“How can a three-pound mass of jelly that you can hold in your palm imagine angels, contemplate the meaning of infinity, and even question its own place in the cosmos? Especially awe inspiring is the fact that any single brain, including yours, is made up of atoms that were forged in the hearts of countless, far-flung stars billions of years ago. These particles drifted for eons and light-years until gravity and change brought them together here, now. These atoms now form a conglomerate- your brain- that can not only ponder the very stars that gave it birth but can also think about its own ability to think and wonder about its own ability to wonder. With the arrival of humans, it has been said, the universe has suddenly become conscious of itself. This, truly, it the greatest mystery of all.”

“It was safe, with all the lights off and no one around to point and stare. In the night it's easy to indulge. It was just the two of us—we didn't have to think about who we were or what this meant or where it was going. It was like an escape. It's easy to forget at this moment billions of people exist and far-off galaxies are being born and stars collide. Kissing is its own kind of collision, it produces its own planetarium of lights inside your head. For me, it was like seeing colors for the first time after living in a black-and-white world. A single person can be just as wide and vast and spellbinding as any sky full of stars. They can make you think the world stops and night can last forever.",”

“All that can be cherished from this world, all that makes life worth living is that which is mined from its bowels through your own toil, fashioned from its clay by your own craft, fired in the kiln of your heart. Oh, how precious, how delightful a feast, the life that has been forged by its own master!”

“We have begun to contemplate our origins: starstuff pondering the stars; organized assemblages of ten billion billion billion atoms considering the evolution of atoms; tracing the long journey by which, here at least, consciousness arose.”

“Your brain never stops developing and changing. It's been doing it from the time you were an embryo, and will keep doing it all your life. And this ability, perhaps, represents its greatest strength.”

“Atoms, in short, are very abundant. They are also fantastically durable. Because they are so long lived, atoms really get around. Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each so atomically numerous and so vigorously recycled at death that a significant number of our atoms-- up to a billion for each of us, it has been suggested-- probably once belonged to Shakespeare.”
