“If instead of arranging the atoms in some definite pattern, again and again repeated, on and on, or even forming little lumps of complexity like the odor of violets, we make an arrangement which is always different from place to place, with different kinds of atoms arranged in many ways, continually changing, not repeating, how much more marvelously is it possible that this thing might behave? Is it possible that that "thing" walking back and forth in front of you, talking to you, is a great glob of these atoms in a very complex arrangement, such that the sheer complexity of it staggers the imagination as to what it can do? When we say we are a pile of atoms, we do not mean we are merely a pile of atoms, because a pile of atoms which is not repeated from one to the other might well have the possibilities which you see before you in the mirror.”

“All the green in the planted world consists of these whole, rounded chloroplasts wending their ways in water. If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring's center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its exact place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish's tail.”

“The body is a fortuitous concourse of atoms. There is no death for the body, only an exchange of atoms. Their changing places and taking different forms is what we call 'death.' It's a process which restores the energy level in nature that has gone down. In reality, nothing is born and nothing is dead.”

“We are all just complicated arrangements of atoms and subatomic particles. We don't live...but our atoms do move about in such a way as to give us identity and consciousness. We don't die; our atoms just rearrange themselves. There is no God. There can be no God; it's ridiculous to think in terms of a superior being. An inferior being, maybe, because we, we who don't even exist, we arrange our lives with more order and harmony than God ever arranged the earth. We measure; we plot; we create wonderful new things. We are the architects of our own existence. What a lunatic concept to bow down before a God who slaughters millions of innocent children, slowly and agonizingly starves them to death, beats them, tortures them, rejects them. What folly to even think that we should not insult such a God, damn him, think him out of existence. It is the duty of all human beings to think God out of existence. Then we have a future. Because then - and only then - do we take full responsibility for who we are.”

“I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously… The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big.”

“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.”
