Adam Smith, the founder of classical economics, was certain that
humankind's knack for monetary exchange belonged to humankind alone.
''Nobody ever saw a dog make a fair and deliberate exchange of one bone
for another with another dog,'' he wrote. ''Nobody ever saw one animal
by its gestures and natural cries signify to another, this is mine,
that yours; I am willing to give this for that.'' But in a clean and
spacious laboratory at Yale-New Haven Hospital, seven capuchin monkeys
have been taught to use money, and a comparison of capuchin behavior
and human behavior will either surprise you very much or not at all,
depending on your view of humans.
The last paragraph is enough.
