First, John Updike:
Ancient religion and modern science agree: we are here to give praise. Or, to slightly tip the expression, to pay attention. Without us, the physicists who have espoused the anthropic principle tell us, the universe would be unwitnessed, and in a real sense not there at all. It exists, incredibly, for us. This formulation (knowing what we know of the universe’s ghastly extent) is more incredible, to our sense of things, than the Old Testament hypothesis of a God willing to suffer, coddle, instruct, and even (in the Book of Job) to debate with men, in order to realize the meager benefit of worship, of praise for His Creation. What we beyond doubt do have is our instinctive intellectual curiosity about the universe from the quasars down to the quarks, our wonder at existence itself, and an occasional surge of sheer blind gratitude for being here.
Now, Charles Bukowski:
We are here to unlearn the teachings of the church, state, and our educational system.
We are here to drink beer.
We are here to kill war.
We are here to laugh at the odds and live our lives so well that Death will tremble to take us.
We are here to read these words from all these wise men and women who will tell us that we are here for different reasons and the same reason.
Which to embrace? I don't see it as an either/or proposition. I choose both. Some days, I want to marvel at the universe and bask in the idea that it exists because we are here to witness it.
And some days, I just want a beer.
