Qualitative thinking : an examination of the classificatory systems, evaluative systems and cognitive structures of the Yolnu people of North-east Arnhem Land

Abstract

This thesis is an analysis of the classificatory and evaluative systems used by the Yolnu people of Elcho Island in North-east Arnhem Land. In the process of examining these systems, I attempt to demonstrate how the Yolnu qualitative approach effects the meanings of the evaluations and classifications made. In Chapter One, I introduce the relationship between my thesis and current literature. I also give a brief outline of the physical and cultural environment from within which the Yolnu approach the world. Chapters Two to Five contain the discussion of systems of classification in each of four domains. These domains are normally considered as measurement, nl.llD.ber, colour and ethno-biology. In each of these, I analyse the systems used, drawing out the structures upon which those systems are established. The structures established in those four chapters are drawn together in the Conclusion. I demonstrate that the harmonious relation between the structures used in different domains indicates the existence of deeper common structures which, I argue, function at a cognitive level. My aim is thus to demonstrate the existence of these cognitive structures, and the effect on them of a qualitative mode of evaluation.
