Albert Camus said this quote

If Aliosha had come to the conclusion that neither God nor immortality existed, he would immediately have become an atheist and a socialist. For socialism is not only a question of the working classes; it is above all, in its contemporary incarnation, a question of atheism, a question of the tower of Babel, which is constructed without God's help, not to reach to the heavens, but to bring the heavens down to earth.
