“In trying to explain life we have reduced it to a series of chemical reactions, whether it be the burning of glucose in mitochondria to create energy, or the folding of proteins to make bile, or pollen, or blood. Zoom out to where we perceive things, the titanic mathematics of it all is silent. We have twisted our thoughts and feelings into all sorts of psychological origami about whether these things are a result of evolution, intelligent design, or creation ex nihilo, and for all we know, our little planet is the only place that holds all of this wonder in a void that is too staggeringly huge to conceive.”

“Anybody who has done high school physics knows Newton’s Third Law. For every action there is an equal and opposite reaction. You push against a wall; it pushes back against you. I love the poetry hidden in these truths, in the many laws we’ve discovered that underpin the universal fabric. We search for meaning ever hungrier, perhaps even with desperation: the symmetry in the equations freaks us out; for all we know, there is just us on this lonely little marble in the inky void.”

“It’s tragic that most of us spend our private lives paradoxically thinking something is watching us and permanently disapproving. We say we believe in benevolent deities but smear them with hate and the power to smite. We see sin everywhere, when the only sin is when we forget to treat each other with respect. That is the sad secret that makes the Universe vulnerable.”

“My mother once said if you can’t handle the fact that your world-view might be entirely inaccurate, you are not worthy of believing in it.”

“I’ve whittled my fascination with the cosmos down to this mantra: we can imagine the Universe as a giant void racing away from us at a frightening speed, or it could occur to us that, in fact, it is wrapped around us in all directions. Then, no matter where we are, we are at the centre of something wonderful. And that’s how I’ve always thought about it.”

“Tears are a wonderful thing; they wash, they warm, they are the rivers that run through our minds, seeking release. In their salinity they remind us that we came from the sea. Our cells know this, and go about their machinations, ceaselessly recreating the primordial brine. We are water, whether or not the Spirit of God once hovered formless and magnificent above the idea of us, in some ancient place before the Singularity uncoiled itself into space and time.”

“We get sombre about death. Think about Charon the ferryman rowing the souls across the Styx to the Isle of the Dead. Pretty grim stuff. Unless you think that, perhaps, at times, old Charon rows souls back to the land of the living too. Perhaps I have merely gone to rest awhile…”
