" I don't know. Things don't have purposes, as if the universe were a machine, where every part has a useful function. What's the function of a galaxy? I don't know if our life has a purpose and I don't see that it matters. What does matter is that we're a part. Like a thread in a cloth or a grass-blade in a field. It IS and we ARE. What we do is like wind blowing on the grass. "

― Ursula K. Le Guin , The Lathe of Heaven / The Dispossessed / The Wind's Twelve Quarters
