"There will come a time when all of us are dead. All of us. There will come a time when there are no human beings remaining to remember that anyone ever existed or that our species ever did anything. There will be no one left to remember Aristotle or Cleopatra, let alone you. Everything that we did and built and wrote and thought and discovered will be forgotten and all of this will have been for naught. Maybe that time is coming soon and maybe it is millions of years away, but even if we survive the collapse of our sun, we will not survive forever. There was time before organisms experienced consciousness, and there will be time after. And if the inevitability of human oblivion worries you, I encourage you to ignore it. God knows that’s what everyone else does."
"It’s always seemed a little preposterous that Hamlet, for all his paralyzing doubt about everything, never once doubts the reality of the ghost. Never questions whether his own madness might not in fact be unfeigned."
"Your eye will no longer linger on the light, it will no longer trace constellations. You’ll care only about the darkness and you’ll watch it for hours, for days, maybe even for years, trying in vain to believe you’re some kind of indispensable, universe-appointed sentinel, as if just by looking you could actually keep it all at bay."
