Saul Bellow once remarked that death is essential for our understanding of life, serving as a contrast that allows us to truly see and appreciate our existence. This perspective suggests that mortality is not merely an endpoint, but rather a fundamental aspect that enriches our experiences and insights. It reminds us that life’s value can often be discerned in the face of its inevitable conclusion.

In Christopher Hitchens' book "Mortality," this idea is explored further. The inevitability of death shapes our lives, providing context and significance to our actions and beliefs. Hitchens reflects on the profound impact that awareness of mortality has on human behavior, urging readers to embrace life fully while acknowledging the shadows cast by death.
