This book investigates the notion of subjectivity from a pragmatic point of view. There have been attempts to reduce the notion of the speaker or subjectivity as a syntactic category, or to seek an explanation for it in semantic terms. However, in order to understand the vast range of subjectivity phenomena, it is more fruitful to examine how the attributes and the experience of the real speaker affect language. The volume provides a theoretical/methodological basis for the study of various aspects of language and discourse and applies these specifically to Japanese spoken discourse, for which the data are added in an appendix.
