"The stuff of anthropology—the traditions, the myths, the crafts, the language, the rituals—is to me but the froth on the surface. Beneath lie giant themes of humanity that are the same everywhere and that are characteristically male and female. To a Martian an anthropologist studying the differences between races would seem like a farmer studying the differences between each of the wheat plants in his field. The Martian is much more interested in the typical wheat plant. It is the human universals, not the differences, that are truly intriguing."
