An illustration of the problems associated with dualism as set out by Plato and René Descartes by means of a theoretical model of the mutual contact and interaction between the material world and the information world, 3. An explanation of the historical view of R. G. Collingwood through informationalism, 4. A discussion of the basic concepts for Humanistic Informatics which is under construction, and 5. A proposal of some approach to the new subject in information science.
