Raymond Firth’s We, The Tikopia, first published in 1936, still sets the standard for detailed, nuanced, sensitive ethnography. As Malinowski’s student, Firth—who died in 2002 at the age of 100—was a hard-headed functionalist, whose forte was careful examination of cultural “institutions” and their effects on individuals as well as on other institutions. Suspicious of abstruse theoretical pronouncements, he presented his analyses in plain language and always situated them in relation to the “imponderabilia” of real people’s everyday lives. We, The Tikopia has been a foundational text for generations of anthropologists, and it helped to guide my research on three Polynesian outliers over the past four decades. Since the time of Firth’s initial fieldwork, conditions in the region have changed drastically, as even the most remote communities have become enmeshed in the world market economy. In 2007-08, I studied a revival of indigenous voyaging techniques on Taumako, a Polynesian community near Tikopia, in the southeastern Solomon Islands. I was struck by the extent to which the cash economy permeated Taumako life, altering the tone of kin relations in ways that would have been unimaginable on Tikopia in the 1920s—or even on Anuta, where I conducted research, in the 1970s. Here, I will examine Taumako kinship in light of the insights offered by Sir Raymond three quarters of a century ago and explore the changes to the kinship system brought about by new economic forces.
