Abstract
Most of definitions presented for material/immaterial thing have a common form: first they define material thing, then they define immaterial thing as a thing that is not material. There is a common objection to these kind of definitions: all of them are such that we cannot define something between material thing and immaterial thing. In this research we try to investigate common definitions of material/immaterial thing, then web prove that according to Mulla Sadra''s viewpoint about Substantial Motion of human soul, we should define some levels between pure material and pure immaterial, In fact there should be a spectrum beginning from pure material thing and ending to pure immaterial thing. Then we show that this new viewpoint to definition of material/immaterial thing (spectrum view) is not compatible with traditional definition system that uses Alhasr al''Aghi. Finally we propose a new approach toward definition of immaterial (and material) thing using fuzzy logic.
