Paul Hackett is the originator and developer of the Declarative mapping Approach to social researcher and the Declarative Mapping Sentence (DMS) for guiding and interpreting qualitative and philosophical research enquiries. In my research and publications, I consider the use of categorial ontologies/mereologies in the understanding of behaviour and experience. Most recently I have focussed upon the perception and understanding of abstract fine art and avian behaviour and cognition. In Facet Theory and the Mapping Sentence: Evolving Philosophy, Use and Application I look at the development of facet theory viewing philosophical/ psychological categorisation using a mapping sentence.
