I've said before that I'm essentially a nihilist on the question of whether life has any greater meaning. I reject that there is any non-human power judging us, deciding if we are living correctly or not. From a universal perspective, it makes no difference how you live your life. You can be a nun, a ninja, or a nutcase, but hundred years from now all you'll be is dust.
But is the absence of greater meaning reason for despair?
Only if you think a blank sheet of paper is worthless. Which, as a writer, I definitely do not. A blank sheet of paper may be inherently devoid of meaning, but in the hands of men it can become the medium for a story or a drawing or a blueprint; it can be folded into an airplane or a hat. Love letters may be composed, yard sales and lost dogs may be advertised.
Men aren't lucky enough to be born as blank sheets. We're always going to wind up with culture and genetics scribbled all over our lives and actions. But, once you come to the realization that there is no higher outline for your life, that you are basically free to fill the pages of your existance anyway you wish, you can choose to treat your life as a medium to hold a work of art. Your body and mind can be used to love, to create, to share... or to rage and destroy.
And while there is no higher power to judge you, the same is true for literature, or music, or dance. We don't need a god to approve of these things; our fellow men are all the audience we need when we create art. In fact, sometimes we need no one's judgment but our own to feel happy with our creations. So it can be with our lives.
