is a novel written by Ernest Hemingway. The novel is about a young American named Frederic Henry, who served as a second lieutenant in the Italian army in the war. The new era of war and new methods of warfare changed American's attitudes towards war. They became hedonists, politics became corrupted, ruthless business practices were being practiced.
