The Sirens of Titan by Kurt Vonnegut Jr.

And the machines did everything so expertly that they were finally given the job of finding out what the highest purpose of the creatures could be. So machines were made to serve higher purposes, too. But whenever they found a higher purpose, the purpose still wasn’t high enough. This left the creatures free to serve higher purposes. And, rather than serve such a low purpose, the creatures would make a machine to serve it. And every time they found out what seemed to be a purpose of themselves, the purpose seemed so low that the creatures were filled with disgust and shame. These creatures spent most of their time trying to find out what their purpose was. And these poor creatures were obsessed by the idea that everything that existed had to have a purpose, and that some purposes were higher than others. “Once upon a time on Tralfamadore there were creatures who weren’t anything like machines. No longer can a fool point to a ridiculous accident of good luck and say, 'Somebody up there likes me.' And no longer can a tyrant say, 'God wants this or that to happen, and anyone who doesn't help this or that to happen is against God.' O Lord Most High, what a glorious weapon is Thy Apathy, for we have unsheathed it, have thrust and slashed mightily with it, and the claptrap that has so often enslaved us or driven us into the madhouse lies slain!' -The prayer of the Reverend C.

Oh, Mankind, rejoice in the apathy of our Creator, for it makes us free and truthful and dignified at last. What could we do or say that could possibly interest Thee? Nothing. “Oh Lord Most High, Creator of the Cosmos, Spinner of Galaxies, Soul of Electromagnetic Waves, Inhaler and Exhaler of Inconceivable Volumes of Vacuum, Spitter of Fire and Rock, Trifler with Millennia - what could we do for Thee that Thou couldst not do for Thyself one octillion times better? Nothing.
