“All our misery comes from wanting at all costs to go on being Tom, Dick, or Harry, year in, year out. This body of ours, this disguise put on my common jumping molecules, is in constant revolt against the abominable farce of having to endure. Our molecules, the dears, want to get lost in the universe as fast as they can! It makes them miserable to be nothing but "us," the jerks of infinity. We'd burst if we had the courage, day after day we come very close to it. The atomic torture we love so is locked up inside us by our pride.”

“When you stop to examine the way in which our words are formed and uttered, our sentences are hard-put to it to survive the disaster of their slobbery origins. The mechanical effort of conversation is nastier and more complicated than defecation. That corolla of bloated flesh, the mouth, which screws itself up to whistle, which sucks in breath, contorts itself, discharges all manner of viscous sounds across a fetid barrier of decaying teeth—how revolting! Yet that is what we are adjured to sublimate into an ideal. It's not easy. Since we are nothing but packages of tepid, half-rotted viscera, we shall always have trouble with sentiment. Being in love is nothing, its sticking together that's difficult. Feces on the other hand make no attempt to endure or grow. On this score we are far more unfortunate than shit; our frenzy to persist in ourpresent state—that's the unconscionable torture. Unquestionably we worship nothing more divine than our smell.

“I am a collection of water, calcium and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label. But is that all? Is there nothing in here but molecules? Some people find this idea somehow demeaning to human dignity. For myself, I find it elevating that our universe permits the evolution of molecular machines as intricate and subtle as we.But the essence of life is not so much the atoms and simple molecules that make us up as the way in which they are put together. Every now and then we read that the chemicals which constitute the human body cost ninety-seven cents or ten dollars or some such figure; it is a little depressing to find our bodies valued so little. However, these estimates are for human beings reduced to our simplest possible components. We are made mostly of water, which costs almost nothing; the carbon is costed in the form of coal; the calcium in our bones as chalk; the nitrogen in our proteins as air (cheap also); the iron in our blood as rusty nails. If we did not know better, we might be tempted to take all the atoms that make us up, mix them together in a big container and stir. We can do this as much as we want. But in the end all we have is a tedious mixture of atoms. How could we have expected anything else?”

“The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.”

“The days, the weeks, the years out here shall come back again, and our dead comrades shall then stand up again and march with us, our heads shall be clear, we shall have a purpose, and so we shall march, our dead comrades beside us, the years at the Front behind us:—against whom, against whom?”
