“The shapes of molecules influence their behavior and function, especially the ease with which they can fit into various guest-host configurations important in biology and biochemistry.”

“I can see no practical application of molecular biology to human affairs… DNA is a tangled mass of linear molecules in which the informational content is quite inaccessible.”

“No serious student of human behavior denies the potent influence of evolved biology upon our cultural lives. Our struggle is to figure out how biology affects us, not whether it does.”

“In the near future, neurobiology will address a matter of more general and fundamental importance: the biology of human mental processes. …Psychology and psychiatry can illuminate and define for biology the mental functions that need to be studied if we are to have a meaningful and sophisticated understanding of the biology of the human mind.”

“What is pleasanter than the tie of host and guest?”

“It is good to dress in fair clothes to dine with friends. It honors your host, if you are a guest; and your guest if you are a host. And both adorn the feast, and so celebrate the gifts of the world.”

“For a host, above all, must be kind to his guests.”

“The market does not exist in the pure state. It is shaped by the cultural configurations which define it and give it direction.”

“The shaping influence of economic change can of course be distinguished, as most notably in the period with which this book is concerned. But the difficulty lies in estimating the final importance of a factor which never, in practice, appears in isolation.”

“Women watched for the spectacular performances of the men, and there can be no reasonable doubt that the presence of an audience is a very important factor in shaping the men's behavior. In fact, it is probable that the men are more exhibitionistic because the women admire their performances. Conversely, there can be no doubt that the spectacular behavior is a stimulus which summons the audience together, promoting in the women the appropriate behavior.”
