"Religions are for a day. They are the clouds. Humanity is the eternal blue. Religions are the waves of the sea. These waves depend upon the force and direction of the wind -- that is to say, of passion; but Humanity is the great sea. And so our religions change from day to day, and it is a blessed thing that they do. Why? Because we grow, and we are getting a little more civilized every day, -- and any man that is not willing to let another man express his opinion, is not a civilized man, and you know it. Any man that does not give to everybody else the rights he claims for himself, is not an honest man."
