Yesterday in a restaurant in Tokyo, someone at the table next to us lit up a cigarette. I asked my Japanese host if no one ever asked smokers to go outside. His answer took me by surprise: one is not allowed to smoke on the street. Inside is fine, outside is wrong. It’s the opposite of what we are used to in the West.
The point is not so much the reason for the Japanese rule (which is that a walking smoker often holds his or her cigarette at children’s eye level, hence may accidently blind a child – apparently, this has happened!), but the fact that cultural differences often baffle us. This is because we assume our own perspective to be the only one that matters or makes sense. The same applies very much to my field of primatology, which owes much to Japanese pioneers.
Today I met in Kyoto with my old friend Toshisada Nishida, who is a student of the late Jun’ichiro Itani, who in turn was the most prominent student of Kinji Imanishi, the founder of Japanese primatology. Imanishi was interested in the connection between primate behavior and human evolution well before Louis Leakey and others in the West, and had fewer inhibitions to speculate about it. In 1952, when European ethologists still worked on instinct theories and American behaviorists still trained rats to press levers, Imanishi wrote a little book that criticized the view of animals as mindless automatons. He inserted an imaginary debate between a wasp, a monkey, an evolutionist and a layman, in which the possibility was raised that animals other than ourselves might have culture. The proposed definition of culture was simple: if individuals learn from one another, their behavior may, over time, become different from that in other groups, thus creating a characteristic culture. Soon thereafter, his students demonstrated that the potato washing started by a juvenile female monkey on Koshima Island spread to other members of her troop. The troop had developed a potato washing culture. [Photo, taken by the author, shows Japanese macaques on Koshima Island are still washing potatoes half a century later.]
Imanishi was also the first to insist that observers give their animals names and follow them for years so that they understand their kinship relations. His concepts are now all around us: every self-respecting field worker conducts long-term studies based on individual identification, and the idea of cultural transmission in animals is one of the hottest topics of today. But that is now: at the time, all Imanishi got was ridicule.
