"From observation I would say that people may possibly be divided into two general groups; those who, to use one of the terms of the jargon of psychology, identify themselves with, that is, place themselves in the position of, animals, and those who identify themselves with human beings.

Ernest Hemingway, "Death in the Afternoon", Chapter 1
"I nearly always find, when I ask a vegetarian if he is a socialist, or a socialist if he is a vegetarian, that the answer is in the affirmative."
