“Every advance [in Science] will most likely tell us as much about ourselves as it will about the universe we inhabit. We are all collections of chemicals made in the cataclysmic explosions of stars; we are stardust, or nuclear waste, depending on your perspective.”

“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.”

“We ourselves are made of Stardust.”

“Cats make one of the most satisfying sounds in the world: they purr. [...] Almost all cats make us feel good about ourselves because they let us know they feel good about us, about themselves, and about our relationship with them. A purring cat is a form of high praise, like a gold star on a test paper. It is a reinforcement of soemthing we would all like to believe about ourselves -- that we are nice.”

“ It is difficult to see ourselves as we are. Sometimes we are fortunate enough to have good friends, lovers or others who will do us the good service of telling us the truth about ourselves. When we don't, we can so easily delude ourselves, lose a sense of truth about ourselves, and our conscience loses power and purpose. Mostly, we tell ourselves what we would like to hear. We lose our way.”

“What we become depends on what we read after all of the professors have finished with us. The greatest university of all is a collection of books.”
