Would God give a bird wings and make it a crime to fly? Would he give me brains and make it a crime to think?

Don't you know that if people could bottle the air they would? Don't you know that there would be an American Air-bottling Association?

If there be gods we cannot help them, but we can assist our fellow men. We cannot love the inconceivable, but we can love wife and child and friend.
