“An existant can never justify the existence of another existant.”

“Existence is an imperfection.”

“Existence is prior to essence.”

“I exist, that is all, and I find it nauseating.”

“What do we mean by saying that existence precedes essence? We mean that man first of all exists, encounters himself, surges up in the world-and defines himself afterward.”

“My thought is me: that's why I can't stop. I exist because I think… and I can't stop myself from thinking. At this very moment - it's frightful - if I exist, it is because I am horrified at existing. I am the one who pulls myself from the nothingness to which I aspire.”

“All men are Prophets or else God does not exist.”
