“When we no longer look at an organic being as a savage looks at a ship, as at something wholly beyond his comprehension; when we regard every production of nature as one which has had a history; when we contemplate every complex structure and instinct as the summing up of many contrivances, each useful to the possessor, nearly in the same way as when we look at any great mechanical invention as the summing up of the labour, the experience, the reason, and even the blunders of numerous workmen; when we thus view each organic being, how far more interesting, I speak from experience, will the study of natural history become!”

“Every man that ever lived craved perfect happiness, the detective poignantly reflected. But how can we have it when we know we’re going to die? Each joy was clouded by the knowledge it would end. And so nature had implanted in us a desire for something unattainable? No. It couldn’t be. It makes no sense. Every other striving implanted by nature had a corresponding object that wasn’t a phantom. Why this exception? the detective reasoned. It was nature making hunger when there wasn’t any food. We continue. We go on. Thus death proved life.”

“We are engaged here in the most important pusuit in history. The search for meaning. What is What is the nature of being a person? What is the best way to go about being a person?How did we come to be, and wha will become of us when we are no longer? In short: What are the rules this game, and how might we best play it?”

“We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.”

“Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each so atomically numerous and so vigorously recycled at death that a significant number of our atoms - up to a billion for each of us, it has been suggested - probably once belonged to Shakespeare. A billion more each came from Buddha and Genghis Khan and Beethoven, and any other historical figure you care to name. So we are all reincarnations - though short-lived ones. When we die, our atoms will disassemble and move off to find new uses elsewhere - as part of a leaf or other human being or drop of dew.”

“I must talk, and you must listen, for we are engaged here in the most important pursuit in history: the search for meaning. What is the nature of being a person? What is the best way to go about being a person? How did we come to be, and what will become of us when we are no longer? In short: What are the rules of this game, and how might we best play it?”
