“Cooks were the mitochondria of humanity; they had their own separate DNA, they floated in a cell and powered it but were not really of it.”

“I try to think up material that might apply to the subjects they are studying. How many mitochondria does it take to power a cell? One. Because mitochondria are the powerhouse of the cell. Not ready for prime time, that one.”

“The world outside had its own rules, and those rules were not human.”

“Separately they had different strengths. Together they were complete.”

“When I started reading the literature of molecular biology, I was stunned by certain descriptions. Admittedly, I was on the lookout for anything unusual, as my investigation had led me to consider that DNA and its cellular machinery truly were an extremely sophisticated technology of cosmic origin. But as I pored over thousands of pages of biological texts, I discovered a world of science fiction that seemed to confirm my hypothesis. Proteins and enzymes were described as 'miniature robots,' ribosomes were 'molecular computers,' cells were 'factories,' DNA itself was a 'text,' a 'program,' a 'language,' or 'data.' One only had to do a literal reading of contemporary biology to reach shattering conclusions; yet most authors display a total lack of astonishment and seem to consider that life is merely 'a normal physiochemical phenomenon.”

“When you feel someone else's pain and joy as powerfully as if it were your own, then you know you really loved them.”
