Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand.

I have often noticed that we are inclined to endow our friends with the stability of type that literary characters acquire in the reader's mind. No matter how many times we reopen 'King Lear,' never shall we find the good king banging his tankard in high revelry, all woes forgotten, at a jolly reunion with all three daughters and their lapdogs. Never will Emma rally, revived by the sympathetic salts in Flaubert's father's timely tear. Whatever evolution this or that popular character has gone through between the book covers, his fate is fixed in our minds, and, similarly, we expect our friends to follow this or that logical and conventional pattern we have fixed for them.

“If you want to teach your children that they are the tools of God, you had better not teach them that they are God's rifles, or we will have to stand firmly opposed to you: your doctrine has no glory, no special rights, no intrinsic and inalienable merit. If you insist on teaching your children false-hoods—that the Earth is flat, that "Man" is not a product of evolution by natural selection—then you must expect, at the very least, that those of us who have freedom of speech will feel free to describe your teachings as the spreading of falsehoods, and will attempt to demonstrate this to your children at our earliest opportunity. Our future well-being—the well-being of all of us on the planet—depends on the education of our descendants.”

Language as putative science. - The significance of language for the evolution of culture lies in this, that mankind set up in language a separate world beside the other world, a place it took to be so firmly set that, standing upon it, it could lift the rest of the world off its hinges and make itself master of it. To the extent that man has for long ages believed in the concepts and names of things as in aeternae veritates he has appropriated to himself that pride by which he raised himself above the animal: he really thought that in language he possessed knowledge of the world. The sculptor of language was not so modest as to believe that he was only giving things designations, he conceived rather that with words he was expressing supreame knowledge of things; language is, in fact, the first stage of occupation with science. Here, too, it is the belief that the truth has been found out of which the mightiest sources of energy have flowed. A great deal later - only now - it dawns on men that in their belief in language they have propagated a tremendous error. Happily, it is too late for the evolution of reason, which depends on this belief, to be put back. - Logic too depends on presuppositions with which nothing in the real world corresponds, for example on the presupposition that there are identical things, that the same thing is identical at different points of time: but this science came into existence through the opposite belief (that such conditions do obtain in the real world). It is the same with mathematics, which would certainly not have come into existence if one had known from the beginning that there was in nature no exactly straight line, no real circle, no absolute magnitude.

We all think we understand each other,' Kin heard Silver say. 'We eat together, we trade, many of us pride ourselves on having alien friends - but all this is only possible, only possible, Kin, because we do not fully comprehend the other. You've studied Earth history. Do you think you could understand the workings of of the mind of a Japanese warrior a thousand years ago? But he is as a twin to you compared with Marco, or with myself. When we use the word "cosmopolitan" we use it too lightly - it's flippant, it means we're galactic tourists who communicate in superficialities. We don't comprehend. Different worlds, Kin. Different anvils of gravity and radiation and evolution.

Forget the buildings and the monuments. Let the softness of dark come in, all those light-years between stars and planets. Cities were the works of men but the earth before and after those cities, outside and beneath and around them, was the dream of a sleeping leviathan--it was god sleeping there and dreaming, the same god that was time and transfiguration. From whatever dreamed the dream at the source, atom or energy, flowed all the miracles of evolution--tiger, tiger burning bright, the massive whales in the deep, luminescent specters in their mystery. The pearls that were their eyes, their tongues that were wet leaves, their bodies that were the bodies of the fantastic. Spectacular bestiaries of heaven, the limbs and tails of the gentle and the fearsome, silent or raging at will . . . they could never be known in every detail and they never should be.

Not enough books focus on how a culture responds to radically new ideas or discovery. Especially in the biography genre, they tend to focus on all the sordid details in the life of the person who made the discovery. I find this path to be voyeuristic but not enlightening. Instead, I ask, After evolution was discovered, how did religion and society respond? After cities were electrified, how did daily life change? After the airplane could fly from one country to another, how did commerce or warfare change? After we walked on the Moon, how differently did we view Earth? My larger understanding of people, places and things derives primarily from stories surrounding questions such as those.
