The story of Micronesia is one of fluidity and fusion. It is fluid in the basic sense of the sea as salt water, a body of fluid that allows for the passage of seacraft across what in the terms of Gilles Deleuze and Félix Guatarri (1988) we might understand as smooth space. The ocean is a space not striated by walls or fences as boundaries, but one where all the known world is the place of home; where nomads exist is large space from which they do not travel. We should be aware of the metaphorical use of some of these terms, the sea is not always smooth, but it is a space for movement, and the inhabitants of Micronesia are not regarded as nomads in the conventional sense, but their world has often been a large one allowing movement by judicious use of winds and currents that would often mean extended stays on islands that were not their homes: but, they were at home with the sea.

As salt and water fuse in the fluid of the ocean, so it is that I understand the story of Micronesia as one of fusion. As a concept in the study of human societies past and present, fusion allows us to think beyond boundaries, both of the body and of space.
