When you look more generally at life on Earth, you find that it is all the same kind of life. ...It uses about fifty fundamental biological building blocks, organic molecules. ...with trivial exceptions, all organisms on Earth use... an enzyme, to control the rate and direction of the chemistry of life. ...a nucleic acid to encode the hereditary information ...the identical code book for translating nucleic acid language into protein language. ...At the molecular level, we are all virtually identical.

When you begin to read a poem you are entering a foreign country whose laws and language and life are a kind of translation of your own; but to accept it because its stews taste exactly like your old mother's hash, or to reject it because the owl-headed goddess of wisdom in its temple is fatter than the Statue of Liberty, is an equal mark of that want of imagination, that inaccessibility to experience, of which each of us who dies a natural death will die.

Just as organic species evolve toward the use of greater densities of a wider variety of free-energy sources in their environment, so human societies develop to access, store, and use in greater densities larger quantities of free energy through the ongoing improvement of their technologies. As a consequence societies, the same as natural systems, tend to grow larger in size, develop more intricate relations among their diverse components, and create more massive and flexible modes of interaction among them.

And I often dream of chemistry at night, dreams that conflate the past and the present, the grid of the periodic table transformed to the grid of Manhattan. [...] Sometimes, too, I dream of the indecipherable language of tin (a confused memory, perhaps, of its plaintive "cry”). But my favorite dream is of going to the opera (I am Hafnium), sharing a box at the Met with the other heavy transition metals-my old and valued friends-Tantalum, Rhenium, Osmium, Iridium, Platinum, Gold, and Tungsten.

On the geometric level, we see certain physical elements repeated endlessly, combined in an almost endless variety of combinations... It is puzzling to realize that the elements, which seem like elementary building blocks, keep varying, and are different every time that they occur .... If the elements are different every time that they occur, evidently then, it cannot be the elements themselves which are repeating in a building or town; these so-called elements cannot be the ultimate "atomic" constituents of space.

Such is the common process of marriage. A youth and maiden meeting by chance, or brought together by artifice, exchange glances, reciprocate civilities, go home, and dream of one another. Having little to divert attention, or diversify thought, they find themselves uneasy when they are apart, and therefore conclude that they shall be happy together. They marry, and discover what nothing but voluntary blindness had before concealed; they wear out life in altercations, and charge nature with cruelty.
Samuel Johnson
