In Margaret Atwood's "Oryx and Crake," the character Crake emphasizes the necessity of barriers in society. He suggests that the walls and bars are not just a means to protect the inhabitants from the outside world, but they also serve to contain those who pose a threat to societal order. This statement reflects a deeper philosophical understanding of human nature and the complexities of modern life.

Crake's perspective indicates that mankind requires boundaries to function effectively. These barriers are essential for both protection against external dangers and the management of the internal chaos that humans can create. His words reveal a cynical view of humanity, suggesting that without such constraints, society could descend into turmoil.
