«In our ludicrous efforts to 'change' and be perfect, we try to fashion a perfect world for ourselves. We start to imagine that we are actually in control of our world, which is further from reality than an all-parrot moon landing. The universe, our universe, is out of our control. We live on a speck drifting around in an infinite vacuum with countless trillions of other specks. Our world is in a perpetual state of perfect chaos and entropy, with everything falling apart and dying and being born haphazardly. Meanwhile, we try to make life as neat and clean and orderly as a computer research facility, when in fact it is more like a junkyard. It always has been, and it always will be, no matter how much fussing and sweating and striving we do to make it different.»
