Final answer:
American modernist writers perceived the world as chaotic due to rapid societal changes, the trauma of World War I, and the experimental nature of modernist literature.
Step-by-step explanation:
American modernist writers perceived the world as chaotic in the early 20th century due to several factors. First, the two decades prior to World War I were characterized by rapid changes in American society, such as western expansion, technological advancements, and the rise of big business. These changes caused a sense of disorientation and instability, which influenced the writers of the time to explore the chaos and uncertainty in their works.
Second, the experiences of World War I had a profound impact on the perception of the world. The war brought destruction, loss, and disillusionment, leading to a sense of betrayal and questioning of the values and traditions that had previously been upheld. This disillusionment and the trauma of war contributed to a view of the world as chaotic and unpredictable.
Lastly, modernist writers were also influenced by the general cultural and intellectual movements of the time. Modernism as a literary movement sought to break away from traditional forms and explore new ideas and techniques. The experimental and fragmented nature of modernist literature reflected the sense of fragmentation and chaos in the world.
