The concept of "emptiness" was important to a "certain type of existentialist philosophy and some forms of the Death of God movement". Existentialism, the "philosophic movement that gives voice to the sense of alienation and despair", comes from "man’s recognition of his fundamental aloneness in an indifferent universe". People whose response to the sense of emptiness and aloneness is to give excuses live in bad faith; "people who face the emptiness and accept responsibility aim to live 'authentic' lives". Existentialists argue that "man lives in alienation from God, from nature, from other men, from his own true self." Crowded into cities, working in mindless jobs, and entertained by light mass media, we "live on the surface of life", so that even "people who seemingly have 'everything' feel empty, uneasy, discontented."
