Religion is only the illusory sun which revolves round man as long as he does not revolve round himself.

The imaginary flowers of religion adorn man's chains. Man must throw off the flowers, and also the chains.

Religion is a matter between the man and his Maker.

Religion is for man and not man for religion.

Myth, the necessary prerequisite of any religion, is already paralyzed everywhere, and even in this domain the optimistic spirit, which we have just designated as the germ of destruction in our society, has attained the mastery.

Religion is the opiate of the masses.
