His Creed

"While I am opposed to all orthodox [religious] creeds, I have a creed myself; and my creed is this. Happiness is the only good. The time too be happy is now. The place to be happy is here. The way to be happy is to make others so. This creed is somewhat short, but it is long enough for this life, strong enough for this world. If there is another world, when we get there we can make another creed." [emphasis mine]
