“It is a slightly arresting notion that if you were to pick yourself apart with tweezers, one atom at a time, you would produce a mound of fine atomic dust, none of which had ever been alive but all of which had once been you.”

“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.”

“Everything had shattered. The fact that it was all still there — the walls and the chairs and the children’s pictures on the walls — meant nothing. Every atom of it had been blasted apart and reconstituted in an instant, and its appearance of permanence and solidity was laughable; it would dissolve at a touch, for everything was suddenly tissue-thin and friable.”

“If you had felt yourself sufficient, it would have been a proof that you were not.”

“Never be afraid to fall apart because it is an opportunity to rebuild yourself the way you wish you had been all along.”

“If we were to name the most powerful assumption of all, which leads one on and on in an attempt to understand life, it is that all things are made of atoms, and that everything that living things do can be understood in terms of the jigglings and wigglings of atoms.”
