And if there's no God, well, we just have to blame the way the world is. Samuel Beckett wrote a play which expresses this point of view. It's called Breath and it lasts all of thirty-five seconds. The curtain goes up, and the stage is in darkness. There's a second cry, and the play is over.
Life is over in a single breath, and at the heart of it is nothing more than a pile of garbage.
If Beckett is right, then it's no wonder we have a hard time hanging on to goodness, truth and beauty. But it's difficult to argue that human beings have nothing to do with the state of world. Most people would agree that human beings share at least some of the blame. Maybe what's wrong is a lack of education. That would be another way to improve society.
