| Research Abstract |
To set up a framework within which the discussion of the use of Japanese and English i possible in terms of flow of information, we worked in this year on the nature of information and information flow and the structure of action in general and speech acts in particular.
Information is analyzed with respect to two different concerns : information carriers, ie physical objects which convey information and information content, ie states of affairs in the world. We take that the former only represents the latter in virtue of the circumstances in which the former occurs. We define the flow of information as two different information carriers representing the same state of affairs in virtue of the circumstances in which the carriers occur. The storage of information is a special case of flow of information in which the carriers are the same, or virtually the same.
Action is analyzed in terms of two aspects : the movements of the agent and the effects those movements take in the world. The latter is described in the form of "bring it about that", namely the form of propositional attitudes. The former is analyzed as a temporally and spatially structured set of the movements of the effectors which comprises an agent. The two aspects are bridged by the notion of the meanings of the movements, which also serves as a basis for the analysis of levels of action. The two sets of concepts will facilitate the target of this project soon.
We hope all this gives the basis for the analysis of the flow of information in different languages, which is our main aim of this project.
